I send objects, message error to return and the validation type. After process the class return a arraylist with messages error case this object don´t is true.
 The class can to be modified to change color object, change text color or other client information.

 I send a project with code how to use this class.

  CheckObjects oCheckObjects = new CheckObjects();
 

2 - Add Object for Analyze

  oCheckObjects.AddObjectForAnalyze(Object,MessageError, TypaValidation);

  oArrayList = oCheckObjects.ProcessAnalyze();

 4 - Show Message Error

         if (oArrayList.Count > 0)
         {
             foreach (String aString in oArrayList)
             {
                 vErrorMensage += " - " + aString + "<A href="file://\\n">\\n</A>";
             }
             ClientScript.RegisterClientScriptBlock(Page.GetType(), "Error", "<script>function MessageError(){\n alert(\"Check Objects below:\\n " + vErrorMensage + "\");\n}</script>");
             Body.Attributes.Add("onload", "MessageError()");
