changing text color in label in C# with conditions

Question

I'm trying to change the color of a text in a label per condition.

I have tried the following option but none of them works:

if (gameNameTXT.Text != "")
{
    pubName.ForeColor = System.Drawing.Color.Green;
    pubName.ForeColor = System.Drawing.Color.FromArgb(11, 102, 35);
    pubName.Attributes.CssStyle.Add("color", "green");
}

( pubName in the ID of the label)

I have located the snipped code in the Page_Load section and/or the Page_Init section.

What I want is that the color of the text changes to green if the user wrote something in the text box.

Answer 1

do you try on onChange event of gameNameTXT?
may be you need set AutoPostBack=true
