Call page method after usercontrol events ends

Question

Hey, How can i call a page method after a usercontol finished his method / fire a parent page method from inside the user control insted?

Answer 1

The most elegant solution would be to have your UserControl raise an event which is handled by the parent page.

In your user control, define an event and raise it:

public partial class WebUserControl1 : System.Web.UI.UserControl {
    public event EventHandler MyMethodIsFinished;

    // ...

    protected void MyMethod {
        // ...
        if (MyMethodIsFinished != null)
            MyMethodIsFinished(this, EventArgs.Empty);
    }
}

In your page, embed the user control and define a handler:

<uc1:WebUserControl1 ID="MyWebUserControl1" runat="server"
                     OnMyMethodIsFinished="MyMethodIsFinishedHandler" />

Then write the handler code in the page:

protected void MyMethodIsFinishedHandler(object sender, EventArgs e) {
    // do something
}

If you need to pass data to your event handler, the recommended way is to subclass EventArgs, as shown in this example.
