The OboutDropDownList control can be configured to enable / disable other controls from the page when the selection is changed. Everything is done internally by the OboutDropDownList control. No extra coding is required.

This example showcases the use of a OboutDropDownList ("Country") that controls two other fields, based on a condition. When "USA" is selected in the "Country" drop down list, the "State" drop down list is enabled and the "Province" text box is disabled. When any other country other than USA is selected in the "Country" drop down list, the "State" drop down list is disabled and the "Province" text box is enabled.

The OboutDropDownList exposes various properties that are used to configure the conditional linking:

ControlsToEnable - gets or sets a value indicating the controls that will be enabled when some specific items are selected.
EnablingValues - gets or sets a value indicating the comma separated item values that will be used by the ControlsToEnable property.
ControlsToDisable - gets or sets a value indicating the controls that will be disabled when some specific items are selected.
DisablingValues - gets or sets a value indicating the comma separated item values that will be used by the ControlsToDisable property.
