CellSpacing Property

BaseDataList.CellSpacing Property

Gets or sets the amount of space between cells.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

'Declaration
Public Overridable Property CellSpacing As Integer

Property Value

Type: System.Int32
The amount of space (in pixels) between cells. The default value is 0.

Use the CellSpacing property to control the spacing between adjacent cells in a data listing control. This spacing is applied both vertically and horizontally. The cell spacing is uniform for the entire data listing control. Individual cell spacing between each row or column cannot be specified.

NoteNote

If you set this property to a value greater than 0 and 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.

The following code example demonstrates how to use the CellSpacing property to specify the spacing between adjacent cells.
