Hi Nishad,

Here are the steps for it.

1. Generate standars object and their corresponding fields in list of options dynamically in your controller.
2. Upon selection of object name and ,call your controller method to frame dynamic query.(Take care for each object's fields)
3. Execute query and display result.

Let us know if it helps you.

Hi nishad basha 7

Hi Ashish 

<apex:selectList value="{!selectedSobject}" multiselect="false" size="1" >
<apex:selectOption itemValue="Account" itemLabel="Accounts"/>
 <apex:selectOption itemValue="Contact" itemLabel="Contacts"/>
<apex:selectOption itemValue="Opportunity" itemLabel="Opportunity"/>
</apex:selectList>
Don't Use This tag


U can Use 

<apex:inputText value="{!searchKeyword}" action = {!serch}/> when press the button then display the records
 
Ashish_Sharma_DEVSFDCAshish_Sharma_DEVSFDC
Hi,

Sure we can use inputSelect in above case ,but you have to enter object name correctly everytime.
so better to use picklist.

Hope this helps.

In This Code I want tothrow the custome error and ine more thing here i want to dispaly case records also...... plz solve the problem
Keyur ModiKeyur Modi

Hi SS,
FOr the custom error you can use <apex:pageMessage> tag and for the case object record you need to change the string  Query.Because Name Filed is not there in case.

string Query=''; Query='SELECT id,CaseNumber FROM '+ selectedSobject; system.debug('==Query=='+Query);

still if you found any dificulty then feel free to ask.
