有没有办法通过点击Form1按钮在主窗口上显示Form2

Question

我已经设法在MainWindow上的网格中打开Form1，但现在我需要关闭Form1，并在单击Form1上的按钮后在MainWindow的同一网格中显示Form2。

如何做到这一点？

主窗口代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
using System.Windows.Forms;
using System.Configuration;
using Application = System.Windows.Application;
using System.Windows.Forms.Integration;
namespace SolAquaPro
{
/// <summary>
/// Interaction logic for winHomeDash.xaml
/// </summary>
public partial class WinHomeDash : Window
{
public WinHomeDash()
{
InitializeComponent();
}
public void BtnFuel_Click(object sender, RoutedEventArgs e)
{
FuelDash fd1 = new FuelDash();
fd1.TopLevel = false;
WindowsFormsHost host1 = new WindowsFormsHost();
host1.Child = fd1;
stackForms.Children.Add(host1);            
}
}
}

主窗口设计代码为：

Form1(FuelDash(完美地加载到stackForms中，但现在我需要在单击BtnFuelLoad时将Form2(FuelEntry(加载到stackForms中。

Form1代码为：

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();
}
}
}

我知道我需要引用WinHomeDash中的对象，但我一直得到need to reference non static object.

Window Forms与GUI意义上的表单无关。这是一个平台。WPF是Windows窗体的继承者。

在WPF中，您扩展了Window而不是Form。只需删除对Windows窗体的所有引用即可
由于您正在尝试实现单页应用程序，因此您需要用Frame替换Grid。然后让您的所有页面扩展Page。

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

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);
}
}

然后在项目中添加一个新项，并选择Page。这将创建一个带有嵌套文件的.xml文件，该文件包含文件后面的部分类代码：

Form1.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

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

<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

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);
}
}

由于Frame是一个heavyx控件，因为它还支持渲染web源，所以您应该使用ContentControl和DataTemplate来实现页面托管：
