Hi friend,

i have created an visualforce page where i have used <apex:inputFile /> to take any CSV file as input

then i am displaying that CSV file's data into the same vf page in tabular format...

but i want that selected CSV's data should be displayed in another vf page. (so by setting attribute renderas="pdf" i can view CSV's data in a PDF format)

how can i do this?

here is my code...

<apex:page controller="uploadCSVcontroller">
  <apex:form >
  <apex:pageMessages id="pm"/>
  <apex:inputFile value="{!contentFile}" filename="{!nameFile}"/>
  <apex:commandButton value="Display" id="theButton"/>  
  
  
  
  <apex:pageBlock >
  <apex:outputPanel id="results">
  <p>nameFile: {!nameFile}</p>
  <p>rowCount: {!rowCount}</p>
  <p>colCount: {!colCount}</p>
    <table title="CSV Output" border="1" width="100%">
       <apex:repeat value="{!results}" var="row">
           <tr>
               <apex:repeat value="{!row}" var="cell">
                   <td> {!cell} </td>
               </apex:repeat>
           </tr>
       </apex:repeat>
     </table>
  </apex:outputPanel>
  </apex:pageBlock>
  </apex:form>
</apex:page>
