Hello, <BR><BR>I'm having problems passing the value of a variable to a user control. I got a suggestion yesterday, but still can't seem to get it to work, and advice is greatly appreciated.<BR><BR>I've no problem passing predefined strings <BR><Temp:header Runat="server" ID="header" strPath="../"/> <BR><BR>But if I try and pass the value of a variable I can't<BR><Temp:header Runat="server" ID="header" strPath="<%=strPath%>"/> <BR><BR>The suggestion I got was to<BR><BR>Sub Page_Load(s As Object, e As EventArgs) <BR> strPath = "../" <BR><BR> header.strPath = strPath <BR>End Sub <BR><BR>but this returns:<BR>Reference to a non-shared member requires an object reference.<BR><BR>thanks<BR>the best method I've found to passing values to a user control is to use the querystring. You could also possibly use codebehind pages, never tried it though, text files, & session variables.Thanks for the reply jeff, problem is that the variable is a constant defined on the aspx page that is then passed to the user controlTry something like this
