Is there a way to search/find a specific managed navigation term by guid using server object model
This code
var termGuid = new Guid(fieldValue.TermGuid);
var navTermSet = TaxonomyNavigation.GetTermSetForWeb(SPContext.Current.Web, StandardNavigationProviderNames.GlobalNavigationTaxonomyProvider, true);
if (navTermSet == null) return String.Empty;
var navTerm = navTermSet.Terms.Where(c => c.Id == termGuid).FirstOrDefault();
if (navTerm == null) return String.Empty;
return navTerm.GetWebRelativeFriendlyUrl();
only works if the term is in the first level, if its deeper down in hierarchy it doesn't find it and I'm not seeing any other mechanism that gets me a flat list of terms
It looks like a severe limitation with API
When you're looking for a certain term and you don't know how deep this resides and wether it's a parent or child, this becomes more complicated. If the API has no direct way of getting all the terms, regardless wether they're child or parent, I guess your best option is to list them all yourself by looping all terms + children and then find them by Guid.
Below code can be used to list all terms. The code is taken and shortened for your ease from this article.
List<Term> allTerms = new List<Term>();
void BuildTermList()
{
SPSite thisSite = SPContext.Current.Site;
TaxonomySession session = new TaxonomySession (thisSite);
foreach (TermStore termStore in session.TermStores)
{
foreach (Group group in termStore.Groups)
{
foreach (TermSet termSet in group.TermSets)
{
foreach (Term term in termSet.Terms)
{
AddTermSet(term);
}
}
}
}
}
void AddTermSet(Term term)
{
allItems.Add(term);
foreach (Term t in term.Terms)
AddTermSet(t);
}
Now that you have the list you can query it. Hope this helps.

I'm using my OrganizationServiceContext implementation generated by the svcutil to retrieve entities from CRM:
context.new_productSet.First(p => p.new_name == "Product 1");
Is it possible to retrieve multiple entities with different attribute values at once - (smth like IN operator in SQL)?
Example: I would like to retrieve multiple products ("Product 1", "Product 2", ...) with a single call. The list of product names is dynamic, stored in an array called productNames.
No, you can't. CRM LINQ provider only allows variables to appear on the left side of expressions, while the right side must contain constants.
i.e.
Product.Where(e => e.Name == desiredName)
Is not supported and won't work (it will complain about using a variable on the right side of the comparison).
If you cannot avoid this kind of query, you have to .ToList() data first (this can lead to a huge result set and will probably turn up to be unconceivably slow):
Product.ToList().Where(e => e.Name == desiredName)
This will work, because now the .Where() is being applied on a List<> instead.
Another approach (I don't have data about performance, though) would be to create many queries, basically fetching the records one at a time:
// ... this is going to be a nightmare ... don't do it ...
