DateTimePicker和文本框的错误提供程序

Question

我正在Windows窗体上运行应用程序，在其中进行记录，但请确认是否填写了某些字段。但是，我使用的是错误提供程序，但是当我引起错误时，它们将我标记为所有人，除了DateTimePicker和必须在其中输入的文本框输入Int我的代码可以出现什么错误？

private void btnCargar_Click(object sender, EventArgs e)
{

   // Method to clear the error provider (if they had already appeared before)
    LimpiarErrorICono();
    if (txtSalesOrderI.Text == string.Empty || txtModelo.Text == string.Empty || txtCustomer.Text == string.Empty || txtTotalI.Text == string.Empty || cmbPriorityI.Text == string.Empty
        || cmbPriorityStatus.Text == string.Empty || dtmpDateReceived.Checked)  
    {
        this.MensajeError("Faltan Ingresar Datos");

        if (txtSalesOrderI.Text == string.Empty)
        {
            ErrorIcono.SetError(txtSalesOrderI, "Ingrese un SalesOrder");
        }

        if (txtCustomer.Text == string.Empty)
        {
            ErrorIcono.SetError(txtCustomer, "Ingrese un Customer");
        }

        if(txtModelo.Text == string.Empty)
        {
            ErrorIcono.SetError(txtModelo, "Ingrese un Modelo");
        }


          // In this field it is the text box that an int must go and I don't see 
            the error provider when I don't enter anything
        if(txtTotalI.Text == string.Empty)
        {
            ErrorIcono.SetError(txtTotalI, "Ingrese un Numero");
        }

        if(cmbPriorityI.Text == string.Empty)
        {
            ErrorIcono.SetError(cmbPriorityI, "Ingrese una Prioridad");
        }

        if (cmbPriorityStatus.Text == string.Empty)
        {
            ErrorIcono.SetError(cmbPriorityStatus, "Ingrese una Estatus");
        }


        // DateTimePicker in which I must check a date and if the error should not appear icon
        if (dtmpDateReceived.Checked == false)
        {
            ErrorIcono.SetError(dtmpDateReceived, "Ingrese una Fecha");
        }

    }

要确定在文本框中输入的文本是否为int类型，可以使用方法Int32.TryParse。
