[SOLVED] Why am I seeing binding errors related to AreRowDetailsFrozen and HeadersVisibility for Datagrids in WPF?

Why am I seeing binding errors related to AreRowDetailsFrozen and HeadersVisibility for Datagrids in WPF?

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.DataGrid', AncestorLevel='1''. BindingExpression:Path=AreRowDetailsFrozen; DataItem=null; target element is 'DataGridDetailsPresenter' (Name=''); target property is 'SelectiveScrollingOrientation' (type 'SelectiveScrollingOrientation') System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.DataGrid', AncestorLevel='1''. BindingExpression:Path=HeadersVisibility; DataItem=null; target element is 'DataGridRowHeader' (Name=''); target property is 'Visibility' (type 'Visibility')

These errors appear in the immediate window in WPF. Why does this happen, and how can I stop it?

Solution

This post here has details of workarounds for this issue. This one worked for me:

Add the following code to global styles:

<Style.Triggers>
     <Trigger Property="HeadersVisibility" Value="Column">         
          <Setter Property="RowHeaderWidth" Value="0" />
     </Trigger>
</Style.Triggers>
