在WPF DataGrid中绑定RowDetails [英] Binding RowDetails in WPF DataGrid

问题描述

我似乎找不到解决方法.

I cant seem to find how to do this.

我不明白为什么rowdetailstemplate的datacontext成为datagrid父级的datacontext.清除时，应从datagrid项目源中选择行项目.

I dont see why the datacontext for a rowdetailstemplate becomes the datacontext of the datagrid parent. When it cleary should choose the rowitem from the datagrid itemssource.

<DataGrid  Grid.Row="1" x:Name="DataGrid" ItemsSource="{Binding Collection}" 
<DataGrid.RowDetailsTemplate>
    <DataTemplate>          
        <TextBox Text="{Binding WhyDoesThisBindingUseDataContextOfDatGridParentAndNotTheRowDataObject}"/>
    </DataTemplate>
</DataGrid.RowDetailsTemplate></DataGrid>

如何获取rowdataobject作为模板的数据上下文?

How can i get the rowdataobject as the datacontext for my template?

推荐答案

看看视觉树.

您绑定到ItemsSource的对象不适用于RowDetailsTemplate.它需要DataGrid Parent的DataContext.

Object which you binds to ItemsSource doesn't apply to RowDetailsTemplate. It takes DataContext of DataGrid Parent.
