Hello.

How can i access controls declared on the parent page from user controls?
for example, i have a parent page called "main.aspx"

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<%@ Register TagPrefix="MyControl" TagName="UserControl1" Src="myUserControl.ascx" %>


<asp:Button ID="showPanel" Text="ShowPanel" runat="server" />

<asp:Panel ID="Panel1" runat="server" visible="false">

<MyControl:UserControl1 ID="UserControl1" runat="server">
</asp:Panel>



"Default.aspx.vb"

Partial Class _Default
    Inherits System.Web.UI.Page

Protected Sub showPanel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles showPanel_Click
Panel1.visible = true
End Sub
End Class


"myUserControl.ascx"
<%@ Control Language="VB" AutoEventWireup="false" CodeFile="myUserControl.ascx.vb" Inherits="myUserControl" %>

<table>
<tr>
<td>
<asp:Button ID="HidePanel" Text="HidePanel" runat="server" />
</td>
</tr>
</table>

"myUserControl.ascx.vb"

Partial Class _Default
    Inherits System.Web.UI.Page

Protected Sub HidePanel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles HidePanel_Click

' This is the place to hide the panel1 from parent page.

End Sub
End Class


So, this is clear that when i click the HidePanel button, the panel from parent page will be hide.
Please help me. thanks
