Here are my Components: Child Component html :

        <div class="slds-m-around_medium " onload={handleLoad}>    
            <div class="slds-form-element">
                <lightning-input label="Search" value={searchKey}  minlength="1"
            <template if:true={records.data}>
                <template for:each={records.data} for:item="record">
                    <div class="zoom slds-pill-container" key={record.Id} data-contact-id={record.Id} >
            <template if:false={records.data}>  
                <p>No {selectedsobject} data available.</p>  
            <template if:true={error}>
                Error fetching {selectedsobject} records.. 


import { LightningElement,track,wire,api } from 'lwc';
import getsearchContactList from '@salesforce/apex/ContactController.getsearchContactList';

export default class ContactController extends LightningElement {

    @track records;
    @track error;
    @api recordId;
    @api selectedsobject;
    @api wherefield;
    @api searchKey = '';
    @track recordKey = '';

    @wire(getsearchContactList, {recordKey: '$recordKey' , searchKey: '$searchKey' , selectedsobject: '$selectedsobject' , wherefield:'$wherefield'}) 
    records ;

    handleLoad(event) {

        this.searchKey = event.target.value;

            selectedsobject : this.selectedsobject, 
            wherefield : this.wherefield

        this.recordKey = this.recordId;

and here is the Parent Component


<c-childcomponent selectedsobject="Contact" where-field="AccountId" ></c-childcomponent>

    Welcome to SFSE. Pls use {} for code formatting – salesforce-sas Sep 26 '19 at 14:01
  • Thank You Salesforce-sas for Editing my Question. and yes this is my first Question :) – Padam Sep 26 '19 at 14:03

Lightning page can provide recordId only to the top most custom LWC/AURA component. You need to pass down the record id down the hierarchy.

Make a Component Aware of Its Record Context: Define @api recordId in parent component in JS file.

Now, pass the record id to child:

<c-childcomponent record-id={recordId} selectedsobject="Contact" where-field="AccountId" ></c-childcomponent>

    Thank you so much Salesforce-SAS. This worked like a Charm. You are the Best :) – Padam Sep 26 '19 at 14:21
  • Using the above child LWC component, 1 last scenario I am working on is to embed LWC in Aura and pass the parameters in LWC. All other paramertes are working except recordId {<aura:component implements="flexipage:availableForAllPageTypes,force:hasRecordId" access="global"> <aura:attribute name="recordId" type="String" /> <c:childcomponent selectedsobject="Contact" recordId="{!v.recordId}" wherefield="AccountId" /> </aura:component>} – Padam Sep 26 '19 at 16:52
