The RadGrid control supports building your own custom column editors. These are ideal if you want to customize your users' editing experience.
A custom column editor has to inherit from one of the base editor classes, our example will inherit from GridTextColumnEditor. The two most important methods that have to be overriden are AddControlsToContainer and LoadControlsFromContainer. The former has to create the editor's controls and add them to the container's controls collection. The latter extracts information from the container's controls:
Protected Overrides Sub AddControlsToContainer()
picker = New RadDatePicker
picker.ID = "editPicker"
ContainerControl.Controls.Add(picker)
End Sub
Protected Overrides Sub LoadControlsFromContainer()
picker = ContainerControl.Controls(0)
End Sub
The tricky part is to remember to set an ID to all controls that you create. This is generally a good ASP.NET programming practice and can save you a lot of hunting for postback events not being fired and viewstate not being loaded.
