Dynamic Fields on VF page

Hi,

 

Suppose I have the list of fields of an Object using:

 

Map<String, Schema.SObjectField> FMap = Schema.SObjectType.CustomObject__c.fields.getMap();

CustomObject__c tempRecord=new CustomObject__c();

List<String> mainList=new List<String>();

Set<String> tempSet=FMap.keySet();

for(String s:tempSet)

mainList.add(s);

 

Now, Can you show all these fields on the VF page in Input mode ?

 

In other words, assume the first field is Text, so I should get <apex:inputText>. At present, we can assume that all fields are text.

what can be possible VF code. I was thinking something with the repeat tag.

Hey,

 

You can use dynamic components. So creating the controls in the controller and applying the fields to the controls you need.

 

A basic example is below:

 

=====================
Visualforce page
============================

<apex:page standardcontroller="YourController" extensions="DynamicComponentExample">
    <apex:form >
           <apex:dynamicComponent componentValue="{!pageBlock}"/>
    </apex:form>
</apex:page>


Controller:
=============

public Component.Apex.PageBlock getpageBlock(){

        Component.Apex.PageBlock pb=new Component.Apex.PageBlock();
        Component.Apex.PageBlockTable  ptable=new Component.Apex.PageBlockTable();

        Component.Apex.Repeat repeat= new Component.Apex.Repeat( var = 'f');
        repeat.expressions.value='{!mainList}';

        Component.Apex.OutputField oppTotal = new Component.Apex.OutputField();
        oppTotal.expressions.value='{!CustomObject__c[f]}';
        repeat.childComponents.add(oppTotal);

        ptable.childcomponents.add(repeat);
        pb.childcomponents.add(repeat);

        return pb;
    }

 

Something along these lines should work. Its hard to give a complete answer without more code.

Hi,

 

Yes you are right. Try that in repeat tag

<apex:repeat value="{!mainList}" var="ml" >

<table>

<tr>
<td style="width:95px;border-bottom:1px solid #E3DEB8;">

<apex:inputText value="{!ml}" style="width: 95px;"/>

</td>

</tr>

</table>

</apex:repeat>

 

If this post solves your problem , please mark it as solution.

 

Thanks
