Set the row background color according to a cell value

Hi,

At this time I'm able to set the background color of a cell depending
on it's value. I'm able to achieve this by extending the
DataGridTextBoxColumn class and overriding the Paint method:

[code]
protected override void Paint(System.Drawing.Graphics g,
System.Drawing.Rectangle bounds, CurrencyManager source, int rowNum,
System.Drawing.Brush backBrush, System.Drawing.Brush foreBrush, bool
alignToRight)
{
if (internalHighlightInformation != null)
{
object objAtRow = GetColumnValueAtRow(source, rowNum);

//(Values A, C and X are just an example, this values
are set at run-time)
if (objAtRow = "B" || objAtRow = "C" || objAtRow =
"X")
{

backBrush = new SolidBrush(Color.Red);
foreBrush = new SolidBrush(Color.White);
}
}

base.Paint(g, bounds, source, rowNum, backBrush,
foreBrush, alignToRight);
}
[/code]

My problem now is, how can I do this to the full row? At this stage I
know the row number, and the cell, but I don't have any access to the
cells that exist in the same row :( (or do I?)

Any ideas? I just cannot figure out how to do this...

Thanks ahead for all the help.

Best Regards,

L. Pinho

Use the GridViewRowEventArgs event
I realize you're a C# guy, and the sample I'm going to show you is VB.Net,
but it should point you in the correct direction:

Hi,
thanks for the reply

I'm trying to do this at a windows forms level, I don't seem to find
the DoColor event/method anywhere, is a part of which object?

Thanks

This can be accomplished by handling the RowPrePaint event and setting the
background color of the cell accordingly.

void dataGridView1_RowPrePaint(object sender,
DataGridViewRowPrePaintEventArgs e)

{

if(e.RowIndex>-1)

{

someclass sc = (someclass)dataGridView1.Rows[e.RowIndex].DataBoundItem;

this.dataGridView1.Rows[e.RowIndex].Cells[0].Style.BackColor = sc.Color;

}

}
