DataGridView not reflecting current row in RowStateChanged Event

Posted on 2014-10-18

I have a DataGridView that utilizes the RowStateChanged Event. I basically have textboxes that are associated with cells in the DGV. So, when the user uses the arrow key in the DGV depending on what row the cursor is on, that row's data will be reflected in the TextBoxes. For example, for a specific record, there are 4 rows that populate the DGV. In the RowStateChanged Event, I have code that will assign a specific Cell to a TextBox. After the DGV is loaded, I set the CurrentCell to the 1st Cell, 1st Row, however, the TextBoxes reflect data from the last row of data, in this case 4 or 3 if you go by zero index. I ran it thru the debugger and the RowStateChanged Event actually fires first before I set the CurrentCell position.

So, my question is how or where do I set the CurrentCell so the RowStateChanged Event will recognize it's new position?


Here is my code below.

    Private Sub dgvEquipmentItems_RowStateChanged(sender As Object, e As DataGridViewRowStateChangedEventArgs) Handles dgvEquipmentItems.RowStateChanged
            If blnIsLoaded Then
                txtSeqNO.Text = CStr(BL.CheckForNULLs(e.Row.Cells(1).Value))
                txtManufacturer.Text = CStr(BL.CheckForNULLs(e.Row.Cells(3).Value))
                txtComponentSerialNO.Text = CStr(BL.CheckForNULLs(e.Row.Cells(4).Value))
                txtItemNO.Text = CStr(BL.CheckForNULLs(e.Row.Cells(5).Value))
                txtModelNO.Text = CStr(BL.CheckForNULLs(e.Row.Cells(6).Value))
                txtChannel.Text = CStr(BL.CheckForNULLs(e.Row.Cells(8).Value))
                txtCapacity.Text = CStr(BL.CheckForNULLs(e.Row.Cells(11).Value))
                txtCapacityUnit.Text = CStr(BL.CheckForNULLs(e.Row.Cells(13).Value))
                txtLowerRange.Text = CStr(BL.CheckForNULLs(e.Row.Cells(15).Value))
                txtUpperRange.Text = CStr(BL.CheckForNULLs(e.Row.Cells(16).Value))
                txtRangeUnit.Text = CStr(BL.CheckForNULLs(e.Row.Cells(18).Value))
            End If

        Catch ex As Exception
            EH.ErrorMessage = "dgvEquipmentItems_RowStateChanged() - " & ex.Message & "~E"
        End Try

        EH.ProcessMessages(Me, sbr, EH.ErrorMessage)
    End Sub
    Private Sub LoadDetailGrid()
            BL.GetDETAILSEquipmentRecord(iEquipment_ID, dbDETAILS_Equipment, EH)

            dgvEquipmentItems.DataSource = Nothing

            If EH.ErrorMessage = String.Empty Then
                If EH.DataSet.Tables(0).Rows.Count > 0 Then
                    rowCnt = EH.DataSet.Tables(0).Rows.Count
                    dgvEquipmentItems.DataSource = EH.DataSet.Tables(0)
                    dgvEquipmentItems.Columns(0).Visible = False
                    dgvEquipmentItems.Columns(2).Visible = False
                    dgvEquipmentItems.Columns(7).Visible = False
                    dgvEquipmentItems.Columns(9).Visible = False
                    dgvEquipmentItems.Columns(12).Visible = False
                    dgvEquipmentItems.Columns(13).Visible = False
                    dgvEquipmentItems.Columns(17).Visible = False
                    dgvEquipmentItems.Columns(18).Visible = False
                    dgvEquipmentItems.Columns(19).Visible = False
                    dgvEquipmentItems.Columns(20).Visible = False
                    dgvEquipmentItems.Columns(21).Visible = False
                    dgvEquipmentItems.Columns(22).Visible = False
                    dgvEquipmentItems.Columns(23).Visible = False
                    dgvEquipmentItems.Columns(24).Visible = False
                    dgvEquipmentItems.Columns(25).Visible = False
                    dgvEquipmentItems.Columns(26).Visible = False
                    dgvEquipmentItems.Columns(27).Visible = False
                    dgvEquipmentItems.Columns(28).Visible = False
                    dgvEquipmentItems.Columns(29).Visible = False
                    dgvEquipmentItems.CurrentCell = dgvEquipmentItems.Rows(0).Cells(1)
                End If
            End If
    End Sub

RowStateChanged occurs on many different situations. The fact that the row is selected is only one of those. So you are not using the right event for what you want to do if I understand correctly.

Try with RowEnter instead.
