QlistView problem

[grsandeep85]

Hi ,
I am using Listview for displaying some values but the thing is i have inputed the serial number(1-15) in 1st column and now i need to add the values in 2nd(diameter) and 3rd (length) column is inputed from diameter and length linedits which is present in new dialog.

Now if i enter the values from lineedits it is writing into the listview after the 15th serial number how to overcome this issue. Also i have attached the listview form and addDialog form.
