Question

I have some code that will change the background color of a specific label in a GridView, and that works all well and good.

protected void HighLight_Hours(Label Quarter)
{
    Int32 Hours;
    Int32.TryParse(Quarter.Text, out Hours);
    switch (Hours)
    {
        case 0:
            Quarter.BackColor = Color.Red;
            break;
        case 1:
            Quarter.BackColor = Color.Yellow;
            break;
        case 2:
            Quarter.BackColor = Color.LightGreen;
            break;
    }
}

But instead of calling my function for every single label in my Grid (there are a lot, one for every 15 minutes in a day) is there a way to loop through all the contents of the GridView and set the color accordingly?

This should do it:

 protected void gv_OnRowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {

            foreach (DataControlFieldCell dcfc in e.Row.Controls)
            {
                DataControlFieldCell dataControlFieldCell = dcfc;

                foreach(var control in dataControlFieldCell.Controls)
                    if (control is Label)
                        HighLight_Hours((Label) control);

            }
        }
    }
