Hi Yavor,
maybe i wasn’t too clear in my previuos message.
Before calling my web service i need to cycle alle the rows on my grid and check if quantity is filled. If quantity isn’t filled in a particular row, i want to show the validation message (that’s because i was using the showvalidationpopup) so the user can insert the missing data. When i add a new row only the quantity cell is not filled because the user have to insert, but the same user could skip quantity insertion so the value of the cell never changes.
I just need to show a message on the cell not validated and when the user start editing the cell i have to hide the message.
That’s it.
The attached image shows what i mean
Validation
