i have a NextGrid with 3 Rows, 1 Text-Col, 1 Image-Col and 4 CheckBox-Cols. The 4 Checkbox Cols are invisible.
I drag a row of the NextGrid and drop it on a Memo Component. Works fine.
After this, i click on one of the col headers to sort the NextGrid. Then i get the attachted error - somithing with
aRow = -1.
In this list you are not allowed to move rows, i used the StartDrag - EndDrag function.
Where is my mistake ?
