I faced such a problem and how I can not overcome:
PXView does not contain a definition for Select and the best extension method overload EnumerableEx.Select<T>(IEnumerable)
My goal is to pass different views to the method, for example, I did it this way and it works with a specific type and a specific view.
var grid = Transaction.Select<TSITransaction>().ToList();
But the problem is that I don't know which view is coming to me
public void ValidationTabInformation<T, K, U>(string viewName, PXView viewQuery, PXView viewQueryCache, PXView cascadindView, PXView enablingConditions)
where T: TSNTagQueries
where K: TSNWCascade
where U: TSNTransConditions
{
var grid = viewQuery.SingleToArray().Select<T>().ToList();
var cascading = cascadindView.SingleToArray().Select<K>().ToList();
var deleted = viewQueryCache.Cache.Deleted.RowCast<T>().ToList();
var conditions = enablingConditions.SingleToArray().Select<U>().ToList();
var isRequired = string.Empty;
//... doing something
}
protected void DataFieldValidation()
{
//ValidationAsset();
//ValidationEmployee();
//ValidationTransaction();
//ValidationLinkInfo();
ValidationTabInformation<TSNAsset, TSNCascadeAsset, TSNAssetConditions>(Asset.Name, Asset.View, Asset.View,CascadingAsset.View, TagAssetEnablingConditions.View);
}
Exception:

Try something like this
var grid = viewQuery.SelectMultiBound(new object[] {T});

Is it possible to use a foreach loop in a BLC to iterate through the fields of a PXResultSet to get the FieldNames?
Is this doable? I can't seem to find a good way.
Thanks...
The PXResultset records are selected from a view. You can get the field names from the View.
Here's a full example:
public class SOOrderEntry_Extension : PXGraphExtension<SOOrderEntry>
{
public override void Initialize()
{
// Get field list from data view
var dataView = new PXSelect<SOOrder>(Base);
string fieldNames = string.Join(",", GetFieldNames(dataView.View, Base.Caches));
// You don't need result set to get field names
PXResultset<SOOrder> resultSet = dataView.Select();
throw new PXException(fieldNames);
}
public string[] GetFieldNames(PXView view, PXCacheCollection caches)
{
var list = new List<string>();
var set = new HashSet<string>();
foreach (Type t in view.GetItemTypes())
{
if (list.Count == 0)
{
list.AddRange(caches[t].Fields);
set.AddRange(list);
}
else
{
foreach (string field in caches[t].Fields)
{
string s = String.Format("{0}__{1}", t.Name, field);
if (set.Add(s))
{
list.Add(s);
}
}
}
}
return list.ToArray();
}
}
When run, this example will show the fields names used in the data view in Sales Order screen SO301000 as an exception.
Field names are contained in Cache object. If you really need to get field names from PXResultset you need to iterate the cache types in the result set.
Example for first DacType (0) of result set:
public class SOOrderEntry_Extension : PXGraphExtension<SOOrderEntry>
{
public override void Initialize()
{
var dataView = new PXSelect<SOOrder>(Base);
PXResultset<SOOrder> resultSet = dataView.Select();
foreach (PXResult result in resultSet)
{
Type dacType = result.GetItemType(0);
foreach (var field in Base.Caches[dacType].Fields)
PXTrace.WriteInformation(field);
}
}
}
thank you for your reply,
i added BeginExecuteCore in base controller like this
`public class BaseController : Controller
{
protected override IAsyncResult BeginExecuteCore(AsyncCallback callback, object state)
{
//string email = string.Empty;
dbEntities dbcontext = new dbEntities();
var userRoleName = (from n in dbcontext.VAgentClientEmails where n.Email == User.Identity.Name select n.Role).FirstOrDefault();
if (userRoleName == "SuperAdmin")
RouteData.Values["role"] = userRoleName;
else
RouteData.Values["role"] = "";
return base.BeginExecuteCore(callback, state);
}`
and i have given in home controller like this
[Route("~/{role}/SavedSearch/Index")]
public ActionResult Index()
{
...
