我試圖在我的應用程序中顯示一個標準的MessageBox作爲模式窗口,但它最終成爲非模態。 在第一個調用中,在下面的代碼中,我顯示了一個標準的MessageBox,它顯示爲模態,因爲它應該。在第二次調用中,即使我抓取主窗口調度程序,它也不會顯示爲模式。WPF應用程序中的模態消息框
Dispatcher disp = Application.Current.MainWindow.Dispatcher;
//First call, shown MODAL
if (this.messageService.ShowYesNo("Do you want to update the Word document, this will regenerate inspectiondata for document", "") == MessageBoxResult.Yes)
{
using (new WaitCursor())
{
_eventAggregator.GetEvent<ProgressBarRequestShow>().Publish("");
worker = new BackgroundWorker();
worker.DoWork += delegate(object s, DoWorkEventArgs args)
{
AITUpdateProgressDelegate update = new AITUpdateProgressDelegate(UpdateProgress);
this.docService.UpdateWorddocument(this.docService.GetCurrentDocumentFilePath, update);
};
worker.RunWorkerCompleted += delegate(object s, RunWorkerCompletedEventArgs args)
{
try
{
// Second call NOT MODAL
disp.Invoke((Action)delegate()
{
this.messageService.ShowInformation("Document generated, choose Open in Word in main toolbar to show document", "");
});
_eventAggregator.GetEvent<ProgressBarRequestHide>().Publish("");
}
finally
{
}
};
worker.RunWorkerAsync();
}
}
爲什麼不使用WPF窗口來自定義消息框? –
我需要更多地學習文檔,默認情況下信息消息框不是默認的,需要設置所有者 – klashagelqvist
