I've searched high and low for what seemed would be a simple and frequently used method to access the properties of a drop down contained in a Ajax UpdatePanel without finding anyone who seems to have needed to do this or who has solved it. Maybe Microsoft decided nobody would ever want to do such a weird thing!
I have users with various permission levels. Depending on their level, on page load I need to disable drop downs which are contained within Ajax Updatepanels.
I can expose the properties of the UpdatePanels themselves but they do not support the enable property, only invisible which is no help.
Anyone know how this is done ?
Thanks
Aren't you able to just set the Enabled property of the appropriate DropDownList's?
Dont depends only on UI elements enable/disable state. Also enusre the User level in server side. Can pls post some code i mean in which point you want to disable the dropdown list.
Use CascadingDropDown control in AJAXControlToolKit

Hi,
Are you using the AJAX extension version 1.0.61025.0 ?
I'm using this one. The controls inside UpdatePanel can be accessed directly. For instance:
<%@. Page Language="C#" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"> protected void Page_Load(object sender, EventArgs e) { DropDownList1.Enabled = false; }</script><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:DropDownList ID="DropDownList1" runat="server"> </asp:DropDownList> </ContentTemplate> </asp:UpdatePanel> </div> </form></body></html>
