Deadlock when updating datasource of hierarchical GridView

Hi

I have a RadGridView with a  object-relational 3-tier-hierarchy where the datasource is a DataSet.

In a situation where my application updates an item of the first sublayer of the dataset:

each.ItemArray = vorgang.ItemArray;

the whole application gets into a deadlock.

Here is the call stack:

Licensing Issue

Good Evening All,

I have recently secured a new Teleik Developer License, and I have updated the controls to the latest version.

When I run my application from within Visual Studio 2022 i am getting an error message displayed across my forms as shown below.

I have clicked on the help button and followed all the steps on the following web link (https://docs.telerik.com/devtools/winforms/licensing/license-key).  I have tried the automatic and the manual installation methods; however, the message is still showing.  I have confirmed that the telerik-license.txt file has been downloaded as well.

Can you please assist with this so I can get the message removed?  

Thank you in advanced.

How does the CheckedDropDownList control use DescriptionTextListDataItems?
I introduced the function that the CheckedDropDownList control can use DescriptionTextListDataItems on https://www.telerik.com/products/winforms/checkeddropdownlist.aspx, but I didn't find any sample code. Only the DropDownList uses DescriptionTextListDataItems. How should the CheckedDropDownList control use DescriptionTextListDataItems?

Implementing multiple filtering with RadCheckedDropDownList
I want to implement quick selection using the RadCheckedDropDownList control. When a user types content (assuming it's "adc" ,"1"or "app"), it should automatically filter to match the first record.

The data source is:
List<Model> datas = new List<Model>
{
new Model { Title = "Apple", Description = "abc1" },
new Model { Title = "Banana", Description = "ffd2" },
new Model { Title = "Cat", Description = "mmd3" },
new Model { Title = "Juice", Description = "nnr5" }
};

I have referred to https://docs.telerik.com/devtools/winforms/controls/dropdown-listcontrol-and-checkeddropdownlist/checkeddropdownlist/populating-with-data/data-binding, and also tried using Filter and FilterExpression, but neither can achieve multiple filtering. How can this be implemented?

ArgumentExceptions and InvalidOperationExceptions when calling RadGridView.EndUpdate()

Hello,

we have an application using Telerik version 2021.3.1123.40. It is not the first time these errors were reportet, but I have no methode to reproduce it at the moment. The chain of Events for both errors is, that RadGridView.FilterChanged-Event is called, from there we call our method "UpdateProzessschritte" (UpdateProcessSteps), which does a BeginUpdate and EndUpdate of the grid. When EndUpdate is called, the 2 errors orccured under certain, unknown conditions.

Do you have any ideas which causes could lead to this exceptions and how to fix it? Or is this a known problem which was already fixed in later versions?
