How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then

How To Add, Delete And Update Database Using Datagridview
View 5 RepliesI'm trying to get the Update button and my Delete button to work. Please advice me accordingly on what I'm doing wrongly. And as for the delete button, I have little clue of doing it.

The user could edit the records directly at the DGV and when the Update button is clicked, both DGV and database gets updated.
