Layout with children rows - They disappear if there's no children
posted

Hi,

 

We've got a grid with two FieldLayout, the second being a children to the first one.

<DataPresenter:FieldLayout Key="Children" ParentFieldLayoutKey="DefaultLayout" ParentFieldName="Children">

Our bound objects have an IEnumerable property named Children.

The problem happens when the Children collection is null or empty. We assign the DataSource, then we see the rows for an instant and they disappear. By using Snoop we're able to confirm the DataSource is still there with the parent rows.

 

Has anyone seen this before? We're using Infragistics WPF4 v 11.1.20111.2193

 

Thanks.

    Ok, it also does happen if there are child rows.

    Please see below the grid XAML.

     

     

    <DataPresenter:XamDataGrid 

                                        x:Name="_positionsGrid"

                                       Style="{StaticResource DefaultInfragisticsGridStyle}"

     

                                       >

                  <DataPresenter:XamDataGrid.Resources>

                    <Style TargetType="{x:Type DataPresenter:LabelPresenter}" BasedOn="{StaticResource GridLabelPresenter}"/>

                    <Style TargetType="{x:Type ScrollBar}" BasedOn="{StaticResource NuclearScrollBar}"/>

                    <Style TargetType="{x:Type DataPresenter:HeaderPrefixArea}">

                      <Setter Property="Template">
