How can I display a message in the Telerik UI for ASP.NET Core Chart when its data source is empty?


The following example demonstrates how to achieve such behavior. Note that the div element of the message is positioned and decorated through CSS.

        .Title("Site Visitors Stats")

        function onRender(e) {
            var view = e.sender.dataSource.view();
            var parent = e.sender.element.closest('.container')
            createOverlay(view.length, parent)
        function createOverlay(viewLength, parent) {
            if (viewLength === 0) {
                parent.append("<div class='overlay'><div>No Data</div></div>")

        .container {
        position: relative;

        .overlay {
        width: 100%;
        height: 100%;
        position: absolute;
        top: 0;
        left: 0;
        opacity: .5;
        background-color: #6495ed;
        text-align: center;

        .overlay div {
        position: relative;
        font-size: 34px;
        margin-top: -17px;
        top: 50%;

For the complete implementation of the suggested approach, refer to the Telerik REPL example on displaying the Chart when its data source is empty.
