I'm currently coding a button which will delete a record from a database if clicked. However, I want some sort of confirmation after they click it so there are no accidents. I was imagining a popup box that tells them they are about to delete this record with two buttons cancel and OK. If cancelled, nothing happens, but if OK is pressed, then the server would execute the delete as coded. How would I do this in asp/vb?

• 1 Oh there surely will be accidents. If the user clicked the button by accident, he will get confused and click through your dialog by accident... – EFraim Commented Nov 22, 2009 at 20:40
• The underlying JavaScript function that you want is confirm("orly?"); – Justin Johnson Commented Nov 22, 2009 at 21:45

Here is a button with a confirmation message :

<asp:Button runat="server" ID="btnDelete" 
     OnClick="btnDelete_Click" 
     OnClientClick="return confirm('Do you want to delete the record ? ');" />

Here is the way to add confirm client script at server side :

btnDelete.Attributes.Add("onclick", 
        "return confirm('Do you want to delete the record ? ');")

Adding Client-Side Message Boxes in your ASP.NET Web Pages is a great tutorial to make client-side confirmation messages like this:
