从15063更改为目标版本17314后，我的GUI控件是否有任何已知原因发生变化？

Question

我的应用程序使用透视菜单。数据透视表菜单项包含一个用户控件，它是一个页面，因此您单击一个数据透视表项，它会将您带到该数据透视表的详细信息页面，类似于主/明细样式。

我想将我的目标版本升级到版本17134，但是当我这样做时，我会对控件产生一些奇怪的行为。 15063版本中枢轴内的边框根据内容调整其大小。在17134年，它没有根据内容调整它的大小。

我已经尝试在scrollviewer上设置height = auto，这是pivot中内容展示者的持有者。我已经尝试了很多不同的东西，各种控制的高度，但没有运气。任何帮助深表感谢。

这是支点

这是所有页面后面的常规页面模板，它是数据透视表中的内容

<local:BaseControl
    x:Class="LD75ClaimSystem.UI.View.IncomeDetailsView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="using:LD75ClaimSystem.UI.View"
    xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid"
    xmlns:vm="using:LD75ClaimSystem.UI.ViewModel"
    mc:Ignorable="d"
    <StackPanel DataContext="{StaticResource VM}" >
        <Grid Margin="10,0,0,0">
            <Button Content="Add Income"  Margin="0,10,0,0" />
            <ComboBox Header="Claim" Grid.Column="2"/>
        </Grid>
        <grid:RadDataGrid Name="DetailsGrid">
            <grid:RadDataGrid.Columns>

            </grid:RadDataGrid.Columns>
        </grid:RadDataGrid>
    </StackPanel>
</local:BaseControl>

这是预期的行为，以及版本15063的行为。如果我取出网格，边框将调整其大小以适合内容。

这是版本17314的结果。边框不再适应大小，并且似乎受魔法控制，因为它是自己的东西。

更新下载16299的sdk后，意外的行为消失了。目标版本17134仍会导致意外行为。

Answer 1

我不是RadDataGrid的专家，但在我看来这个问题/答案（https://www.telerik.com/forums/raddatagrid-and-scroll-bar），它包含自己的ScrollViewer数据。这意味着你不需要ScrollViewer的Pivot中的DataTemplate。

其次，你的BaseControl中的StackPanel不会告诉包含控件它的高度是什么......因为它会不断扩展以适应内容。所以，在这种情况下，你的RadDataGrid根本没有使用它的ScrollViewer。我希望你的奇怪的高度/边距问题与'ScrollViewer'/'StackPanel'和RadDataGrid的不同版本如何协商各自的尺寸有关。

如果你移除ScrollViewer并用含有两个StackPanel的Grid替换RowDefinitions它可能会消失...一个具有自动高度，第二个具有*高度。

像这样的东西：

       <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Button Content="Add Income"  Margin="10,10,0,0" />
        <ComboBox Header="Claim" HorizontalAlignment="Right" Margin="0,10,10,0"/>
        <grid:RadDataGrid Name="DetailsGrid" Grid.Row="1">
            <grid:RadDataGrid.Columns>

            </grid:RadDataGrid.Columns>
        </grid:RadDataGrid>
    </StackPanel>