var entities = new List<Product>();
entities.Add(Product.Where(e => e.Name == "Product 1"));
entities.Add(Product.Where(e => e.Name == "Product 2"));
Or use a QueryExpression like this (my personal favourite, because I always go late-bound)
var desiredNames = new string[]{"Product 1", "Product 2"};
var filter = new FilterExpression(LogicalOperator.And)
{
Conditions =
{
new ConditionExpression("name", ConditionOperator.In, desiredNames)
}
};
var query = new QueryExpression(Product.EntityLogicalName)
{
ColumnSet = new ColumnSet(true),
Criteria = filter
};
var records = service.RetrieveMultiple(query).Entities;
If combining Linq and Lambda expression is ok, it can be done. First you need to create an extension method:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Expressions;
namespace Kipon.Dynamics.Extensions.IQueryable
{
public static class Methods
{
public static IQueryable<TSource> WhereIn<TSource, TValue>(this IQueryable<TSource> source, Expression<Func<TSource, TValue>> valueSelector, IEnumerable<TValue> values)
{
if (null == source) { throw new ArgumentNullException("source"); }
if (null == valueSelector) { throw new ArgumentNullException("valueSelector"); }
if (null == values) { throw new ArgumentNullException("values"); }
var equalExpressions = new List<BinaryExpression>();
foreach (var value in values)
{
var equalsExpression = Expression.Equal(valueSelector.Body, Expression.Constant(value));
equalExpressions.Add(equalsExpression);
}
ParameterExpression p = valueSelector.Parameters.Single();
var combined = equalExpressions.Aggregate<Expression>((accumulate, equal) => Expression.Or(accumulate, equal));
var combinedLambda = Expression.Lambda<Func<TSource, bool>>(combined, p);
return source.Where(combinedLambda);
}
}
}
With this method in place, you can now use it against your context. First remember to import the namespace of the extension to make the method available on IQueryable:
using System.Linq;
using Kipon.Dynamics.Extensions.IQueryable;
public class MyClass
{
void myQueryMethod(CrmContext ctx, Guid[] contacts)
{
var accounts = (from a in ctx.accountSet.WhereIn(ac => ac.primarycontactid.id,contacts)
where a.name != null
select a).toArray();
}
}
There is no way you can hook into the Dynamics 365 Linq expression compiler, as far as I know, but the above code will execute in one request against the CRM, and take advantage
of the fact that you do not need to consider paging and more when working with Linq.
As you can see, there whereIn clause is added with a lambda style expression, where the rest of the query is using the Linq style.
When using QueryExpression, we can add condtionexpression for where clause. ConditionExpression takes a ConditionOperator enumerator, and we can use ConditionOperator.In. Below is how you initiate a conidtionExpression with an “In” operator, the third argument can be an array or collection.
ConditionExpression ce = new ConditionExpression("EntityName",
ConditionOperator.In, collectionObject);
Please see below for further explanation.
http://msdn.microsoft.com/en-us/library/microsoft.xrm.sdk.query.conditionexpression.conditionexpression.aspx
I do not know how to do this with Linq, as far as I know it is not possible.
It can be done with Query Expressions:
String[] productNames = new[] { "test1", "test2" };
QueryExpression products = new QueryExpression(Product.EntityLogicalName);
products.ColumnSet = new ColumnSet("name", "new_att1", "new_att2"); // fields to get
products.Criteria.AddCondition("name", ConditionOperator.In,
productNames.Cast<Object>().ToArray()); // filter by array
EntityCollection res = service.RetrieveMultiple(products);
IEnumerable<Product> opportunities = res.Entities
.Select(product => product.ToEntity<Product>()); // you can use Linq again from here
Is there a way to programmatically access the Label & Value fields that has been created as a custom Field in MS CRM Dynamics please?
I have added a custom field called "new_producttypesubcode" which, for example, has 2 options, Trophy = 1000000 and Kit = 10000001.
I am writing an import utility that mirrors products between the customers website and their CRM and I want to get a list of all possible product options in the CRM to see if they are matched in the website.
So, in essence I want to...
get the list of possible new_producttypesubcodes and their corresponding values.
Iterate through the product variants in the website.
if the product variant name matches any name in the list of new_producttypecodes then add the value 1000000
So, if I find a product added to the website and its marked as a "Trophy" and "Trophy" exists in the CRM then new OptionSetValue(100000001)
I hope that makes sense...
Thanks
This function retrieves a dictionary of possible values localised to the current user. Taken from: CRM 2011 Programatically Finding the Values of Picklists, Optionsets, Statecode, Statuscode and Boolean (Two Options).
