从父页面动态添加的用户控件的访问控制

Question

I have a Product.aspx page in which i have a asp:panel . I am adding a UserControl in it dynamically using:

protected void Page_Load(object sender, EventArgs e)
{            
    UserControl userControl = (UserControl)this.LoadControl(Programs/Test/Test.ascx);
    this.pnlLayoutDetails.Controls.Add(userControl);
    LayoutPanels = pnlLayoutDetails.Controls[1];
}

I have a button in Product.aspx page. I am hiding some Panel s from UserControl onClick of this button. Code is executing properly but when i see output it shows no effect (all controls are visible).

code for button_click

var pnlLayout = (Panel)LayoutPanels.FindControl("pnlLayout" + layout.LayoutID.ToString());
if (pnlLayout != null)
    pnlLayout.Visible = false;

UPDATE: If i remove ajax panel from aspx page then it works fine. But with ajax panel it creates problem. I am not able to figure it out. Please suggest.

Thanks

I guess it is because you might not have panel in update panel section .

try moving you panel to aspx page. it will solve your problem.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>

            <asp:Panel runat="server" ID="pnlLayoutDetails" >
                    //dynamically added usercontrol
            </asp:Panel>

    </ContentTemplate>
</asp:UpdatePanel>

then execute this it will work.

var pnlLayout = (Panel)LayoutPanels.FindControl("pnlLayout" + layout.LayoutID.ToString());
if (pnlLayout != null)
    pnlLayout.Visible = false;
