I want to freeze a table's header. The table class is derived from XamDataPresenter. How to implement freeze ?
Fixed Fields (aka Frozen Column Headers) will be built in by default in the next release of NetAdvantage for WPF (~Early April).

Thanks for your information!

If I see data records in OnRecordsInViewChanged event while debugging it added only one group instead of adding several. Please see the screen shot
Regarding RecordsInViewChanged event, it will fire for each record which is being scrolled into/out of view.
Regarding the TextBox, this would be because of the ControlTemplate. The CellValuePresenter contains PART elements, which name is important. You can see the default templates in the DefaultStyles directory and see the full template and retemplate it accordingly.
I am still not sure about the headers. By default, they are always on top at all times.
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?

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.
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>

Plaese let me know how to fix sorting and grouping in the above example
As far as I can see, this is a custom/user control inside the cell. You might want to take a look at this blog post by Andrew Smith on how to host elements in the cells of the XamDataGrid:

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