In my GridView I color rows differently based on the current value of a Combobox column. Each change of the combobox value triggers the PropertyChanged event of the business object.
This works just fine as long as I return one of my own styles in SelectStyle. The row gets correctly drawn using that style.
The problem is, that I want to reset the row style to default (= no style) for one particular combobox value. In this case SelectStyle returns base.SelectStyle(item, container) which is always null (= OK). But the row remains drawn using the previous style although the PropertyChanged event is correctly triggered. If I force the UI to recreate the UI controls of that row (by manually resizing the window), the row is drawn correctly.

What am I missing?

Can I force a redraw of that row to remove the previous style other than by triggering the PropertyChanged event?
I could create my own "Empty Style", but this is what I want to avoid. Any ideas?

Thanks for any help.

Hi Yoan,

Thanks and best regards,

Hi Markus,

The problem has been logged into our Feedback portal as bug report. You can track the status of the issue by following the feedback item: Row's style is not updated when the SelectStyle method of RowStyleSelector returns null. Once we have a progress we will change its status.

The only workaround that I can suggest is to return some "fake" style targeting GridViewRow. For example:

I hope this helps.

Thanks Yoan!

I go with the "fake" style for now.

Best regards,
