Obtaining the value of a JavaScript confirm popup in C#.NET

I am trying to implement a javascript confirm popup that returns a value from the code behind. When the user selects the ok button on the confirm popup, certain code will execute, and if they select cancel, different code will run.

Is there a way to retrieve the selected value from the code behind?

This is what my code currently looks like:

if (ClientScript.RegisterStartupScript(typeof(Page), "Confirm", "<script type='text/javascript'>return Confirm('Do you Want to Delete');</script>"))
{
    db.Deletedevicedate();
    clear();
}
else
{
    clear();
}
c#javascriptasp.net

Answer №1

When the client clicks, make sure to include this line of code:

OnClientClick = " return confirm('Are you sure you want to continue?');"

For example:

   <asp:Button runat="server" OnClientClick = " return confirm('Are you sure you want to continue?');" />

If they click 'ok', then the button click event will be triggered. If not, there won't be a page postback. Include your code for deleting data in the button click event.

Answer №2

Consider implementing ajax for a smooth user experience.

Below is the javascript code snippet:

 var result = confirm("Are you sure you want to delete?");
if (result) 
{
    //perform ajax request to delete data from the database
    return true;
} 
else 
{
    return false;
}

Answer №3

To seamlessly integrate this functionality into your existing code, my suggestion is to include a concealed input field on your webpage (which can be accessed in the back-end of your code) and populate its value using JavaScript:

<script type='text/javascript'>$('#yourhiddenfield').val(Confirm('Are you sure you want to proceed?'));</script>

Answer №4


   if
   {
       ImageButton DeleteButton = (ImageButton)e.Row.FindControl("btnDelete");
       DeleteButton.Attributes.Add("onclick", "javascript:return confirm('Are you sure you want to delete this payment method?');");
   }
   else
   {
       // No need for any alerts or extra features here
   }
