Hi, there. I designed a DataGridView under the name "dgvTarifa" and took a chance on trying Row Validating (tried Validated, CellEnter, CellLeave, RowEnter, RowLeave all count same) event. The purpose of the code is to load the selected values of the respective columns into three textboxes in order to rephrase/revalue those and update them by pressing a button. All works fine every single line of code there's nothing wrong except one logical thing.

When the form loads the RowValidating automatically fires because I have a function that Selects the table from the Database and it fills the DataSet by then attaching it to the datasourse of the "dgvTarifa" table. After setting the datasource of the datagridview, it automatically jumps to the RowValidating event which I DONT WANT TO! It first has to finish the whole function and later when the user enters with mouse or enters/leaves a row this has to be fired.
(eventually already have the CellClick event with the same code below so only RowValidating has to work properly...)

Here's the code I use at row validating
Code:
Private Sub dgvTarifa_RowValidating(sender As System.Object, e As System.Windows.Forms.DataGridViewCellCancelEventArgs) Handles dgvTarifa.RowValidating
        If e.RowIndex < 0 Then
            Exit Sub
        Else
            lblID.Text = Me.dgvTarifa.Rows(e.RowIndex).Cells("TariffID").Value
            txtCName.Text = dgvTarifa.Rows(e.RowIndex).Cells("CountryName").Value.ToString
            txtCCode.Text = dgvTarifa.Rows(e.RowIndex).Cells("CountryCode").Value.ToString
            txtCPrice.Text = dgvTarifa.Rows(e.RowIndex).Cells("CountryPrice").Value.ToString
        End If
    End Sub
And this is the Select function of the table which fires at Form_Load of the form:
Code:
 Function SelectTariff()
        Try
            Dim cmd1 As SqlCommand = New SqlCommand("SELECT * FROM SMDR_Tariff ORDER BY TariffID DESC", con) 'Declare cmd1 as SQL Server Command "SELECT" which loads all columns and rows throughout Microsoft SQL Connection "conn".
            Dim ds As New DataSet
            Dim da As New SqlDataAdapter
            da.SelectCommand = cmd1 ' Data Adapter(da) command selection is cmd2, which means selects all cells from the specific table declared above throughout SQL Connection "conn".           
            da.Fill(ds, "SMDR_Tariff") 'Data Adapter(da) fills, adds or refreshes cells or rows in the Data Set(ds).

            Me.dgvTarifa.DataSource = ds.Tables(0) 'Sets MDI Parent(this form) data source of the Data Grid View "dgvTarifa" from the first(0) indexed table of Data Set (ds).
            dgvTarifa.GridColor = Color.DarkSlateGray
            dgvTarifa.CellBorderStyle = DataGridViewCellBorderStyle.None
            dgvTarifa.BackgroundColor = Color.LightGray
            dgvTarifa.DefaultCellStyle.SelectionBackColor = Color.RoyalBlue
            dgvTarifa.DefaultCellStyle.SelectionForeColor = Color.White
            Me.dgvTarifa.DefaultCellStyle.ForeColor = Color.Ivory
            dgvTarifa.DefaultCellStyle.WrapMode = DataGridViewTriState.[True]
            dgvTarifa.SelectionMode = DataGridViewSelectionMode.FullRowSelect
            dgvTarifa.RowsDefaultCellStyle.BackColor = Color.Silver
            dgvTarifa.AlternatingRowsDefaultCellStyle.BackColor = Color.DarkGray
            dgvTarifa.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells
            Me.dgvTarifa.Columns("Delete").DisplayIndex = 4

            Me.ComboBoxFill()
        Catch ex As Exception
            MsgBox(ex.Message & vbCritical) 'Catch exception/s that might occurr anytime by any reason into a simplified message box followed by a critical sign within.
        End Try
        Return 0
    End Function
What are the very best suggestions regarding this issue? Is there any other event I can use instead of the above mentioned. Or how can I stop jumping to this event before the function has been processed to the end?