}
its working for admin/savedsearch/index
and also if i give fjsdfk/savedsearch/index its working
in the above case it should not work..
and in else case i dont want role
do i need to do any changes?
My question is related to this one, but instead of changing a question I thought it Would be better to ask a new one.
I've now got a list of IContent items using the _taxonomyService.GetContentItems(term)
as suggested by #Bertrand Le Roy in the question mentioned above
But how do I turn this into a useful Html string, that I can update on the client via an ajax post?
public class HomeController : Controller
{
private readonly IOrchardServices _services;
private readonly IBlogService _blogService;
private readonly IBlogPostService _blogPostService;
private readonly IFeedManager _feedManager;
private readonly IArchiveConstraint _archiveConstraint;
private readonly ITaxonomyService _taxonomyService;
public HomeController(
IOrchardServices services,
IBlogService blogService,
IBlogPostService blogPostService,
IFeedManager feedManager,
IShapeFactory shapeFactory,
IArchiveConstraint archiveConstraint,
ITaxonomyService taxonomyService) {
_services = services;
_blogService = blogService;
_blogPostService = blogPostService;
_feedManager = feedManager;
_archiveConstraint = archiveConstraint;
T = NullLocalizer.Instance;
Shape = shapeFactory;
_taxonomyService = taxonomyService;
}
dynamic Shape { get; set; }
public Localizer T { get; set; }
public ActionResult Index()
{
return View();
}
[HttpPost]
public JsonResult ListByArchive(string path, IEnumerable<string> category)
{
try
{
// get year and month from path
path = path.ToLower().Substring(path.LastIndexOf(#"/archive/", StringComparison.Ordinal) + 9);
var date = path.Split('/');
var month = int.Parse(date[1]);
var year = int.Parse(date[0]);
// get list of terms ids from strings
var taxonomyPart = _taxonomyService.GetTaxonomyByName("Category");
var terms = category.Select(cat => _taxonomyService.GetTermByName(taxonomyPart.Id, cat)).ToList();
// get list of content items by term avoiding duplicates
var posts = new List<IContent>();
foreach (var term in terms)
{
var items = _taxonomyService.GetContentItems(term);
foreach (var item in items)
{
if (!posts.Select(p => p.Id).Contains(item.Id))
{
posts.Add(item);
}
}
}
// filter by date
var byDate = posts.Where(x =>
{
var publishedUtc = x.ContentItem.As<CommonPart>().CreatedUtc;
return
publishedUtc != null
&& publishedUtc.Value.Month == month
&& publishedUtc.Value.Year == year;
});
....
This gets me my list of IContent, but how do I get a the html for the rendered list ?
I've tried
var range = byDate.Select(x => _services.ContentManager.BuildDisplay(x, "Summary"));
var list = Shape.List();
list.AddRange(range);
dynamic viewModel = Shape.ViewModel().ContentItems(list);
var html = View((object)viewModel);
return Json(new { html = html });
but it returns an empty view,
{"html":{"MasterName":"","Model":[],"TempData":[],"View":null,"ViewBag":{},"ViewData":[],"ViewEngineCollection":[{"HostContainer":{}}],"ViewName":""}}
I have a view called ListByArchive.cshtml, that matches the one it the orchard.blog module.
As an aside, I should be returning a partial view result, instead of a jason result, but when I change the Action result type I get a 404. result from the server.
This is never going to work the way you think it does:
var html = View((object)viewModel);
The easiest way to return HTML representing the content item is to:
Mark your action with ThemedAttribute, ie. [Themed(false)]
Return new ShapeResult(this, viewModel) (full view) or new ShapePartialResult(this, viewModel) (partial view) instead of Json(new { html = html })
Rendering a shape/view to string inside the action is also possible, but way more tricky.
EDIT: I assumed you already have /Views/ViewModel.cshtml file in place. Like Bertrand Le Roy noted below - if it's not there, you need to add one to be able to create a shape using Shape.ViewModel().
