Hi devausha,

Try the following code:

protected void Button1_Click1(object sender, EventArgs e)
    {
        string script = "<script language='javascript'>alert('message!')"+"</script>";
        Page.RegisterStartupScript("JavaScript",script);

        HtmlInputText input = new HtmlInputText();
        input.ID = "i1";
        input.Value = "123";
        form1.Controls.Add(input );
       
    }

You're right in saying that it is more complicated with a web app. In a windows app, whenever you run the C# code, whatever happens, happens at that moment. It's pretty straightforward. However, in a web app, all of the C# runs before the page is even rendered in the browser. Therefore, C# in web forms can't really pop up a window.

In order to get a popup, you'll need to do that with JavaScript. The textbox inside the popup should be an <asp:textbox> control. You can use the Ajax Control Toolkit[^] if youre most comfortable with .NET controls. If youre comforatble with jQuery, you should check out jQuery UI[^].

There can be different ways to do it:
1. using Javascript - you need to track the value inserted in textbox via hidden field
2. using AJAX

Here, have a look at these:
