Hello Soubhagya,

This is a similar kind of requirement and Will help you.



1. Retrieve the objects from the salesforce Org.
Display all the Custom objects with “__C”  names in a picklist field:
page:
=====
<apex:page controller="ObjectRetrieve">
<apex:form >
<apex:outputlabel value="All Objects"/>&nbsp;&nbsp;
<apex:selectList size="1">
<apex:selectoptions value="{!objnames}"></apex:selectoptions>
</apex:selectList>
</apex:form>
</apex:page>
class:
======
public with sharing class ObjectRetrieve {
//Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe();
public List<SelectOption> getobjNames()
{
List<Schema.SObjectType> gd = Schema.getGlobalDescribe().Values();
List<SelectOption> options = new List<SelectOption>();
options.add(new SelectOption('--None','--None--'));
for(Schema.SObjectType f : gd)
{
if(f.getDescribe().getName().contains('__c'))
options.add(new SelectOption(f.getDescribe().getName(),f.getDescribe().getName()));
}
return options;
}
}

Please find the visualforce page and apex class below which solves your requirement.

        entities.sort();
        for(String name : entities)
        {
            objNames.add(new SelectOption(name,name));
        }
        return objNames;
     }

     public List<SelectOption> getObjectFields() 
     {
            Map<String, Schema.SObjectType> schemaMap = Schema.getGlobalDescribe();
            Schema.SObjectType ObjectSchema = schemaMap.get(selectedObject);
            Map<String, Schema.SObjectField> fieldMap = ObjectSchema.getDescribe().fields.getMap();
            List<SelectOption> fieldNames = new List<SelectOption>();
            for (String fieldName: fieldMap.keySet())

i tried this but showing error on controller . 
 
Public objectController1()

        selectedObject = 'account';
    }

ERROR = The property String objnames is referenced by Visualforce Page (object) in salesforce.com. Remove the usage and try again.

Hi Soubhagya,

I think you have created a page with name ObjectRetrieve which is suggested by Mudasir Wani, delete the page and try again. Hope this will solve your issue.
