I am new to ASP.NETSomeone in this forum helped me how to get the dropdown list work wth user countrol and it is working.In my user control file, VendorListControl.ascx, I have this code below. Please assume that the VendorListControl.ascx.cs works correctly, which is when I select a VendorName, it will fired "ddlVendor_SelectedIndexChanged" to refreshed the "ddlVendorBUList" dropdown list.\[code\]<%@ Control Language="C#" AutoEventWireup="true" CodeFile="VendorListControl.ascx.cs" Inherits="MyNamespace.VendorListControl" %><asp
ropDownList runat="server" ID="ddlVendorList" onselectedindexchanged="ddlVendor_SelectedIndexChanged" AutoPostBack="True" /> <aspropDownList runat="server" ID="ddlVendorBUList" AutoPostBack="True" /> <asp:Label runat="server" ID="lblMessage" /> \[/code\]Next, in my CreateNewRecord.aspx page, I have this code to include both dropdown list from user control.
