Master Check Box To select all records in Table VisualForce Page.

Provide a master checkbox before all record rows means if user selects that all records will be selected.

- Create VisualForce Component for master check Box.

Component >>

<apex:component >

<script>
function cvCheckAllOrNone(allOrNoneCheckbox) {

    // Find parent table
    var container = allOrNoneCheckbox;
    while (container.tagName != "TABLE") {
        container = container.parentNode;
    }

    // Switch all checkboxes
    var inputs = container.getElementsByTagName("input");
    var checked = allOrNoneCheckbox.checked;
    for (var i = 0; i < inputs.length; i++) { 
        var input = inputs.item(i);
        if (input.type == "checkbox") {
            if (input != allOrNoneCheckbox) {
                input.checked = checked;
            }
        }
    }
}
</script>

<apex:inputCheckbox onclick="cvCheckAllOrNone(this)" title="Toggle All Rows"/>

</apex:component>

You can add a checkbox to the header row of your checkbox column that uses it to check all or none of the checkboxes:

In visualforce page add the component.

<apex:column >
    <apex:facet name="header">
        <c:CheckAllOrNone />
    </apex:facet>
    <apex:inputCheckbox value="YOUrCheckBoxValue"/>
</apex:column>


As this runs at the client side it is nice and quick.

Salesforce auto-create Folder for New Account.

Trigger for Creating Folder On Account Insert.

trigger BoxFolderCreationTrigger on Account (after insert) {
    
    public Set<ID> accids = new Set<ID>();

 for(Account acc : Trigger.New) {
  accIds.add(acc.Id);
 }
 
 if(accIds.size() > 0) {
  BoxFutureClass.createFolder(accIds);
 }
    
}

As Call-out is not allowed in Trigger.Here i have call Future class method for call-out.

Snippet OF Future Class.

global class BoxFutureClass
{
    @future(callout=true)
    public static void createFolder(set<ID> AccIds) {   
        Map<String,String> boxFRUPMap = new Map<String,String>();

        for(box__FRUP__c bF : [SELECT box__Folder_ID__c,box__Record_ID__c FROM box__FRUP__c where box__Object_Name__c = 'Account' limit 9999]) {
            boxFRUPMap.put(bF.box__Record_ID__c,bF.box__Folder_ID__c);
        }
        
        for(Account acc : [Select id,name from account where id IN :AccIds]) 
        {
         
            box.Toolkit boxToolkit ;
       
            if(!boxFRUPMap.containsKey(acc.Id))
            {
                boxToolkit = new box.Toolkit();
               
                String accountFolderId = boxToolkit.createFolderForRecordId(acc.Id,null, true);
             
                boxToolkit.commitChanges();
            }
               
                
          }
    }
 }
