Hello Stefan,

My XAML-code looks like this:

<igDP:XamDataGrid

                        x:Name="IgGridProjects"

                        DataSource="{Binding Projects2}"

                        ActiveDataItem="{Binding CurrentProjListItem}"

                        SelectedItemsChanged="IgGridProjects_SelectedItemsChanged"

                        AssigningFieldLayoutToItem="IgGridProjects_AssigningFieldLayoutToItem"

                        GroupByAreaLocation="None">

                            <igDP:XamDataGrid.FieldLayouts>

                                <igDP:FieldLayout Key="masterRow">

                                    <igDP:Field Name="ShortName" Label="Short Name" />

                                    <igDP:Field Name="Name" Label="Name" />

                                    <igDP:Field Name="Owner" Label="Owner" />

                                </igDP:FieldLayout>

                                <igDP:FieldLayout Key="nestedRow">

                                    <igDP:Field Name="Name" Label="Name" />

                                    <igDP:Field Name="VersCreateDate" Label="Created On" />

                                    <igDP:Field Name="VersUpdateDate" Label="Updated On" />

                                </igDP:FieldLayout>

                            </igDP:XamDataGrid.FieldLayouts>

                        </igDP:XamDataGrid>

Where should I place the XAML you provided?

Hello again

The objects I'm displaying in the XamDataGrid have multiple public collections. How can I specify which collection should be used for "nested" items in a hierarchical XamDataGrid?

Hello again,

You can set the AutoGenerateFields property of the nested FieldLayout  to False and define the Fields that you want to be displayed.

Isn't that the same as my previous question?

What I want to do here, is to specify the collection from which the nested items should be taken.

For example I have a vmProject ViewModel-class, that I use in my XamDataGrid. This class has two public collections, "Versions" and "Notes". In the XamDataGrid I only want to display objects from "Versions" as child-elements of vmProject. As of now the Grid displays both collections!

I still want the AutoGenerateFields set to false so that I can specify the columns myself.

Hello again,

I apologize for the misunderstanding. I created a sample project for you with the functionality you want. My custom class has two collections, too and I define the FiledLayout, so that only one of them is shown. When you have hierarchical data you should define a Field with the name of the collection or if you have DataSet, with the relationship, when the AutoGenereateFields property is set to False.

Looking forward for your reply.

Thanks. That worked great!

Another question. Is it possible to set some kind of "auto-width" on one of the fields? For example, the Name-field would be dynamic, so that the grid "fills" the window..

Hello Christian,

In your case the records you show as children are not directly children, and they are from the child collection and this is why they don’t have indentation. If you want you can create a style for set the DataRecordPresenter and set its Margin Property. I modified your sample from the previous post and attached it.

Hello Stefan

Apparently the indentation of nested items is removed when setting AutoGenerateFields to false.

How can I keep the indentation but still define my own fields?

No need for that!

I discovered what my problem was. I had removed a piece of XAML that for obvious reasons shouldn't be removed...

Sorry for the inconvenience...
