[Sufvan Adil 2023]

my code

If DataGridView1.Rows.Count - 1 Then

                DataGridView1.Rows.Add()
                    DataGridView1.CurrentCell = DataGridView1.Rows(DataGridView1.Rows.Count - 1).Cells(1)
                    DataGridView1.BeginEdit(True)

            Else
                Exit Sub
                '    DataGridView1.Rows.Add()
            End If

i many code try

            If (DataGridView1.Rows.Count > 0) Then
                For i = 0 To DataGridView1.Rows.Count - 1
                    If DataGridView1.Rows(i).Cells("d1alisname").Value = "" Then

                        Exit Sub
                    Else
                        DataGridView1.Rows.Add()
                    End If
                Next

Thanks to VB's "evil type coercion", that condition will be False if you have precisely one row in your grid. For any other number of rows, that condition will be True.

That code walks through all the rows in your grid until it finds one where the d1alisname column is blank. For every row that it encounters where that column is not blank, it adds a new row. You haven't explained exactly what you're trying to do. At a guess, you want to add a new row if there are either no rows in the grid, or all of the rows have a value in the d1alisname column. In which case, you need to move the "add row" code after your For loop from your second code block:

For i = 0 To DataGridView1.Rows.Count - 1
If DataGridView1.Rows(i).Cells("d1alisname").Value = "" Then
Exit Sub
End If
Next

DataGridView1.Rows.Add()
