Hi Sushma, I have tested this,
  
<apex:page controller="ClassName">
    <apex:form >
        <apex:selectList value="{!choosenObject}" size="1">

              <apex:selectoptions value="{!objects}"/>

        </apex:selectList>


<br/>
       <apex:commandbutton value="Query" action="{!queryMe}" rerender="output"/>

         <apex:dataList id="output" value="{!records}" var="r">
         {!r}
        </apex:dataList>

    </apex:form>

</apex:page>
  
public class ClassName{
       
        public List<SelectOption> objects {get; set;}
        public List<SObject> records {get; set;}
        public string choosenObject {get; set;}
 
        public ClassName(){
               objects = new List<SelectOption>();
               records = new List<SObject>();
               Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe(); 
               List<String> objectList = new List<String>();
               objectList.addAll(gd.keyset());
               Schema.DescribeSobjectResult[] results = Schema.describeSObjects(objectList );
               for(Schema.DescribeSobjectResult res : results) { 
                    if( ! res.isCustom()) 
                          objects.add(new selectOption(res.getName() ,res.getLabel())); 
               }

        }

        public void queryMe(){
               if(string.isNotBlank(choosenObject))
               records = database.query('select Id, Name from '+choosenObject);
               //you may need to remove Name field for some objects
        }
}

Hi Sushma, 
Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe();
List<SelectOption> standardObjects = new List<SelectOption>();
List<String> objectList = new List<String>();
objectList.addAll(gd.keyset());


Schema.DescribeSobjectResult[] results = Schema.describeSObjects(objectList ); 
for(Schema.DescribeSobjectResult res : results) {
if( ! res.isCustom()) 
standardObject.add(new selectOption(res.getName() ,res.
getLabel());

 }

use this select option to generate picklist in visual force page and use dynamic query to return results


Thank you

Hi Sushma,

You can use below code for displaying only standard objects in a picklist.
  
public with sharing class dynamic1cls {
    
     public list<selectoption> lst{get;set;}
     public String Obname { get; set; } 
       public dynamic1cls(){
          List<Schema.SobjectType> lstobj = Schema.getGlobalDescribe().Values();
          lst = new List<selectoption>();
          for(Schema.SobjectType s: lstObj){
             if(!string.valueOf(s).contains('__c')){
                 lst.add(new selectoption(string.valueOf(s),string.valueOf(s)));
             }
         }
        
    }

}
<apex:page controller="dynamic1cls" >
     <apex:form >
         <apex:selectList size="1" value="{!Obname}" style="width:200px">
               <apex:selectOptions value="{!lst}"> 
               </apex:selectOptions>
         </apex:selectList>
     </apex:form>
</apex:page>

Hi Sushma,

You can use below code 
public class DynamicTableController  
    {  
        //List displayed on UI  
        public List<selectoption> supportedObject {get; set;}

              }  
            }  
              
        }

                fieldLableAPI.add(new SelectOption(fieldAPI.getDescribe().getName() , fieldAPI.get
                describe().getLabel())) ;  
                }  
            }  
        }  
        public void ShowTable()  
        {

Thanks.

My requirement is if i select object in picklist, then i have to display the records.

Hi Sushma,

The apex class as follows
  
public class ClassName{
       
        public List<SelectOption> objects {get; set;}
        public List<SObject> records {get; set;}
        public string choosenObject {get; set;}
 
        public ClassName(){
               objects = new List<SelectOption>();
               records = new List<SObject>();
               Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe(); 
               List<String> objectList = new List<String>(); objectList.addAll(gd.keyset());
               Schema.DescribeSobjectResult[] results = Schema.describeSObjects(objectList );
               for(Schema.DescribeSobjectResult res : results) { 
                    if( ! res.isCustom()) 
                          objects.add(new selectOption(res.getName() ,res. getLabel()); 
               }

        }

        public void queryMe(){
               if(string.isNotBlank(choosenObject)
               records = database.query('select Id, Name from '+choosenObject);
               //you may need to remove Name field for some objects
        }

​}

and the Vf page
  
<apex:page controller="ClassName">
    <apex:form>
        <apex:selectList value="{!choosenObject}">

              <apex:selectoptions value="{!objects}">

        </apex:selectList>


<br/>
       <apex:commandbutton value="Query" action="{!queryMe}" rerender="output">

         <apex:dataList id="output" value={!records} var="r">
         {!r}
        </apex:dataList>

    </apex:form>

</apex:page>
You need to accept that every object has different set of coulmns and data types, so you may need use links to go to corresponding object links

like for Account '/001 ' and contact '/003' etc

Hi Chidambar Reddy,

For me no need to go to list view page of any objects. I wants to get all the records from standard objects and to display it in one page and I did upto it.

I dont know how to display the records for particular selected objects in picklist.

Thanks for your support.
Chidambar ReddyChidambar Reddy
I have given the same in the above comment, but it will only dispaly record ids of the selected object and even if you query other fields you can't manage it as a table

Have you tried the above code?

Thanks for your support Chidambar Reddy.

Is there any other way to display the other fields also.
Chidambar ReddyChidambar Reddy
Yes, we can display other fields as well, I can't provide you the solution as it takes a lot of time, but I can provide you the way to solve it

for that you need to select which fields you want to query and use a wrapper to hold the state of selected fields
use dynamic table coulmns that will render based on fields selected

You can get fields of the selected fields by using schema classes 'ObjectName.SobjectType.getDescribe().getFields()' like this.

Apex class:

public class SobjectList{
  public string val {get;set;}
  public string obj{get;set;}
 public String AccountList { get; set; }    
    //Subclass : Wrapper Class 
    public class Accountwrap {
        //Static Variables 
        public string id;
        public string name;
        public string Phone;     
        //Wrapper  Class Controller
        Accountwrap() {
            Phone = '';
        }       
    }      
    //Method to bring the list of Account and Serialize Wrapper Object as JSON
    public  static String getlstAccount() {
        List < Accountwrap > lstwrap = new List < Accountwrap > ();
        List < account > lstacc = [SELECT Id, Name, Phone
                                   FROM Account];                               
        for (Account a: lstacc) {
            Accountwrap awrap = new Accountwrap();
            awrap.id = a.id;
            awrap.name = a.name;
            if (a.Phone != null) {
                awrap.Phone = a.Phone;
            }
            lstwrap.add(awrap);
        }
        return JSON.serialize(lstwrap);
     }
}

can u do the modification of using schema class in it.

Thanks.
