[SalesForce] lightning-record-edit-form look up filter

<lightning-record-edit-form object-api-name="Contact">
       <lightning-input-field field-name='AccountId' value="xxxxx"></lightning-input-field>
       <lightning-input-field field-name='LookUpFilter__c' ></lightning-input-field>

</lightning-record-edit-form>

The look up filter doesn't fetch any values even though "AccountId" is set, which is the basis for filtering look up records. Whats the best way to achieve this.

As you've observed, the built-in component needs a record to work with. However, there are open source versions (try searching for "lwc lookup field github") that you could modify to work without a record.

[SalesForce] Get values from Record-edit-form onload LWC

handleOnLoad() {
    let name = this.template.querySelector('.name').value;
    alert(name);
}

This will work.

BUT above approach is not good. You can get all the values based on recordId as below

handleOnLoad(event) {
    var record = event.detail.records;
    var fields = record[this.recordId].fields; // record['0010K000026Y******'].fields;
    const accName = fields.Name.value;      
    alert(accName);
    //const myfieldVal = fields.myfield__c.value;
    //alert(myfieldVal);
}

[SalesForce] Building an efficient LWC form without record-edit-form

Since lightning-input-field now has a required attribute, I decided to use lightning-record-edit-form. I'm using both lightning-input-field and lightning-input because some of the form fields reside in different objects. I use an onsubmit handler to do the validation that I needed.
