Event Data

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

Property	Description
Column	Gets the column index of the cell with the editor that raised the event.
EditingControl	Gets the Control object that raises the event.
Row	Gets the row index of the cell with the editor that raised the event.
View	Gets the view that contains the cell with the editor that raised the event.

Remarks

This event is raised by the OnComboCloseUp method when the list portion of the combo box cell closes (after the user selects an item from the combo box list).

You can use this event to make changes to a list (such as adding or removing items) after the user has selected an item. This event is raised after the ComboSelChange event.

For more details on the individual event arguments, refer to EditorNotifyEventArgs members.

Example

This example raises several of the combo box related events when the user clicks on a combo box button and makes a selection from the list.

FarPoint.Win.Spread.CellType.ComboBoxCellType cb = new FarPoint.Win.Spread.CellType.ComboBoxCellType();
fpSpread1.ActiveSheet.Cells[0, 0].CellType = cb;

private void fpSpread1_ComboCloseUp(object sender, FarPoint.Win.Spread.EditorNotifyEventArgs e)
{
     ListBox1.Items.Add("ComboCloseUp event fired");
}

private void fpSpread1_ComboDropDown(object sender, FarPoint.Win.Spread.EditorNotifyEventArgs e)
{
     ListBox1.Items.Add("ComboDropDown event fired");
}

private void fpSpread1_ComboSelChange(object sender, FarPoint.Win.Spread.EditorNotifyEventArgs e)
{
     ListBox1.Items.Add("ComboSelChange event fired");
}

Visual Basic

Dim cb As New FarPoint.Win.Spread.CellType.ComboBoxCellType()
FpSpread1.ActiveSheet.Cells(0, 0).CellType = cb

Private Sub FpSpread1_ComboCloseUp(ByVal sender As Object, ByVal e As FarPoint.Win.Spread.EditorNotifyEventArgs) Handles FpSpread1.ComboCloseUp
     ListBox1.Items.Add("ComboCloseUp event fired")
