我正在学习XAML,这是一个基本问题 我想绑定数据,以便通过XAML在设计时生成(在运行时它运行正常)。
<Window x:Class="GridTest.MainWindow"
Name="This"
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>
<DataGrid AutoGenerateColumns="False"
Height="200"
Width="308"
HorizontalAlignment="Left"
Margin="25,23,0,0"
Name="dataGrid1"
VerticalAlignment="Top"
ItemsSource="{Binding ElementName=This, Path=MyData}">
<DataGrid.Columns>
<DataGridTextColumn Header="No"
Width="Auto"
Binding="{Binding Id}"
IsReadOnly="True" />
<DataGridTextColumn Header="Title"
Binding="{Binding Title}"
IsReadOnly="True" />
<DataGridTextColumn Header="Description"
Binding="{Binding Description}"
IsReadOnly="True" />
</DataGrid.Columns>
</DataGrid>
public partial class MainWindow : Window
{
public List<Item> MyData
{
get
{
return myData;
}
}
List<Item> myData;
public MainWindow()
{
myData = new List<Item>
{
new Item{ Id=5, Description="Brown Car", Title="my car"},
new Item{Id=1,Description="sweet dog", Title="my dog"},
};
InitializeComponent();
}
}
public class Item
{
public string Title
{
set;
get;
}
public string Description
{
set;
get;
}
public int Id
{
set;
get;
}
}
答案 0 :(得分:4)
序列如下:
1)将代码从MainWindow类移动到自定义类并设置DataContext
属性:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.DataContext = new MainWindowViewModel();
}
}
public class MainWindowViewModel
{
public MainWindowViewModel()
{
myData = new List<Item>
{
new Item{ Id=5, Description="Brown Car", Title="my car"},
new Item{Id=1,Description="sweet dog", Title="my dog"},
};
}
public List<Item> MyData
{
get
{
return myData;
}
}
List<Item> myData;
}
2)更改DataGrid
:
ItemsSource="{Binding MyData}"
3)添加名为DataGridSample.xaml
的新ResourceDictionary,打开其属性(右键单击 - &gt;属性),将BuildAction
属性设置为DesignData并清除{{1}的值} property。
4)复制此代码,但将名称空间CustomTool
从vm
更改为您的名称:
WpfApplication1
5)返回<vm:MainWindowViewModel xmlns:vm="clr-namespace:WpfApplication1">
<vm:MainWindowViewModel.MyData>
<vm:Item Id="1" Title="My dog" Description="Sweet dog" />
<vm:Item Id="5" Title="My car" Description="Brown car" />
</vm:MainWindowViewModel.MyData>
</vm:MainWindowViewModel>
并将下一行添加到MainWindow.xaml
元素,其中所有声明均为:
Window
之后你可以切换到设计模式,你会看到数据网格有两行。
