TextBox内存消耗

Question

我有UserControl这是一个项目列表，其中每个项目都包含大量TextBox和TextBlock控件。我尝试禁用撤消步骤，但即使在列表中添加了10个项目，内存消耗也非常高。我尝试运行内存分析工具，我可以看到TextBoxes是大约50 MB内存的最大消费者。

我的XAML如下

<UserControl.Resources>
    <converter:GenericButtonConverter x:Key="ButtonConverter"/>
    <DataTemplate x:Key="RawSendListTemplate">
        <ListBoxItem BorderBrush="LightGray" BorderThickness="0.5" HorizontalAlignment="Stretch" Margin="3,1,3,1">
            <Grid>
                <Grid.ColumnDefinitions>

</Grid>

我需要一些帮助来减少列表项的内存占用。

[UPDATE]

在XAML中添加它可以使应用程序更具响应性

UndoLimit="0" AcceptsReturn="False"  IsUndoEnabled="False"

现在我想知道我还能在哪里获得更多
