Repeater And Adding A Function

[orangelightbulb]

Hi
I have a repeater and want to add a function to a field
the function is this


public static void CreateSendertMessage(string server)
{
string s_html;
s_html = server.ToString();

}

*** the s_html is just for example

the repeater is
<asp:Repeater ID="Grd_subpages" runat="server">
<ItemTemplate>
<%# CreateSendertMessage(DataBinder.Eval(Container.Dat aItem, "content_name"))%>
%>
</ItemTemplate>
</asp:Repeater>

the error i am getting is
Compiler Error Message: CS1502: The best overloaded method match for '_Default.CreateSendertMessage(string)' has some invalid arguments
please can anyone help
thanks
