I am using a radgrid where in the ClientSettings, I have AllowScroll="true" and UseStaticHeaders="true". This grid is in a user control sitting on a webform that is loaded into a MasterPage content area. What's happening is that the grid is sizing correctly on the page but the masterpage width and height are getting expanded based on the number of columns and rows we add to the grid. In other words, it's as if the page is trying to account for the space occupied by the grid even though we set the scroll to true. A thing to note about this is that I want the grid to horizontally scroll, so we deliberately are settings the pixels on each of the columns in the grid to exceed the width of the grid to invoke the horizontal scroll. And after doing a little more testing, as soon as UseStaticHeaders is set to true, the effect described above occurs. Have the headers locked in for vertical scrolling is essential, so we would like to keep the UseStaticHeaders set to true. Any help would be greatly appreciated. Thanks.
