关于 DataGridTextColumn的IsReadOnly
1. 以下是绑定方式,但是IsReadOnly不起作用
<DataGrid x:Name="dgTest" ItemsSource="{Binding}" AutoGenerateColumns="False" > <DataGrid.Columns> <DataGridTextColumn Header="Name" IsReadOnly="{Binding Path=Pass}" Binding="{Binding Path= Name}"/> </DataGrid.Columns> <DataGrid>
2. IsReadOnly不是针对某个cell的约定,而是对整列起作用,所以这样的绑定有问题。
3. 可以替换成以下代码:
DataGridTextColumn 换为 DataGridTemplateColumn
<DataGridTemplateColumn Header="Name"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Name,Mode=OneWay}" /> </DataTemplate> </DataGridTemplateColumn.CellTemplate> <DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <TextBox Text="{Binding Path=Name,Mode=TwoWay}" IsReadOnly="{Binding Path=Pass}"/> </DataTemplate> </DataGridTemplateColumn.CellEditingTemplate> </DataGridTemplateColumn>
4. 双击进入编辑界面的时候TextBox没有默认聚焦鼠标光标。修改如下:
FocusManager.FocusedElement="{Binding RelativeSource={RelativeSource Self}}"
<DataTemplate x:Key="cellEditingTemplate">
<local:MultiLineTextBox x:Name="multiLineTxt" Text="{Binding Description}"/>
<DataTemplate.Triggers>
<Trigger SourceName="multiLineTxt" Property="IsVisible" Value="True">
<Setter TargetName="multiLineTxt" Property="FocusManager.FocusedElement" Value="{Binding ElementName=multiLineTxt}"/>
</Trigger>
</DataTemplate.Triggers>
</DataTemplate>
OR
<DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <StackPanel> <TextBox x:Name="editCommentTextBox" Text="{Binding Comment, Mode=TwoWay}" FocusManager.FocusedElement="{Binding RelativeSource={RelativeSource Self}}"> </TextBox> </StackPanel> </DataTemplate> </DataGridTemplateColumn.CellEditingTemplate>
5.cell添加背景颜色CellStyle="{StaticResource dgCellStyle}"
<Style x:Key="dgCellStyle" TargetType="DataGridCell"> <Setter Property="Background" Value="#DDFFDE"/> </Style>
6. 根据是否只读决定单元格的北京颜色
<DataGridTemplateColumn.CellStyle> <Style TargetType="DataGridCell"> <Style.Triggers> <DataTrigger Binding="{Binding Path=IsReadOnly}" Value="False"> <Setter Property="Background" Value="#DDFFDE"/> </DataTrigger> </Style.Triggers> </Style> </DataGridTemplateColumn.CellStyle>
