[vb.net] how to get data from selected row from datagridview

i have a new problem, I have a datagridview, try to see the picture, I want when cells that exist in the datagridview on click, then click on the data entered into textbox1, anyone know how where how? thanks for helping me

I was tried like below, but its not work

Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
        If Me.DataGridView1.RowCount > 0 Then

            TextBox1.Text = Convert.ToString(Me.DataGridView1.SelectedRows)


            'TextBox1.Text = Me.DataGridView1.Rows(Me.DataGridView1.row).Cells(1).Value
        End If
    End Sub

I was having the same issue and this works excellently.

Private Sub DataGridView17_CellFormatting(sender As Object, e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView17.CellFormatting  
  'Display complete contents in tooltip even though column display cuts off part of it.   
  DataGridView17.Rows(e.RowIndex).Cells(e.ColumnIndex).ToolTipText = DataGridView17.Rows(e.RowIndex).Cells(e.ColumnIndex).Value 
End Sub
