Binding Visible property of a DataGridColumn in WPF DataGrid

Question

I cannot bind the Visible property of the WPF datagridtextcolumn to a boolean value.

My binding expression is,

{Binding Path=DataContext.IsThisColumn         


        

Answer 1

Hard to say from so little of your code. What is in Visual Studio's Output window (under Debug)? That will often give you a clue as to the problem.

Answer 2

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.

Answer 3

If you can bind from code you can use

BindingOperations.SetBinding(DatagridColumInstance,
                             DatagridColum.VisibilityProperty,
                             myNewBindDef);

Answer 4

I was looking for the same thing and found an execellent way to do it in an article about forwarding datacontext to columns.
