I have a datagridview with threecolumns, the first column is a checkbox, the second and third columns will have some similar text in them except for some changes. I want to compare and hilight the text in the second and third columns.

for examplethe second column will havetext: "wonder number 2332"

and the third column will have thetext: "wonder # 2332"

So in this example I want to hilight # 2332 with a different color. Is it possible?

Thanks for your help.

hi Neevarp:

you can use cellpaint event in datagridview and follow code works well in my pc

#123 can be red and aaa still black

void button2_Click(object sender, EventArgs e)

{

this.dataGridView2.Columns.Add(new DataGridViewTextBoxColumn());

this.dataGridView2[0, 0].Value = "aaa#123";

}

private void dataGridView2_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)

{

if (e.RowIndex == 0 && e.ColumnIndex == 0)

{

int index = e.Value.ToString().IndexOf("#");

string black = e.Value.ToString().Substring(0, index);

string red = e.Value.ToString().Substring(index);

e.Paint(e.CellBounds, DataGridViewPaintParts.All & ~DataGridViewPaintParts.ContentForeground);

Font font = this.dataGridView1.Font;

Rectangle strRect = e.CellBounds;

strRect.Width = TextRenderer.MeasureText(black, font).Width;

e.Graphics.DrawString(black, font, Brushes.Black, strRect);

strRect.X = strRect.X+strRect.Width;

strRect.Width =TextRenderer.MeasureText(red, font).Width;

e.Graphics.DrawString(red, font, Brushes.Red, strRect);

e.Handled = true;

}

}
