Hello, I was having a strange problem in which RadAutoCompleteBoxes within a FormTemplate within a RadGrid were not rendering properly on first load. When clicking edit on a particular row and the edit popup came up, the autocomplete control would simply not appear (though I could see it in the rendered HTML). Oddly, if I cancelled the edit modal and clicked edit again, the autocomplete appeared just fine.
I was able to fix this by adding a DOCTYPE specification on the page:
Unfortunately, after applying this DOCTYPE setting my RadTextBox controls now resize on hover. I removed and reapplied the DOCTYPE a few times to make sure that this was the cause of the resizing behavior. Setting EnableSingleInputRendering="false" reduced the effect, but the height and width seem to increase by about a pixel or so on hover. Removing the DOCTYPE fixes the resizing problem, but then my autocomplete is broken again.
Any help on this matter would be greatly appreciated.
