How to open multiple popup window's in ASP.NET on button click

I have struck in one doubt.

I am using one asp button. In this button click event I'm using if and else condition.

If block shows one popup and else block show another popup:

if (Session["id"] != null)
{
      //one popup 
}
else
{
    //Second pop up Show
}

<asp:Button ID="btnAvailabilty" runat="server" class="btn btn-success" Text="Check Availability" OnClick="btnAvailabilty_Click" />

You need to write that in client side if you need to write a JavaScript code there, 

if (Session["id"] != null) {
    ClientScript.RegisterStartupScript(this.GetType(), "something", 
       "alert('Your message');",
    true);
} else {
    ClientScript.RegisterStartupScript(this.GetType(), "something", 
       "alert('Your other message');",
    true);
}

You can also try to run the message variable to be changed, while leaving maximum of the code in one statement, 

var message = "Your message";
if (Session["id"] == null) {
    message = "Your other message";
}

ClientScript.RegisterStartupScript(this.GetType(), "something", 
           $"alert({message});", // Requires C# 6
        true);

If you can write native JavaScript, such as Razor, then that will go like, 

<script>
    @if (Session["id"] != null) {
        alert('Your message');
    } else {
        alert('Your other message');
    }
</script>

Depends on your need.
