Formatting data in Apex and returning to VF

Hi :

 

I have a Apex controller which returns List<Task>. This object has 4 product columns which needs to be formatted in the visualforce page which is rendered as pdf. Here is the code for Apex class followed by Visualforce page.

 

How can I format the 4 product fields into a comma separated single field and return it to visual force, the reason being 

Product_Alts__c, Products_Equity__c, Products_Fixed_Income__c, Products_Multi_Asset__c will not always have values. So before returning I would like to format it, now number of records returned can be 1 or greater or 0 depending on the query condition.

 

 

I have not copied the entire code since it is long, but proper variable reference exist in the code.

public List<Task> CallReportData = new List<Task>();

    public List<Task> getCallReportData(){
    
            CallReportData = [select Id, OwnerId, AccountId, Activity_Type__c, Date__c, Location__c, CreatedById, 
                                Contacts__c,Employees__c,Description, Comments__c, Product_Alts__c, Products_Equity__c, 
                                Products_Fixed_Income__c, Products_Multi_Asset__c, Asset_Class_Formula__c 
                                from Task 
                                where (Date__c >= :From_Date and Date__c <= :To_Date)
                                and Type__c = 'Call Report'
                                order by Owner.Name, Date__c];

            return CallReportData;

    }

 

Visual force page.

 

<apex:page controller="GenerateCallReportController" renderAs="pdf">

    <apex:pageBlock >
        <apex:pageblockTable value="{!CallReportData}" var="task">


            <apex:column breakBefore="true" style="vertical-align:Top;height:20">
                <apex:outputText value="Products:" style="font-weight:bold; font-family:Tahoma; font-size:x-small; color:#002C52; width:10%; height:20px"/>
            </apex:column>            

            <apex:column value="{!task.Product_Alts__c}" style="font-weight:normal; font-family:Tahoma; font-size:x-small; width:45%; height:20px"/>            
            <apex:column breakBefore="true" style="vertical-align:Top;height:20"/>
            <apex:column value="{!task.Products_Equity__c}" style="font-weight:normal; font-family:Tahoma; font-size:x-small; width:45%; height:20px"/>
            <apex:column breakBefore="true" style="vertical-align:Top;height:20"/>
            <apex:column value="{!task.Products_Fixed_Income__c}" style="font-weight:normal; font-family:Tahoma; font-size:x-small; width:45%; height:20px"/>
            <apex:column breakBefore="true" style="vertical-align:Top;height:20"/>
            <apex:column value="{!task.Products_Multi_Asset__c}" style="font-weight:normal; font-family:Tahoma; font-size:x-small; width:45%; height:20px"/>








        </apex:pageblockTable>
    </apex:pageBlock>
</apex:page>

I have been able to achieve what you suggested as follows:

 

<apex:column value="{!task.Product_Alts__c},{!task.Products_Equity__c},{!task.Products_Multi_Asset__c},{!task.Products_Fixed_Income__c}" style="font-weight:normal; font-family:Tahoma; font-size:x-small; width:45%; height:20px"/>

 So far so good, only problem is that if there are no values even then commas exist. If somehow I can remove that it will be complete.

Is there any reason why you can't do this client side, i.e. simply render the fields with commas in between?  If not, I think you'll need to create a wrapper class that contains a task and the concatenated string and returns a list of those for the page to render.

Thanks for your reply, I do not have any problem doing it on the client side, but I do not know how to format it. For example, if I do this I am getting an error

 

            <apex:column value="{!task.Product_Alts__c + !task.Products_Equity__c}" style="font-weight:normal; font-family:Tahoma; font-size:x-small; width:45%; height:20px"/>

 

Error:

=======

Error: Incorrect parameter for function 'not()'. Expected Boolean, received Text

 

if you could let me know the exact syntax it would be great.

You'll need to use outputpanels and only render the field and commas if there are values present.
