c# - Switching between two windows in WPF -

suppose have 2 different windows in wpf application window1 , window2.

based on actions window1, window2 pop while, , based on actions in window1, window2 should close , view returns window1 it's state before window2 appears.

with it's state mean content in controls exists in window1.

to achieve switching used

showdialog();

which looking because need window1 freeze while window2 on.

right problem can't return window1 it's content.

mainwindow (window1).xaml

<window x:class="test.mainwindow"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     title="mainwindow" height="350" width="525"> <grid>     <button content="button" horizontalalignment="left" verticalalignment="top" width="75" margin="193,130,0,0" click="button_click"/> </grid></window> 

button_click

private void button_click(object sender, routedeventargs e) {     window1 window1 = new window1();     window1.showdialog();      //actions      window1.close(); } 

and window1 xaml normal 1 didn't change except made

windowstyle=none

so can't exit right top exit button

if using mvvm can use this:

public static class dialogcloser {     public static readonly dependencyproperty dialogresultproperty =         dependencyproperty.registerattached(             "dialogresult",             typeof(bool?),             typeof(dialogcloser),             new propertymetadata(dialogresultchanged));      private static void dialogresultchanged(         dependencyobject d,         dependencypropertychangedeventargs e)     {         var window = d window;         if (window != null)             window.dialogresult = e.newvalue bool?;     }     public static void setdialogresult(window target, bool? value)     {         target.setvalue(dialogresultproperty, value);     } } 

and in xaml:

 <window x:class="window2"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/     xmlns:xc="clr-namespace:window2"     xc:dialogcloser.dialogresult="{binding dialogresult}" 

then in model can use:

 public bool? dialogresult     {         get;         set;     }
