Question

I am making a page that the user should enter his password again to open and when he navigate away and come back again he should re-enter the password. NO SESSIONS OR COOKIES, just a simple page you enter the password you view it.

How can I do this ?

Answer 1

Use two divs.

One which contains the main content and other containing a textbox and button.

<div id="MainDiv" runat="server" Visible="false">Main Content goes here. </div>

And the login div

<div id="LoginDiv" runat="server" Visible="true">
        <asp:TextBox ID="PasswordTextBox" runat="server"></asp:TextBox>
        <asp:Button ID="LoginButton" runat="server" Text="Button" OnClick="LoginButton_Click" /></div>

On login button click handler, check the password and toggle the visibility.

protected void LoginButton_Click(object sender, EventArgs e)
        {
            if(PasswordTextBox.Text=="Password")
            {
                MainDiv.Visible=true;
                LoginDiv.Visible=false;
            }
        }
