Hello,
I've upgraded an old wpf application to latest Telerik WPF control version... before I've defined a GridViewCommandRow that will substitute the grouping header to the 2 buttons export/print

the code is taken from a your article and it's

public class GridViewCommandRow

{

public static readonly DependencyProperty IsEnabledProperty =

DependencyProperty.RegisterAttached("IsEnabled",

typeof (bool),

typeof (GridViewCommandRow),

new PropertyMetadata(false, OnIsEnabledChanged));

public GridViewCommandRow(RadGridView grid)

{

RadGridView = grid;

CommandRow = new ContentControl();

CommandRow.SetValue(Grid.RowProperty, 0);

if (ViewCommandTemplate == null)

{

var commandRowTemplate = Generic.GetInstance()["CommandRowTemplate"] as ControlTemplate;

if (commandRowTemplate != null)

ViewCommandTemplate = commandRowTemplate;

}

public ControlTemplate ViewCommandTemplate { get; set; }

private ContentControl CommandRow { get; set; }

public RadGridView RadGridView { get; private set; }

public static void SetIsEnabled(DependencyObject dependencyObject, bool enabled)

{

dependencyObject.SetValue(IsEnabledProperty, enabled);

}

public static object GetIsEnabled(DependencyObject dependencyObject)

{

return dependencyObject.GetValue(IsEnabledProperty);

}

private static void OnIsEnabledChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)

{

var radGridView = sender as RadGridView;

if (radGridView != null)

{

if ((bool) e.NewValue)

{

// Create new GridViewCommandRow and attach RadGridView events.

var commandRow = new GridViewCommandRow(radGridView);

commandRow.Attach();

}

private void Attach()

{

RadGridView.DataLoaded += RadGridView_DataLoaded;

}

private void RadGridView_DataLoaded(object sender, EventArgs e)

{

if (RadGridView.Items.Count > 0)

{

RadGridView.SelectedItem = RadGridView.Items[0];

}

Grid hierarchyGrid =

RadGridView.ChildrenOfType<Grid>().FirstOrDefault(c => c.Name == "HierrarchyBackground");

if (hierarchyGrid != null && CommandRow.Parent == null)

{

hierarchyGrid.Children.Add(CommandRow);

CommandRow.Template = ViewCommandTemplate;

}

The template is defined here

Hello,

Indeed, there is no Name "HierrarchyBackground" of the Grid element presented any more. You will have to change your code similar to:

Grid hierarchyGrid = RadGridView.ChildrenOfType<Grid>().FirstOrDefault();

if (hierarchyGrid != null && CommandRow.Parent == null)

{

hierarchyGrid.Children.Add(CommandRow);

CommandRow.Template = ViewCommandTemplate;

}

I hope this helps.
