Hi
In btnClick event i want to change back color of label

lbl.BackColor=Color.Red for example

but problem is than i have color like this #F9DA00
and lbl.BackColor = "#F9DA00" does not work.

use imports system.drawing.color

then just use backcolor.red

Here is one way.

Create a style:
<style>
        .mystyle { background-COLOR: #f9da00; }
</style>

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Label1.CssClass = "mystyle"
End Sub

Take a look at the Color.FromArgb() method.

You specify the red, green and blue integer values. You'll need to convert your hex to decimal.

That's a rather complex way wouldn't you think Peter?

I had to open fireworks and enter a color then find its RGB int values.

which are: (249, 218, 0)

and then i added Label1.BackColor = Color.FromArgb(249, 218, 0)

Is there an easier way to obtain the RGB values?

BTW acko this is the answer:
Label1.BackColor = Color.FromArgb(249, 218, 0)

The original poster asked "how do I make lbl.BackColor = "#F9DA00" work?"
In order to set a web control attribute that is of the System.Color type you need to provide it with such. In VB.net you do that with the function I suggested if you want to use a specific color vs. a predefined system color. Unfortunately, yes, this is a bit of a pain and somewhat complicated.

You couldn't do the hex conversion in your head? ;)

Try This:

    Me.BackColor = System.Drawing.ColorTranslator.FromHtml("&H00FFFF" )

Also works like this:

    Me.BackColor = System.Drawing.ColorTranslator.FromHtml("cornflowe rblue")

I agree that this is stupid. When you pick a color in the properties window you see a value of #FF8080. Why can't you just specify a color like that? I know it requies that you enter a value of System.Color, but if Microsoft suppplies you with a value like that, why can't you spcify a value like that in code? To me it is just another inconsistance of .NET. Any ideas why it works this way? I am curious as to why this is.

Thanks,
