How to change aspx html heading from code behind?

Question

This is my heading that i want to change from my c# code

 <h3>Please Enter a number between 1 &amp; 
                <asp:Label ID="lbl_max" runat="server"></asp:Label>
            </h3>

I want to replace it with a string

string message = "This is new heading...";

i was thinking about something like this

lbl_max.value = message;

But it's not working... I am absolutely new to asp.net, so forgive me if it's a stupid question...

您可以这样做：

this.lbl_max.Text = "This is new heading...";
