Binds the data source to the ASPxComboBox control.
This method binds data from the data source to the ASPxComboBox control.
If the "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control" exception appears, use the ASPxAutoCompleteBoxBase.DataBindItems method instead of the DataBind method. Note that the DataBinding event is not raised in this case. For more details, see the Binding to Data topic.
