As of 2024 Q2, we will deprecate .NET Framework 4.0, .NET Framework 4.5, and .NET Core 3.1 distributions. This decision is rooted in our dedication to align with Microsoft’s recommended framework versions so that our products leverage the latest advancements in technology, security, and performance.
We are aligning our product with Microsoft’s lowest-supported framework versions for .NET Framework and .NET, respectively. Please refer to the following blog post:
Product Update for Enhanced Performance and Security (telerik.com)
For more information about how to upgrade your project's .NET Framework version, you can check the following MSDN article:

WPF Chart - Empty Values - Telerik UI for WPF
I have added link for EmptyPointBehaviour for wpf but it's available for windows, I want to implement same for wpf or uwp xaml UI.
Hi,
I use this behavior to manage multiple selection on radgridview (with selection mode = "extended" and with GridViewSelectColumn)
It works but when I try to initialize the selection with some items at the end of initialization I receive the OnSelectionChanged that remove all the elements selected but the first.
public class GridViewMultiSelect : Behavior<RadGridView>
{
protected override void OnAttached()
{
base.OnAttached();
AssociatedObject.DataContextChanged += OnDataContextChanged;
AssociatedObject.SelectedItems.CollectionChanged += OnSelectedItemsChanged;
AssociatedObject.SelectionChanging += OnSelectionChanged;
AssociatedObject.Items.CollectionChanged += OnItemsChanged;
}
private void OnSelectionChanged(object? sender, SelectionChangingEventArgs e)
{
}
private void OnItemsChanged(object? sender, NotifyCollectionChangedEventArgs e)
{
}
private void Select(IEnumerable<NsMisuraViewWithType> misure)
{
foreach (var item in misure)
{
AssociatedObject.SelectedItems.Add(item);
}
}
private void OnDataContextChanged(object? sender, DependencyPropertyChangedEventArgs e)
{
if (AssociatedObject.DataContext is LoadedMeasurmentsVM viewModel)
{
viewModel.SelectAction = Select;
SetSelectMeasurements();
}
}
private void SetSelectMeasurements()
{
if (AssociatedObject.DataContext is LoadedMeasurmentsVM viewModel)
{
foreach (var item in AssociatedObject.SelectedItems)
{
if (viewModel.SelectedMeasurements.All(m => m.Misura.Id != ((NsMisuraViewWithType)item).Misura.Id))
{
viewModel.SelectedMeasurements.Add((NsMisuraViewWithType)item);
}
}
}
}
private void OnSelectedItemsChanged(object? sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
SetSelectMeasurements();
}
protected override void OnDetaching()
{
base.OnDetaching();
AssociatedObject.DataContextChanged -= OnDataContextChanged;
AssociatedObject.SelectedItems.CollectionChanged -= OnSelectedItemsChanged;
}
}
Hi,
in my project there is one RadGridView is present. Inside it there is GridViewComboBoxColumn but whenver I am selecting other item from that comboboxcell, binded property setter is not being called and as a result datacontext also remains same.
But whenever cell of that combobox column loses the focus property setter is called and as a result datacontext is fixed.
So, I found one workaround that is I added UpdateSourceTrigger=PropertyChanged property for my DataMemberBinding like below:
DataMemberBinding="{Binding ****, UpdateSourceTrigger=PropertyChanged}"
So it started working whenever I am selecting other item from that comboboxcell, binded property setter is being called and as a result datacontext also updated.
But the issue is that whenever comboboxcell loses its focus then again binded property setter is called the second time, which I don't want.
public class CustomKeyboardCommandProvider : DefaultKeyboardCommandProvider
{
private GridViewDataControl parentGrid;
public CustomKeyboardCommandProvider(GridViewDataControl grid)
: base(grid)
{
this.parentGrid = grid;
}
public override IEnumerable<ICommand> ProvideCommandsForKey(Key key)
{
List<ICommand> commandsToExecute = base.ProvideCommandsForKey(key).ToList();
if (key == Key.Enter)
{
commandsToExecute.Clear();
commandsToExecute.Add(RadGridViewCommands.CommitEdit);
commandsToExecute.Add(RadGridViewCommands.BeginInsert);
commandsToExecute.Add(RadGridViewCommands.CommitEdit);
this.parentGrid.ChildrenOfType<GridViewScrollViewer>().First().ScrollToEnd();
}
return commandsToExecute;
}
}
