Hello Stefan, 

Just add AutoGenerateFieds = false to your sample and you will notice the issue.

My requirement is to bind multi-level tree to the Xamdatagrid. I have nested Observable collection of objects of same class which I need to bind to XamDataGrid.

Previously it was giving me multiple headers for parents child rows with only 2 levels of tree therefore I tried using your solution but it doesn't work if I set AutoGeneraeFields property to false.

Using two field layouts for parent child like below(adding ChildList field in both parent-child layouts) seems to work fine, but in that case second column in my xamgrid is not aligned for Parents-child rows. 

<igDP:XamDataGrid.FieldLayouts>
<igDP:FieldLayout Key="GLAccounts">
<igDP:FieldLayout.Settings>
<igDP:FieldLayoutSettings SelectionTypeCell="Single" SelectionTypeRecord="Single" LabelLocation="Default" AutoGenerateFields="False" ExpansionIndicatorDisplayMode="CheckOnDisplay" />
</igDP:FieldLayout.Settings>
<igDP:FieldLayout.Fields>
<igDP:Field Name="ReferenceAndName" Label="GL Accounts" PropertyChanged="Field_PropertyChanged">
<igDP:Field.Settings>
<uc:RMFieldSettings CellValuePresenterStyle="{StaticResource cvpSubAccount}" />
</igDP:Field.Settings>
</igDP:Field>
<igDP:Field Name="GLAccountMappedAccountID" Label="Mapped Accounts" PropertyChanged="Field_PropertyChanged">
<igDP:Field.Settings>
<uc:RMFieldSettings AllowEdit="True" EditorStyle="{StaticResource xceMappedAccounts}" EditorType="{x:Type igEditors:XamComboEditor}" />
</igDP:Field.Settings>
</igDP:Field>
<igDP:Field Name="SubAccountsList" />
</igDP:FieldLayout.Fields>
</igDP:FieldLayout>
<igDP:FieldLayout Key="SubAccounts">
<igDP:FieldLayout.Settings>
<igDP:FieldLayoutSettings SelectionTypeCell="Single" SelectionTypeRecord="Single" LabelLocation="Hidden" AutoGenerateFields="False" ExpansionIndicatorDisplayMode="CheckOnDisplay" />
</igDP:FieldLayout.Settings>
<igDP:FieldLayout.Fields>
<igDP:Field Name="ReferenceAndName" Label="GL Accounts" PropertyChanged="Field_PropertyChanged">
<igDP:Field.Settings>
<uc:RMFieldSettings CellValuePresenterStyle="{StaticResource cvpSubAccount}" />
</igDP:Field.Settings>
</igDP:Field>
<igDP:Field Name="GLAccountMappedAccountID" Label="Mapped Accounts" PropertyChanged="Field_PropertyChanged">
<igDP:Field.Settings>
<uc:RMFieldSettings AllowEdit="True" EditorStyle="{StaticResource xceMappedAccounts}" EditorType="{x:Type igEditors:XamComboEditor}" />
</igDP:Field.Settings>
</igDP:Field>
<igDP:Field Name="SubAccountsList" />
</igDP:FieldLayout.Fields>
</igDP:FieldLayout>-->
</igDP:XamDataGrid.FieldLayouts>

Can you please tell me why it is not working

Thanks,

Priya

Hello Priya,

I have been looking into your post, but it seems like that I am missing something in your scenario, so if this is still an issue for you, could you please send an isolated sample project, where the issue is reproduced, so I can investigate it further for you.

Looking forward for your reply.

Hello Stefan,

Attached solution does not work if I set FieldLayoutSettings' AutoGenerateFields to 'false'.

If I make make AUtogenerate = 'false' then I am unable to generate tree deeper than 2 levels that is only one child is shown for each parent.

Please help. It is urgent.

Thanks,

Priya

Can they also implement this as a properly working feature for money?

> You can also suggest this feature as new Product idea here:

I have done so, but I don't need it in 10 years but rather in near future.
