在WPF中绑定数据时使用路径参数
当然可以。以下是一个 DataGridComboBoxColumn 在 WPF 中使用的示例,并绑定到数据源的代码:
1. 首先,你需要在 XAML 中定义一个 DataGrid 控件,并在其中添加模板列,以包含 DataGridComboBoxColumn:
```xml
<DataGrid AutoGenerateColumns="False">
<DataGrid.Columns>
<!-- other columns... -->
<DataGridTemplateColumn Header="MyComboBox">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<ComboBox ItemsSource="{Binding ItemsSource}"
DisplayMemberPath="DisplayMember"
SelectedValuePath="SelectedValue"
SelectedValue="{Binding SelectedItem, Mode=TwoWay}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
```
2. 接下来,你需要在代码中获取 DataGridComboBoxColumn,并将其绑定到数据源:
```csharp
private void SetupDataGrid()
{
// get the DataGridComboBoxColumn
var comboBoxColumn = dataGrid.Columns.First(c => c.Header.Equals("MyComboBox")) as DataGridComboBoxColumn;
// setup the ItemsSource binding
var binding = new Binding("MyItemsSource") { Source = this };
comboBoxColumn.ItemsSourceBinding = binding;
// setup the DisplayMemberPath binding
binding = new Binding("MyDisplayMemberPath") { Source = this };
comboBoxColumn.DisplayMemberPathBinding = binding;
// setup the SelectedValuePath binding
binding = new Binding("MySelectedValuePath") { Source = this };
comboBoxColumn.SelectedValuePathBinding = binding;
// setup the SelectedValue binding
binding = new Binding("MySelectedValue") { Source = this, Mode = BindingMode.TwoWay };
comboBoxColumn.SelectedValueBinding = binding;
}
// in your ViewModel or code-behind, define the following properties for each of the bindings:
public IEnumerable MyItemsSource { get; set; }
public string MyDisplayMemberPath { get; set; }
public string MySelectedValuePath { get; set; }
public object MySelectedValue { get; set; }
```
这样就可以在 WPF 中使用 DataGridComboBoxColumn 并绑定数据源了。
