Hiding columns based on a certain selected value

[Farhan]

Hi,

I am developing a hierarchical data grid where by the values of the parent row can show/hide certain columns. I did setup a bindable value from the parent row's object  to the IsVisible property of the GridViewDataColumn but the binding never gets invoked even though all conditions are met correctly. How do I go about achieving this?

Thanks,
Farhan

Hello Farhan,

You do the following:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Country}"
       IsVisible="{Binding DataContext.IsVisibleProperty, RelativeSource={RelativeSource AncestorType=telerik:RadGridView}}"/>

In this case IsVisibleProperty is a property of the parent item. Still, I am sending you a sample project that you may use for testing the solution immediately.
