RadDataLayout: BindingCreating event is not fired when you change the default generated editor

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.

Hello, Matthew,

The possible solution that I can suggest is to add the binding programmatically:

        public RadForm1()

            this.radDataLayout1.EditorInitializing += radDataLayout1_EditorInitializing; 

            this.radDataLayout1.DataSource = new Employee()
                FirstName = "Sarah",
                LastName = "Blake",
                Occupation = "Supplied Manager",
                StartingDate = new DateTime(2005, 04, 12),
                IsMarried = true,
                Salary = 3500,
                Gender = Gender.Female
        RadMaskedEditBox radMaskedEditBox;

        void radDataLayout1_EditorInitializing(object sender, Telerik.WinControls.UI.EditorInitializingEventArgs e)
            if (e.Property.Name == "Salary")
                radMaskedEditBox = new RadMaskedEditBox();
                radMaskedEditBox.DataBindings.Add(new Binding("Value", this.radDataLayout1.DataSource, "Salary",
                    true, DataSourceUpdateMode.OnPropertyChanged));
                radMaskedEditBox.MaskType = MaskType.Numeric;
                radMaskedEditBox.MaskedEditBoxElement.StretchVertically = true;
                e.Editor = radMaskedEditBox;
        private class Employee
            public string FirstName { get; set; }

            public string LastName { get; set; }

            public string Occupation { get; set; }

            public DateTime StartingDate { get; set; }

            public bool IsMarried { get; set; }

            public int Salary { get; set; }

            public Gender Gender { get; set; }

        private enum Gender

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
