Binding Visible property of a DataGridColumn in WPF DataGrid
c#, data-binding, wpf
Solution
I worked this out.
DataGridCOlumn is not a framework element so the FindAncestor call was failing (DataGridColumn not part of visual tree)
Have to set source property of binding expression to a staticresource and it works fine.
Problem
I cannot bind the Visible property of the WPF datagridtextcolumn to a boolean value. My binding expression is, ``` {Binding Path=DataContext.IsThisColumnVisible, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=Window},Converter={StaticResource vc}} ``` I have checked that the converter works (bool to the visibility enum) and is in scope. If I use the same expression for the header of the column, the header displays 'false' as expected. Visible is a dependency property so should be bindable. Anyone see what Im doing wrong? Or has anyone else been able to bind to the visible property. Regards, Matt
