But for my case, when i create a new appointment for Kent John, i would have to select from the dropdown list and then select a value in this case Kent John from the dropdown list.
You can refer to the Handling FormCreated help topic where in Change the selected index of a resource combobox so always one option is preselected section a similar functionality is shown. Don't forget to add the "res" prefix when search for the resource RadCombobox.
Hope this will help.
