I have an editable text web part on a page template. It has a custom HTML envelope before and after the text. How can I hide the whole thing, envelope included, if the editable text is empty?
I need to hide it because the envelope adds stylized markup that shouldn't be visible when there is no text.
Can it be done with a K# snippet on the Visible property? I'm unclear how interrogating a document's property works.
Thanks!
Try this as the "Visible" property:
{% (ViewMode != "LiveSite") || (CMSContext.CurrentDocument.editabletext != "") #%}
Change "editabletext" to whatever you have for your web part control ID.
I'm not familiar with Kentico but these solutions might help. They may not address your problem specifically but might aid in a solution.
CMSEditableImage Extension Method
I came up with a way to check this, I added an extension method for
the CMSEditableImage class that takes the CurrentPage PageInfo object
to check the value of the editable region, don't know if this is the
best way or not, but here's the code.
public static bool IsPopulated(this CMSEditableImage editableImage, PageInfo currentPage)
{
bool isPopulated = false;
string value = currentPage.EditableItems.EditableRegions[editableImage.ID.ToLower()].ToString();
if (!string.IsNullOrEmpty(value))
{
value = value.ToUpper();
isPopulated = (value == "<IMAGE><PROPERTY NAME=\"IMAGEPATH\"></PROPERTY></IMAGE>") ? false : true;
}
return isPopulated;
}

JavaScript Method
The webcontainer needs an id, example:
<h2 id="webpart-header">Headline</h2>
Then I have a small javascript function that is attached in an
external js file:
/* Hide Webcontainer via javascript if empty*/
function hideLayer(element) {
elem = document.getElementById( element );
elem.style.display = "none";
}
Now in the wep part configuration, at no data behaviour, you uncheck the checkbox and call the js function by entering following
script in the no record found text: hideLayer("webpart-header");
Whereby webpart-header the id name of your container is. You could
also have a more complex <div> structure here.

I searched the whole web and I couldn't found any good topic which expose the proper way to do it.
I have a very simple web which I developed using Kentico 9 CMS. This web only contains two subpages and a header to navigate between those.
The "Home" subpage contains a custom form which remains connected to a SQL table which is populated every time you press submit with certain data.
On the other hand, the other page, shows the stored data by using a custom web part which connects to the DB by using BizFormItemProvider and this object is used as a layer to binding the data in a control.
Now is my point. If you see, there is a button to "Edit" a certain row and my intention is to Redirect to "Home" (which contains the form) and sending via QueryString the ID of the row attempted to edit.
I was unable to understand how can you re-fill the form with its data using an ID.
Maybe because I never worked with a CMS before, I'm looking the development such as pure ASP.NET and it could not be the correct one.
Custom
Given that your solution uses a custom form for entering the data, as well as a custom web part for listing the stored data, you will need to use a custom solution to handle the editing of data, as well.
In the custom webpart on the Home page, in a load event, you can retrieve the form data and set the values on the form controls.
protected void Page_Load(object sender, EventArgs e)
{
// Ensure that the form is not being posted back,
// to prevent entered data from being overwritten
if(!IsPostBack)
{
// Get the form item ID from the query string
var personId = QueryHelper.GetInteger("personId", 0);
if(personId > 0)
{
// Get the biz form item, and set form control values
var bizFormItem = BizFormItemProvider.GetItem(personId, "customFormClassName");
txtFirstName.Text = bizFormItem.GetStringValue("FirstName", string.Empty);
}
}
}
Similarly, when Submit is clicked, you can update the existing form item with the new data
protected void btnSubmit_OnClick(object sender, EventArgs e)
{
// Get the form item ID from the query string
var personId = QueryHelper.GetInteger("personId", 0);
if(personId > 0)
{
// Retrieve the existing biz form item,
// and update it from the form control values
var bizFormItem = BizFormItemProvider.GetItem(personId, "customFormClassName");
bizFormItem.SetValue("FirstName", txtFirstName.Text);
bizFormItem.Update();
}
else
{
// Your code for inserting a new form item...
}
}
The Kentico way
You should really consider using the Kentico form engine for accomplishing this task. Instead of using a custom form for entering the data, use the built-in On-line form webpart.
The benefits are numerous, such as:
Ability to set the form layout through the CMS, and use alternative layouts
Automatic confirmation email to the submitter of the form, as well as notification emails to the administrators
To accomplish your task, you can customise the On-line form webpart to support loading of existing data.
In the bizform.ascx.cs file, add code to the SetupControl method:
protected void SetupControl()
{
if (StopProcessing)
{
// Existing code...
}
else
{
// Existing code...
