Hi,

If have found a piece of code that allows you to create own events on a usercontrol. Great! But it doesn't work with me. This is the (changed to my situation) code:

Usercontrol:

public partial class Usercontrols_Modal : System.Web.UI.UserControl
{
    public delegate void ResultCompletedEventHandler(object sender, ReturnResultArgs e);
    public event ResultCompletedEventHandler ReturnResult;

    protected void btnYes_Click(object sender, EventArgs e)
    {
        ReturnResultArgs args = new ReturnResultArgs();
        args.Result = true;
        this.ReturnResult(this, args);
    }
}

public class ReturnResultArgs : EventArgs
{
    // this is a string value I will set using a dropdownlist
    public Boolean Result { get; set; }
}

On the webform (code behind):

public void AskQuestion(object sender, EventArgs e)
{
    modaldelete.ReturnResult +=new Usercontrols_Modal.ResultCompletedEventHandler(modaldelete_ReturnResult);
    //modaldelete.SearchCompleted +=new Usercontrols_Modal.SearchCompletedEventHandler(modaldelete_SearchCompleted);
    modaldelete.Visible = true;
}

protected void modaldelete_ReturnResult(object sender, ReturnResultArgs e)
{
    Response.Redirect("/default.aspx");
}

My code breaks on this.ReturnResult(this, args);. It seems ReturnResult is null and cannot continue.

What am I doing wrong??

Thanks in advance
