Business logic of Require property in Questionnaire Template

<accesscontrol>Main:MyGroup</accesscontrol>

Description

This property existed in both questionnaire template's properties and question's properties .

• Setting for questionnaire :

• Setting for question (non-Grid question)

• Setting for question (Grid question)

• Using in .NET

CatGlobe.Domain.Questionnaires.PropertyType.Required

• Using in Java

Property.REQUIRED

Business logic

Required as Questionnaire's property

• If this property is checked , it means that all the question in the questionnaire template , which are not specified Required property explicitly , will require the users answer it and they can't go to another question without answering .

Behind the code : the template will has property REQUIRED with the property's value is "true" .

• If this property is unchecked , it means that all the question in the questionnaire template , which are not specified Required property explicitly,will not require users answer it.

Behind the code : the template will has property NOT_REQUIRE with the property's value is "true"

Required as Question's property

This property is inherited from the value of property Required in a questionnaire. However, a question can set anew for this property through its Required property, and this value is only applied to this question.

• Inherited from Required property of questionnaire template :

In this case the there is not both REQUIRED and NOT_REQUIRED property register in question's property (the existed one will be removed). So the question will inherited from the Required property of the questionnaire template]

• Required property is checked

In this case , the question will has REQUIRED property with the property's value is "true"

• Required property is unchecked

In this case , the question will has NOT_REQUIRED property with the property's value is "true"

• If the question is a GRID question ( single grid , multi grid , scale grid , text grid) , users need to define which sub questions will be required . The range will be save to the value of correlative property (REQUIRED or NOT_REQUIRED).

Working with Required property in .NET side

This example shows how to use the Required property of grid question and apply it to related sub question

 1             // Apply the required property if set
 2             QuestionProperty requiredProperty = q.GetProperty(PropertyType.Required);
 3             if (requiredProperty != null && !string.IsNullOrEmpty(requiredProperty.Value))
 4             {
 5                // Parse the property's value into ranges
 6                Ranges requiredRanges = new Ranges(requiredProperty.Value);
 7 
 8                // For each range run through the integers contained in the range
 9                // and set the required property to true
10                foreach (Range r in requiredRanges)
11                   for (int j = r.From; j <= r.To; j++)
12                      //Tho : this if expression is to make sure that we only take valid
13                      //sub question index .  Some old questionnaire template has invalid property value
14                      if ( j>-1 && j < q.subQuestions.Count)
15                         q.subQuestions[j].Required = true;
16             }
17 
18             // Apply the not required property if set
19             QuestionProperty notRequiredProperty = q.GetProperty(PropertyType.NotRequired);
20             if (notRequiredProperty != null && !string.IsNullOrEmpty(notRequiredProperty.Value))
21             {
22                // Parse the property's value into ranges
23                Ranges notRequiredRanges = new Ranges(notRequiredProperty.Value);
24 
25                // For each range run through the integers contained in the range
26                // and set the required property to false
27                foreach (Range r in notRequiredRanges)
28                {
29                   if (r.To >= q.SubQuestions.Count)
30                      r.To = q.SubQuestions.Count - 1;
31                   for (int j = r.From; j <= r.To; j++)
32                      //Tho : this if expression is to make sure that we only take valid
33                      //sub question index .  Some old questionnaire template has invalid property value
34                      if (j > -1 && j < q.subQuestions.Count)
35                         q.subQuestions[j].Required = false;
36                }
37             }

This example show how to apply Required property of questionnaire template to question and register it to client side

foreach (QuestionnaireProperty p in Questionnaire.Properties)
{
switch (p.Type)
//Before inherited from Questionnaire properties , you must make sure that the question does not have both Required and NotRequired property
         case PropertyType.Required:
                  if (Question.IsGrid())
                  {
