HorizontalAlignment Issue

本文关键字：Issue HorizontalAlignment | 更新日期: 2023-09-27 18:14:10

我使用Silverlight 5和Telerik库。
我设置了RadPanelBar, HorizontalAlignment为拉伸状态。第一次显示我的控件时，它采用其父控件的大小。但问题是，当我的数据水平增长时，面板栏也随之增长!

这是我的代码，我已经把所有的控件水平对齐拉伸，但没有效果: 
    <UserControl.Resources>
    <DataTemplate x:Key="ContentTemplate">
        <ScrollViewer HorizontalAlignment="Stretch"
                      HorizontalScrollBarVisibility="Auto" 
                      VerticalScrollBarVisibility="Disabled" 
                      VerticalAlignment="Top"> 
            <ItemsControl x:Name="Test" 
                          ItemsSource="{Binding Items}"
                          HorizontalAlignment="Stretch">
                <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <toolkit:WrapPanel Orientation="Vertical" 
                                           Height="220"
                                           HorizontalAlignment="Stretch">
                        </toolkit:WrapPanel>
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
                <ItemsControl.ItemTemplate>
                    <DataTemplate>
                        <controls:ParameterItem Style="{StaticResource ParamItem}"  
                                                Description="{Binding Code}" 
                                                ParamValue="{Binding Value}"/>
                    </DataTemplate>
                </ItemsControl.ItemTemplate>
            </ItemsControl>
        </ScrollViewer>
    </DataTemplate>
</UserControl.Resources>
<Grid x:Name="LayoutRoot" Background="White">
  <telerik:RadBusyIndicator IsBusy="{Binding IsLoading}">
    <Grid Grid.Column="1">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
        </Grid.RowDefinitions>
        <Grid HorizontalAlignment="Stretch" Height="28">
            <Grid.ColumnDefinitions>
                <ColumnDefinition />
                <ColumnDefinition Width="90" />
            </Grid.ColumnDefinitions>
            <Grid.Background>
                <ImageBrush ImageSource="/ISDN.NSS.UI.Themes;component/Images/HeaderBG.png" />
            </Grid.Background>
            <TextBlock Grid.Column="0" FontSize="13" FontWeight="Bold" VerticalAlignment="Center" FontFamily="Arial" Margin="8,0,0,0" Text="Model Parameters"></TextBlock>
        </Grid>
            <telerik:RadPanelBar Grid.Row="1" 
                                 Margin="2" 
                                 ItemsSource="{Binding Parameters}"
                                 HorizontalAlignment="Stretch"
                                 >
                <telerik:RadPanelBar.ItemTemplate>
                    <telerik:HierarchicalDataTemplate ItemTemplate="{StaticResource ContentTemplate}" 
                                                      ItemsSource="{Binding RootItems}">
                        <TextBlock Text="{Binding Name}" FontSize="13" FontWeight="Bold" FontFamily="Arial"/>
                    </telerik:HierarchicalDataTemplate>
                </telerik:RadPanelBar.ItemTemplate>
            </telerik:RadPanelBar>
        </Grid>
    </telerik:RadBusyIndicator>
</Grid>

有人能帮忙吗?

HorizontalAlignment Issue

在Telerik Team的支持下解决了这个问题。下面是编辑后的RadPanelBar模板的代码:

<telerik:Office_BlackTheme x:Key="Theme" />
<SolidColorBrush x:Key="ControlForeground_Normal" Color="#FF000000" />
<Style x:Key="RadPanelBarStyle" TargetType="telerik:RadPanelBar">
    <Setter Property="ExpandMode" Value="Single" />
    <Setter Property="UseLayoutRounding" Value="True" />
    <Setter Property="TabNavigation" Value="Once" />
    <Setter Property="ItemsPanel">
        <Setter.Value>
            <ItemsPanelTemplate>
                <telerik:PanelBarPanel />
            </ItemsPanelTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="telerik:RadPanelBar">

默认scrollviewer必须从RadPanelBar默认样式中移除
