Hello,
How to add a data in the 2nd column of my DesktopListbox (hierarchical with Checkboxes). I set the “Column Count” property to 2).
Thanks,

Me.AddRowAt(Me.RowCount, "Name") //col 1
//Add (Me.RowCount, Str(NumItems) + " items") //col 2 ???
Me.RowTagAt(Me.LastAddedRowIndex) = "yyyy"
2 
Me.cellTextAt(Me.LastAddedRowIndex, 1)=Str(NumItems)+ " items"
3

This adds “Name” to col 0 (not 1) of a new row.

Antonio beat me to it for the answer.
