Show the popupcontent

Hi Lik,

I believe you can set the PopupButton.IsPopupOpen property to true.

private void btnGetOther_Click(object sender, RoutedEventArgs e) { OpenFileDialog dlg = new OpenFileDialog(); dlg.Title = "打开文件"; dlg.Filter = "文件(*." + xmhouzhui + ";*." + gchouzhui + ")|*." + xmhouzhui + ";*." + gchouzhui + "|项目(*." + xmhouzhui + ")|*." + xmhouzhui + "|工程(*." + gchouzhui + ")|*." + gchouzhui + "|所有(*.*)|*.*";

if (dlg.ShowDialog().GetValueOrDefault()) {

} btnGetOther.IsPopupOpen = true; }

 not excute

It worked ok when I tried setting IsPopupOpen in response to a keystroke.  If it's not working in response to a button click, try to dispatch the IsPopupOpen line so that it occurs after any pending input finishes up first, in case that is causing a problem.

I use Caliburn.Micro in project ,  dispatch the IsPopupOpen also not working.

please give me a sample. Thanks.

//view.Dispatcher.BeginInvoke((System.Action)delegate() { //view.Activate(); //view.Focus(); btn.Focus(); btn.IsPopupOpen = true; });

btn.Dispatcher.BeginInvoke((System.Action)delegate() { //view.Activate(); //view.Focus(); btn.Focus(); btn.IsPopupOpen = true; });

Hello, please see the MSDN documentation on it for assistance:

You'd want to use a DispatcherPriority of Background or Input.
