问题 I have 2 windows. Lets call them A and B. A is opening B with a ShowDialog(). So I am opening B - When the user minimizes B or gets it into the back somehow and he tries clicking window A again its blocked (as it should be), but is there an Event that I can catch up onto when this happens ? I am trying to achieve bringing the blocking window B into the front when hes trying to access window A with window B opened. Codeexample: Thats how Window A is opened from the Mainwindow WindowA windowA =

问题 I think this is a bug in the WPF framework, without going into depths of my program and why I am doing what I am doing, I wrote a simple test application to prove my theory. Can this issue be confirmed? What are possible workarounds for a series of dialogs to be executed before putting the application into its run loop? using System; using System.Collections.Generic; using System.Configuration; using System.Data; using System.Linq; using System.Windows; namespace ShowDialogWindow { ///

问题 Which is a better way to show a modal dialog? form1 frm=new form1(); frm.showDialog() or (new form1()).showDialog(); 回答1: Neither one is "better" than the other; they are perfectly equivalent! However, in this particular case, both are wrong . The ShowDialog method requires you to call the Dispose method on the form. Unlike the Show and Close combination, this is not done automatically. From MSDN: When a form is displayed as a modal dialog box, clicking the Close button (the button with an X

Unexpected behaviour of System.Windows.Window.ShowDialog() when no other windows are open. Any idea why?

问题 I picked up on this (with some effort) when my WPF MVVM application tried to show two consecutive error dialog windows before the main window was launched: After OKing the first window, the application went into a loop and the second error dialog never showed up. I fixed the problem, but I was hoping someone could enlighten me as to why this happened. It seems that, if there are no non-modal open windows, if one dialog window has been closed, all new dialog windows are immediately closed,

WPF Routed Commands and ShowDialog Windows

由 心已入冬 提交于 2019-12-03 22:15:52
I was wondering how a window opened through ShowDialog is treated in the Visual Tree. For example, Window A opens Window B through a ShowDialog. When firing a routed command on Window B, Window A does not receieve the command (even though it is listening for it). Is there any way to make this work? Thanks! Jon We run into this situation all the time in our application. We use the Window.Owner property and ICommandSource.CommandTarget property for this. For example, in Window A: DialogWindow windowB = new DialogWindow(); windowB.Owner = this; windowB.ShowDialog(); Then, in DialogWindow, all the
