Hi,

I don't think there is any built-in way to do this. But this should be possible using a CreationFilter to manipulate the HeaderUIElement in for the column.

A CreationFilter allows you to trap for the creation and positioning of any UIElement in the grid and you can change the size and position of the elements.

If you are not familiar with CreationFilters, then I recommend searching the forum for "CreationFilter". There are lots of samples that show how to use them. Also, get the Infragistics UIElementViewer Utility. It will be a huge help in determining what elements you need to manipulate.

CreationFilters are an advanced technique and there's a bit of a learning curve, but they are a very powerful tool. Let me know if you get stuck and I will try to point you in the right direction.
