The solution is rather large, so I don't think it would be advisable for me to post the entire source code. I was hoping that one of the Telerik experts would have seen this behavior before and could easily provide a fix. I will keep researching on my own and try to get it figured out. If I am still having issues I will try and get a "trimmed" down version of the source code for your review.
By the way, the appearance of the "select" text (as seen in the screen shot) only occurs when toggling the filter on and only momentarily. When someone toggles the filter on, the columns are resized to accommodate the filter controls. Once the columns are resized the text "select" is no longer visible. Maybe it has something to do with the resize?
