CanUserSelect bug

[Tomas]

I think I've found a bug in the GridView control when the property CanUserSelect is set to False I'm still able to select all rows by using the select all shortcut key (ctrl + a).

Btw the PITS crashes after login when clicking the Silverlight section....

has this been included into internal build 2010.1.702.1040?  I have already upgraded to this internal build and the same thing still happens.

because i still have the same problem, or maybe i am doing something wrong?

basically i am trying to get drag and drop on gridviewrow in the radgridview.  this used to work before i upgraded to 2010 Q1.

any help would be great.  I've included the control that i have made for this.  it seems the SetIsSelected is fired regardless which means RaiseSelectionChangedEvent is also fired, i am sure before that wasn't the case when i set CanUserSelect.

            CanUserSelect = false;
            IsSelectionAllowed = true;
        }

        public bool IsDragAllowed {
            get { return (bool)GetValue(IsDragAllowedProperty); }

                IList a = new List<object>();

        }
    }

Hello Sam,

I confirm that the SelectAll (CTRL+A) bug is fixed in 702. I am sending you a  sample application that demonstrates this.

Maybe the assembly references are not updated? Sometimes, if the old assemblies are still contained in the project folder the project might choose to use the old assemblies instead of the new ones.
