Hi Stefan Stoyanov

Great example. That was really helpful to me!

I do have one question though. Is it possible to remove the headers from the "book-items". I have some "recursive" data that I want to display with the same headers for all rows.

Is this possible and if so, how?

I wasn't able to use x:Key="master", only Key="master". I get the following exception when I try to build.

'Initialization of 'Infragistics.Windows.DataPresenter.XamDataGrid' threw an exception.' Line number '34' and line position '14'.

The exception refers to the first instance of <igDP:XamDataGrid.FieldLayouts>.

<igDP:XamDataGrid x:Name="MyGrid" DataSource="{Binding Calculations}" AssigningFieldLayoutToItem="MyGrid_AssigningFieldLayoutToItem">
            <igDP:XamDataGrid.FieldSettings>

Hello again,

It seems like I am missing something. Would you please send me an isolated sample project, so I will be able to investigate your issue further.

Looking forward for your reply.

Hi Stefan

I actually got the XamDataGrid working with the XAML from my previous post, I just had to simplify the code-behind. I do have a couple of questions though...

Is it possible to remove the indentation, so all the "sub-columns" align with the top-level?

I would also like to know if it is possible to bind the XamDataGrid to an MVVM model instead of using the <Grid.DataContext> XAML-tag?

I would like to be able to set the DataContext of the MainWindow-class to an instance of a class (vmMain) that exposes an ObservableCollection...

Hello Christian,

I attached a sample project showing the functionalities that you are looking for. Please let me know if this meets all your requirements or you need further assistance on this matter.

Looking forward for your reply.

Hi Stefan,

I saw your sample - this is the functionality I need also.

In my case i have generic data and I use AutoGenerateFields = True; What could I do in this case? How to override the LabelPresenter and DataRecordPresenter styles only for the ChildRecords?

Looking forward to your suggestion,

George

Hello George,

The approach I suggested you works if there are different FieldLayouts for the parent and child records, so I created a sample project for you, which works with self-reference data.

Hope this helps you.

Hi Stefan,

are you sure, this style applies always to the first level? In my case I have only one FieldLayout and it IsDefault.

So by me it applies to all the levels.

Is there any other Property, that one could use for triggering?

Greets,

George

Hello George,

I can suggest you use the following Styles for the LabelPresenter and DataRecordPresenter:

<Style TargetType="{x:Type igDP:LabelPresenter}">
    <Style.Triggers>
        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Self},Path=Field.Owner.IsDefault}" Value="False">
            <!--Add the Setters for the LabelPresenter-->
        </DataTrigger>
    </Style.Triggers>
</Style>
<Style TargetType="{x:Type igDP:DataRecordPresenter}">
    <Style.Triggers>
        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Self},Path=FieldLayout.IsDefault}" Value="False">
            <!--Add the Setters for the DataRecordPresenter-->
        </DataTrigger>
    </Style.Triggers>
</Style>

Which has Triggers in order to determine if the Labels and Records are from the first level or not.

Hope this helps you.
