Conditional cell hiding
posted

I'm new in WPF and xamlDataGrid. I try to hide cell using trigger. Cell visibility is based on value of other bounded object's property (IsChecked)
It works but there is empty space where collapsed column was placed.
If I don't use trigger in style and simply collapce cell without condition (see commented xaml code) then there is no empty space.

How to collapse cell using trigger without remaining empty space?

 Off: How to format xml-code in this forum?

    Hello, 

    I was not able to reproduce this. Can you please give us the code you are using to hide the CellPresenter in procedura code?
