Use the BorderWidth property to specify a border width for a control.

NoteNote

This property does not work with all Web server controls. It applies only to controls that display as a table, such as Table and DataGrid.

This property is set with a Unit object. If the Value property of the Unit contains a negative number, an exception is thrown.

NoteNote

The border width can be expressed only in pixels for browsers earlier than Microsoft Internet Explorer version 5. All unit types are supported in Microsoft Internet Explorer version 5 and later. Refer to the specific control for details.

The following example illustrates how to set the BorderWidth property of the Table control, inherited from the WebControl base class.
