Delete is not an available method in GridViewDataRowInfo[] for Q2. What suggestions do you have for Q2? Upgrading is not an option.

I can't see how this code snippet will work, as it appears to delete the first couple of rows in the GridView and NOT the selected rows.
I know this post is for 2008 Q2 (?) and I'm using 2009 Q1.
What I'm trying to achieve is to delete all of the selected rows from a data bound GridView.
Regards.

Hello Richard Slade,
Thank you for your question.
The snippet copies the selected rows to an array and then removes them from RadGridView one by one. May be you are after a different behavior? What do you mean by "it appears to delete the first couple of rows"?

Hi I am using version Q3 2008 win control library.
I am using this code in my form. It sometimes deleted the rows from the radGridView but sometime not.....
Do I need to make special settings in design time or runt time?

Hello Sunil,
Thank you for writing. I tested the described behavior with the latest build and it behaves correctly. You can upgrade to the latest version or if this is not feasible please send a sample application so that I may debug it and provide a solution. I am looking forward to your reply.
