MVVM 环境中的 WPF Datagrid RowEditEnding

发布于 2024-12-03 12:26:21 字数 699 浏览 0 评论 0原文

我一直在尝试使用以下方法捕获用户输入数据网格的值

<b:Interaction.Triggers>
    <b:EventTrigger EventName="RowEditEnding">
        <b:InvokeCommandAction  Command="{Binding ReleaseRowEditEndingCommand}" CommandParameter="{Binding SelectedRelease}"/>
    </b:EventTrigger>

但这不起作用，我现在在阅读 this 后明白了这一点StackOverflow 上的文章。所提出的解决方案似乎都是基于直接调用与引发的事件相匹配的方法签名，在这种情况下，

private void OnRowEditEnding(object sender, DataGridRowEditEndingEventArgs e)

是否有人在 MVVM 情况下完成了在 rowedit 后获取值？所有解决方案似乎都将事件紧密绑定到 XAML，如果可能的话，我想避免这种情况。

I've been trying to capture the values that a user enters into a datagrid by using

<b:Interaction.Triggers>
    <b:EventTrigger EventName="RowEditEnding">
        <b:InvokeCommandAction  Command="{Binding ReleaseRowEditEndingCommand}" CommandParameter="{Binding SelectedRelease}"/>
    </b:EventTrigger>

But this doesn't work and I now understand this afte reading this article on StackOverflow. The solutions presented all seem to be based on directly calling a method signature that matches the event being raised, in this case

private void OnRowEditEnding(object sender, DataGridRowEditEndingEventArgs e)

Has anyone accomplished getting the values post-rowedit in an MVVM situation? All the solutions seem to tightly bind the event to the XAML and I'd like to avoid that, if possible.

解决方案实际上比我想象的要容易。我更改了 XAML，现在可以获取视图模型上 RowEditEnding 事件中的值。这是数据网格上数据列的之前：

 <DataGrid.Columns>
    <DataGridCheckBoxColumn Header="Is Paid" Binding="{Binding IsPaid, Mode=TwoWay}" />
    <DataGridTextColumn Header="Amount" Binding="{Binding Amount, Mode=TwoWay}" />
</DataGrid.Columns>

之后

 <DataGrid.Columns>
    <DataGridCheckBoxColumn Header="Is Paid" Binding="{Binding IsPaid, UpdateSourceTrigger=PropertyChanged}" />
    <DataGridTextColumn Header="Amount" Binding="{Binding Amount,  UpdateSourceTrigger=PropertyChanged}" />
</DataGrid.Columns>

The solution was actually easier than I thought. I changed the XAML and I can now get the values in the RowEditEnding event on the View Model. Here's the before on the data columns on the datagrid:

 <DataGrid.Columns>
    <DataGridCheckBoxColumn Header="Is Paid" Binding="{Binding IsPaid, Mode=TwoWay}" />
    <DataGridTextColumn Header="Amount" Binding="{Binding Amount, Mode=TwoWay}" />
</DataGrid.Columns>

After

 <DataGrid.Columns>
    <DataGridCheckBoxColumn Header="Is Paid" Binding="{Binding IsPaid, UpdateSourceTrigger=PropertyChanged}" />
    <DataGridTextColumn Header="Amount" Binding="{Binding Amount,  UpdateSourceTrigger=PropertyChanged}" />
</DataGrid.Columns>
