Hi

Ive looked at the examples and am unable to get the ExpandAllHierarchyItems working.

Xaml is

<telerik:RadGridView

HorizontalAlignment="Left"

VerticalAlignment="Top"

x:Name="mainListGrid"

ItemsSource="{Binding VillagePrices, Mode=TwoWay}"

AutoGenerateColumns="False"

Width="1140"

Height="520"

AutoExpandGroups="True"

AlternationCount="2"

AlternateRowBackground="#FFF5F5F5"

FontSize="10"

DataLoadMode="Asynchronous"

EnableColumnVirtualization="True"

EnableRowVirtualization="True"

RowIndicatorVisibility="Collapsed"

ShowGroupPanel="False"

IsFilteringAllowed="False"

CanUserFreezeColumns="False"

ShowColumnFooters="False"

CanUserReorderColumns="True"

IsSynchronizedWithCurrentItem="False"

DataLoading="RadGridView1_DataLoading"

Code behind is

private void RadGridView1_DataLoading(object sender, Telerik.Windows.Controls.GridView.GridViewDataLoadingEventArgs e)

{

var dataControl = (GridViewDataControl)sender;

if (dataControl.ParentRow != null)

{

dataControl.Loaded -= dataControl_Loaded;

dataControl.Loaded += dataControl_Loaded;

}

void dataControl_Loaded(object sender, RoutedEventArgs e)

{

((GridViewDataControl)sender).ExpandAllHierarchyItems();

}

Joe
