Open Sample

To make the Grid fill in the full width/height of the browser window, set both ScrollWidth and ScrollHeight properties to 100%

The html, body, form elements need to have the height set to 100% as well (from CSS).

Resize the browser window and the grid will resize accordingly.

<obout:Grid runat="server" ... > <ScrollingSettings ScrollHeight="100%" ScrollWidth="100%" /> </obout:Grid>

html, body, form
{
    height: 100%;
    padding: 0px;
    margin: 0px;
    overflow: hidden;
}
