Show Slider from Hidden State

30 Jan 20252 minutes to read

This section demonstrates how-to render the Slider control in hidden state and make it visible in button click. We can initialize Slider in hidden state by setting display as none to it.

In the sample, by clicking on the button, we can make the Slider visible from hidden state, and we must also call the refresh method of the Slider to render it properly based on its original dimensions.

<!--button to show slider-->

<div id="container">

        args.text = new Date(totalMilliSeconds).toLocaleTimeString("en-us", custom);

    function renderingTicksHandler(args) {
        var totalMilliSeconds = Number(args.value);
        var custom = { hour: '2-digit', minute: '2-digit' };
        args.text = new Date(totalMilliSeconds).toLocaleTimeString("en-us", custom);
    }
    document.getElementById('button').onclick = function () {
	//slider visible from hidden state
        slider = document.getElementById("container");
