Hello everyone and special thanks to Princy!

I am using a Radgrid with a Radwindow on Editing , you can see all about it in “Demo/Asp.Net Ajax/Window/Edit Dialog For RadGrid”

I tried it to customize it in my Project logic and every thing is fine when I use the same structure(DefaultCS.aspx, and code behind and EditForm and its codebehind).

But I am using a UserControl instead of aspx file ,as follow :

Root

Folder :Usercontrols

ChargePanel.ascx(Instead of DefaultCS.aspx)[Inherited from SiteMasterpage]

EditForm.aspx

SiteMasterPage.master

When I click On Edit Button everything is true still, and works fine ,and the Grid will be updated after closing windows with some Java Script Code,after do that if I tend to edit another row when I click the Edit button It will raise an error!

Microsoft JScript runtime error: 'null' is null or not an object

Here is my Code,I have tried to find a solution from Many posts but I didn’t find anything to help me…

Hello Bahram,

I was not able to get this error (and anyway, it is too generic for me to be able to tell its origin), yet there were other errors raised from your code, mostly due to the way you add AJAX to the page.

In the case of user controls and master pages it is recommended that you place the RadAjaxManager in the master page and use either programmatic AjaxSettings, or a RadAjaxManagerProxy. This approach is described in the following online resources:
http://www.telerik.com/help/aspnet-ajax/ajax-masterpage.html
http://demos.telerik.com/aspnet-ajax/ajax/examples/manager/usercontrol/defaultcs.aspx

This prompts for a change in the way you reference the controls as well, and you can find an example for this in my sample project that I have attached. Please examine it and compare it with your actual project, as it seems to be working correctly on my end and no errors are thrown. Please also note my comments in the code.

Feel free to use my sample as basis for your development and extend it further as needed by your custom logic.

On a side note - I would advise that you examine this help article on some better ways to inject the script that closes the RadWIndow.

All the best,

Hi
I tried implementing a simple EditMode=PopUp in a RadGrid control that is within a Usercontrol and it does not seem to work . Where as if the same control id used directly on the Page , the edit popup shows up. Can you please guide me as to what needs to be done when using the rad control within the usercontrol. Attached is a code for reference.

Thanks in advance

Hello L D,

Please try removing the ClientIDMode property, as the RadControls do not support the scenario where it is set to Static. This is because most of them are complex container controls and thus require the id changes the framework does for any other INaming container, while setting ClientIDMode to Static disables this.

Kind regards,
