The Telerik UI Tooltip TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI Tooltip widget.

The Tooltip displays a popup hint for a specific HTML element. Its content can be defined either as static text or loaded dynamically with AJAX.

Initializing the Tooltip

The following example demonstrates how to define the Tooltip.

   <span id="tooltip" class="k-button wider">Hover me!</span>

    <kendo-tooltip name="agglomerations" filter="span"></kendo-tooltip>

Basic Configuration

The following example demonstrates the basic configuration of the Tooltip HtmlHelper.

    <span id="tooltip" class="k-button wider">
        <a href="#">Hover me</a>

            .Events(events => events.Hide("onHide").Show("onShow"))


        function onHide() {
            // Hide Event function handler

        function onShow() {
            // Show Event function handler
    <kendo-tooltip name="agglomerations" filter="span" position="top" width="120">
            <open effects="fade:in" duration="300" />

Functionality and Features


For a complete example on basic Tooltip events, refer to the demo on using the events of the Tooltip.

Referencing Existing Instances

To reference an existing Tooltip instance, use the configuration option. Once a reference is established, use the Tooltip client-side API to control its behavior.

    // Place the following after your Telerik UI Tooltip for ASP.NET Core declaration.
        $(document).ready(function() {
            // The For() configuration option of the Tooltip is used to get its client-side instance.
            var tooltip = $("#tooltip").data("kendoTooltip");
