Question

I have this function:

[System.Web.Services.WebMethod]
public static string EditPage(string nodeID)
{
    DataTable dt = new DataTable();
    using (SqlConnection con = new SqlConnection(Global.conString))
    using (SqlCommand cmd = new SqlCommand("contentPageGetDetail", con))
    {
        cmd.Parameters.Add("@ID", SqlDbType.UniqueIdentifier).Value = Global.SafeSqlLiteral(nodeID, 1);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.ExecuteNonQuery();
        using (SqlDataAdapter da = new SqlDataAdapter(cmd))
        {
            da.Fill(dt);
        }
    }


   return nodeID;
}

I want to grab variables such as:

<asp:HiddenField ID="hfNodeID" runat="server" />

or

<asp:RadioButtonList id="rblContentTypesGetAll" OnLoad="rblContentTypesGetAll_Load" runat="server" >
</asp:RadioButtonList>

in my Web Form but When I try to reference their IDs they don’t auto complete and can’t be found. What am I missing? Is it even possible?

The WebMethod is static – it will not have access to the form controls. They’re not executed in the context of the page – you’ll need to get the required values using client side scripting and pass them in.
