Assembly: System.Web (in System.Web.dll)
Use the GridLines property to specify whether the border between the cells of a data listing control is displayed. This property is set with one of the GridLines enumeration values. The following table lists the possible values.
Value | Description |
|---|---|
None | No cell border is displayed. |
Horizontal | Only the upper and lower borders of the cells in a data listing control are displayed. |
Vertical | Only the left and right borders of the cells in the data list control are displayed. |
Both | All borders of the cells in a data listing control are displayed. |
The following code example demonstrates how to use the GridLines property to display both the horizontal and vertical gridlines in a data-bound control.
