  {

      this.ValidateTextBox(ValidateType.NONE, PostValidate, c =>

                  string.IsNullOrEmpty(c.Text) && c.Tag.Equals("Required"));

  }

  private void PostValidate()

  {

      MessageBox.Show("Field is Required");

  }

``` 





ValidateType.NONE - Indicate that none validate it will be executed



PosValidateAction - The method that will run after validation



c => string.IsNullOrEmpty(c.Text) && c.Tag.Equals("Required") - Condition to validate a TextBox, you can put anything.

[![errorClass.png](https://s13.postimg.org/z0ns3g5jb/error_Class.png)](https://postimg.org/image/yb4zr34zn/)

Then we showed the error in a MessageBox
