我创建了一个用户控件类库,并在其中使用了ResourceDictionary文件.现在,我想在WPF应用程序中使用我的usercontrol,但我必须在我的项目中再次添加ResourceDictionary文件!如果我不添加它,它会带来ResourceDictionary文件,并在MergeDictionaries块上显示错误!我错过了什么!？

资源字典是:

    <ControlTemplate x:Key="MoveThumbTemplate" TargetType="{x:Type s:MoveThumb}">
        <Rectangle Fill="Transparent" Cursor="Hand"/>
    </ControlTemplate>

    <Style x:Key="ItemStyle" TargetType="ContentControl">
        <Setter Property="Width" Value="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type Canvas}},Path=ActualWidth}"/>
        <Setter Property="MinHeight" Value="60"/>
        <Setter Property="Height" Value="60"/>
        <Setter Property="Content" Value="MyTextBox"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ContentControl">
                    <Grid DataContext="{Binding RelativeSource={RelativeSource TemplatedParent}}">
                        <s:MoveThumb Template="{DynamicResource MoveThumbTemplate}"/>
                        <ContentPresenter Name="MainControl" Content="{TemplateBinding ContentControl.Content}"
                                          Margin="5,0,10,0"/>
                        <Grid Opacity="0" Margin="-3">
                            <s:ResizeThumb Height="3" Cursor="SizeNS" VerticalAlignment="Top" HorizontalAlignment="Stretch"/>
                            <s:ResizeThumb Height="3" Cursor="SizeNS" VerticalAlignment="Bottom" HorizontalAlignment="Stretch"/>
                        </Grid>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>    
</ResourceDictionary>

添加到用户控件:

<UserControl.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Resources/MoveResizeThumb.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</UserControl.Resources>

我ObservableCollection在ViewModel中有一个静态MarketList,它以Table下列方式绑定:

<FlowDocumentScrollViewer Height="216" VerticalAlignment="Top" Margin="-7,2,7,0" >
    <FlowDocument>
        <Table CellSpacing="0" Name="MBPTable"  >
            <Table.DataContext>
                <MultiBinding  UpdateSourceTrigger="Explicit"  Mode="TwoWay" Converter="{StaticResource indexerConverter}">
                    <Binding Path="MarketList" UpdateSourceTrigger="PropertyChanged" NotifyOnSourceUpdated="True" Mode="TwoWay" BindsDirectlyToSource="True"  />
                    <Binding Path="MBPindex"  Mode="TwoWay"   />
                </MultiBinding>
            </Table.DataContext>
        <Table.Resources>
            <local:IndexerConverter x:Key="indexerConverter"></local:IndexerConverter>
        </Table.Resources>

Table包含ListView哪个绑定到MarketList的Property.

<ListView  Name="MarketByPriceList" Width="300" ItemsSource="{Binding MarketByPriceList, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" AlternationCount="2" Margin="0,15,0,0" >
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Orders"  Width="48"  DisplayMemberBinding="{Binding MBP_NoofBuy_Orders, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" ></GridViewColumn>
            <GridViewColumn Header="Bid Qty" Width="48"  DisplayMemberBinding="{Binding MBPBID_Qty,  UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" ></GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>

这是转换器方法

    public object Convert(object[] values, Type …

我有一个由滑块Grid缩放/缩放ScaleTransform的。在运行时，许多UIElement被添加到此Grid。

我想显示一些工具提示，但没有扩展！我应该怎么做？

例如：Grid具有scaleX和scaleY 2，因此我设置了新的ScaleTransform（0.5，0.5），但没有帮助。似乎最相似的值是0.740。为什么？甚至Grid的LayoutTransform.Inverse都将缩放比例值设置为0.5。

XAML：

<ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Height="Auto" Width="Auto" Name="graphScrollViewer" ScrollChanged="graphScrollViewer_ScrollChanged">
<Grid Margin="0,0,0,0" Name="graphGrid" Width="Auto" Height="Auto" ScrollViewer.IsDeferredScrollingEnabled="True"  MouseLeftButtonDown="graphGrid_MouseLeftButtonDown" MouseLeftButtonUp="graphGrid_MouseLeftButtonUp" MouseMove="graphGrid_MouseMove">
    <Grid.LayoutTransform>
        <ScaleTransform ScaleX="{Binding ElementName=sldZoom, Path=Value}" ScaleY="{Binding ElementName=sldZoom, Path=Value}" />
    </Grid.LayoutTransform>
</Grid>
</ScrollViewer>

<Slider Minimum="0.1" Maximum="20" Value="1" x:Name="sldZoom" Panel.ZIndex="10" Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="0,0,20,20" Height="23" Width="100"  ValueChanged="sldZoom_ValueChanged"/>  

后台代码：（将Rectangle方法（MouseEnter事件）动态添加到网格）

private void rect_MouseEnter(object sender, MouseEventArgs e)
{
    RectToolTip = new TextBlock();
    RectToolTip.HorizontalAlignment = HorizontalAlignment.Left;
    RectToolTip.VerticalAlignment = VerticalAlignment.Top;
    RectToolTip.TextAlignment = TextAlignment.Center;
    RectToolTip.Height = this.HeaderTwoHeight …
