Hi there,

I'm wondering if it's possible to setup the radgridview to allow users to either select a single row or a contiguous set of rows.

I'm not able to achieve this by setting SelectionMode to multiple or extended as these 2 settings will still allow a user to select a non-contiguous set of rows.

Thank you kindly.

Tony

Hello Tony,

Unfortunately by default this is not among the features that we offer. However you can create a custom logic by hooking up to the SelectionChanged event of the GridView and check if the selected set is contiguous or not. 

Hope this helps!

Contiguous based on the current visual state (ie. a particular column is sorted, or combo of columns), or based on the underlying collection order? If you used an underlying collection that supported sorting (ie. CollectionView, CollectionViewSource) you would probably have a more reliable means of verifying they were continguous in all conditions.

Thanks Nik.

I was hoping that there is some hidden setting but yep, worst case we were considering catching this in the underlying event.

Thanks also Tyree for the reply.  We plan to validate against the underlying collection :)
