dynamic columns in pageblock table visualforce

hi I have a situation like this : my vf page gets a list of users from the controller.I want to display user information in a pageblock table.number of fields which each user element has is not known,so the number of columns to be displayed in page block table is not known.

 

<apex:pageBlockTable value="{!userList}" var="myUser" id="table">
     <apex:column value="{!myUser.field1}" />
     <apex:column value="{!myUser.field2}" />
     <apex:column value="{!myUser.fieldn}" />
</apex:pageBlockTable>

here the number of fields and their names(field1,field2.......fieldn.....) are to be determined dynamically. I am stuck,any idea will be of great help

 

thanks.

Hi,

 

You can access the field of user object like an array

 

 

Try the below code snippet as reference:

 

<apex:pageBlockTable value="{!objectforquery}" var="displaydata">

        <apex:repeat value="{!fieldapiname}" var="displayfieldname">

        <apex:column value="{!displaydata[displayfieldname]}"/>

        </apex:repeat>

   

    </apex:pageBlockTable>

    </apex:pageBlock>

 

 

Use the below link as reference:

Navatar_DbSup,

 

Thanks for posting this. It did help me in displaying the columns dynamically, but I cannot column header is always blank. 

 

below is snippet of my VF page

 <apex:pageBlock >
   <apex:pageBlockTable value="{!wObjs}" var="wObj"> 
     <!-- Fields -->
     <apex:repeat value="{!wObj.wFields}" var="f">
        <apex:variable value="{!f.name}" var="ColName"/> 
	<apex:column headerValue="TEST">
       	   <apex:inputField value="{!wObj.sObj[f.Name]}" required="true" /> 			        		
	</apex:column>
     </apex:repeat>                     
  </apex:pageBlockTable>
</apex:pageBlock>

I tried with<apex:variable> and hard coded "TEST" too, but nothing seems to work. <inputField> works fine though.

I have spent almost 2 days in getting headerValue populated dynamically, now I give up. 

 

Thank you for your time.
