BaseDataList.CellSpacing Property

Gets or sets the amount of space between cells.

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

public virtual int CellSpacing { get; set; }
/** @property */
public int get_CellSpacing ()

/** @property */
public void set_CellSpacing (int value)

public function get CellSpacing () : int

public function set CellSpacing (value : int)

Property Value

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.

   <script runat="server">
 
      ICollection CreateDataSource()

         DataTable dt = new DataTable();
         DataRow dr;
 
         // Define the columns of the table.
         dt.Columns.Add(new DataColumn("IntegerValue", typeof(Int32)));
         dt.Columns.Add(new DataColumn("StringValue", typeof(string)));
         dt.Columns.Add(new DataColumn("CurrencyValue", typeof(double)));
 
         // Populate the table with sample values.
         for (int i = 0; i < 9; i++) 
         {
            dr = dt.NewRow();
 
            dr[0] = i;
            dr[1] = "Item " + i.ToString();
            dr[2] = 1.23 * (i + 1);
 
            dt.Rows.Add(dr);
         }
 
         DataView dv = new DataView(dt);
         return dv;
      }
