Use Try - Catch in your controller and create a message in catch block and add to the page. You will also need to have the <apex:pageMessages> component on your page to display the custom messages you create.

ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'Error: Please enter search criteria.');
ApexPages.addMessage(myMsg);

eg.
try{
//your code goes here
}
catch (Exception e){
ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR, 'Error: Please enter search criteria.');
ApexPages.addMessage(myMsg);
}

Hi, Jayant

how to display the custom error message using visualforce? please give me the example of that scenario.
 
JayantJayant
Error: Please enter search criteria. This is the error message that you will see on your VF page with Salesforce styling instead of the actual Exception message (that you caught).
 
ApexPages.Severity.ERROR. This enum will show it either as a Warning, Info or Error.

catch (Exception e){
ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR, 'Error: Please enter search criteria.');
ApexPages.addMessage(myMsg);
}


If you do not want to create a message in the Controller, you may also use <apex:pageMessage> on the Page and define the message their itself. You may use a variable to decide whether this message is rendered or not.

Hi nishad basha 7,
We have one alternate.
Steps
Step 1: In vf page,First use required = false for that required field so that custom error messages will be displayed.
Step 2: Use sample code below to make that field required
 <apex:outputPanel layout="block" style="float: left">
          <apex:outputPanel >
                <div class="requiredInput"><div class="requiredBlock"/>
                      <apex:inputField value="{!acc.name}" required="false" />          
                </div>
          </apex:outputPanel>                              
   </apex:outputPanel>

Go through the example in the link below.Hope it helps you.
