今天我在試圖做的時候變得很瘋狂,我的想法很簡單。Silverlight如何在數據網格列模板中綁定我的usercontrol
我想
我已經搜索並嘗試了幾種組合,並沒有出現工作
誰能幫助我能夠創建我的用戶,並在我的DataGrid中使用它在我的專欄的模板?
public class User
{
public string Name { get; set; }
public bool IsValid { get; set; }
}
partial class MyControl : UserControl
{
private string _value;
public string Value
{
get { return _value; }
set { _value = value;
txt.Text = value;
}
}
public MyControl()
{
InitializeComponent();
}
}
<Grid x:Name="LayoutRoot" Background="White">
<TextBlock x:Name="txt" Text="[undefined]"></TextBlock>
</Grid>
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
var items = new List<User>();
items.Add(new User{Name = "user 1", IsValid = true});
items.Add(new User { Name = "user 2", IsValid = false });
myGrid.ItemsSource = items;
}
}
<Grid x:Name="LayoutRoot" Background="White">
<sdk:DataGrid x:Name="myGrid" AutoGenerateColumns="False" IsReadOnly="True">
<sdk:DataGrid.Columns>
<sdk:DataGridTemplateColumn Header="Name">
<sdk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<SilverlightApplication1:MyControl Value="{Binding Name}"></SilverlightApplication1:MyControl>
<!--<TextBlock Text="{Binding Name}"></TextBlock>-->
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
</sdk:DataGrid.Columns>
</sdk:DataGrid>
</Grid>
編輯: 我也試過以下,但我爬電網無結果:
<Grid x:Name="LayoutRoot" Background="White">
<TextBlock x:Name="txt" Text="{Binding Value}"></TextBlock>
</Grid>
public partial class MyControl : UserControl
{
public DependencyProperty ValueProperty =
DependencyProperty.Register("Value",
typeof(string),
typeof(MyControl),
new PropertyMetadata(OnValueChanged));
public string Value
{
get
{
return (string)GetValue(ValueProperty);
}
set
{
SetValue(ValueProperty, value);
NotifyPropertyChanged("Value");
}
}
private static void OnValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
((MyControl) d).Value = (String)e.NewValue; //ERROR: here I got always empty string
}
public MyControl()
{
InitializeComponent();
}
}
謝謝,非常感謝。完美的作品 – muek 2011-05-02 14:39:02
