Get lightning:recordeditform Field Values in onsuccess Event

Biswajeet April 30, 2018 No Comments

Sometimes we can have a requirement to get field values, record Id, record type Id, child relationships information in onsuccess event of lightning:recordeditform. In below example, I’m creating “Lead” object record using lightning:recordeditform and after successfully saving the record, getting the field values in onsuccess event.

Lightning Component:

<!--Sample.cmp--> 
<aura:component implements="flexipage:availableForAllPageTypes,force:appHostable">
    
    <!--Component--> 
    <div class="slds-m-around--xx-large">
        <lightning:card title="Lead" iconName="standard:lead" class="slds-p-around_medium">
            <lightning:recordEditForm aura:id="leadCreateForm" objectApiName="Lead" onsuccess="{!c.handleOnSuccess}">
                <lightning:messages />
                
                <div class="slds-grid">
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="FirstName"></lightning:inputField>
                    </div>
                    <div class="slds-col slds-size_1-of-2 slds-p-around_medium">
                        <lightning:inputField fieldName="LastName"></lightning:inputField>
                    </div>
                </div>

Salesforce Lightning ListView

Biswajeet April 16, 2018 1 Comment

A lightning:listView component represents a list view of records that you own or have read or write access to, and records shared with you. They also include records owned by or shared with users in roles below you in the role hierarchy. You can see only the fields that are visible according to your page layout and field-level security settings.

To create a list view, specify which object to render with the objectApiName attribute and which list view to use with the listName attribute. The list view doesn’t require additional Apex controllers or Lightning Data Service to display record data. Here is an example which displays a “My_Accounts” list view of Account object.

Note: This component requires API 42.0 and later.

Salesforce Lightning TreeGrid

Biswajeet April 16, 2018 8 Comments

A lightning:treeGrid component displays hierarchical data in a table. Its appearance resembles lightning:datatable, with the exception that each row can be expanded to reveal a nested group of items. Rows that contain nested data display a chevron icon to denote that they can be expanded or collapsed. Each column can be displayed based on the data type. Here is an example of lightning:datatable.

Note: This component requires API version 42.0 and later.

Apex Controller:

public class SampleAuraController {
    
    @AuraEnabled
    public static List <Account> getAccountList() {
        List<Account> accList = new List<Account>();
        accList = [SELECT Id, Name, NumberOfEmployees, Phone,
                   (SELECT FirstName, LastName, Email FROM Contacts)
                   FROM Account LIMIT 10];
        return accList;
    }
}

Lightning Component:

<!--Sample.cmp--> 
<aura:component controller="SampleAuraController" implements="flexipage:availableForAllPageTypes" access="global">
    <aura:attribute type="Account[]" name="acctList"/>
    <aura:attribute name="gridColumns" type="List" />
    <aura:attribute name="gridData" type="Object" />
    <aura:attribute name="gridExpandedRows" type="Object" />
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    <div class="slds-m-around_xx-large">
        <lightning:treeGrid aura:id="accTree" columns="{!v.gridColumns}" data="{!v.gridData}" keyField="Id"/>
    </div>
</aura:component>

Lightning Component JS Controller:

({
    doInit : function(component, event, helper) {
        var columns = [
            {
                type: 'text',
                fieldName: 'Name',
                label: 'Account Name'
            },
            {
                type: 'number',
                fieldName: 'NumberOfEmployees',
                label: 'Employees'
            },
            {
                type: 'phone',
                fieldName: 'Phone',
                label: 'Phone Number'
            },
            {
                type: 'text',
                fieldName: 'FirstName',
                label: 'First Name'
            },
            {
                type: 'text',
                fieldName: 'LastName',
                label: 'Last Name'
            },
            {
                type: 'email',
                fieldName: 'Email',
                label: 'Email'
            }
        ];
        component.set('v.gridColumns', columns);
        var action = component.get("c.getAccountList");
        action.setCallback(this, function(response){
            var state = response.getState();
            if (state === "SUCCESS" ) {
                var resultData = response.getReturnValue();
                for (var i=0; i<resultData.length; i++ ) {
                    resultData[i]._children = resultData[i]['Contacts'];
                    delete resultData[i].Contacts; 
                }
                component.set('v.gridData', resultData);
            }
        });
        $A.enqueueAction(action);
    }
})
