I am not 100% sure how to change this to be recognized in Lightning.  The Opportunity Name / ID is not being added to the Quote in Lightning.  Works just fine in Classic.  Any guidance would be great.

        if(theOpp.Account.RecordType.Name =='Prospect') {
            PageReference pref =  new PageReference('/0Q0/e?Name=' + EncodingUtil.urlEncode(theOpp.Name,'UTF-8')  + '&retURL=%2F' + theOpp.Id + '&oppid=' + theOpp.Id);
            return pref;
        }
        else {
            PageReference pref =  new PageReference('/0Q0/e?Name=' + EncodingUtil.urlEncode(theOpp.Name,'UTF-8') + '&BillingName=' + EncodingUtil.urlEncode(theOpp.Account.Name,'UTF-8') + '&retURL=%2F' + theOpp.Id + '&oppid=' + theOpp.Id);

I would like to know what are the Events available in LWC and Aura components? 
and how it can be utilized effectively(with example)? 

I would like to trigger an LWC page from Apex method. I tried using PageReference as a return type but it didn't help me. If someone tries the same please add your comments. 


Here is the reason why I am trying this:
 I am trying to make an API call from Apex but it through a certification Error but If I try the same Endpoint from LWC I am getting the expected response. In this case, I am planning to write a schedule (every 30min) class and invoke the LWC component. please add your comments or what could be the alternate solution. 

when I make API call from apex I am receiving Certification Error but when trying the same endpoint from LWC It works fine what could be the reason for this.

@track pickListValueList=[];

for(let key in data) {
if (data.hasOwnProperty(key)) {
this.pickListValueList.push({label: data[key], value: key, classVal:"slds-m-left_x-small slds-m-bottom_x-small slds-button removeColor"});
}
}

data I am getting it from the back end as a Map<String, String>. find the value of pickListValueList and update the classVal of that element.

Hi All,

I have a Wired Method like this:
 

recordId = '';
searchString;

@wire(searchUsers, {recordId: '$recordId', searchString: '$searchString'})

The method is working correctly, but the method is running everytime the recordId or the searchstring is changed. I would only like to run it when the searchstring is being changed & also not onload of the component. How can i manage this?

 

My requirement is when i click the refresh button it should display the date and time like standard report chart.there is any solution

      <button class="slds-input__icon slds-button slds-button_icon iconheight" onclick={today}>

Hi 

I want to set a variable from an apex class at the beginning of the component load.
I guess connctedCallBack should work for me. but as I am using a promise call there it's not working there, though if I write static code there, it works for me. What can I do to achieve this motive?

Code sample that I am using:
 

connectedCallback() {
        console.log('connectedCallback Called! ');
        //console.log(this.bookMarked);
        console.log('Item Id: ' + this.itemId);
        console.log('Checking if already bookmarked'); IsBookmarked({ sItemId: this.itemId })
            .then(result => {
                console.log(result);
                console.log(this.buttonText);
                if (result) {
                    this.buttonText = "Remove from bookmark";
                    this.updateButtonText('Remove from bookmark!');
                }
                else {
                    this.buttonText = "Bookmark Me!"
                    this.updateButtonText('Bookmark Me!');
                }
                console.log(this.buttonText);
            })
            .error(error => {
                console.log('IsBookmarked Failed:' + error.body.message);
            });

    }

 

Hi All,

I am new to creating custom lightning components and I am trying to create a button/link in a Community so that when the button/link is clicked a string of text is shown below the button.  How can I accomplish this?  Thank you in advance!

So I just made my new TP, found the settings to rename it. clicked on the Launch your hands-on org after making sure it was the default hands on org and I get an error:
This site can’t be reached
cunning-raccoon-380385-dev-ed.lightning.force.com’s server DNS address could not be found.

I have my normal DE org connected as well and it takes me to the login page for that org where I can log in successfully. Not sure what I'm missing?
Any help is appreciated, Thanks!
