我一直在关注Winforms教程,并使用Caliburn.Micro将其转换为WPF和MVVM。但是,在winforms教程中,它会调用一个新表单。
CreatePrizeForm frm = new CreatePrizeForm();
frm.Show;
我以为我可以使用Caliburn.Micro ActivateItem做类似的事情。我已经包含了一些实验代码。
我的ShellViewModel
public class ShellViewModel : Conductor<object>
{
public void LoadFormOne()
{
MessageBox.Show("You are about to activate FirstChildViewModel");
ActivateItem(new FirstChildViewModel());
}
public void LoadFormTwo()
{
MessageBox.Show("You are about to activate SecondChildViewModel");
ActivateItem(new SecondChildViewModel());
}
}
我的Shellview
<Window x:Class="ConductorTest.ShellView"
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/2006"
xmlns:local="clr-namespace:ConductorTest"
mc:Ignorable="d"
Title="ShellViewModel" Height="450" Width="800">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Button Grid.Column="1" Grid.Row="1" x:Name="LoadFormOne" Content="Load Form One" />
<Button Grid.Column="1" Grid.Row="3" x:Name="LoadFormTwo" Content="Load Form Two" />
</Grid>
</Window>
一个ChildViewModel
public class FirstChildViewModel : Screen
{
public FirstChildViewModel()
{
}
}
child 观
<Window x:Class="ConductorTest.FirstChildView"
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/2006"
xmlns:local="clr-namespace:ConductorTest"
mc:Ignorable="d"
Title="FirstChildView" Height="450" Width="800">
<Grid>
<TextBlock>You are now in First Child View</TextBlock>
</Grid>
</Window>
所以我的想法是,如果我单击LoadFormOne按钮,它将执行,
ActivateItem(new FirstChildViewModel());
然后会创建一个FirstChildViewModel(),就像
DisplayRootViewFor<ShellViewModel>();
然后在标准bootstrapper.cs中启动新的WPF表单。
但显然不是。
我缺少什么或Caliburn.Micro没有提供简便的方法?
谢谢
最佳答案
为此有一个IWindowManager
接口(interface)。
public class ShellViewModel : Conductor<object> {
private readonly IWindowManager window;
public ShellViewModel(IWindowManager window) {
this.window = window;
}
public void LoadFormOne() {
MessageBox.Show("You are about to activate FirstChildViewModel");
var model = new FirstChildViewModel();
ActivateItem(model);
window.ShowDialog(model);
//or
//window.ShowWindow(model); //For non-modal
DeactivateItem(model);
}
}
关于c# - 有没有简单的Cailburn.Micro方法来显示新的窗口/对话框?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/52140832/
