GridView mouse click doesn't make black border appear

[David]

I have a GridView with EditTriggers set to TextInput and F2. When I click a cell it does not get bordered by a black border, but if I use the arrow keys the black border appears. I need a way to show that the mouse click did indeed select the cell the user clicked. Note: I don't mean enter edit mode but rather the cell that would be edited on the next keystroke/F2 press.

Hello,

 I have tested this locally and on our WPF Demos but every time when I clicked on a cell, the black cell border has appeared.

May I ask you to isolate the issue in a sample project which we could check at our side?

All the best,

Here is a sample of the xaml I am using. I will try and get a sample project to reproduce the error.

Please close this thread. We had a data trigger on the IsSelected property.
