Is it possible to differentiate the user selection or programmatically selection of the items in the DropDownList?


Yes, It’s possible to differentiate the selection of items in DropDownList using isInteraction” argument in the select event of DropDownList.


If the value of “isInteraction” is true , then the item has been selected by user interaction. Otherwise it has been selected by properties or methods such as “selectItemByText”, “selectItemByValueor “selectItemByIndicesin the DropDownList.


Initialize the DropDownList as follows



Upon selecting the items in the DropDownList, the client side event “select” will be triggered, in that check whether the value of isInteraction argument is true or not. If the value is true, the item has been selected by user(selected through the mouse hover).
