Alex, You are right about the freezing headers in 9.2v. It works fine to me after upgrading to 9.2.

My biggest problem is grouping and sorting is not working in the following code. Can you please help me to fix this?

 <AcpUINS:AcpXamDataPresenter KeyboardNavigation.TabNavigation="Continue" KeyboardNavigation.AcceptsReturn="True" Grid.Row="1" x:Name="ZoneChannelAssignmentList">

Sorry, I clicked several times post button.

I am not completely sure where the problem might be coming from. One place that I would look is inside the ControlTemplate and check if is correctly defined. If the sorting and grouping does not work only with the custom control template, please give us the style for the CellValuePresenter so that we can look into it.

Here is the control template. Please somebody answer how fix "In Xamdatapresenter sorting and grouping is not working"

<Style TargetType="{x:Type igcontrols:CellValuePresenter}" x:Key="ZnChanCfgChannelsTopDisplayChannel_A19774CellStyle">
      <Setter Property="Template">

We find the problem, which is binding. If I use direct binding like below, Then it is working

<igcontrols:UnboundField Name="Zone Name" x:Name="tEST" BindingPath="Zone.ZnChanCfgZoneZoneName_A9724" BindingMode="OneWay"
              Visibility="{Binding Source={StaticResource GetFeatureNode},
                                Path=Zone.ZnChanCfgZoneZoneName_A9724_Visible,
                                Converter={StaticResource BooleanToVisibility}}">

But if I use CellValuePresenterStyle like below, It is not working

<igcontrols:UnboundField Name="Zone Name" x:Name="tEST" BindingPath="Zone" BindingMode="OneWay"
              Visibility="{Binding Source={StaticResource GetFeatureNode},
                                Path=Zone.ZnChanCfgZoneZoneName_A9724_Visible,
                                Converter={StaticResource BooleanToVisibility}}">
          <igcontrols:Field.Settings>
        <igcontrols:FieldSettings CellValuePresenterStyle="{StaticResource ZnChanCfgZoneZoneName_A9724CellStyle}"/>
       </igcontrols:Field.Settings>
      </igcontrols:UnboundField>
