I needed to get a pop-up window to come up in ASP.NET. Now while JavaScript happily does this (with the alert(); function, ASP.NET does not. So I needed to work out how to do it. Another wrinkle in this comes from Ajax. None of the JavaScript code seemed to work when placed in an AJAX page.
As I have now been tasked with changing this code and moving from the Anthem Ajax library to a pure MS solution, it was time for this died in the wool VB/C# developer to get his head around getting these scripts working.
To do this:
- Create a simple ASP.NET Web Project
- Right click with the mouse on the Project title (this will be bold)
- Select ‘Add’ and then ‘New Item’
<%@ Page Language="C#" AutoEventWireup="true"
CodeBehind="TestPage.aspx.cs" Inherits="TrustTest.TestPage" %>

</div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" Text="Press Me!"
onclick="Button1_Click" />
</ContentTemplate>
</asp:UpdatePanel>
</form>
</body>
</html>
protected void Button1_Click(object sender, EventArgs e)
{
ScriptManager.RegisterClientScriptBlock(this, typeof(Page),
"alertScript", "alert('you pressed me!');", true);
}
- Select ‘AJAX Web Form’
- Add a Button to the page
- Now add a 'click' event handler to the button
- And there it is. Now whenever you click on the button, a pop up appears saying ‘you pressed me!’