We have a Sharepoint site which uses search.
We get the following error:
Unable to validate data. at
System.Web.Configuration.MachineKeySection.EncryptOrDecryptData
(Boolean fEncrypt, Byte[] buf, Byte[] modifier, Int32 start, Int32 length,
IVType ivType, Boolean useValidationSymAlgo)
at System.Web.UI.ObjectStateFormatter.Deserialize(String inputString)
After a bit of testing we have found that the error occurs when we use DateKeyNames on a GridView control.
Not sure why there should be any combination between Search, this error and DataKeyNames.
Any ideas?
Update: Here is some code
[Guid("8891224e-e830-4ffa-afbd-f789583d8d14")]
public class TestErrorGridView : System.Web.UI.WebControls.WebParts.WebPart
{
Control ascxToAdd;
public TestErrorGridView()
{
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}
protected override void CreateChildControls()
{
base.CreateChildControls();
Table test = new Table();
TestBindObject t1 = new TestBindObject() { ID = 1, Name = "Test" };
List<TestBindObject> l1 = new List<TestBindObject>();
l1.Add(t1);
SPGridView testGrid = new SPGridView() { AutoGenerateColumns = false};
BoundField header = new BoundField();
header.DataField = "ID";
BoundField name = new BoundField();
name.DataField = "Name";
testGrid.Columns.Add(header);
testGrid.Columns.Add(name);
testGrid.DataSource = l1;
testGrid.DataBind();
// If you comment out this line search works
testGrid.DataKeyNames = new string[] { "ID" };
this.Controls.Add(testGrid);
base.CreateChildControls();
SPGridView testGrid = new SPGridView() { AutoGenerateColumns = false, EnableViewState=false };
testGrid.DataKeyNames = new string[] { "testid" };
this.Controls.Add(testGrid);
}
}
public class TestBindObject
{
public int ID { get; set; }
public string Name { get; set; }
}
UPDATE
This error occurrs on the developer machines, so it is not realated to machine keys being different on different machines in a cluster.
One of the developers has MOSS installed, he does not get the error. The developers who have just WSS installed get the error.
UPDATE 2
Have added datasource to code
I'm going to throw out a guess here since the code where you set the GridView's datasource is missing as well, but here goes...
It probably has something to do with the order in which you are setting the GridView's properties. My guess is that you need to set it in this order:
Create your GridView
Set the GridView's datasource (so that it has data)
Set DataKeyNames
Call GridView.DataBind()
Step 3 and 4 are the steps I am not sure about. You may have to DataBind and then set DataKeyNames.
We eventually solved this by following the example in this link:
http://msdn.microsoft.com/en-us/library/bb466219.aspx
I think that is was binding to a data table rather than a list that made the difference.
The fact that Sharepoint grids do not allow autogenerated columns appears to be one of the factors leading to this problem.
I have a baseclass that handles returning data from the relevant class/table.
I want to have some way of specifying the columns to display. Maybe have a public columns List that gets assigned with all column we want to display?
This is what I have but its not right.
public void SetupGrid<T>() where T : class, new()
{
var db = new MyApp.MyDB();
IRepository<T> repo = new SubSonicRepository<T>(db);
var s = repo.GetAll();
var x = from c in s select new { c.Columns //that match columns I specify };
}
This seems to do it, however unsure if its best practice:
public virtual void SetupGrid<T>() where T : class, new()
{
MyApp.MyDBdb = new MyApp.MyDB();
IRepository<T> repo = new SubSonicRepository<T>(db);
ITable table = repo.GetTable();
List<string> list = new List<string>();
list.Add("CreatedOn");
list.Add("PageID");
list.Add("CreatedBy");
var s = db.SelectColumns(list.ToArray()).
From(table.Name).
OrderAsc(table.Descriptor.Name).ExecuteReader();
bindingSource1.DataSource = s;
}