static Dictionary<String, int> GetNumericValues(IOrganizationService service, String entity, String attribute)
{
RetrieveAttributeRequest request = new RetrieveAttributeRequest
{
EntityLogicalName = entity,
LogicalName = attribute,
RetrieveAsIfPublished = true
};
RetrieveAttributeResponse response = (RetrieveAttributeResponse)service.Execute(request);
switch (response.AttributeMetadata.AttributeType)
{
case AttributeTypeCode.Picklist:
case AttributeTypeCode.State:
case AttributeTypeCode.Status:
return ((EnumAttributeMetadata)response.AttributeMetadata).OptionSet.Options
.ToDictionary(key => key.Label.UserLocalizedLabel.Label, option => option.Value.Value);
case AttributeTypeCode.Boolean:
Dictionary<String, int> values = new Dictionary<String, int>();
BooleanOptionSetMetadata metaData = ((BooleanAttributeMetadata)response.AttributeMetadata).OptionSet;
values[metaData.TrueOption.Label.UserLocalizedLabel.Label] = metaData.TrueOption.Value.Value;
values[metaData.FalseOption.Label.UserLocalizedLabel.Label] = metaData.FalseOption.Value.Value;
return values;
default:
throw new ArgumentOutOfRangeException();
}
}
So you would then need to do something like:
Dictionary<String, int> values = GetNumericValues(proxy, "your_entity", "new_producttypesubcode");
if(values.ContainsKey("Trophy"))
{
//Do something with the value
OptionSetValue optionSetValue = values["Trophy"];
int value = optionSetValue.Value;
}
Yes, that data is all stored in the metadata for an attribute (SDK article). You have to retrieve the entity metadata for the entity and then find the attribute in the list. Then cast that attribute to a PicklistAttributeMetadata object and it will contain a list of options. I would mention that typically retrieving Metadata from CRM is an expensive operation, so think about caching.
private static OptionSetMetadata RetrieveOptionSet(IOrganizationService orgService,
string entityName, string attributeName)
{
var entityResponse = (RetrieveEntityResponse)orgService.Execute(
new RetrieveEntityRequest
{ LogicalName = entityName, EntityFilters = EntityFilters.Attributes });
var entityMetadata = entityResponse.EntityMetadata;
for (int i = 0; i < entityMetadata.Attributes.Length; i++)
{
if (attributeName.Equals(entityMetadata.Attributes[i].LogicalName))
{
if (entityMetadata.Attributes[i].AttributeType.Value ==
AttributeTypeCode.Picklist)
{
var attributeMD = (PicklistAttributeMetadata)
entityMetadata.Attributes[i];
return attributeMD.OptionSet;
}
}
}
return null;
}
Here is how to write the options to the console using the above call.
var optionSetMD = RetrieveOptionSet(orgService, "account", "accountcategorycode");
var options = optionSetMD.Options;
for (int i = 0; i < options.Count; i++)
{
Console.WriteLine("Local Label: {0}. Value: {1}",
options[i].Label.UserLocalizedLabel.Label,
options[i].Value.HasValue ? options[i].Value.Value.ToString() : "null");
}
I believe this works for global option set attributes as well, but if you know it is a global option set there is a different message for it that would probably a bit more efficient (SDK article).
I'm working on an app that reuses some code from a previous solution.
The idea is to show a user all of the lists of a certain type in all the webs in a site collection so that the user can aggregate some data.
static public List<SPListMeta> AllSiteAnnouncementsLists(ClientContext clientContext)
{
var returnList = new List<SPListMeta>();
var per = new BasePermissions();
per.Set(PermissionKind.Open);
if (clientContext.Site.RootWeb.DoesUserHavePermissions(per).Value)
{
var rootWebLists = clientContext.Site.RootWeb.Lists;
returnList.AddRange(from List oList in rootWebLists
where oList.DoesUserHavePermissions(SPBasePermissions.ViewListItems) &&
where oList.BaseTemplate == (int)ListTemplateType.Announcements
select new SPListMeta(oList));
var collWebs =
clientContext.Site.OpenWebById(clientContext.Site.RootWeb.Id).GetSubwebsForCurrentUser(null);
foreach(Web oWeb in collWebs)
{
}
}
return returnList;
}
The critical line that does not work and does not seem to have a replacement is
oList.DoesUserHavePermissions(SPBasePermissions.ViewListItems)
as this has been removed from the CSOM List object
What's the new way to do this?
