Hi all,

I know how to give a simple "msgbox" in ASP.Net / VB.Net:

Response.Write("<Script language=Javascript> window.alert('my message') </Script>")

But I can't find anwhere how to do a 2-button "msgbox", e.g., to get the user's confirmation that they really want to delete an item.

I really appreciate any help!

Hi

You can use the confirm method as below:

If (confirm("Are you sure to delete?"))
    return true;
else
    return false;

Regards
Mike

Hi Mike,

Thanks for your reply, but I think you're assuming I know more than I do (which isn't too much)... the code you suggested doesn't work in straight VB. I've seen examples on the web where they modify the HTML, but I can't get those to work either.

What I finally found was to add the code to Page_Load:
  ibtnSave.Attributes.Add("language", "javascript")
  ibtnSave.Attributes.Add("OnClick", "return confirm('Are you sure?');")
When OK is clicked, it runs the button click event code; when Cancel is clicked it doesn't.

Again, thanks for your reply.

It sounds like you are trying to mix client side behavior with server side behavior. You can not use the client side methods (alert, confirm, prompt) to bring back data to the server.

What you are seeing is that when the user answer 'OK', the postback button gets "clicked" because the onclick handler is returned 'true'. If they answer 'Cancel', the handler is return false, which basically cancels the user's click action and the form never posts.

In order to achieve what you are looking for, you need to write some more javascript to take the return value from the message box at the client, put them in a server control, such as a hidden form element, and then let the form postback so you can evaluate the resulting value (from the hidden element) and then do what you wish on the server side.
