Hi All,

I have RadGrid with datas which works fine.

I added a new button for delete.

While deleting I get a java script error.

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Unable to cast object of type 'Telerik.Web.UI.GridCommandItem' to type 'Telerik.Web.UI.GridEditableItem'.

}

Is there any option to solve this.

Have even attached the screen shot.

Thanking You

Hello Anto,

The problem is that you are trying to use automatic operation for the grid, when you have custom buttons that perform those operations. Automatic operations are only allowed when we have declarative databinding in the grid, using the DateSourceID property of the control. For more information see the following article.

To fix the problem you have to disable AutomaticUpdates, Inserts and Deletes and handle those operations manually in code behind (e.g. OnItemCommand).
<MasterTableView  AllowAutomaticInserts="false" AllowAutomaticUpdates="false" AllowAutomaticDeletes="false">
For more information you may refer to the following articles:
http://www.telerik.com/help/aspnet-ajax/grdinsertupdatedeleteatdatabaselevel.html
http://www.telerik.com/help/aspnet-ajax/grdhowtodeletearecord.html

Hi, I have a similar problem and have search the forums but haven't been able to resolve this issue.   I am getting a JScript runtime error ONLY when there is no data. This is the version I'm using

2010.3.1109.40.  and this site said that there are no updates .
Any help is appreciated.

Thanks

Hi Rose,

The issue seems to be related with the ActiveRowIndex property of the client settings for the grid:
<ClientSettings ActiveRowIndex="0"

If you remove it, the error should not be thrown. Also, note that this issue has been addressed in the latest internal build available on the web site.
