Private Sub Dgv1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles Dgv1.CellContentClick


        Dim cbcImage As DataGridViewImageColumn

        cbcImage = New DataGridViewImageColumn

        Dim cmd As OleDbCommand = Nothing
        Dim sqlDelete As String = ""


        sqlDelete = "DELETE FROM TB_INDATA WHERE ID_IN = '" & Txt_Postid.Text & "'"
        If Txt_Postid.Text = "" Then
            MessageBox.Show("กรุณากรอกข้อมูล", "คำเตือน", MessageBoxButtons.OK, MessageBoxIcon.Information)
            Txt_Postid.Focus()
            Exit Sub


        ElseIf MessageBox.Show("ทำการลบรหัส" & Txt_Postid.Text & " ชื่อ " & Txt_Postname.Text & " ", "คำยืนยัน", MessageBoxButtons.YesNo, MessageBoxIcon.Question) = Windows.Forms.DialogResult.No Then

            Exit Sub
        End If

        Try
            cmd = New OleDbCommand(sqlDelete, OleDbConnection1)
            cmd.ExecuteNonQuery()
        Catch ex As Exception
            MessageBox.Show(ex.Message, "ข้อผิดพลาด", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)

        Finally
            cleargrid()
            ClereAllData()
            Showrecord()



        End Try
    End Sub
