You should set following properties:
<extToolkit:PropertyGrid ShowSearchBox="False" ShowSortOptions="False" />
Question
I would like to make the Alphabetic Sort and Search bar invisible on the Xceed WPF PropertyGrid. How would that be done? I have read through the list of object attributes for the PropertyGrid and did not see any property relating to the search button as a separate UI element within the PG.
Solution
You should set following properties:
<extToolkit:PropertyGrid ShowSearchBox="False" ShowSortOptions="False" />
OTHER TIPS
Acutally, found it:
PG.ShowSearchBox = false;
PG.ShowSortOptions = false;
