BaseDataList.CellPadding Property

Gets or sets the amount of space between the contents of a cell and the cell's border.

[Visual Basic]
Public Overridable Property CellPadding As Integer
[C#]
public virtual int CellPadding {get; set;}
[C++]
public: __property virtual int get_CellPadding();
public: __property virtual void set_CellPadding(int);
[JScript]
public function get CellPadding() : int;
public function set CellPadding(int);

Property Value

The amount of space (in pixels) between the contents of a cell and the cell's border. The default value is -1, which indicates that this property is not set.

Remarks

Use the CellPadding property to control the spacing between the contents of a cell and the cell's border. The padding amount specified is added to all four sides of the cell.

All cells in the same column of a data listing control share the same cell width. Therefore, if the content of one cell is longer than the content other cells in the same column, the padding amount is applied to the widest cell. All other cells in the column are also set with this cell width.

Similarly, all cells in the same row share the same height. The padding amount is applied to the height of the tallest cell in the row. All other cells in the row are set with this cell height. Individual cell sizes cannot be specified.
