Highlight a column in tableLayoutPanel after a button click

Hello fellow programmers!

I am new to events and delegates, so any help with the following problem would be greatly appreciated.
I need to update a column of a tableLayoutPanel after clicking a different button in the UI. I have started with the code from another post (thanks to Bob zhu - MSFT):

void Form122_Load(object sender, EventArgs e)

this.tableLayoutPanel1.CellPaint += new TableLayoutCellPaintEventHandler(tableLayoutPanel1_CellPaint);

void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e)

if (e.Row == 0 || e.Row == 2)

Graphics g = e.Graphics;

Rectangle r = e.CellBounds;

new SolidBrush(Color.Blue), r);

Now, instead of using

Form_Load(object sender, EventArgs e)

I need to use

Button1_Click(object sender, EventArgs e)

So, I think the problem is that the sender is different in both cases, and so are the EventArgs. How can this be overcome?

Thank you so much for your help

You can try something like this

Code Snippet

void button1_Click(object sender, EventArgs e)

{

this.highlight = true;

this.tableLayoutPanel1.Invalidate();

}

private bool highlight = false;

void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e)

{

//highlight the second column

if (highlight)

{

if (e.Column == 1)

{

e.Graphics.FillRectangle(Brushes.Coral, e.CellBounds);

}

Well, I found a workaround that is not exactly clean. I use

this.Refresh();

in order to redraw the GUI, but that looks choppy and shows some artifacts.
Hopefully you PROgrammers can find a more elegant solution.

Thanks in advance
