如何在WPF中基于bool属性设置背景色 [英] How to set background color based on bool property in WPF

问题描述

我想为GridViewColumn设置背景色，该GridViewColumn在WPF中的列表视图内是数据绑定的。我不确定如何问这个问题对WPF来说还很陌生，否则我不会打扰你们所有人。

I want to set the backgroun color for a GridViewColumn that is databound inside of a listview in WPF. I'm not sure how to ask this question being fairly new to WPF, otherwise I wouldn't have bothered all of you.

我想更改WPF的背景颜色整个行基于我的数据绑定对象中的布尔标志。

I want to change the background color of the whole row, based on a bool flag in my databound object.

在这种情况下，我有一个 CaseDetail对象，当有内部注释时 IsInternalNote，我想更改行的颜色。

In this case, I have, well, a "CaseDetail" object, that when there are internal notes "IsInternalNote" I want the color of the row to change.

如何在WPF中实现此功能？

How can I pull this off in WPF?

我现在所拥有的（非常简单），不会改变颜色。

What I have now, ( very simple ), which does NOT change the color.

<ListView ItemsSource="{Binding}" IsSynchronizedWithCurrentItem="True"  >
            <ListView.View>
                <GridView>
                    <GridViewColumn DisplayMemberBinding="{Binding Date, StringFormat=MMM dd\, yyyy h:mm tt}" Header="Date" Width="Auto" />
                    <GridViewColumn DisplayMemberBinding="{Binding SubmittedBy}" Header="Submitted By" Width="Auto" />
                    <GridViewColumn Width="Auto" Header="Description" x:Name="colDesc">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>                              
                                <ScrollViewer MaxHeight="80" Width="300">
                                    <StackPanel Orientation="Vertical">
                                        <TextBlock Text="{Binding Description}"  TextWrapping="Wrap"   />
                                        <TextBlock Text="{Binding File.FileName}" TextWrapping="Wrap"  />
                                    </StackPanel>
                                </ScrollViewer>                             
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>                    
                </GridView>
            </ListView.View>
        </ListView>

推荐答案

我在尝试执行此操作时遇到了一些麻烦，这样结束

I ran into a few troubles trying to do this, ended up like so

<ListBox ...>
  <ListBox.ItemTemplate>
    <DataTemplate>
      <Border x:Name="BGBorder">
         <!-- --> 
      </Border>
      <DataTemplate.Triggers>
        <DataTrigger 
          Binding="{Binding Path=DataContext.IsAborted, RelativeSource={RelativeSource TemplatedParent}}" 
          Value="True">
          <Setter Property="Background" TargetName="BGBorder" Value="Red">
          </Setter>
        </DataTrigger>
      </DataTemplate.Triggers>
    </DataTemplate>
  </ListBox.ItemTemplate>
</ListBox>

也许还有其他选择，但是一旦我工作了，我就会停止寻找：）

There may be alternatives, but once I had it working, I stopped looking :)
