Splitting one column into multiple

Hi everyone,

 

I have a normal pageblock table in my page. It shows data in a single column. I also do have checkbox bound to them.

 

For eg : original OP :

[]A
[]B

[]C

[]E

[] F

And desired one is :

 

[]A    []B      [] C
[]E   []F

 

 

 

 

Thanx and eagards,

Shailesh Patil

There's probably a few ways to do this, the way I'd approach it is to put the items into a wrapper class that contains up to three instances of your object. 

 

e.g. controller

 

public MyController
{
   public List<MyWrapper> myWrappers{get; set;}

   public class MyWrapper
   {
      public Account myAcc1 {get; set;}
      public Account myAcc2 {get; set;}
      public Account myAcc3 {get; set;}

      public Boolean checkbox1 {get; set;}
      public Boolean checkbox2 {get; set;}
      public Boolean checkbox3 {get; set;}
   }

   public MyController()
   {
      myWrappers=new List<MyWrapper>();
      Integer idx=0;
      MyWrapper wrap;
      
      for (Account acc: [select id, Name from Account limit 12])
      {
         if (0==Math.mod(idx, 3))
         {
            wrap=new MyWrapper();
            wrap.myAcc1=acc;
         }
         if (1==Math.mod(idx, 3)
         {
            wrap.myAcc2=acc;
         }
         else if (2==Math.mod(idx, 3)
         {
            wrap.myAcc3=acc;
         }
      }
   }
  
}

 Page:

<apex:pageBlockTable value="{!MyWrappers}" var="wrap">
   <apex:column headerValue="Col 1">
      <apex:outputField value="{!wrap.myacc1.Name}"/>
      <apex:inputCheckBox value="{!wrap.checkbox1}"/>
   </apex:column>
   <apex:column headerValue="Col 2">
      <apex:outputField value="{!wrap.myacc2.Name}"/>
      <apex:inputCheckBox value="{!wrap.checkbox2}"/>
   </apex:column>
   <apex:column headerValue="Col 1">
      <apex:outputField value="{!wrap.myacc3.Name}"/>
      <apex:inputCheckBox value="{!wrap.checkbox3}"/>
   </apex:column>
</apex:pageBlockTable>

 

Not compiled, but hopefully you get the drift.

Can you show me another way?

I reckon this could be achieved with dynamic visualforce bindings, storing the information in maps containing lists.  It would end up being a much more complex solution to maintain though.  Wrapper classes is always my preferred solution.

I think you need to increment idx....right?

Correct.  First typo of many no doubt!

Hi Bob

Could you please share the total code to split the one column into 3 columns (As mentioned above)?

 
bob_buzzardbob_buzzard

I don't have any code that does it via dynamic bindings I'm afraid.  As I mentioned above, I always use wrapper classes unless I have no option, as it makes it easier for those that come after me to maintain.

Hi Bob,

Thanx a lot. That worked !

 

Now can you guide me on another issue?

How can I pass the checkbox values and update the corresponding variable in the class? Note that one can select multiple checkboxes.
bob_buzzardbob_buzzard

You don't need to do anything further to update the value in the class, as the checkbox is part of the viewstate.

 

I wrote a blog post on this a while ago - that should give you the details:
