[Gambas-user] TableView Problem

[nando]

To count the _DATA events, do (similar to) the following.

Create a label called Label_Count
with TEXT as 0 (zero)

The first code line inside the _Data event for the TableView..
Label_Count.Text = Label_Count.Text + 1

... now scroll and/or click on your TableView.

Watch the count

Also, notice how the Label is a static control.
It's implementation is opposite to your comment.
