| This property will render for only certain controls. For example, Table, Panel, DataGrid, Calendar, and ValidationSummary will render this property. It will also work for CheckBoxList, RadioButtonList and DataList if their RepeatLayout property is RepeatLayout.Table, not RepeatLayout.Flow. |
In general, only controls that render as a <table> tag can display a background color in HTML 3.2, whereas almost any control can in HTML 4.0.
For controls that render as a <span> tag (including Label, all validation controls, and list controls with their RepeatLayout property set to RepeatLayout.Flow), this property will work in Microsoft Internet Explorer version 5 and later, but not in Microsoft Internet Explorer version 4.
The following example illustrates how to set the BackColor property of the Table control, which is inherited from the WebControl base class.
