Hi,
I have an aspx page (Default.aspx) with an Accordion control and a button (the page is based on a master page).
Inside one Pane of this Accordion I have an userControl, something like this:

<Content>

<ucDetails:Details ID="userControlDetails" runat="server" />

</Content>

Now I need to access of the Enabled property of the button in the aspx page inside my userControl.

Until now I've tried:

Button btnSend1 = (Button) this.NamingContainer.FindControl("btnSendRequest") ;
Button btnSend2 = (Button) Page.Parent.Parent.FindControl("btnSendRequest");
Button btnSend3 = (Button) Page.Parent.FindControl("btnSendRequest");

The first one return NULL
and the others return exception ("Object reference not set of an instance...").

Where I'm wrong?

Thanks in advance.

Luigi

Hi Luigi

Try on the page and make sure that it works, then test in next level (in the Pane of an Accordion)

WebUserControl.ascx:
====================
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>
<asp:Button ID="Btn1" Text="Button In Usercontrol" runat="server" onclick="Btn1_Click" />
<asp:Label ID="ResultLabel" runat="server"></asp:Label>


WebUserControl.ascx.cs:
=====================
protected void Btn1_Click(object sender, EventArgs e)
{
ResultLabel.Text = ((Button)this.NamingContainer.FindControl("btnSend Request")).Text;
}


default.aspx:
=====================
<asp:Button ID="btnSendRequest" Text="Send Request Button" runat="server" />
<uc1:WebUserControl ID="WebUserControl1" runat="server" />



it works! so you can test in other situations.



your firstname brings 'Luigi Collina' in my mind!!