The new way to check for permissions is:
List.EffectiveBasePermissions.Has(PermissionKind.Open)
I am building an asp.net site in .net framework 4.0, and I am stuck at the method that supposed to call a .cs class and get the query result back here is my method call and method
1: method call form aspx.cs page:
helper cls = new helper();
var query = cls.GetQuery(GroupID,emailCap);
2: Method in helper class:
public IQueryable<VariablesForIQueryble> GetQuery(int incomingGroupID, int incomingEmailCap)
{
var ctx = new some connection_Connection();
ObjectSet<Members1> members = ctx.Members11;
ObjectSet<groupMember> groupMembers = ctx.groupMembers;
var query = from m in members
join gm in groupMembers on m.MemberID equals gm.MemID
where (gm.groupID == incomingGroupID) && (m.EmailCap == incomingEmailCap)
select new VariablesForIQueryble(m.MemberID, m.MemberFirst, m.MemberLast, m.MemberEmail, m.ValidEmail, m.EmailCap);
//select new {m.MemberID, m.MemberFirst, m.MemberLast, m.MemberEmail, m.ValidEmail, m.EmailCap};
return query ;
}
I tried the above code with IEnumerable too without any luck. This is the code for class VariablesForIQueryble:
3:Class it self for taking anonymouse type and cast it to proper types:
public class VariablesForIQueryble
{
private int _emailCap;
public int EmailCap
{
get { return _emailCap; }
set { _emailCap = value; }
}`....................................
4: and a constructor:
public VariablesForIQueryble(int memberID, string memberFirst, string memberLast, string memberEmail, int? validEmail, int? emailCap)
{
this.EmailCap = (int) emailCap;
.........................
}
I can't seem to get the query result back, first it told me anonymous type problem, I made a class after reading this: link text; and now it tells me constructors with parameters not supported. Now I am an intermediate developer, is there an easy solution to this or do I have to take my query back to the .aspx.cs page.
If you want to project to a specific type .NET type like this you will need to force the query to actually happen using either .AsEnumerable() or .ToList() and then use .Select() against linq to objects.
You could leave your original anonymous type in to specify what you want back from the database, then call .ToList() on it and then .Select(...) to reproject.
You can also clean up your code somewhat by using an Entity Association between Groups and Members using a FK association in the database. Then the query becomes a much simpler:
var result = ctx.Members11.Include("Group").Where(m => m.Group.groupID == incomingGroupID && m.EmailCap == incomingEmailCap);
You still have the issue of having to do a select to specify which columns to return and then calling .ToList() to force execution before reprojecting to your new type.
Another alternative is to create a view in your database and import that as an Entity into the Entity Designer.
Used reflection to solve the problem:
A: Query, not using custom made "VariablesForIQueryble" class any more:
//Method in helper class
public IEnumerable GetQuery(int incomingGroupID, int incomingEmailCap)
{
var ctx = new some_Connection();
ObjectSet<Members1> members = ctx.Members11;
ObjectSet<groupMember> groupMembers = ctx.groupMembers;
var query = from m in members
join gm in groupMembers on m.MemberID equals gm.MemID
where ((gm.groupID == incomingGroupID) && (m.EmailCap == incomingEmailCap)) //select m;
select new { m.MemberID, m.MemberFirst, m.MemberLast, m.MemberEmail, m.ValidEmail, m.EmailCap };
//select new VariablesForIQueryble (m.MemberID, m.MemberFirst, m.MemberLast, m.MemberEmail, m.ValidEmail, m.EmailCap);
//List<object> lst = new List<object>();
//foreach (var i in query)
//{
// lst.Add(i.MemberEmail);
//}
//return lst;
//return query.Select(x => new{x.MemberEmail,x.MemberID,x.ValidEmail,x.MemberFirst,x.MemberLast}).ToList();
return query;
}
B:Code to catch objects and conversion of those objects using reflection
helper cls = new helper();
var query = cls.GetQuery(GroupID,emailCap);
if (query != null)
{
foreach (var objRow in query)
{
System.Type type = objRow.GetType();
int memberId = (int)type.GetProperty("MemberID").GetValue(objRow, null);
string memberEmail = (string)type.GetProperty("MemberEmail").GetValue(objRow, null);
}
else
{
something else....
