GridView Grid Line

1. You can control the visibility of the vertical and horizontal grid lines by setting the appropriate border width of the CellElement in the CellFormatting event handler. If the width value is zero, the lines will not be visible and if it is equal to one, they will be visible. In addition, you can use the DrawBorder property which will govern whether the lines should be drawn or not, disregarding the width even if it is equal to one:

   void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)

   {

   e.CellElement.BorderBottomWidth = 1;

   e.CellElement.BorderBottomColor = Color.Red;

   e.CellElement.BorderRightWidth = 1;

   e.CellElement.BorderRightColor = Color.Blue;

   //If you want to have a RadGridView with no lines at all

   //e.CellElement.DrawBorder = false;

   }

2. As to your second question, you should inherit your form from the RadForm class. For more information, please refer to our online Help Documentation.

1. Open Visual Style Builder and load RadGridView control.
2. In the Control Structure tree, navigate to GridDataCellElement.
3. With the Initial tab selected, navigate to the Expert Mode property grid.
4. In the Box section, set the appropriate Color and Width for the borders.
5. Save and apply the theme to the RadGridView.

I hope this helps. If you have additional questions, feel free to contact me.
