I want to be able to delete multiple rows out of the table. So delete all checked rows with he delete button. How do I do this? 

public with sharing class controller {

public List<sObjects> myList 	{get; set;}
public String pId		{get; set;}							
	
    //CONSTRUCTOR
    public controller(){
    	 pId = ApexPages.CurrentPage().getparameters().get('id');
    	 myList = loadlist(); 
    }
    
    public list<People_Skill__c> loadList(){
    	List<sObjects> myList= [SELECT Id, name__c, type__c, comment__c,    FROM object__c WHERE id=:pId];
    	return mylist;
    }
}

Hi,

You need to use wrapper class to acheive uor purpose.

 

Controller:

public class DeleteElementTesting {
       List<wrapperClass> accList;
       public List<wrapperClass> getAccounts() {
               if( accList == null ) {
                    accList = new List<wrapperClass>();
                    for( Account acc : [select id,Name,type from Account]) {
                           accList.add( new wrapperClass( acc,false));
                   }
            }
            return accList;
       }

 

       public void doDelete() {
                List<Account> selectedAcc = new List<Account>();
                for( wrapperClass cs: getAccounts()) {
                      if(cs.isSelect) {
                           selectedAcc.add( cs.accObj ); 
                      }
                }
               delete selectedAcc;
                accList = null;
        }

       public class wrapperClass {
              public Account accObj{get;set;}
              public Boolean isSelect{get;set;}
              public wrapperClass( Account accObj, boolean isSelect ) {
                     this.accObj = accObj;
                     this.isSelect = isSelect;
              }
        }
}

<apex:page controller="DeleteElementTesting">
       <apex:form>
             <apex:pageblock>
                       <apex:pageBlockButtons location="top">
                                 <apex:commandButton id="DeleteBtn" value="Delete" action="{!doDelete}" />
                        </apex:pageBlockButtons>
                        <apex:pageBlockTable value="{!Accounts}" var="acc">
                                  <apex:column >
                                          <apex:inputCheckbox value="{!acc.isSelect}"/>
                                  </apex:column>
                                  <apex:column>
                                        <apex:facet name="header"> <apex:outputText value="Name" /> </apex:facet>
                                        <apex:outputField value="{!acc.accObj.Name}" />
                                   </apex:column>
                                  <apex:column >
                                             <apex:facet name="header"> <apex:outputText value="Type" /> </apex:facet>
                                             <apex:outputField value="{!acc.accObj.Type}" />
                                  </apex:column>
                            </apex:pageblockTable>
                      </apex:pageblock>

This work when the object is an account but when I am using a custom object, what goes into the value of the table? Because the list is a wrapper class list and so what should the table display? 

 

  <apex:pageBlockTable value="{!Accounts}" var="acc">

 
Sneha PatilSneha Patil

The value of the PageBlockTable should contain the wrapper list

 

In the above example it should be

 

  <apex:pageBlockTable value="{!accList}" var="acc">

 

Hope this answer hepls!!
