memory leak

[alvin chen]

 My syncfusion version is  20.2.0.43. when I closed a tab or all tabs,the memory is not reduced. I went through some of the posts on the forum,but i can not resolve this issue,my code as below:

<syncfusion:TabControlExt x:Name="tab"

                                      Grid.Column="1"

                                      prism:RegionManager.RegionName="ContentRegion"

                                      CloseButtonType="Individual"

                                      CloseMode="Delete"

                                      OnCloseButtonClick="Tab_OnCloseButtonClick"

                                      ShowTabListContextMenu="False"

                                      >

                <i:Interaction.Triggers>

                    <i:EventTrigger EventName="OnCloseAllTabs">

                        <i:InvokeCommandAction Command="{Binding DataContext.CloseAllTabs, RelativeSource={RelativeSource AncestorType={x:Type Window}, Mode=FindAncestor}}" />

                    </i:EventTrigger>

                    <i:EventTrigger EventName="OnCloseOtherTabs">

                        <i:InvokeCommandAction Command="{Binding DataContext.CloseOtherTabs, RelativeSource={RelativeSource AncestorType={x:Type Window}, Mode=FindAncestor}}" CommandParameter="{Binding SelectedItem, ElementName=tab}" />

                    </i:EventTrigger>

                </i:Interaction.Triggers>

                <syncfusion:TabControlExt.ItemTemplate>

                    <DataTemplate>

                        <TextBlock Text="{Binding Content.DataContext.Title, RelativeSource={RelativeSource AncestorType={x:Type TabItem}}}" />

                    </DataTemplate>

                </syncfusion:TabControlExt.ItemTemplate>

            </syncfusion:TabControlExt>

private void Tab_OnCloseButtonClick(object sender, Syncfusion.Windows.Tools.Controls.CloseTabEventArgs e)

        {

            var datacontext = this.DataContext as MainWindowViewModel;

            datacontext.close((e.TargetTabItem as ContentControl).Content );

        }

this method will remove view form prism region

  public void close(object obj)

        {

            regionManager.Regions["ContentRegion"].Remove(obj);

        }

I do not know where is the problem,please give me a help,thanks
