How to dynamically add rows in visualforce page

Hi All,

I have a page within which there a button "Add Filter". Beneath this button are some filters like:

 

Select Object(this is a select list containing all salesforce object)---Select Field(this is also a select list containing all fields of salesforce selected salesforce object)------Textbox(this is a textbox)------Remove(this is a button which should remove row).

 

When the user clicks on Add filter, a replica of all above filter items should be added beneath the current filter and on click of Remove button the respective filter should be removed.

 

Any one who as idea/sample code regarding this please help.

Thank you!

 

Regards,

Lakshman

Laksman,

 

 1. Create a wrapper class with the fields, and when page is loaded add one empty object to List<Wrapper>, and bind the same to datatable/pageblock. 

2. When user clicks the "Add" then again create a copy(clone) the wrpper item and add it to the list and bind the table with rerender.

3. if user clicks on delete then you will be having the Index of item in list just remove the same.

try with this code.

<apex:page controller="dynamicController"> 
    
   <apex:form >
       
    <apex:pageblock >
            <br></br>
            <br></br>
        <apex:commandButton value=" Add Row " action="{!AddRecord}" reRender="pb1"/>
            <br></br>
            <br></br>           
            <apex:pageBlockTable id="pb1" value="{!lstWrapper}"  var="item">
                <apex:column headerValue="Name">
                    <apex:outputLabel value="{!item.sName}" />
                </apex:column>
                 <apex:column headerValue="Gender">
                 <apex:outputLabel value="{!item.isFlag}" />
                </apex:column>
            </apex:pageBlockTable>            
    </apex:pageblock> 
    
     </apex:form>
</apex:page>

 

public with sharing class dynamicController {

    public PageReference AddRecord() {
        
       //Assign your own data to do this. for testing I just placed the dummy data.
       
       //Test Data
        MyWrapper oWrapp = new MyWrapper();
        oWrapp.sName='Test1'; 
        oWrapp.isFlag= false; 
        lstWrapper.add(oWrapp);
    
        return null;
    }


     public list<MyWrapper> lstWrapper {get;set;} 
      
     public dynamicController(){
        this.lstWrapper = new list<MyWrapper>();  
        MyWrapper oWrapp = new MyWrapper();
        oWrapp.sName='Test'; 
        oWrapp.isFlag= true; 
        lstWrapper.add(oWrapp);
              
     } 
      public class MyWrapper{
          public string sName{ get;set;}
          public boolean isFlag{get;set;}
      }
      
}

Your way is fine. I have done this in a bit different way, here is my code:

 

Apex Class:

public class Test
{
public List<Integer> counterId{get;set;}
List<SelectOption> options{get;set;}
public Test(ApexPages.StandardController controller)
{}
public Test()
{
options = new List<SelectOption>();
options.add(new SelectOption('Audi','Audi'));
counterId = new List<Integer>();
counterId.add(1);
}
public PageReference addFilter()
{
counterId.add(1);
return null;
}
public List<SelectOption> getCars()
{

return options;
}
}

 Visualforce Page:

 

<apex:page controller="Test" tabStyle="User" standardStylesheets="false">
<apex:form >
<apex:pageBlock id="thPB" >
<apex:commandButton value="Add New Row" action="{!addFilter}" reRender="thPB"/>
<apex:pageBlockSection >
<apex:repeat var="filter" value="{!counterId}">
<apex:inputText />
<apex:selectList >
<apex:selectOptions value="{!Cars}"></apex:selectOptions>
</apex:selectList>
</apex:repeat>
</apex:pageBlockSection>

</apex:pageBlock>

</apex:form>
</apex:page>

 I am able to add elements on click of add row.

What do you think about this?

Let me know your thoughs.

Thank you!

Hi Lakshman,

 

I tried your code and I am able to add rows dynamically.

 

Now the problem is, these rows I want to use for inserting custom object records. But, I am able to insert only last row record and not the previous one. Can you please tell me why this happening?

 

Thanks.

{
       counterId = new List<Integer>();
       
       counterId.add(1);       
}

{
    te = new Teaching_Experience__c();    
    te_List.add(te);
    counterId.add(1);
    return null;
}
public PageReference save()
{
    insert te_List;
    return null;
}

 

<apex:pageBlock id="thPB">

You could add a saving logic within the addRow method so that everything that has been modified is saved before the page refreshes.
