How to find out if full row is selected with SelectionMode="Extended"

[Jan]

In my gridview I want to prevent the user from deleting entire rows but allow to delete (multiple cells) by pressing the DEL-key. Works fine so far but how can I prevent that the user accidentally selectes multiple rows and presses delete. So far I just count the number of selected fields for delete and show a warning but there's got to be a nicer way.

Is there any property in the radgridview that tells me, if multiple rows are selected?

Row selection as such is needed for copy/paste so removing anything is not an option.

 

thanks for your help in advance!

Hi Jan,

The control does not expose such property which holds how many rows are selected. What I can suggest you is to used the SelectedItems collection of the control. You can use the Count property of the collection to get how many rows are selected.

var selectedRows = this.MyRadGridView.SelectedItems.Count;

Give this approach a try and let me know if it works for you.
