有没有办法通过单击 Form1 按钮在 MainWindow 上显示 Form2
[英]Is there a way to show Form2 on MainWindow from button click on Form1
问题描述
I have managed to get Form1 to open in my grid on the MainWindow but now I need to close Form1 and show Form2 in the same grid on the MainWindow after I click a button on Form1.
我已经设法让 Form1 在 MainWindow 的网格中打开，但现在我需要在单击 Form1 上的按钮后关闭 Form1 并在 MainWindow 的同一网格中显示 Form2。
How can this be done?如何才能做到这一点？

Form1(FuelDash) loads perfectly into stackForms but now I need to Load Form2(FuelEntry) into stackForms when I click BtnFuelLoad . Form1(FuelDash) 完美加载到stackForms但现在我需要在单击stackForms时将 Form2(FuelEntry) 加载到BtnFuelLoad 。
Form1 code is: Form1代码是：
using System;
using System.Windows.Forms;
using System.Windows.Forms.Integration;
using static SolAquaPro.WinHomeDash;
namespace SolAquaPro
{
public partial class FuelDash : Form
{
public FuelDash()
{
InitializeComponent();
}
private void Timer1_Tick(object sender, EventArgs e)
{
}
private void BtnFuelLoad_Click(object sender, EventArgs e)
{
this.Close();
}
private void BtnClose_Click(object sender, EventArgs e)
{
this.Close();
}
}
}
I know I need to reference an object in WinHomeDash but I keep getting need to reference non static object.我知道我需要在 WinHomeDash 中引用WinHomeDash ，但我一直need to reference non static object.

Window Forms has nothing to do with a form in sense of GUI. Window Forms 与 GUI 意义上的形式无关。 It's a platform.这是一个平台。 WPF is the successor of Windows Forms. WPF 是 Windows Forms 的继任者。
In WPF you extend Window instead of Form.在 WPF 中，您扩展Window而不是 Form。 Just delete all references to Windows Forms.只需删除所有对 Windows Forms 的引用即可。
Since you are trying ti implement a singe page application, you would replace the Grid with a Frame .由于您正在尝试实现单页应用程序，因此您可以将Grid替换为Frame 。 Then let all your pages extend Page .然后让您的所有页面扩展Page 。
WinHomeDash.xaml WinHomeDash.xaml
<Window>
<StackPanel>
<!-- Navigation pane -->
<StackPanel Orientation="Horizontal">
<!-- Example how to navigate from outside the pages -->
<Button Click="LoadForm1_OnClick" Content="Form 1" />
<Button Click="LoadForm2_OnClick" Content="Form 2" />
</StackPanel>
<Frame x:Name="stackForms"
NavigationUIVisibility="Hidden" />
</StackPanel>
</Window>
WinHomeDash.xaml.cs WinHomeDash.xaml.cs
partial class WinHomeDash : Window
{
private void LoadForm1_OnClick(object sender, RoutedEventArgs e)
{
Page form1 = new Form1();
this.stackForms.Navigate(form1);
}
private void LoadForm2_OnClick(object sender, RoutedEventArgs e)
{
Page form2 = new Form2();
this.stackForms.Navigate(form2);
}
}
Then add a new item the project and select Page .然后添加一个新项目项目和 select Page 。 This creates a.xaml file with a nested file containig the partial class code-behind file:这将创建一个包含部分 class 代码隐藏文件的嵌套文件的 .xaml 文件：
Form1.xaml表格1.xaml
<Page>
<StackPanel>
<TextBlock Text="This is the first page." />
<!-- Example how to navigate from within the page -->
<Button Content="Navigate to next page"
Click="LoadForm2_OnClick" />
</Page>
Form1.xaml.cs Form1.xaml.cs
public partial class Form1 : Page
{
public Form1()
{
InitializeComponent();
}
private void LoadForm2_OnClick(object sender, RoutedEventArgs e)
{
Page form2 = new Form2();
this.NavigationService.Navigate(form2);
}
}
Form2.xaml表格2.xaml
<Page>
<StackPanel>
<TextBlock Text="This is the first page." />
<!-- Example how to navigate from within the page -->
<Button Content="Navigate to previous page"
Click="LoadPreviousForm_OnClick" />
</Page>
Form2.xaml.cs Form2.xaml.cs
public partial class Form2 : Page
{
public Form1()
{
InitializeComponent();
}
private void LoadPreviousForm_OnClick(object sender, RoutedEventArgs e)
{
// Navigate to previous page using the history
this.NavigationService.GoBack()
// Navigate to previous page using an explicit content
Page form1 = new Form1();
this.NavigationService.Navigate(form1);
}
}
Since Frame is a heavyx control as it also supports to render web sources, you should use a ContentControl an DataTemplate to implement the page hosting:由于 Frame 是一个重型控件，因为它还支持呈现 web 源，因此您应该使用 ContentControl 和 DataTemplate 来实现页面托管：
