Consider the Salary field in the Employee class. A common requirement would be to change the default spin editor with a RadMaskedEditBox in the EditorInitializing event. However, if you follow the steps described here: https://docs.telerik.com/devtools/winforms/controls/datalayout/change-the-editor-to-a-bound-raddropdownlist

the BindingCreating event wouldn't be fired for any editor that is not some of the default ones.

TextPosition label sizing is incorrect. Regardless of AutoSize and AutoSizeLabels settings, only the first label size is calculated correctly. I've attached a project and a screenshot of the issue. It seems size isn't calculated if TextPosition == Telerik.WinControls.UI.LayoutItemTextPosition.Top.
