I Build lightning web component to import csv file.
My lighnting web component reads data as text and sends the string to apex class.
Apex class parses the text and add records to a list. Can I insert 10000 records with apex. Does it hit any limits such as CPU time limit, Heap size limits etc? Is there any other suggestion to do this task?

Hi all,
I want a drop down menu by using lightning-button-menu in  data table using Lightning Web component.
I have created the Data table and I want a drop down menu with the different values. 
Data table is as follows:

HTML:
<template>
    <lightning-card title='Data table'>
       
    <div style="height: 300px;">
        <lightning-datatable
                key-field="id"
                data={data}
                columns={columns}
                >
        </lightning-datatable>
        <div>{error}</div>
    </div>
</lightning-card>    
</template>
JS:
import { LightningElement,track,api,wire } from 'lwc';
import getAccountList from '@salesforce/apex/AccountHelper.getAccountList';
const columns = [
    { label: 'Account name',
    fieldName: 'Name',
    type: 'text',
    sortable: true
    },
    {
        label: 'Type',
        fieldName: 'Type',
        type: 'text',
        sortable: true
    },
        
];
export default class Test extends LightningElement {
    data = [];
    columns = columns;
    wiredActivities ;
    records = '';
    error;
    @wire(getAccountList,{
        }
    )
    wiredCases(value){
        this.wiredActivities = value;
        const { data, error } = value;
    
    if(data){
        let dataEditing = JSON.parse(JSON.stringify(data));
        this.records = dataEditing.length;
        this.data = dataEditing;
        
    }else if(error){
        this.error = error;
    }
    
}
}
Apex class: 
public with sharing class AccountHelper {
    @AuraEnabled(cacheable=true)
    public static List<Account> getAccountList() {
        return [SELECT Id, Name, Type, Rating,
                Phone, Website, AnnualRevenue
            FROM Account LIMIT 10];
    }
}

I want a drop down menu in every row and that should be clickable.
Thank you in advance!

I have taken reference from :
https://developer.salesforce.com/docs/component-library/bundle/lightning:icon/documentation
https://salesforce.stackexchange.com/questions/227124/custom-icons-from-static-resource-on-lightningicon-not-working
 

I am trying to change the font color of a custom field values displayed in a table. This is based on a condition wherein if this custom field's value is less than a specific amount, it will display said value in red font.

I have no problem in displaying the correct values, but each time I try to attempt to style the values, nothing changes.

Note: computedValue is the variable assigned in Apex class to get the value of the custom field named Computed_Value__c

Below are some portions of the codes I have problem with:

<!-- body section in html-->
<tbody>
<template if:true={actualResults}>
    <template for:each={actualResults} for:item="keyValue">
        <tr key={keyValue.key}>
            <td scope="col" class={keyValue.styleColor}>
                <div>{keyValue.value.computedValue}</div>
            </td>
        </tr>   
    </template> 
</template>
</tbody>

javascript file:

import getAllResult from '@salesforce/apex/SampleController.getAllResult';

export default class SampleLWC extends LightningElement {

@track actualResults = [];

//section in javascript

getAllResult()
    .then(result => {
        if (result) {
            let mapResult = [];
            var isLess;
            var styleColor;    

            for (var key in result) {
                tempMapData.push({ key: key, value: result[key] });
                        
                isLess = result[key].Computed_Value__c < 1000;
                styleColor = isLess ? 'background-color:red' : 'background-color:none';
                
            }
            this.actualResults = mapResult;
        }
    })
    .catch(error => {
        this.error = error;
    });
}

 

@track data; what data denote in wire method in LWC can any one explain
thank you
 

I am trying to use CSS to rotate the text and works well normally. but when try to render AS pdf, the CSS for rotate will break.

Can anyone suggested, that how to resolve the issue.

.textRotate {
                /* Safari */
                -webkit-transform: rotate(-90deg);
                
                /* Firefox */
                -moz-transform: rotate(-90deg);
                
                /* IE */
                -ms-transform: rotate(-90deg);
                
                /* Opera */
                -o-transform: rotate(-90deg);
                
                float: left;
                    position:absolute;
                background:green;
            }

Will it work - to connect Field devices with their IoT and LWC to monitor data change without refreshing the page. 
What is the right way to implement it? 

I was looking for a sample project. 
Can somebody share one? 

I saw IoT Salesforce  - is it possible to use it as Streaming data for LWC?

Hi,
Can anyone of you help me with the code for multiselect combobox? I don't want duallistbox, I want a combobox or picklist where user can select more than 1 value.

Thanks,
Vai
