Don't ask why but I have the requirement to draw a border around certain cells in a TableLayoutPanel
.
For example, for simplicity, lets say I have a 1 row, 5 column TableLayoutPanel
. Each cell has a button in it. I would like to draw a box around the first 3 cells and then another box around the last 2 cells. So two boxes total.
Any suggestions on how to accomplish that?
Thanks.
You could use CellPaint
event and draw the border rectangle when needed:
tableLayoutPanel1.CellPaint += tableLayoutPanel1_CellPaint;
The handler:
void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e)
{
if (e.Column == 1 && e.Row == 0)
e.Graphics.DrawRectangle(new Pen(Color.Blue), e.CellBounds);
}
You can draw any kind of border using ControlPaint
:
if (e.Column == 1 && e.Row == 0)
{
var rectangle = e.CellBounds;
rectangle.Inflate(-1, -1);
ControlPaint.DrawBorder3D(e.Graphics, rectangle, Border3DStyle.Raised, Border3DSide.All); // 3D border
ControlPaint.DrawBorder(e.Graphics, rectangle, Color.Red, ButtonBorderStyle.Dotted); // dotted border
}
