Is there an equivalent of "AfterRowColChange" in Listbox control? 1

[Rajesh Karunakaran]

Hi Friends,

I have a list box whose RowSource is a cursor.
Is there an event in Listbox control equivalent to the "AfterRowColChange" event of a Grid control ?

My requirement is to show the value from the current record in a textbox below the listbox as the user go un and down in the listbox.

Thanks in advance

Hi,

To illustrate Joe's answer, please have a look a the code below

PUBLIC go_Form

go_Form=CREATEOBJECT("clsForm")
go_Form.Visible = .T.
go_Form.Show()

READ Events


CLOSE ALL
CLEAR ALL

The grid has an active row, always one is a current row with the record pointer on it. The listbox has selected items, there can also be none selected or you can have multiselect, those are totally different concepts.

Well, good that InteractiveChange works for your case.
