Event Data

The event handler receives an argument of type CellEventArgs containing data related to this event. The following CellEventArgs properties provide information specific to this event.

PropertyDescription
Cell Returns a reference to the cell of interest.
Remarks

The cell argument returns a reference to an UltraGridCell object that can be used to set properties of, and invoke methods on, the cell that had an item selected. You can use this reference to access any of the returned cell's properties or methods.

This event is generated when an item is selected from the cell's dropdown list. A dropdown list item is considered selected when the user clicks it or highlights it when navigating the list using navigation keys.

This event is only generated for a cell whose column's Style property is set to 4 (StyleDropDown), 5 (StyleDropDownList), 6 (StyleDropDownValidate), or 8 (StyleDropDownCalendar).

Example
Following code shows some of the information available in CellListSelect event.
