We are using IE11, JavaScript. We have a TreeGrid with buttons positioned below the TreeGrid. When the IE window changes size, we would like the size of the TreeGrid to change as well as the position of the buttons. We have set the width and height of the TreeGrid to a percentage. This does change to size of the TreeGrid, but the right margin changes. Not perfect, but tolerable. When the height of the IE window is increased, the TreeGrid overlaps the buttons. Is there a way to position the buttons relative to the bottom of the window? Is there a way to resize the TreeGrid as the window resizes by the same amount rather than a relative amount?
