Developers should use this method to add a new, dynamically-created TBTextBox to the left-end of the UltraWebToolbar element. The text box's Text property will be initialized to the value given by the text argument.
Use the Insert(Int32,TBObject) method to insert a new instance of TBTextBox before (to the left of) other Toolbar items. When calling Insert, the developer is responsible for creating the TBTextBox instance beforehand, and setting its Text and Key properties afterwards.
