SelectedItems always returns 0

[Robert]

Hi,

my RadGrid uses a CheckBox for row selection as descrbed in the documentation. When the CheckBox is clicked, the following Codebehind is executed:

((sender as CheckBox).Parent.Parent as GridItem).Selected = (sender as CheckBox).Checked;

This line has been taken from the example code in the documentation. Now, I want to perform some action on the selected items. Therefore I use the SelectedItems Property but it always returns 0. I already red this thread: http://www.telerik.com/community/forums/thread/b311D-bdcmhk.aspx

and I belive it should be working ... but for some reason it doesn't. It seems to me, as if the selection is not precessed properly so the CheckBox is checked but the SelectedItems collection is never updated. What's wrong with my code?

Best Regards,

Robert

Hi Robert,

Basically, if you use advanced binding or data source control for grid item generator, the SelectedItems collection should be modified properly to host the selected rows in the grid. You can see that on the following online demo of the product:

http://demos.telerik.com/ASPNET/Prometheus/Grid/Examples/Programming/SelectRowWithCheckBox/DefaultCS.aspx (the selected items are output at the bottom of the grid)

If you are unable to solve the issue yourself, please start a formal support ticket and submit a working version of your project, illustrating the problem. We will examine your complete implementation and will get around to you with our findings.