// Get the form item ID from the query string
var personId = QueryHelper.GetInteger("personId", 0);
if(personId > 0)
{
// Get the biz form item, and set form control values
var bizFormItem = BizFormItemProvider.GetItem(personId, "customFormClassName");
if(bizFormItem != null)
{
// Set the item ID
viewBiz.ItemID = bizFormItem.ItemID;
}
}
}
}
This will automagically switch the form to Edit mode, instead of Insert mode, as soon as you set the ItemID property. Clicking the Submit button will save changes on the existing form item.
You will not need to worry about validation in your code, and inserting data will still work.
Is this a contact form that you are using Kenticos built in form application for, or is it a custom form? If it is a custom form you can create a transformation with a link that will contain the ID. If it is a biz form, you can still create a transformation in Page Types (create a new page type and select "The page type is only a container without custom fields"), then write a custom query to get the biz form data, and use a repeater to display the data with that transformation.
Good day!
In my Orchard, I have several content types all with my custom part attached. This part defines to what users this content is available. For each logged user there is external service, which defines what content user can or cannot access. Now I need access restriction to apply everywhere where orchard display content lists, this includes results by specific tag from a tag cloud, or results listed from Taxonomy term. I seems can’t find any good way to do it except modifying TaxonomyServices code as well as TagCloud services, to join also my part and filter by it. Is this indeed the only way to do it or there are other solutions? I would like to avoid doing changes to built-in modules if possible but cannot find other way.
Thanks in advance.
I'm currently bumbling around with the same issue. One way I'm currently looking at is to hook into the content manager.
[OrchardSuppressDependency("Orchard.ContentManagement.DefaultContentManager")]
public class ModContentManager : DefaultContentManager, IContentManager
{
//private readonly Lazy<IShapeFactory> _shapeFactory;
private readonly IModAuthContext _modAuthContext;
public ModContentManager(IComponentContext context,
IRepository<ContentTypeRecord> contentTypeRepository,
IRepository<ContentItemRecord> contentItemRepository,
IRepository<ContentItemVersionRecord> contentItemVersionRepository,
IContentDefinitionManager contentDefinitionManager,
ICacheManager cacheManager,
Func<IContentManagerSession> contentManagerSession,
Lazy<IContentDisplay> contentDisplay,
Lazy<ISessionLocator> sessionLocator,
Lazy<IEnumerable<IContentHandler>> handlers,
Lazy<IEnumerable<IIdentityResolverSelector>> identityResolverSelectors,
Lazy<IEnumerable<ISqlStatementProvider>> sqlStatementProviders,
ShellSettings shellSettings,
ISignals signals,
//Lazy<IShapeFactory> shapeFactory,
IModAuthContext modAuthContext)
: base(context,
contentTypeRepository,
contentItemRepository,
contentItemVersionRepository,
contentDefinitionManager,
cacheManager,
contentManagerSession,
contentDisplay,
sessionLocator,
handlers,
identityResolverSelectors,
sqlStatementProviders,
shellSettings,
signals) {
//_shapeFactory = shapeFactory;
_modAuthContext = modAuthContext;
}
public new dynamic BuildDisplay(IContent content, string displayType = "", string groupId = "") {
// So you could do something like...
// var myPart = content.As<MyAuthoPart>();
// if(!myPart.IsUserAuthorized)...
// then display something else or display nothing (I think returning null works for this but
//don't quote me on that. Can always return a random empty shape)
// else return base.BuildDisplay(content, displayType, groupId);
// ever want to display a shape based on the name...
//dynamic shapes = _shapeFactory.Value;
}
}
}
Could also hook into the IAuthorizationServiceEventHandler, which is activated before in the main ItemController and do a check to see if you are rendering a projection or taxonomy list set a value to tell your content manager to perform checks else just let them through. Might help :)
We Have Contact Entities in contact Entitie one lookup filed company Name in that lookup having two values 1.Account and 2.Contact . When we are selecting contact show the address filed when we select account hide the address filed we needs to write the plugin to Execute that works. Kindly any one help me on the same.
Thanks!!

First, if you need to make change on a form, you can't use plug-ins. Plug-ins are made for bussinees logics, like Update another record when the first one is created, make complex logic, etc...
What you need it is a javascript that executes on the OnLoad of the form and OnChange event in that OptionSet.
