Heely Guys

Story: I have a strange error when I try to save something I got this error message ( An entity object cannot be referenced by multiple instances of IEntityChangeTracker.)
I really don’t know what that is and why is it appear, it appears only when I try to save something my insert and update is working, only when I try to save something in db from my grid

After debugging I have seen that the code brake down in the Project.Name.Designer.cs ..... O.o

I'm stepping through my ASP.NET app (I didn't build it, but I'm supporting it), and all of the many references to things like RadCheckBox or RadControl seem to work perfectly well.

At the end I get an error in a very, very long script that Telerik seems to emit. There is an error in the middle of it, 'ID' variable cannot be found. It highlights 'e.detachEvents' every time, and a variable named 'ID' is nowhere close.

Any clue how I might side step this error? I hit continue and the app proceeds. And the error does not appear after deploying to the test server.

Thanks, Bob Sullentrup

Hello.  I inherited an asp.net application that uses Telerik.Web.UI.
On this one particular page it uses asp:DropDownList that works in older browsers (i.e. Firefox 14), but the DDL would not expand in current version of Firefox, Chrome, IE.  Has anyone encountered this problem yet?
Any help is greatly appreciated.

Hi,

I need to build a photograph competition page that has a RadTabStrip which I add tabs to for each competition. Each tab contains a user control, that has a RadListView to view the member's entries and two buttons, for uploading and deleting entries.

I am having difficulty with the ItemDataBound & NeedDataSource events in the RadListView. I am not sure what to do and would appreciate it if someone could steer me in the right direction.

Kind regards,
Pierre

Hi,

 

I am  facing an issue with our application, the checkbox inside the Telerik  Radgrid in our application is not unchecking when it is clicked first time (as per the business logic the  grid will be loaded as few rows checked. And this issue occurring only in this scenario).  But it is unchecking on the second time clicked.  This issue we got after migrating the  application from .Net 3.5 to 4.0.

In our 3.5 application  grid is working fine in the above said scenario. we have  tried with  4.0 Telerik and Spring DLL ‘s, still we are facing the same issue.

 

Please suggest us on what we can do  to rectify the Telerik Control issue.

Hello,

I used the following code to generate items inside a RadComboBox



My problem is it seems that any items inside the <ItemTemplate> tag does not inherit or use the css styles defined on RadComboBox's Skin attribute. The items are generated but there's no background color changes (onmouseover) on the items.

is there a way for the items to be able to use the defined skin?

Thanks

Hi there I have a list box filled with a list of course names. If a course is assigned to you then it will have a green colour block before the name, if its not assigned to you it will appear with a red block before the name. I have three radio buttons one called "All", another called "Assigned", and the last one called "Not Assigned". Is it possible when selecting assigned that the green ones will just appear and when selecting not assigned only the red ones will appear? I've tried adding the radio button code into the page load but editing the lists like this removes the items forever for example when I click on assigned it removed the red items for the remainder of that session. What is the best way to do this?

Thanks, James

I just installed the Tererik Controls to visual studio and when I added the RagOrgChart to my page it added just fine but when I opened it up in my browser it gave me a security warning:  Her is the HTML Code:

Hi,

I downloaded the telerik suite of controls from the below location: RadControls for ASP.NET AJAX Q3 2012
 http://www.telerik.com/products/aspnet-ajax/download.aspx

I have checked this site: http://www.telerik.com/help/aspnet-ajax/moss-deploying-radcontrols.html

I am using SharePoint 2010 and trying to use the RAD Grid. I created a visual web part and added the radgrid and bound the controls.
I have the Telerik.web.ui (version 2012.3.1016.35), Telerik.Web.Design (version 2012.3.1016.35) in GAC. I have added the safecontrols as below:

I have both the dll's added in 14 bin and in the  bin of the website.
I am getting the error as "could not load file or assembly Telerik.web.ui Version 2011.2.712.20,culture=neutral,PublicKeyToken=121fae78165ba3d4 . The located assembly's manifest location does not match the assembly reference.

How to fix this?
Thanks
