数据模板中的数据绑定不起作用 [英] Data bindings in Data Template not working

问题描述

我有UserControl为几个演示文稿进行过滤，后者又有一个ContentControl。内容是在演示文稿中不同的各个过滤控件。

I have UserControl to do filtering for several presentations, which in turn has a ContentControl. The content are the individual filtering controls that vary among the presentations.

该方案的工作原理可视化，但是数据绑定没有。输出中没有数据绑定错误。 DataContext来自一个视图模型调用PimMasterVm，否则它似乎正确连接（即5个可用的人的状态等）。

The scheme works as intended visually, but the data bindings do not. There are no data binding errors in output. The DataContext is from a view model call PimMasterVm, which otherwise seems correctly wired (ie, the status of 5 avalable people, etc)

有人可以帮我解决这个问题吗？

Can someone help me trouble shoot this?

干杯，

<DataTemplate x:Key="pimFilterContent">
    <StackPanel Orientation="Horizontal" >
        <cc:SearchTextBox x:Name="stbLastNameFilter" 
            Style="{StaticResource FilterPanelSearchTextBoxStyle}"
            Text="{Binding Path=LastNameFilter, UpdateSourceTrigger=PropertyChanged}" 
                        />
        <cc:SearchTextBox x:Name="stbFirstNameFilter" 
            Style="{StaticResource FilterPanelSearchTextBoxStyle}"
            Text="{Binding Path=FirstNameFilter, UpdateSourceTrigger=PropertyChanged}" 
                        />
    </StackPanel>
</DataTemplate>

推荐答案

在 DataContext 的ctrlFiltersContentControl，将其绑定到内容属性：

There is current view model in DataContext of the "ctrlFilters" ContentControl, bind it to Content property:

...

    <ContentControl x:Name="ctrlFilters" 
                    Content="{Binding}"
                    ContentTemplate="{Binding Path=FilterContentKey, Converter={StaticResource filterTemplateContentConv}}" />

...
