08 May 2023 / 2 minutes to read

We can set external HTML page content as template for our ListView control by making use of AJAX call.

let template: string;
let ajax: Ajax = new Ajax('./template.html', 'GET', false);
ajax.onSuccess = (e: string)=>{
    template = e;
}

ajax.send();

In the below sample, we have rendered smartphone settings template from external HTML file.
