        <AppThemeBinding.Light>
            <telerikDataGrid:DataGridColumnHeaderStyle 
                    BackgroundColor="#ffffff"
                    BorderColor="#F0EFF3"
                    BorderThickness="1"/>
        </AppThemeBinding.Light>
        <AppThemeBinding.Dark>
            <telerikDataGrid:DataGridColumnHeaderStyle 
                    BackgroundColor="#2a3137"
                    BorderColor="#505d68"
                    BorderThickness="1"/>
        </AppThemeBinding.Dark>
    </AppThemeBinding>
</telerikDataGrid:DataGridTextColumn.HeaderStyle>

I just used the approach outlined in the link below to set a custom color for the selected row in my RadGridView control.

WPF DataGrid | SelectedBackground and MouseOverBackground | Telerik UI for WPF

This approach seems to have worked just fine for the case when the user clicks on a row to select it.  However, when the SelectedItem property of the grid view is set in code through data binding, the selected row color reverts to the default value.  Only upon clicking the row again does it display using the color that I defined.

Am I missing something?

Thanks!
