我对Silverlight和C＃/ XAML有点新，我有一个我无法弄清楚的问题。
我有一个datagrid：
<Grid x:Name="MainDataGrid" Grid.Row="5" >
<data:DataGrid x:Name="datagrid" AutoGenerateColumns="False" HorizontalAlignment="Stretch" IsReadOnly="True" VerticalAlignment="Top" ItemsSource="{Binding DataList}" Height="220" Margin="5">
<data:DataGrid.Columns>
<data:DataGridTextColumn Header="#" Binding="{Binding Number}" />
<data:DataGridTextColumn Header="Business Process" Width="300" Binding="{Binding BusinessProcess}" />
<data:DataGridTextColumn Header="Sub Process" Width="300" Binding="{Binding SubProcess}" />
<data:DataGridTextColumn Header="ITAC" Width="100" Binding="{Binding Itac}" />
<data:DataGridTextColumn Header="Status" Width="200" Binding="{Binding Status}" />
</data:DataGrid.Columns>
</data:DataGrid>
</Grid>
当前绑定到我在ViewModel中创建的一些虚拟数据：
public class ItacViewModel : ViewModelBase
{
public List<data> DataList { get; set; }
public ItacViewModel()
{
var dataList = new List<data>
{
new data(1, "Fixed Asset", "Depreciation", "UL-AC1", "Under Review"),
new data(2, "Fixed Asset", "Depreciation", "UL-AC2", "Complete"),
new data(3, "Order to Cash", "Invoicing", "UL-AC3", "Under Review"),
new data(4, "Order to Cash", "Shipping Goods", "UL-AC4", "Under Review"),
new data(5, "Order to Cash", "Depreciation", "UL-AC5", "Complete"),
new data(6, "Order to Cash", "Depreciation", "UL-AC6", "Under Review"),
new data(7, "Order to Cash", "Depreciation", "UL-AC7", "Complete"),
new data(8, "Stock and Make", "Depreciation", "UL-AC8", "Under Review"),
new data(9, "Stock and Make", "Depreciation", "UL-AC9", "Under Review"),
new data(10, "General Accounting & Reporting", "Depreciation", "UL-AC10", "Complete")
};
DataList = dataList;
}
}
我希望能够在选择单选按钮时过滤数据（单选按钮名称与数据网格中第二列中的名称匹配）：
<StackPanel Margin="2">
<StackPanel Orientation="Horizontal" Margin="1">
<RadioButton GroupName="BusinessProcessesGroup" />
<TextBlock Text="All Business Processes" FontStyle="Italic" />
</StackPanel>
<StackPanel Orientation="Horizontal" Margin="1">
<RadioButton GroupName="BusinessProcessesGroup" />
<TextBlock Text="Fixed Asset" FontStyle="Italic" />
</StackPanel>
<StackPanel Orientation="Horizontal" Margin="1">
<RadioButton GroupName="BusinessProcessesGroup" />
<TextBlock Text="Order to Cash" FontStyle="Italic" />
</StackPanel>
<StackPanel Orientation="Horizontal" Margin="1">
<RadioButton GroupName="BusinessProcessesGroup" />
<TextBlock Text="Purchase to Pay" FontStyle="Italic" />
</StackPanel>
<StackPanel Orientation="Horizontal" Margin="1">
<RadioButton GroupName="BusinessProcessesGroup" />
<TextBlock Text="Stock and Make" FontStyle="Italic" />
</StackPanel>
<StackPanel Orientation="Horizontal" Margin="1">
<RadioButton GroupName="BusinessProcessesGroup" />
<TextBlock Text="General Accounting and Reporting" FontStyle="Italic" />
</StackPanel>
<TextBlock Text=" " />
</StackPanel>
到目前为止，我还没有能够完成这项工作，有人可以给我一些指示吗？
先谢谢
的Dom

您应该将数据绑定到ICollectionView，而不是将DataGrid绑定到List<data>。 ICollectionView使得分组，过滤等操作非常简单，无法在某些数据上实现。
看一下关于如何通过ICollectionView在WPF中实现过滤的this简单但内容丰富的文章

答案 1 :(得分：0)
这是一个微不足道的方法：根据您的无线电按钮的状态修改Datagrid列的Visibility。
XAML：
<data:DataGridTextColumn x:Name="colFixedAsset" Header="Status" Width="200" Binding="{Binding Status}" />
<RadioButton x:Name="radioFixedAsset" GroupName="BusinessProcessesGroup" IsChecked="False" Checked="radioFixedAsset_Checked" Unchecked="radioFixedAsset_Unchecked" />
代码背后：
private void radioFixedAsset_Checked(object sender, RoutedEventArgs e)
{
this.colFixedAsset.Visibility = System.Windows.Visibility.Visible;
}
private void radioFixedAsset_Unchecked(object sender, RoutedEventArgs e)
{
this.colFixedAsset.Visibility = System.Windows.Visibility.Collapsed;
}
如果您是MVVM纯粹主义者，则将布尔属性添加到视图模型中，并将您的radiobuttons的IsChecked属性绑定到那些布尔值。还可以使用converter将datagrid列的Visibility属性绑定到这些布尔值。
