Tooltip in ASP.NET MVC Kanban control

The tooltip is used to show the card information when the cursor hover over the card elements using the EnableTooltip property. Tooltip content is dynamically set based on hovering over the card elements.

If you wish to show tooltip on Kanban board custom elements, you need to add e-tooltip-text class name of a particular element.

Tooltip template

You can customize the tooltip content with any HTML or CSS element and styling using the TooltipTemplate property. In the following demo, the tooltip is customized with HTML elements.
