Infragistics XamDataGrid Group By on load in WPF

Question

How can I set a Group By on Load for a given property for the XamDataGrid from Infragistics, and making the view of this uncollapsed with the ability to collapse the group disabled? If this is possible I would know how I can hide the Group By small button as well.

My environment is WPF and C#.

So you are able to achieve this by using ListCollectionView and add GroupDescriptions into it and apply ListCollectionView as item source it will generate group with column name which is defined in GroupDescriptions. — Vishal Parekh

Try this,

In Xaml,

<igDP:XamDataGrid x:Name="xdgSample" DataSource="{Binding SampleCollection}" InitializeRecord="xdgSample_InitializeRecord">
                                <igDP:XamDataGrid.FieldLayouts>
                                    <igDP:FieldLayout>     
                                        <igDP:Field Name="field1" Label="Field1"/>
                                        <igDP:Field Name="field2" Label="Field2"/>
                                        <igDP:Field Name="field3" Label="Field3"/>
                                        <igDP:Field Name="field4" Label="Field4"/>
                                        <igDP:Field Name="field5" Label="Field5"/>                                   
                                    </igDP:FieldLayout>
                                </igDP:XamDataGrid.FieldLayouts>
                                <igDP:XamDataGrid.FieldLayoutSettings>
                                    <igDP:FieldLayoutSettings AllowFieldMoving="No" 
                                                      AllowDelete="False"
                                                      AutoGenerateFields="False" 
                                                      AutoFitMode="ExtendLastField"
                                                      SelectionTypeRecord="Single" 
                                                      FilterUIType="LabelIcons"
                            GroupByExpansionIndicatorVisibility="Collapsed">
                                    </igDP:FieldLayoutSettings>
                                </igDP:XamDataGrid.FieldLayoutSettings>
                            </igDP:XamDataGrid>

In codebehind,

Private ObservableCollection<SampleBO> sampleCollection;

Public ObservableCollection<SampleBO> SampleCollection
{
    get
    {
        return this.sampleCollection;
    }   
}

You can put below code to load and grouping data in Window Loaded event or Constructor,

this.sampleCollection = your collection/List;
this.OnPropertyChange("SampleCollection");

this.xdgSample.FieldLayouts[0].SortedFields.Add(new FieldSortDescription
                        {
                            IsGroupBy = true,
                            Field = this.xamInputList.FieldLayouts[0].Fields["field2"],
                            Direction = System.ComponentModel.ListSortDirection.Ascending
                        });

                        this.xdgSample.FieldLayoutSettings.HeaderPlacement = HeaderPlacement.OnTopOnly;
                        this.xdgSample.FieldLayoutSettings.HeaderPlacementInGroupBy = HeaderPlacementInGroupBy.WithDataRecords;

Also,for expanded groups,use below event,it's for expanding group initially.

private void xdgSample_InitializeRecord(object sender, Infragistics.Windows.DataPresenter.Events.InitializeRecordEventArgs e)    
{    
if (e.Record.NestingDepth == 0)    
{    
    e.Record.IsExpanded = true;    
}    
}
