我在 DataGridTemplateColumn.CellEditing DataTemplate 中设置了一些东西。我希望当单元格编辑加载并显示模板时,应将键盘焦点赋予模板中的某个控件。
考虑这个例子,当你进入编辑模式时,文本框不是以键盘为中心的:
<Window x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<DataGrid Name="dg" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTemplateColumn Header="Title">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Title}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<TextBox Text="{Binding Title}"/>
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>
<DataGridTemplateColumn Header="Value">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Note}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<TextBox Text="{Binding Note}"/>
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
</Grid>
</Window>
Class MainWindow
Private Sub Window_Loaded(ByVal sender As Object,
ByVal e As RoutedEventArgs) Handles MyBase.Loaded
Dim data As New List(Of Item) From
{New Item,
New Item,
New Item}
dg.ItemsSource = data
End Sub
End Class
Public Class Item
Private Shared Number As Integer = 0
Sub New()
Number += 1
End Sub
Public Property Title = "Title " & Number.ToString
Public Property Note = "Note " & Number.ToString
End Class
