Can't change color on text.

In my Grid, I can change the color of the background but not the forecolor
(text). Why is that?

protected void Process_Click(object sender, EventArgs e)
{
foreach (GridViewRow gvr in GridView1.Rows)
{
if (((Label)gvr.FindControl("lblWhich")).Text == "3")
{
gvr.BackColor = System.Drawing.Color.Green; <------
Works
gvr.ForeColor = System.Drawing.Color.Yellow; <------
Not Working
}
}

}

Sounds to me like you want to be setting the color of the Label (based
on your "if" statement), not of the row. The row is just a container
- hence why background color has an effect.

But is there a way to do it for the whole row?

I don't really want to go through the whole row and look for all the labels.

Thanks,

Also, googling I found the following code that does similar to what I was
doing.

But he didn't have any labels but had BoundFields. Why would that work?
