wpf DataGrid控件 设置10行可以编辑

WPF(Windows Presentation Foundation)的DataGrid控件是一个用于显示和编辑数据的表格组件。要设置它只允许用户编辑前10行,你可以通过以下几个步骤来实现:
1. 首先,你需要将DataGrid的数据源绑定到一个可以获取行数的对象,比如ICollectionView、ObservableCollection 或者自定义的数据模型。
2. 在XAML中,创建DataGrid并配置它的`CanUserAddRows`属性为`false`,这样就禁止了默认的新行添加功能。
```xml
<DataGrid ItemsSource="{Binding YourDataSource}" CanUserAddRows="False">
<!-- 其他配置如列头、样式等 -->
</DataGrid>
```
3. 然后,在代码背后,处理`KeyDown`或`PreviewKeyDown`事件来监听当用户试图在第11行及以后输入内容的情况。如果检测到了这种情况,阻止键盘输入或者直接移除光标焦点。
```csharp
private void DataGrid_KeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter && currentRow > 10)
{
e.Handled = true;
// 可能还需要移除当前行的焦点
dataGrid.SelectedIndex = -1;
}
}
private int currentRow => dataGrid.SelectedIndex + 1;
```
这里假设`currentRow`变量表示当前选中的行索引加一,因为在DataGrid中,零索引对应第一行。
