Question

I am using telerik RadGridView control. I would like to control/style the colors of the left, right, top, and bottom borders of all the different column headers in the grid.
Although a solution seemed to be to put a border within a border like this:-

<Border BorderThickness="5,0,0,0" BorderBrush="Green">
    <Border BorderThickness="0,5,0,0" BorderBrush="Red">
        <Border BorderThickness="0,0,5,0" BorderBrush="Pink">
            <Border BorderThickness="0,0,0,5" BorderBrush="Blue">
            </Border>
        </Border>
    </Border>
</Border>

But it removes the content of the header of the column.

Answer 1

You need a ContentPresenter inside which is bound to the header properties.
