Suvra Retrieving Index of a List in Visualforce page
Hi,
Is there any way of accessing the Index of a list on which I am iterating in a page? How to get the current index?
Also, if I have another List object in Controller, and I just want to use that list in a page. Say, i have a list of string called "productList" in Controller and it has values like "A","B","C","D". Now in page I have some index value say,3 available in some variable. And with that index I need to access productList[3]. Is it at all possible in VF?
Thanks in advance,
Suvra
Hey
The only way would be to use an inner class or a list of lists. You need to store the index with the value eg.
public Class myController{
public Class MyClass{
public String value{get;set;}
public Integer index{get;set;}
public MyClass(String v, Integer i){
value = v;
index = i;
}
}
List<MyClass> values{get;set;}
public myController(){
values= new List<MyClass>();
values.add(new MyClass('A',1));
values.add(new MyClass('B',2));
}
Then in the page
<apex:repeat value="{!values}" var="row"> .. etc
You could do something similar with a list of lists but it wouldn't be as readable.
Cheers,

Hi.. Thanks a lot for your reply.
If it is possible that way, then need one more help from you..
Suppose, I have a List of Products "listOfProds" containing Name,Code,Desc columns of Product. Now, depending upon the index value I need to access the element from the List. For example, index = 0; Then I need the 0-th column of List, i.e Name. Is it possible by any chance?? I need to make it dynamic for any column, instead of "listOfproducts[i].Name"
With Best Regards,
Suvra
Hey
Put the list item in the wrapper too then:
public Class MyClass{
public String value{get;set;}
public Integer index{get;set;}
public Product2 product{get;set;}
public MyClass(String v, Integer i,Product2 p){
value = v;
index = i;
product = p;
}
}
<apex:datatable value="{!values}" var="row">
<apex:outputText value="{!row.product.id}"/>
// etc
