c# Net Set Label Colour

Can you try the following:

(e.Row.FindControl("lblGroupName") as Label).BackColor  = Color.FromArgb(Int32.Parse(child.InnerText.Replace("#",""),System.Globalization.NumberStyles.HexNumber));

OR

string hex = "0xFF0000";  
int red   = HexToInt(hex.SubString(2, 2));  
int green = HexToInt(hex.SubString(4, 2));  
int blue  = HexToInt(hex.SubString(6, 2));  
(e.Row.FindControl("lblGroupName") as Label).BackColor  = Color.FromArgb(red, green, blue);
