我有一个listtemplate正在使用样式的列表框.样式指定带有数据触发器的边框,根据属性设置要折叠的边框的可见性.这工作正常,但我仍然可以看到列表中折叠的每个项目的非常窄的行.我希望有人可以帮助设置可见性,以便没有可见的痕迹,因为当连续项目折叠时这是非常明显的.

datatemplate指定了一个带有dockpanel的外边框 - 然后有一个与之对接的stackpanels.

任何帮助表示赞赏.

那么这是一个简化的模板:

<DataTemplate x:Key="myTemplate">
    <Border BorderThickness="0">
        <Border.Style>
            <Style>
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Path=IsActive}" Value="False">
                        <Setter Property="Border.Visibility" Value="Collapsed" />
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <DockPanel LastChildFill="True" HorizontalAlignment="Stretch">
            <StackPanel DockPanel.Dock="Right" HorizontalAlignment="Right"  >
                <TextBlock Text="{Binding Path=SeqNo, Converter={StaticResource SeqToTextConv}}"/>
                <Label Content="..." />
            </StackPanel>
        </DockPanel>
    </Border>
</DataTemplate>

我读的关于这个主题越多,我理解的就越少,所以如果下面看起来完全不在墙上,请提前道歉.

我有一个包含flowdocument的usercontrol - 一个带有相应viewmodel的视图.目的是将其发送到预览窗口,用户可以在该窗口中查看文档并进行打印.

我从http://www.eggheadcafe.com/tutorials/aspnet/9cbb4841-8677-49e9-a3a8-46031e6​​99b2e/wpf-printing-and-print-pr.aspx的示例中提取了一些代码.

当调用以下内容时

Public Shared Sub PrintPreview(owner As Window, data As FormData)

        Using xpsStream As New MemoryStream()

            Using package__1 As Package = Package.Open(xpsStream, FileMode.Create, FileAccess.ReadWrite)

                Dim packageUriString As String = "memorystream://data.xps"

                Dim packageUri As New Uri(packageUriString)

                PackageStore.AddPackage(packageUri, package__1)

                Dim xpsDocument__2 As New XpsDocument(package__1, CompressionOption.Maximum, packageUriString)

                Dim writer As XpsDocumentWriter = XpsDocument.CreateXpsDocumentWriter(xpsDocument__2)

                Dim visual As New Form(data)

                Dim printTicket As New PrintTicket()

                printTicket.PageMediaSize = A4PaperSize

                writer.Write(visual, printTicket)

                Dim document As FixedDocumentSequence = xpsDocument__2.GetFixedDocumentSequence()

                xpsDocument__2.Close()

                Dim …
