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