问题描述
我无法在DataGridTextColumn中输入十进制值.如果UpdateSourceTrigger = PropertyChanged，则下面的链接建议我们无法输入十进制值.
I am not able to enter decimal values in DataGridTextColumn. Below link suggest that we cannot enter decimal values if UpdateSourceTrigger = PropertyChanged.
WPF DataGridTextColumn绑定不接受小数位
但是我的要求是我必须保持UpdateSourceTrigger = PropertyChanged.
But my requirement is that I have to keep UpdateSourceTrigger = PropertyChanged.
请提出建议.
以下是我的Datagrid的代码段:
Below is the code snippet for my Datagrid:
<DataGrid x:Name="MyDataGrid" HorizontalAlignment="Left" CanUserResizeColumns="True" VerticalAlignment="Stretch" ItemsSource="{Binding MyDataCollectionListView, Mode=TwoWay}"
SelectionMode="Extended" IsSynchronizedWithCurrentItem="True" SelectionUnit="Cell">
<DataGrid.Columns>
<DataGridTextColumn x:Name="ColMyDataGrid" Header="Price" Binding="{Binding Path=Price, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged, Converter={StaticResource ZeroToEmptyConverter}}" >
<DataGridTextColumn.ElementStyle>
<Style TargetType="TextBlock">
<Setter Property="TextAlignment" Value="Right" />
<Setter Property="Background" Value="#BEFAC4"/>
</Style>
</DataGridTextColumn.ElementStyle>
</DataGridTextColumn>
</DataGrid.Columns>
推荐答案
