Load RadDataGrid with closed grouping header

[aben]

When the page loads all group headers are collapsed and the list of items below them are shown. Is there an option to load the page with the group headers closed and items under them hidden.

<Grid>
    <telerikGrid:RadDataGrid AutoGenerateColumns="False"
                             UserEditMode="Cell"
                             x:Name="grid">
        <telerikGrid:RadDataGrid.Columns>
            <telerikGrid:RadDataGrid.GroupDescriptors>
                <common:PropertyGroupDescriptor PropertyName="HeaderName"/>
            </telerikGrid:RadDataGrid.GroupDescriptors>

            <telerikGrid:DataGridTemplateColumn>
                <telerikGrid:DataGridTemplateColumn.CellContentTemplate>
                    <DataTemplate>
                        <Label Text="{Binding ItemName}" />
                    </DataTemplate>
                </telerikGrid:DataGridTemplateColumn.CellContentTemplate>
            </telerikGrid:DataGridTemplateColumn>

        </telerikGrid:RadDataGrid.Columns>
    </telerikGrid:RadDataGrid>
</Grid>

Hi Aben,

Indeed, currently all the groups of the DataGrid are expanded by default.  We've already been working on exposing some methods for collapsing and expanding certain or all groups  - hopefully this functionality will be included in the upcoming official release (R1 2018).

I have created a feature request item in our feedback portal, you could subscribe to it and receive notifications for status changes at the following link:
DataGrid: Add support for expanding/collapsing groups programatically

Let me know if I can assist with anything else.
