The above answers are fine but I would add to be sure the div is defined in the designer cs file  This doesn t always happen when adding a div to the  aspx file  Not sure why but there are threads concerning this issue in this forum  Eg  protected global  System Web UI HtmlControls HtmlGenericControl theDiv
