我在Datagrid中有一个Datepicker / Textblock。我可以选择,并输入日期,但是,输入键或单击事件不会将日期输入数据网格。如果我在数据网格外部单击,它将接受日期值。我很困惑发生了什么。有什么想法会发生这种情况吗?解决方案是什么?
这里的代码似乎很简单。
<DataGrid x:Name="dgTestingDates" ItemsSource="{Binding TestingDates}" CanUserAddRows="True" AutoGenerateColumns="False" HorizontalAlignment="Left" HorizontalContentAlignment="Stretch" ColumnWidth="*" Margin="21,300,0,0" VerticalAlignment="Top" Height="165" Width="245" >
<DataGrid.Columns>
<DataGridTemplateColumn >
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=Time,UpdateSourceTrigger=LostFocus}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<DatePicker SelectedDate="{Binding Path=Time,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>

这解决了我的问题。...
public class CustomDatePicker : DatePicker
{
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
if (Template != null)
{
var box = (TextBox)Template.FindName("PART_TextBox", this);
box.AddHandler(KeyDownEvent, new KeyEventHandler(OnTextBoxKeyDown), true);
}
}
private void OnTextBoxKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
// The DatePicker set this as handled, which breaks the DataGrid commit model.
e.Handled = false;
}
}
}
