The easiest way to show a msgbox in asp.net is the next:
Response.Write("<script>alert('Text')</script>")

You can use a msgbox object but it has some problems.

Its fine, but depends to the button!
What about the times when there is no button?!

i have tested, if button, you can use "Response.Write("<script>alert('Text')</script>")", if no button, such as in your edit column of a datagrid, i think you can use "button.Attributes.Add("onclick", "window.alert('text');")",but i have not tested.

You can use Response.Write(...) with button and without button.

If you want to show your message by clicking on your datagrid
column you only have to catch the event and show the message with response.write(....). You don´t need to add de attribute.

To validate you can use next to your textbox....
<asp:RequiredFieldValidator id="NameOfTheID" runat="server" ErrorMessage="'The username can't be NULL!"></asp:RequiredFieldValidator>

I have always used this for displaying a messagebox
Works fine !

Public Sub AlertUser(ByVal strMessage As String)
   Dim strScript As String

   strScript = "<script>"
   strScript = strScript & "alert('" & strMessage & "');"
   strScript = strScript & "</script>"

   Page.RegisterStartupScript("ClientScript", strScript)
End Sub

The best way I've found to do this is to create a static class MessageBox with a static method Show(), which will give you the ablility to to still use the syntax MessageBox.Show("Your Message"); and convert it into window.alert("Your Message");.

The javascript alert() function is limited as it doesn't provide any overloads for changing the caption of the MessageBox, but it still works nicely.

I've written a how to on my blog at: http://sceptermt.blogspot.com/2008/0...lass-in-c.html that shows the source code that I used in C# for my web application and details on how it works.

You could also write overloads for the static show() method to allow the class to do a javascript confirm() or a prompt(). I haven't needed that functionality yet so I've just kept it simple.
