如何響應警報窗口上的點擊
下面的示例顯示如何響應終端用戶單擊警報窗口的文本。為了響應這些操作,將處理AlertControl.AlertClick事件。
在本例中,假設警報窗口用于在收到新電子郵件時向最終用戶顯示通知。當創(chuàng)建一個新的警報窗口時,一個自定義MailData對象與該窗口相關聯(lián),該對象包含關于收到的電子郵件的信息,并且在處理AlertControl.AlertClick事件時訪問和處理它。
C#:
private void ShowAlertWindow() { Form owner; string caption, text, hotTrackedText; Image image; MailData mailData; // Initialize the owner, caption, text, hotTrackedText, image and mailData // ... // Show an alert window with these parameters alertControl1.Show(owner, caption, text, hotTrackedText, image, mailData); } private void alertControl1_AlertClick(object sender, AlertClickEventArgs e) { // Get and process the data associated with the current alert window. MailData mailData = e.Info.Tag as MailData; ShowEmail(mailData); } private void ShowEmail(MailData mailData) { //... } public class MailData { //... }
