Hello Prashant, 

Why do you have 2 output panels -  
<apex:outputPanel id="ajaxrequest">
     <apex:outputPanel  rendered="{!isRendered}" >
      <apex:inputField value="{!Datavis_Client__c.Others_data__c}" />
      </apex:outputPanel>
</apex:outputPanel>
You can merge into one - 
Try this instead - 
<apex:outputPanel id="ajaxrequest" rendered="{!isRendered}">
       <apex:inputText value="{!Datavis_Client__c.Others_data__c}"  />
 </apex:outputPanel>
In the controller -  
public PageReference  showOrHideInputBox() {        
	Set<String> strSet = new Set<String>(MPItems);
    isRendered = (strSet.contains('OTHERS')) ? true : false;    
}
Let me know, if it helps you


Thanks,
Sumit Kumar Singh

Hello Prashant,
I can't see any action attribute in Action support. 
<apex:actionSupport event="onclick" action="{!showOrHideCheckbox}" reRender="ajaxrequest"/>
In the controller - 
//You can define a boolean variable - 
public boolean isRendered{get;set;}
//Assign default value in the constructor, 'reportController' is the name of constructor
public reportController(){
   isRendered = false;
} 
public void showOrHideCheckbox() {
     isRendered = (MPOptions=='OTHER') ? true : false;    
}
Update the output panel like this - 
<apex:outputPanel id="ajaxrequest" rendered="{!isRendered}">
<apex:inputField value="{!Datavis_Client__c.Others_data__c}" />
</apex:outputPanel>
Hope, this will help you.


Thanks,

Hello Prashant, 
You can use <apex:actionRegion> to over come this - 
Have a look at this -
