数据模板中的数据绑定不起作用

发布于 2024-12-05 17:42:36 字数 1660 浏览 1 评论 0原文

我有 UserControl 对多个演示文稿进行过滤，而该演示文稿又具有 ContentControl。内容是各个演示文稿之间有所不同的单独过滤控件。

该方案在视觉上按预期工作，但数据绑定却不然。输出中没有数据绑定错误。 DataContext 来自一个名为 PimMasterVm 的视图模型，否则它看起来连接正确（即 5 个可用人员的状态等）

有人可以帮我解决这个问题吗？

干杯，

过滤控件

在此处输入图像描述

<Grid>
    <Border Style="{StaticResource FilterPanelBorderStyle}">
        <StackPanel Orientation="Horizontal" x:Name="myFilterPanel" >
            <ContentControl x:Name="ctrlFilters" 
                            ContentTemplate="{Binding Path=FilterContentKey, Converter={StaticResource filterTemplateContentConv}}" />
            <Button x:Name="btnClearFilter" Style="{StaticResource FilterPanelClearButtonStyle}" />
            <Label x:Name="lblStatus" Style="{StaticResource FilterPanelLabelStyle}" Content="{Binding Status}" />

        </StackPanel>
    </Border>

</Grid>

数据模板（资源）

<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>

原文

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.

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)

Can someone help me trouble shoot this?

Cheers,

Filtering Control

enter image description here

<Grid>
    <Border Style="{StaticResource FilterPanelBorderStyle}">
        <StackPanel Orientation="Horizontal" x:Name="myFilterPanel" >
            <ContentControl x:Name="ctrlFilters" 
                            ContentTemplate="{Binding Path=FilterContentKey, Converter={StaticResource filterTemplateContentConv}}" />
            <Button x:Name="btnClearFilter" Style="{StaticResource FilterPanelClearButtonStyle}" />
            <Label x:Name="lblStatus" Style="{StaticResource FilterPanelLabelStyle}" Content="{Binding Status}" />

        </StackPanel>
    </Border>

</Grid>

Data Template (resource)

<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>

“ctrlFilters”ContentControl 的 DataContext 中有当前视图模型，将其绑定到 Content 属性：

...

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

...

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}}" />

...
