Question

我的DataGrid有隐藏的列。如果我在“取消隐藏”列之前尝试水平滚动到表的末尾，则会出现以下错误。有人可以帮忙吗？

这是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说这个问题已在最新的更新中得到解决。我从NuGet下载了它，它确实解决了这个问题。

使用隐藏列滚动RadDataGrid会引发错误
