I have a sortable radgrid. We are using skin="" and styling the grid ourselves. With no skin, there are no arrows or indicators next to the text to tell the user this column is sortable. The text on sortable fields is bold and when you mouse over a "Click here to sort" hint comes up. But I have just been told by my client that this isn't a good enough indicator. They want arrows to tell the user that it's sortable. There currently are no arrows which I'm sure is proper for no skin. However, when the user clicks the sort text, an up or down arrow shows up. I tried adding an image in ItemDataBound and it worked ok but as soon as the user clicks the text I get both my image AND the up/down arrow from the grid. Is there any way to either add both up and down arrows on default state or hide the arrows when sorted so I can add my own image in ItemDataBound?
