我需要展示 Buttons ,用户可以使用它添加控件。按组分类。这是我要的XAML-

<ScrollViewer
    VerticalScrollBarVisibility="Auto">
    <GroupBox
        Name="maingroup"
        Header="Click To Add Controls"
        BorderBrush="Transparent">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition
                    Height="*" />
                <RowDefinition
                    Height="90" />
            </Grid.RowDefinitions>

            <GroupBox
                Grid.Row="0"
                Name="groupVarControls"
                Header="{Binding Path=GroupBoxHeaderText, Mode=OneWay}">
                <ScrollViewer
                    HorizontalScrollBarVisibility="Auto"
                    VerticalScrollBarVisibility="Hidden">
                    <WrapPanel
                        Margin="7,7,0,0"
                        AllowDrop="False">
                        <syncfusion:RibbonButton
                            SizeForm="Large"
                            Name="BarControl"
                            LargeIcon="Images\Bar.png"
                            Label="Bar"
                            AllowDrop="True">
                        </syncfusion:RibbonButton>

                     <!-- 10 More buttons -->

                    </WrapPanel>
                </ScrollViewer>
            </GroupBox>

            <GroupBox
                Grid.Row="1"
                Name="groupVarControls2"
                Visibility="{Binding Path=GroupBoxVisibility, Mode=OneWay}"
                Header="Click to Add control">
                <ScrollViewer
                    VerticalScrollBarVisibility="Hidden"
                    HorizontalScrollBarVisibility="Auto">
                    <WrapPanel
                        Margin="7,7,0,0"
                        AllowDrop="False">
                        <syncfusion:RibbonButton
                            SizeForm="Large"
                            Name="ClockControl"
                            AllowDrop="False"
                            LargeIcon="Images\Clock.png"
                            Label="Clock"
                            Click="ClockControl_Click" />

                      <!-- More buttons -->

                    </WrapPanel>
                </ScrollViewer>
            </GroupBox>
        </Grid>
    </GroupBox>
</ScrollViewer>

我要垂直的 ScrollBar 两者通用 WrapPanel 个人水平 滚动条 的。使用此XAML时,滚动条出现错误, ScrollViewer row (或 column ),并使用 滚动条 马上。

我不能给你一个固定的答案 widht 到 ,因为此控件将显示在 DockPanel (类似于VS工具箱),用户可以使用它。

有什么想法吗?
