[RadGridView] Add sort column under the Header Row

Hi all,

As mentioned in the subject, I am creating an application displaying the data into the user. Beside the original sorting methods, I have to add an extra column under the Header Row as for the user types in with keywords.

The first pic will explain it further.

WPF telerik:RadComboBox set SelectedItem not working

Hi All,
I'm trying the different ways to Set the SelectedItem to WPF telerik:RadComboBox after load the data and this is still showing the default option empty.
I'm loading the data from my ViewModel (MVVM). Any ideas?

<telerik:RadComboBox x:Name="ActionList" DisplayMemberPath="Name" Grid.Column="1" Grid.Row="0"
                                         ItemsSource="{Binding ActionList, UpdateSourceTrigger=PropertyChanged}"
                                         SelectedItem="{Binding SelectedAction, Mode=TwoWay}"
                                         IsEditable="True" IsReadOnly="True" telerik:TextSearch.TextPath="Name"
                                         MinWidth="120" />
View Model:
private ActionModel _selectedAction;
public AtionModel SelectedAction
{
get { return _selectedAction; }
set { _selectedAction = value; NotifyOfPropertyChange(() => SelectedAction); }
}

RadGridView: Columns overlap after changing DisplayIndex and IsVisible per Binding

Hi!

I have a RadGridView with multiple "templates" that change the order and visibility of columns by Binding. It works fine for the first time but when I change it again this happens:

I use Databinding to change DisplayIndex and IsVisible of every column like this:

DisplayIndex="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.TableConfiguration.ExampleColumnIndex, FallbackValue=6, Mode=TwoWay, NotifyOnSourceUpdated=True}"

Any ideas? Thank you!

RadListBox bound to RadDataFilter DragDrop

Hi,
I use two RadListboxes to allow users to order some things and save the ordered list.
I now want the user to filter the lists and tried the RadDataFilter.
So I bound the Listboxes Itemsource to the RadFIlter.

The problem is, that now the Drag Dop doesnt work anymore.

Is there any way I can do both? Use the filter and the Drag Drop? Or do I have to program my own filter functionality?

Greetings Benedikt

NotifyIcon not working in demo application

Hello,
I'm using a notifyIcon in my application and it doesn't work, but I saw that also the samples included in "Progress Telerik UI for WPF" don't work.
Maybe there is a windows 10 setting? I look in the settings of tray notification area but I didn't see any setting that can disable the working.

Thank you

Luigi

Error in .NET Core converted project

Hello

I did manually converted a .NET Framework 4.7.2 to .NET Core 5.0. I did the conversion by editing the .csproj files using Sdk format.

I have Telerik WPF libraries (2021.3.914) installed locally, and the project refers to the local DLLs.

I don't get any design-time error. I can even see the preview of the page and controls in the designer.

When I run the app I get a runtime error.

System.TypeInitializationException: 'The type initializer for 'Telerik.Windows.Controls.TelerikLicense' threw an exception.'

MissingMethodException: Method not found: 'System.ActivationContext System.AppDomain.get_ActivationContext()'.

I have two projects running side by side: the .NET Framework 4.7.2 runs fine, .NET Core 5.0 fails.

Thanks

Herald
