New Hint Control - DevExpress ASP.NET (v17.1)

ASP.NET Team Blog
21 April 2017

We're introducing a new ASP.NET control in the v17.1 release: the Hint control.

The Hint control provides, well, hints. A small notification popup, in other words. In the image below, we're using the new Hint control to show the full GridView cell text on the mouse-over event:

This saves you from defining wide columns on the GridView but still be able to show the user the full text of the cell. Previously, we relied on our handy DevExpress ASP.NET Popup control for similar tasks. However, the popup control provides a lot more features and tends to be heavier for small tasks that require only a hint. So, we created the Hint control to offer you another way to display lightweight notifications.

Light Client-Side

The unique thing about our new Hint control is that it's mostly a client-side control which is wrapped in a server-side ASP.NET control. Why would we do that? Well, the Hint control is really lightweight and it would be overkill to generate it on the server.


As you might expect, the DevExpress ASP.NET Hint Control generates its content on demand and displays it within a box along with an arrow targeting the specified UI element on a web page.

Features include:

  • A trigger action to display the hint (hover, click, focus, programmatic).
  • Customizable delay before the display of the hint.
  • Animation effects.
  • Callout element availability.
  • Position over the target element (bottom, top, left, right).
  • Title text/markup (static or retrieved from the target element's attribute).
  • Content text/markup (static or retrieved from the target element's attribute).
  • Customizable size (height/width).
  • Absolute positioning (x/y).