}
The situation:
I have a bunch of Terms in the Term Store and a list that uses them.
A lot of the terms have not been used yet, and are not available yet in the TaxonomyHiddenList.
If they are not there yet they don't have an ID, and I can not add them to a list item.
There is a method GetWSSIdOfTerm on Microsoft.SharePoint.Taxonomy.TaxonomyField that's supposed to return the ID of a term for a specific site.
This gives back IDs if the term has already been used and is present in the TaxonomyHiddenList, but if it's not then 0 is returned.
Is there any way to programmatically add terms to the TaxonomyHiddenList or force it happening?
Don't use
TaxonomyFieldValue tagValue = new TaxonomyFieldValue(termString);
myItem[tagsFieldName] = tagValue;"
because you will have errors when you want to crawl this item.
For setting value in a taxonomy field, you have just to use :
tagsField.SetFieldValue(myItem , myTerm);
myItem.Update();"
Regards
In case of usage
string termString = String.Concat(myTerm.GetDefaultLabel(1033),
TaxonomyField.TaxonomyGuidLabelDelimiter, myTerm.Id);
then during instantiation TaxonomyFieldValue
TaxonomyFieldValue tagValue = new TaxonomyFieldValue(termString);
exception will be thrown with message
Value does not fall within the expected range
You have additionally provide WssId to construct term string like shown below
// We don't know the WssId so default to -1
string termString = String.Concat("-1;#",myTerm.GetDefaultLabel(1033),
TaxonomyField.TaxonomyGuidLabelDelimiter, myTerm.Id);
On MSDN you can find how to create a Term and add it to TermSet. Sample is provided from TermSetItem class description. TermSet should have a method CreateTerm(name, lcid) inherited from TermSetItem. Therefore you can use it in the sample below int catch statement ie:
catch(...)
{
myTerm = termSet.CreateTerm(myTerm, 1030);
termStore.CommitAll();
}
As for assigning term to list, this code should work (i'm not sure about the name of the field "Tags", however it's easy to find out the proper internal name of the taxonomy field):
using (SPSite site = new SPSite("http://myUrl"))
{
using (SPWeb web = site.OpenWeb())
{
string tagsFieldName = "Tags";
string myListName = "MyList";
string myTermName = "myTerm";
SPListItem myItem = web.Lists[myListName].GetItemById(1);
TaxonomyField tagsField = (TaxonomyField) myList.Fields[tagsFieldName];
TaxonomySession session = new TaxonomySession(site);
TermStore termStore = session.TermStores[tagsField.SspId];
TermSet termSet = termStore.GetTermSet(tagsField.TermSetId);
Term myTerm = null;
try
{
myTerm = termSet.Terms[myTermName];
}
catch (ArgumentOutOfRangeException)
{
// ?
}
string termString = String.Concat(myTerm.GetDefaultLabel(1033),
TaxonomyField.TaxonomyGuidLabelDelimiter, myTerm.Id);
if (tagsField.AllowMultipleValues)
{
TaxonomyFieldValueCollection tagsValues = new TaxonomyFieldValueCollection(tagsField);
tagsValues.PopulateFromLabelGuidPairs(
String.Join(TaxonomyField.TaxonomyMultipleTermDelimiter.ToString(),
new[] { termString }));
myItem[tagsFieldName] = tagsValues;
}
else
{
TaxonomyFieldValue tagValue = new TaxonomyFieldValue(termString);
myItem[tagsFieldName] = tagValue;
}
myItem.Update();
}
}
