VB.NET-从另一列填充特定列DataGridView

Question

i have 2 DGV name dataListBarang and dataListTransaksi , i'm trying to fill dataListTransaksi spesific column called nama_barang from specific column in dataListBarang called nm_barang

my code so far

Private Sub dataListBarang_CellContentDoubleClick(sender As Object, e As DataGridViewCellEventArgs) Handles dataListBarang.CellContentDoubleClick
        If e.RowIndex >= 0 AndAlso e.ColumnIndex >= 0 Then
            namaBarang = Me.dataListBarang.CurrentRow.Cells(0).Value.ToString
            dataListTransaksi.Columns(1).DataPropertyName = namaBarang
        End If
        dataListBarang.Refresh()
    End Sub

when i double click on DGV dataListBarang , column nama_barang (on dataListTransaksi ) will filled with value from column nm_barang on DGV dataListBarang , but its not working.

please help.

EDIT what i'm trying to do is copy cell from current row when user double click on it then fill the first row on second DataGrid (dataGrid has columns with no data in it) in specific column.

note:

1. see the left dataGrid has data and the right dataGrid is empty
2. see the number!, when user double click, the value from 1 is copied to number 2
3. most of column in right dataGrid is manually input (except Nama Barang) and save to database

Answer 1

What your picture shows is an empty DataGridView on the right. When you copy the cell from the left grid to the cell in the right grid as the picture shows, will have some problems. You will have to “Add” a new row first. Otherwise, subsequent double clicks from the user will simply overwrite the previous double click. The code below checks to see if the double click came from column 0 and if so simply adds a new row to the grid on the right. The value in column 0 is copied to the new row column 1. Hope I am not missing something.

Private Sub dataListBarang_CellContentDoubleClick(sender As Object, e As DataGridViewCellEventArgs) Handles dataListBarang.CellContentDoubleClick
  Dim row As Integer = e.RowIndex
  Dim col As Integer = e.ColumnIndex
  If (col = 0) Then
    dataListTransaksi.Rows.Add("", dataListBarang.Rows(row).Cells(0).Value)
  End If
End Sub

Update: If you do not know which column to copy but you know its name..

Private Sub dataListBarang_CellContentDoubleClick(sender As Object, e As DataGridViewCellEventArgs) Handles dataListBarang.CellContentDoubleClick
  Dim row As Integer = e.RowIndex
  Dim col As Integer = e.ColumnIndex
  If (col = 0) Then
    Dim newRowIndex As Integer = dataListTransaksi.Rows.Add()
    dataListTransaksi.Rows(newRowIndex).Cells("MyColName").Value = dataListBarang.Rows(row).Cells(0).Value
  End If
End Sub

Answer 2

i modified my code based on answer by @JhonG

 Private Sub dataListBarang_CellContentDoubleClick(sender As Object, e As DataGridViewCellEventArgs) Handles dataListBarang.CellContentDoubleClick
        Dim row As Integer = e.RowIndex
        Dim col As Integer = e.ColumnIndex
        namaBarang = Me.dataListBarang.CurrentRow.Cells(0).Value.ToString
        If (col = 0) Then

            If e.RowIndex >= 0 AndAlso e.ColumnIndex >= 0 Then
                dataListTransaksi.Rows.Add("", namaBarang)
                'hargaBarang = Me.dataListBarang
                'Me.dataListTransaksi.CurrentRow.Cells(1).Value = namaBarang
            End If
        End If

when i double click in firstDataGrid it copy the value to another dataGrid and add new row.
