Dynamic Binding : When Object Name is Dynamic Also

Hi,

In earlier post we talked about dynamic binding with field set in this object name was static and fields were coming dynamically from Field Sets.Now we will talk about other way when both Object and Fields are dynamic.

Now we will take examples where object name and fields both are dynamic and fields are not coming from Field Sets either.

Controller Class

public class DynamicBinding {
    
    public sObject sObjectToBind {get;set;}
    public List<String> listObjectFields {get;set;}
        
    public DynamicBinding()
    {
        listObjectFields =  new List<String>();
        Map<String , Schema.SObjectType> globalDescription = Schema.getGlobalDescribe();
        //In this example I have hard coded the object name
        Schema.sObjectType sObjType = globalDescription.get('Account');
        
        sObjectToBind = sObjType.newSObject();
        Schema.DescribeSObjectResult r1 = sObjType.getDescribe();
        
        Map<String , Schema.SObjectField> mapFieldList = r1.fields.getMap();
        Integer i = 0;
        for(Schema.SObjectField field : mapFieldList.values())
            {
                Schema.DescribeFieldResult fieldResult = field.getDescribe();
                if(fieldResult.isAccessible() && fieldResult.isUpdateable())
                    {
                        listObjectFields.add(fieldResult.getName());
                    }
                if(i == 5)
                    break;
                
                i++;
            }
                        
    }
}

Visulaforce Page

<apex:page controller="DynamicBinding">
  
   <apex:form>
       <apex:pageBlock title="Without Field Set Use">
       <apex:pageBlockSection title="Dynamic Object">
           <apex:repeat value="{!listObjectFields}" var="fieldAPIName">
               <apex:inputField value="{!sObjectToBind[fieldAPIName]}"/>
           </apex:repeat>
       </apex:pageBlockSection>
       </apex:pageBlock>
   </apex:form>


</apex:page>

So in above example I used an sObject instance and showed 5 fields only of that Object type. In above example I used Account object you can decide any object pass the name from any parameter or get as input from User using Picklist.
