  I’m just starting out using the WPF FlexGrid to convert from the standard WPF DataGrid and I’m trying to bind the IsVisible property of some GridColumns in a FlexGrid to a property in my view model to control when they are visibile or not.

  IsVisibile is not a DependencyProperty, so I can’t bind to it. GridColumn is not a DependencyObject, so I can’t use an AttachedProperty. Is there some other way that is recommended to dynamically control GridColumn visibility? There are plenty of hacky ways to solve it, but I was hoping a good method already exists.

  Hi,
  
  You can make use of Binding Proxy as shown below.
  
  ```
  
  local:FlexGridExtended.BindableSettings
  
  <local:BindableColumnSettings ColumnName=“Name” DataContext=“{Binding Path=Data, Source={StaticResource proxy}}”
  
  IsColumnVisible=“{Binding VisibleColA}”></local:BindableColumnSettings>
  
  <local:BindableColumnSettings ColumnName=“School” DataContext=“{Binding Path=Data, Source={StaticResource
  
  proxy}}”
  
  IsColumnVisible=“{Binding VisibleColB}”></local:BindableColumnSettings>
  
  </local:FlexGridExtended.BindableSettings>

  I have also attached a sample based on MVVM approach. Please let me know if any other details are needed from my end.
