Data Binding .Net 5

[Ignus]

I have a new project and am using .Net 5.0.  I have a RadForm with a RadTreeView control.  I am trying to get a DataSource selected for a RadTreeView control.  I am expecting the UI at this point to give me the option to add a new DataSource but that is not available.  When I manually add a System.Windows.Forms.BindingSource to the form it is also not listed in the available DataSources.  I am running VS 2019 Version 16.9.0 Preview 3.0 and Telerik 2021.1.122.  Is this the correct behavior at this point?

Hello Ignus,

Thank you for writing.

UI for the various data binding scenario is still not available in the Visual Studio designers for .NET Core. It`s not an issue in our implementation but rather a missing feature in the new design-time framework in Visual Studio. Microsoft are currently working on implementing the feature. Once it is available for the standard .NET Core controls it will also be available for the Telerik controls.

For the time being you can consider binding the controls programmatically or setting them up in unbound mode. Here are some relevant documentation articles for the RadTreeView: 

• https://docs.telerik.com/devtools/winforms/controls/treeview/data-binding/unbound-mode
• https://docs.telerik.com/devtools/winforms/controls/treeview/working-with-nodes/adding-and-removing-nodes

I hope this will help. Let me know if you need further assistance.

Regards,
Hristo
