Hi,
I need a help on using Map on VF page .
public Map<Integer, String> bucketOrderMap{get;set;}
String bucketQuery = 'select Id, Name, Tutorial_Bucket_Unique_Name__c, Sort_Order__c from Tutorial_Bucket_Order__c where Name like \''+ tCategory.getName() +'\'';// and sort_order__c >='+ (currentBucket.sort_order__c - 1) + ' and sort_order__c <= '+currentBucket.sort_order__c + 1 ;
bucketOrderMap = new Map<Integer, String>();
for(Tutorial_Bucket_Order__c curr:Database.query(bucketQuery)) {
bucketOrderMap.put(Integer.valueOf(curr.sort_order__c), curr.Tutorial_Bucket_Unique_Name__c);
}
ON VF=========
<ul>
<apex:repeat value="{!bucketOrderMap}" var="c">
<apex:outputLabel value="{!c.Label}" />
<!-- <li id="buck_{!c.}">{!c.Label}</li> -->
</apex:repeat>
</ul>
In Vf page i got prob. can any body help me how to do it on this withour <apex:pageblock table>

Hello,
As a rule, a map is not sorted. Event though you put the order as the key in a map, it will be traversed randomly only.
If you need to maintain the order, use lists and sort in the soql query itself.
public with sharing class TutorialController { public List<String> bucketOrderList{get;set;} public MarketoTutorialController(ApexPages.StandardController stdController){ article = (Tutorial__kav) stdController.getRecord();bucketOrderList= [select Id, Name, Tutorial_Bucket_Unique_Name__c, Sort_Order__c from Tutorial_Bucket_Order__c where Name =: tCategory.getName() order by Sort_Order__c];
and in VF page
<ul> <apex:repeat value="{!bucketOrderList}" var="c"> <li id="buck_{!c.Tutorial_Bucket_Unique_Name__c}">{!c.Sort_Order__c} {!c.Tutorial_Bucket_Unique_Name__c}</li> </apex:repeat> <!-- <apex:repeat value="{!tCategory.childCategories}" var="c"> <li id="buck_{!c.Name}">{!c.Label}</li> </apex:repeat> --> </ul>This should give you the list sorted. Please make sure of any syntax errors / variable naming errors before running this.
Hope this helps.

Though am not sure what exactly you want to ask. But I have prepared a sample for you, please use this and let me know if it doesn't resolves your problem.
VFP:
<apex:page controller="DisplayMapValue"> <apex:pageBlock > <!-- With PageBlock Tabel --> <apex:pageBlockSection > <apex:pageBlockTable value="{!accMap}" var="val"> <apex:column value="{!accMap[val].Id}"/> </apex:pageBlockTable> </apex:pageBlockSection> <!-- Without PageBlock Tabel --> <apex:pageBlockSection > <apex:repeat value="{!accMap}" var="val"> <apex:outputLabel value="{!accMap[val].Name}"/> </apex:repeat> </apex:pageBlockSection> <!-- Without PageBlock Tabel and Without repeat --> <apex:pageBlockSection > <apex:outputLabel value="{!intMap[1]}"/> </apex:pageBlockSection> </apex:pageBlock> </apex:page>Class :
public class DisplayMapValue { public Map<Id , Account> accMap {get; set;} public Map<Integer , Integer> intMap {get; set;} public DisplayMapValue() { accMap = new Map<Id, Account>([select id , name from account limit 10]) ; intMap = new Map<Integer , Integer>() ; intMap.put(1 , 1) ; intMap.put(2 , 2) ; } }Read the comments on visualforce page.

Thanks For the reply.. But its not solving my prob...
Actualy my prob is .. I created a map as follows..
public with sharing class TutorialController { public Map<Integer, String> bucketOrderMap{get;set;} public MarketoTutorialController(ApexPages.StandardController stdController){ article = (Tutorial__kav) stdController.getRecord(); String bucketQuery = 'select Id, Name, Tutorial_Bucket_Unique_Name__c, Sort_Order__c from Tutorial_Bucket_Order__c where Name like \''+ tCategory.getName() +'\''; bucketOrderMap = new Map<Integer, String>(); for(Tutorial_Bucket_Order__c curr:Database.query(bucketQuery)){ bucketOrderMap.put(Integer.valueOf(curr.sort_order__c), curr.Tutorial_Bucket_Unique_Name__c); }map is giving me the correct value like...
============bucketOrderMap========={1=Manage_Tags, 2=Manage_Channels}
now my prob is how to show these values on a VF page.
<ul> <apex:repeat value="{!bucketOrderMap}" var="c"> <li id="buck_{!c}">{!c}</li> </apex:repeat> <!-- <apex:repeat value="{!tCategory.childCategories}" var="c"> <li id="buck_{!c.Name}">{!c.Label}</li> </apex:repeat> --> </ul>if i run the commented part than it will run ok bt the prob is its not giving me the sorted order of the tutorials..
so because of sorting i used map and know i dnt knw how to use this in VF page...
I hope now i explain myself..
if still have any doubt .. i will explain it more..
Thanks,
Crist
