Display 🚩 Flags conditionally using formula in Salesforce Lightning

In this article I will share an example to display Flag images based on a formula value. In my case the requirement was to display flags on lead based on user's login time. Let say if user is checking the lead in between 08:00 AM EST to 05:00 PM EST so the formula should show Green flag and user can call the client.But if user is logged in after his working hours then it should show 🚩 Red flag to indicate user that he/she can not call the client at the moment.To accomplish the functionality I created a formula field with return type TEXT on Lead object and applied below formula to do the trick.
Formula1 2 3 4IF((HOUR(TIMENOW())-4)>7&& (HOUR(TIMENOW())-4)<17, IMAGE("/img/samples/flag_green.gif", "Green Flag"), IMAGE("/img/samples/flag_red.gif", "Red Flag") )
In the above formula I am using TIMENOW() to get the current time and HOUR() to get the hour only from the TIMENOW() function. The result will be in GMT so to conver…

Client Side Search in Lightning Data Table in Lightning Component Salesforce

In this article I will implement the Client Side Search functionality in Lightning Data Table in a Custom Lightning Component.Client Side Search allows user to search the data from the page itself. You don't have to query records each time, because using client side search we can use the on page database. #Salesforce #LightningComponent #DataTable
Check the code below
Component 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22<aura:componentcontroller="LightningDTCTRL"implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction"access="global"><aura:attributename="recordList"type="List"/><aura:attributename="allData"type="List"/><aura:attributename="columns"type="List"/><aura:attributename="sortedBy"type="String"d…

Understand Queueable Apex with Example and Test Class | #Salesforce

Queueable Apex is similar to @future methods. It is an asynchronous apex method. It allows you to submit jobs for asynchronous processing with some additional benefits comparing to @future methods.Benefits : Queueable apex supports non-primitives like SObject and custom Apex types.We can monitor the status and progress of Queueable method using the returned Id of AsyncApexJob.We can chain one job to another by starting the second job from a running job.Limitations :  It shares limits of async Apex & Governor Limits.In a single transaction you can add maximum 50 jobs in the queue.While chaining jobs, only one child job can exist for each parent job.
Below example is taken from the Queueable Apex trailhead, the purpose of this is just to share a example of Queueable Apex with test class.
Requirements Create an Queueable Apex class that inserts Contacts for Accounts. Create a Queueable Apex class that inserts the same Contact for each Account for a specific state. Write unit tests that ac…
