Question

I have this very simple control below. And on the page that i use this control I’d just like to be able to say: ucMessagePanel.SetMessage(...), but it does not allow me to declare a static method. I tried doing it with Static properties and that works just fine, but shouldn’t I also be able to use static methods?

    <center>
    <asp:Panel ID="pnlMessage" runat="server" >
        <asp:Label ID="lblMessage" runat="server" />
    </asp:Panel>
</center>


public partial class ucMessagePanel : System.Web.UI.UserControl
{        
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    public static void SetMessage(string message, string mssgCssClass)
    {
        lblMessage.Text = message;
        pnlMessage.CssClass = mssgCssClass;
    }
}

You don’t need static methods. When you declare the user control in the ASPX page, you can reference it directly by the ID.

In the ASPX:

<uc:SomeUserControl ID="UserControl1" runat="server" ...>

And in the code behind:

UserControl1.SetMessage("Some message");

In the user control, change the method to something like this:

public void SetMessage(string Message)
{
    lblMessage.Text = Message;
}