The lines you are looking for are:
function ShowField()
{
// The field is present on the form so we can access to its methods
var optionSet = Xrm.Page.getAttribute("custom_attribute");
if (optionSet == undefined)
{
return;
}
// The control is present on the form so we can access to its methods
var controlAddress = Xrm.Page.getControl("custom_address");
if (controlAddress == undefined)
{
return;
}
var valueOptionSet = optionSet.getValue(); // This is the value you set creating the OptionSet
switch (valueOptionSet)
{
case 0: // Your account value, show
controlAddress.setVisible(true);
case 1: // Your contact value, hide
controlAddress.setVisible(false);
default:
return;
}
}
You need to register a web resource and register the event, if you need more information about the code or why this stuff is here and why this not just tell me.
Using the admin panel on Orchard CMS I've created the following:
A content type called CalendarEvent, it contains several fields including the EventDate;
A query that has 2 filters, one by the content type (= CalendarEvent) and another one based on the date of the event. The Display Mode on the Layout is set to Properties;
A projection to display the query when a menu item is clicked.
The problem is that based on the EventDate we only display upcoming events, not the ones in the past. If for some reason there are no events to be displayed, all the user gets is an empty page with no information whatsoever.
My question is, how can I modify my query or projection in order to display something like: "There are no current events scheduled"?
I know the Properties on the Query's Layout allow me to specify a "No Result", but this implies that a record is present and that the actual property is empty. However, in my example, no record is present.
Thank you all in advance.

By the way, I am using the latest Orchard version 1.6.
What I have done is to create a shape and use it as a view in my query. The shape will then have an if statement to check if the query return gives any results.
Example:
#using Orchard.ContentManagement
#using Orchard.Utility.Extensions
#{
var dealsTerms = ((IEnumerable<ContentItem>)Model.ContentItems).ToList();
}
#if (dealsTerms.Any() )
{
<div>
#foreach (var dealTerm in dealsTerms)
{
var contentManager = dealTerm.ContentManager;
<div>
#Display(contentManager.BuildDisplay(dealTerm, "Summary"))
</div>
}
</div>
}
else
{
<p>No deals found</p>
}
I used this article as reference:
http://www.ideliverable.com/blog/ways-to-render-lists-of-things
Good luck
If your projections are Layouts elements, you can create a Projection.cshtml file in your theme's Views/Elements folder with the following:
#{
var list = Model.List;
var pager = Model.Pager;
if (list != null)
{
#Display(list)
if (list.Items.Count == 0)
{
<div>There are currently no items.</div>
}
}
if (pager != null)
{
#Display(pager)
}
}
This is a copy of the default template with the if (list.Items.Count == 0) section added. Edit as needed.
I'm trying to hide the "Title" field in a list.
This doesn't seem to work:
SPList myList;
...
SPField titleField = myList.Fields.GetField("Title");
//titleField.PushChangesToLists = true; <-- doesn't seem to make a difference
titleField.ShowInEditForm = false;
titleField.ShowInDisplayForm = false;
titleField.ShowInNewForm = false;
titleField.Update();
//myList.Update(); <-- make no difference
What am I doing wrong?
Try this:
field.Hidden = true;
field.Update();
None of the above examples of setting Hidden true will work unless CanToggleHidden has a value of true. The problem is, CanToggleHidden only has a Get, not a Set, so you have to perform a radical "SharePoint programming gymnastics stunt" using reflection to first flip CanToggleHidden from false to true. Once you have done that, you can change Hidden to true (or back to false). There are plenty of examples out on the web (although not all of them are written correctly). If needed, I can probably dig up a PowerShell example that works.
if(field.CanToggleHidden) {
field.Hidden = false;
}
else
{
// display an error message or write to your favorite logging location
// explaining that there is no hope of changing the value of Hidden until
// CanToggleHidden changes to TRUE first.
}
Make sure you are grabbing a new SPWeb instance.
using (SPSite site = new SPSite(webUrl))
{
using (SPWeb web = site.OpenWeb())
{
try
{
//... Get SPList ...
}
}
}
I believe visibility of fields in lists are controlled by the default view that the user "gets". Don't you want to modify the view? I know you can get the Views for a list, as well as the default view.
I'm just spit-balling here...
There is a price you pay when you use Hidden property.
It's been discovered that setting a column hidden will remove the ability to delete it via code.
try this one this will work...
Title field is named as LinkTitle...
other fields can be hidden in the same way.
SPView view = list.DefaultView;
if(view.ViewFields.Exists("LinkTitle"))
{
view.ViewFields.Delete("LinkTitle");
view.Update();
}
The solution above is for hiding the field everywhere. It will also be hidden in the column overview of your list.
If you only want to hide the field in a particular list. Or if you still to manipulate the field (set back to visible) by using the list settings page. You need to set the "Hidden" property of the field in the "FieldLinks" property of the list.
myList.FieldLinks["SomeField"].Hidden = true;
