I am just getting started with using the win forms controls rad grid view. I am using linq DataContext class as the basis of my binding source. This loads the rad grid fine but when i select a row i come up with this error. "This row has been removed from a table and does not have any data.  BeginEdit() will allow creation of new data in this row." This shows up in the Applicationrun in my Program.cs file. I was using the standard win forms controls and have no problem with selecting rows. I have looked at the online help but have only seen a couple of instances that i thought would work but nothing yet has proven true. Any ideas as to what properties or actions i need to take.

Thanks john.

Thanks for your reply to my question. My problem is solved with just adding a simple line of code. I needed to assign my variable used in my linq query for my binding source to the actual grid instead of just to my binding source. Thanks again for your reply.

Hello Jack,

I am facing the same problems as John. I did not really understand the solution mentioned in this thread.

Problem: Everytime I click on the Telerik Grid I see this exception (This row has been removed from a table and does not have any data.  BeginEdit() will allow creation of new data in this row.)

My Code: I have a binding source attached to the data source property of Telerik grid. And in the code I initialize the binding source datasource property to a list of objects. Due to this when the grid pulls up I see the records on the grid. However, when I click on the grid, it does not even go to its event handler but throws this exception.

Kindly let me know what could be done to resolve this issue.

Looking forward to your reply.

Regards,
Swarup

Hi,

had a similar issue in a .net ajax app.
Google pointed me here, but in my case, I was reusing a custom database class inside a select/delete loop.
Creating new instances of it solved it for me.
(Just adding my view since some people didn't manage to fix it..)

Best regards,
Nicolai

Hi,

I realize this is the winforms section (for which I also have a license).
But the result, the cause, and the code could be 100% applicable to the scenario of this thread.
A reminder to create new instances of a class instead of reusing the same one, inside loops...

Best regards,
Nicolai
