To trigger an onClick function associated with an element of a specific notification, you need to call the RaiseHtmlElementClick method with two parameters:

• The unique element ID, which is set in the HTML markup.
• The specific alert instance. All active HTML-designed alerts are stored in the HtmlPopupList collection. You can browse it to find the required notification.

The code below finds the notification that has "#2" in its "MessageText" string, and emulates user clicking the OK button of this notification.

C#

AlertHtmlPopup target = alertControl1.HtmlPopupList.Find(x =>
    (x.DataContext as AlertData).MessageText.Contains("#2"));
alertControl1.RaiseHtmlElementClick("okButton", target);

VB.NET

Dim target As AlertHtmlPopup = alertControl1.HtmlPopupList.Find(Function(x) (TryCast(x.DataContext, AlertData)).MessageText.Contains("#2"))
alertControl1.RaiseHtmlElementClick("okButton", target)
