ComboBoxSelectedIndexChanged

The server-side OnComboBoxSelectedIndexChanged event occurs when the user clicks on item in the Combobox, causing a postback.

The event handler function receives two arguments:

1. The RadRibbonBar which has fired the event. This argument is of type object, but can be cast to the RadRibbonBar type.

2. An EventArgs object.This object has a number of properties for handling the request for the items:

   • Index – index of the newly selected item.

   • Item – the newly selected item.

   • DropDown – the DropDown which fired the event.

   • Group – the group in which the DropDown is placed.
