System.Web.UI.WebControls Namespace   GridView Class

.NET Framework version 2.0

Sets or retrieves the amount of space between cells.

The property is read/write with a default value of -1, which indicates that no value is specified.

Use the CellSpacing property to control the spacing between adjacent cells in the GridView control. This spacing is applied both vertically and horizontally. The cell spacing is uniform for the entire control. Individual cell spacing between rows or columns cannot be specified.

NOTE: If you set this property to a value greater than 0, and then set the GridLines property to a value that displays the cell borders, a gap is displayed between the borders of adjacent cells. In this situation, the CellSpacing property controls the size of the gap.

To adjust the spacing between the contents of a cell and the cell's border, use the CellPadding property.

The sample below shows how to programmatically set the CellSpacing property of a GridView at run time, depending on user input. The code also demonstrates how to add the user options to a selectable list dynamically.

void Page_Load ( Object src, EventArgs e ) {
   if ( !IsPostBack ) {

      for ( int i=1; i <= 15; i+=2 ) {
         SpaceSelect.Items.Add ( i.ToString ( ) );
      }
      SpaceSelect.SelectedIndex = 2;
   }
   productSpecs.CellSpacing = int.Parse ( SpaceSelect.SelectedValue );
}

Sub Page_Load ( src As Object, e As EventArgs )
   If Not IsPostBack Then
      Dim i As Integer
      For i = 1 To 15 Step 2
         SpaceSelect.Items.Add ( i.ToString ( ) )
      Next i
      SpaceSelect.SelectedIndex = 2
   End If
   productSpecs.CellSpacing = Integer.Parse ( SpaceSelect.SelectedValue )
End Sub
