How to prevent duplicate items in a listview?
Posted on 2014-01-23
I have a listview where the user can insert data via an input-form.
After pressing OK on the inputform the data of the inputform will
be put in a new row in the listview. I have also created a doubleclick
event that when the user doubleclicks on the listview row. The input-
form will appear with the data of the listview row. But its possible
to doubleclick on the listview row twice which opens the input-form
twice also. How can i prevent the user from opening the input-form
Does anyone know the answer, or know an example or show
me the right direction.
