checked="{!IF(isWebAppActive == false,"checked","")}"

I am using this code to check/uncheck checkbox on VFpage but it is giving me this error.

Element type "input" must be followed by either attribute specifications, ">" or "/>".

How can I check/uncheck checkbox on VF page?

 

I want to create a list view like this image for mobile devices. I tried this using grid in the code. 

<div class="slds-grid slds-wrap pd-5">
                    <div class="slds-col slds-size_3-of-4">
                        <div class="slds-col">
                            Amazing enterprise
                        </div>
                        <div class="slds-col">
                            Amazing enterprise
                        </div>
                        <div class="slds-col">
                            Amazing enterprise
                        </div>
                    </div>
                    <div class="slds-col slds-size_1-of-4 slds-float_right slds-grid_align-center">
                        0.25
                    </div>
                </div>

But unable to achieve it. Is this possible using grid? Or should I use a table instead? I also want to avoid scrolling in smaller devices.

Created a visualforce page containing a canvas app then checked "Available for Lightning Experience, Lightning Communities, and the mobile app".

<apex:page >
 
    <apex:canvasApp namespacePrefix="" developerName="klientsumit" parameters="{showPage:'timesheet'}"/>
 
</apex:page>

But still it is not available in mobile navigation menu item list.

I cannot understand what I am missing. Please help.
 

I created a connected app with canvas app signed request enabled. This canvas app is used in multiple visualforce pages. I have a nodeapp which receives the signed request. Now I want to identify which visualforce page the signed request came. How would I do that? 

I created a canvas app that also runs on Salesforce android app. How can my canvas app detect if its running on Salesforce android/ios app or not?

I have a canvas app that has its own header and side navigation bar for mobile devices. When I open the canvas app from Salesforce mobile app then I am getting two headers and navigation bars as shown here.

I want to hide Salesforce navigation bar when I open my canvas app. Or is there any another solution. Please Help.

In LWC we write HTML template to add event handler like this.

<template>
    <input type="text" value={myValue} onchange={handleChange} />
</template>

but I want to write this code just like in vanilla HTML like

<template>
    <input type="text" value={myValue} onchange=handleChange() />
</template>

My final HTML generated should be the same.
 

I need to make multiple request apex method in order to fetch data in bulk on Visualforce page. So I made ajax request in for loop. Chrome enforces a maximum of six TCP connections per host. If I am requesting twelve items at once, the first six will begin and the last half will be queued. How can I resolve this problem. Does LWC fixes this issue?

I need to make a lot of Ajax request in my VFPage so I made Ajax request in a for loop. But in network tab in chrome it looks like only 4 Ajax requests can be made at a time and rest of the request are queued. How can I increase that or is there another way to achieve the same.

Is there any trailhead or tutorial to create or optimize Salesforce app that can work on large datasets and complex database operations? Currently when we do a lot of SOQL operations the response time gets worse. Please help

I have deployed the source of LWC component using sfdx force:source:push command and I need to open my LWC component in Developer Console defined like 

export default class GanttView extends LightningElement

How can I edit it using Developer Console?

I accidently pushed a github lwc repository using sfdx force:source:push command. I need to undo everything.I tried force:source:deploy:cancel but its too late now. Please help.

I need to approve bulk records so that I can set status of records as submitted. I used jsForce to approve records but it can only submit 1 record at a time.
Is there any other library or native APIs that can do the same?

I need to create monthly report of my data for my each and every user.  So there could be lots of records if there are lots of user. These records are normally created by a batch process running weekly as an example that runs for hours to calculate all the monthly utilization records for each user.
.
I do not want to compromise with performance of my application especially on peak hours. 

So should I continue with the batch process or do the same in real time using triggers? Or is there any other better way to achieve the same? 

Looks like there is problem with space. I am unable to resolve it. There are 590 error in this code. Please advise.

I want to create a list view like this image for mobile devices. I tried this using grid in the code.

But unable to achieve it. Is this possible using grid? Or should I use a table instead? I also want to avoid scrolling in smaller devices.

In LWC we write HTML template to add event handler like this.

<template>
    <input type="text" value={myValue} onchange={handleChange} />
</template>

but I want to write this code just like in vanilla HTML like

<template>
    <input type="text" value={myValue} onchange=handleChange() />
</template>

My final HTML generated should be the same.
 

why am I getting this error?

I want to display user profile picture in my nodejs connected app. It is working on chrome due to some sort of caching but its not working on safari for iphone/ipad and even when I use web container for android and ios.

I have a node application deployed on heroku that authenticates with salesforce using oauth2 webflow using connected app. I want to create a tab in salesforce that directly lands to the homepage of node app after authenticating with the logged in salesforce user. Initially I created a web tab but due to content security policy I was unable to load the page. Then I tried creating a canvas app but it also causes mixed content problem as we are redirected to http instead of https during oauth2 webflow. Is there any other way to achieve this?
