Answer 1

You could create a public property in you Master Page i.e

public bool ShowPanel
{
    set
    {
        NormalUser.Visible = value;
    }
}

And call it like this

if (Page.Master is NameOfMasterPage)
{
    ((NameOfMasterPage)Page.Master).ShowPanel = false;
}

Answer 2

Because the Panel control is inside a ContentPlaceHolder control, you must first get a reference to the ContentPlaceHolder and then use its FindControl method to locate the TextBox control.

ContentPlaceHolder mpContentPlaceHolder;
Panel pn;
mpContentPlaceHolder = (ContentPlaceHolder)Master.FindControl("PHMainBlock");
if(mpContentPlaceHolder != null)
{
    pn = (Panel) mpContentPlaceHolder.FindControl("NormalUser");
    pn.Visible = false;
}

Here's how I do something similar and it works fine:

if (Page.Master != null)
{
    var tempPanel = Page.Master.FindControl("MessagePanel") as UpdatePanel;
    if (tempPanel != null)
        tempPanel.Visible = true;


    var temp = Page.Master.FindControl("MessageForUser") as MessageToUser;
    if (temp != null)
        temp.PostWarningMessage(message, msgInterval);
}

However, I have "MessagePanel" and "MessageForUser" as controls right above the ContentPlaceHolder. Here's my markup:

<asp:UpdatePanel runat="server" Visible="true" ID="MessagePanel" >
    <ContentTemplate>
        <msg:MainMessage ID="MessageForUser" runat="server" Visible="true" />  
        <br />
    </ContentTemplate>
</asp:UpdatePanel>
<asp:ContentPlaceHolder ID="cphContent" runat="server" Visible="true">              
</asp:ContentPlaceHolder>

If you have your Panel inside of a tag, then you should be able to reference the panel without needing Page.Master.FindControl.

One way would be to solve this problem with javascript (jquery):

$('.NormalUser').hide();
