AfterCellListCloseUp Event

Occurs after a cell's dropdown list has been closed in a column using one of the dropdown list styles.

Syntax

Visual Basic

'Declaration
 
Public Event AfterCellListCloseUp As CellEventHandler

C#

public event CellEventHandler AfterCellListCloseUp

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.

Property	Description
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 its dropdown list closed. You can use this reference to access any of the returned cell's properties or methods.

This event is generated when a cell's dropdown list has been closed, either programmatically, or by user interaction. A cell's dropdown list can be closed programmatically by setting the cell's DroppedDown property to False.

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).

Set the column's ValueList property in order to populate the dropdown list.

The BeforeCellListDropDown event is generated when a cell's dropdown list is dropped down.

Example

Following code prints out the key of the column associated with the cell that closed its drop down.
