Question

排序，过滤，分组，分页时，我遇到以下内存问题：

我打开任务管理器来监控我的应用程序的内存，在加载所有数据（比如500列90列）后，应用程序的内存大小就像150mb，然后每次重复一个动作（我尝试重新排序任何列）记忆增加，增加，增加和永远不会释放

我尝试了与示例相同的测试用例，并在加载了一些内存后，GC释放了未使用的内存。

Plesae帮助，我会提供任何提示。

代码

<telerik:RadGridView Name="dataGrid" Margin="4" Grid.Row="3" ItemsSource="{Binding Items}" IsReadOnly="True" SelectionMode="Extended" AlternationCount="2" AlternateRowBackground="LightGray" FrozenColumnCount="{Binding FrozenColumnIndex}" AutoGenerateColumns="False" RowIndicatorVisibility="Collapsed"  view:GridViewHeaderMenu.IsEnabled="True" SelectedItem="{Binding SelectedItem, Mode=TwoWay}">
