Hello,

We are getting an intermitent java script error in our SharePoint custom ASP.NET page. (FYI, the telerik controls are showed into page via web parts which intern calls .NET user control)

Java script error details:

Message: 'type' is null or not an object
Line: 6
Char: 33796
Code: 0
URI: http://mycompany.com/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d3.5.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3ad0c4ca6e-6b5d-49b6-922d-5244924fb100%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2012.1.411.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3a4cad056e-160b-4b85-8751-cc8693e9bcd0%3a16e4e7cd%3aed16cbdc%3a86526ba7%3af7645509%3a2003d0b8%3a24ee1bba%3ae330518b%3a1e771326%3ac8618e41%3af46195d3%3aaa288e2d

We make use of lastest Telerik.Web.UI and Telerik.Web.UI.Skins dlls version 2012.1.411.35.

Below are the list of web.config changes made for Telerik usage,
1) SafeControl
 
2) Page tag prefix

3) web.server handlers

The page works fine most of the time; but at times it throws above specified java script error and dont work anymore until another page refresh.

I couldn't even debug this error as this is very unstable error.  
May I know what may be the issue?

Your reply is much appreciated.

Thanks,

Hi,

I need to implement the recursive selection at this way:
1. Select all parents when the at least one child item was selected.
2. Select all childs when the parent was selected.

When i use "AllowRecursiveSelection=true" the 1st part of the task does not work for me (when deselect one of the child - parent deselects too). If AllowRecursiveSelection is true then "OnItemSelected" and "OnItemDeselected" client events does not fire...
In other way at client side "get_childItems()" return null for the node not expanded before select and "ExpandCollapse" command fires after "OnItemSelected" and "OnItemDeselected"...

I have no idea how to implement this task. Can anybody show the right way to complete this?

Thx.

Greetings,

I have a problem with recursive selection. Treelist selects recursively whole branch of selected node (all its ancestors and descendants). This behavior is pretty "unconfortable" for me. If my nodes are folders and files and I select a subfolder and I want to delete it with it contents for example then I cerainly don't want to delete its parent folder (or any of its ancestors) so I would like to ask if there is any way how to make treelist to recursively select only descendant nodes of selected item.

Thanks in advance

I have the following JavaScript code that creates a really simple JSON object...


This generates the following JSON string after running the object through the stringify method...

{"MyID":1,"MyItem":"This is the first item"}

This is valid JSON according to JSONLint.com.
Calling the .ajaxRequest() method results in Sys.WebForms.PageRequestManagerServerErrorException - "Specified cast is not valid"

It's not even getting to my RadAjaxManager1_AjaxRequest() event handler where I have a breakpoint set to inspect the value of e.argument.

What's wrong here?

I'm using version 2010.3.1317.35 of the Telerik controls.

I have an usercontrol that has a RadTabStrip control. This usercontrol is loaded in SharePoint 2007. The problem is that the Tabclick event is working for IE, Chrome, and Firefox but not for Safari.

I have a Breakpoint in the RadTabStrip1_TabClick event and I found out that code never is running.

I need your help!!
Safari 5.1.7
SharePotin 2007
Telerik 3.5

Hello,

I am new at Telerik RadGrid in Ajax/ASP .NET.

I am trying to allow the user of my application to be able to re order the columns of my RadGrid. I found on your website that :

GridDragDropColumn  has to be inserted in the Columns collection of a GridTableView, But as my RadGrid columns are autogenerated, I have no <Column> tag in the description of my RadGrid. So I am trying to understand where should the GridDragDropColumn  tag be inserted to allow Columns drag and drop (and re-ordering).
I tried to insert it in the <Columns> description of my MasterTableView (see the code below) but when running it, I cannot drag any of my columns ?

Another point is that I want that my columns can also be sorted by one click on the header of the column. Is that compatible with the GridDragDropColumn  option ?

Thank your for your help.

Here is the code of my grid in my ASPX file :

am using telerik tab strip control in page2.aspx...am calling this page frompage1.aspx.... from there itself i want to mention the tab which i want to see first.in page1.aspx i have equal no of menu for each tab. for ex, if i click on 3rd menu then it shd redirect to page2.aspx and it shd focus on 3rd tab....

Hi,

How can I change the background image of RibbonBar?

Thanks in advance

Hello,

I'm encountering an exception using RadGrid's NestedViewTemplate feature.
If I set HierarchyDefaultExpanded="true" RadGrid, NestedViewTemplate is rendering correctly but all rows are expanded which is not very interesting. So i leave HierarchyDefaultExpanded to false so rows are initially collapsed when i expand a row following exception is raised

 
I have tested a lot of scenarios with no success. RadGrids are both initialized programmatically (ItemCommand, ItemCreated, PreRender, NeedDataSource for NHibernate list).

After testing, exception raise when system tries to render manual columns (GridDateTimeColumn, GridBoundColumn) as  AutoGenerateColumns="False". If i remove manual columns, expand/collapse is working.

Hi, we're using the FormDecorator and I notice on the front end the dropdownlist renders as a div with spans instead of a traditional html select list.

When I try to use jquery to set the selected value after the control renders it doesn't change. I'm guessing because this is technically not a select list anymore.

Is there any work around to this?
