Get the ok from a javascript alert in asp.net code behind

Question

1) I've an updatepanel in an aspx page containing a gridview and an asp.net button

2) The user select some griview's items and press the asp.net button to launch some CRUD stuff on the DB via code-behind.

3) Before to start this CRUD stuff a javascript alert must appear to ask: "are you sure to continue?"

4) When the user press "OK" on the alert then the code behind can continue to operate the CRUD stuff

I was able to implements the first three points, but I'm blocked on the fourth: how the hell I can trap in code behind the "OK" pressed in the alert javascript?

Can anyone help me?

Thank you very much.

Answer 1

What about you call confirm just 'before' you starting the crud?

To accomplish this, just include onClientClick="return confirm('Are you sure?');" on the asp.net button.

As you asked here is a simple example using command:

ASP.NET

   <asp:Button ID="cmdRegister" runat="server" Text="Register"  OnCommand="cmdRegister_Command" OnClientClick="return confirm('Are you sure?');" CommandArgument="10"></asp:Button>

Code Behind:

  protected void cmdRegister_Command(object sender, CommandEventArgs e)
  {
    int argument = Convert.ToInt32(e.CommandArgument);
    if (argument == 10)
    {
      //somework
    }
  }
