Hello, Hengky,

The CurrentRow.Index property gives the index of the current row in the active view. According to the provided information, it is not clear how exactly you add a new row. If you use the new row you can use the UserAddedRow event. This event fires when the user has finished adding a new row and the row is successfully added to the grid. In this event, you have access to the Row.Index.

Private Sub RadGridView1_UserAddedRow(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
    Dim index As Integer = e.Row.Index
End Sub

Here is another example, if you add a new row on a button click:

Private Sub radButton1_Click(ByVal sender As Object, ByVal e As EventArgs)
    radGridView1.Rows.Add(2, "Davolio", "Nancy", "Table", 1)
    Dim index = Me.radGridView1.CurrentRow.Index
End Sub

RadGridView offers the CurrentRowChanged event as well. It fires when the current row has changed. Here you have access to the old row and the new current row. Feel free to use it if it is suitable for you.

Private Sub RadGridView1_CurrentRowChanged(ByVal sender As Object, ByVal e As CurrentRowChangedEventArgs)
    Dim currentRowIndex = e.CurrentRow.Index
    Dim oldRowIndex = e.OldRow.Index
End Sub

If the suggested solutions, however, do not help you I would kindly ask you to provide more information or code snippet how exactly you add rows in your grid.

I hope this information is useful. Let me know if I can assist you further.

Hello, Hengky,

Note, if you have a GridViewTextBoxColumn and GridViewCommandColumn in RadGridView and you use the new row to add a new record to the grid when you click on the new row it is normal the RadGridView1.CurrentRow.Index is -1. The row index for the GridViewNewRowInfo is -1 by default, to differentiate it from the other rows in the grid.

When you finalize editing the new row and commit it to the grid's rows collection, eg. by pressing Enter, then the row index of the newly added record changes, and this is expected behavior. 

I attached a test project. Could you please refer to it and let me know if it differs from your set up.

Hai Nadya
finally i found the solution for my self 
just simple code 
    Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
        If baris = -1 Then
            RadGridView1.Rows.Add("baru")
        Else
            RadGridView1.Rows(baris).Cells(0).Value = RadTextBox1.Text
        End If
end sub

Hi, Hengky,

I am glad that you found a suitable solution for your case. According to the provided code snippet, it seems that you update the cell value in a data row. Checking if the row index is -1 is a valid approach if would like to update a cell value in a current data row. 

Do not hesitate to contact us in case of further difficulties.
