滚动带有隐藏列的 RadDataGrid 会抛出错误

Question

我的 DataGrid 有隐藏的列。如果我尝试在 "unhide" 列之前水平滚动到 table 的末尾，我会收到以下错误。有人可以帮忙吗？

这里是 XAML:

<tg:RadDataGrid>
<tg:RadDataGrid.Columns>
    <tg:DataGridTextColumn PropertyName="Number"
                                     Header="Number"
                                     SizeMode="Auto"/>
    <tg:DataGridTextColumn PropertyName="BaseText"
                                     Header="Base Text"
                                     SizeMode="Fixed"
                                     Width="300"
                           IsVisible="{Binding IsChecked,                      ElementName=ShowBaseCheckbox,Mode=TwoWay}">
    </tg:DataGridTextColumn>

</tg:RadDataGrid.Columns>
</tg:RadDataGrid>

Telerik 表示此问题已在最新更新中得到解决。我已经从 NuGet 下载了它，它似乎确实解决了问题。
