About RadTagCloud for ASP.NET AJAX

Telerik RadTagCloud for ASP.NET AJAX is a flexible UI component that displays a collection of user-generated tags accompanying the articles, posts, or videos on your website. Each tag has weight which corresponds to its popularity, importance or recurrence on the page. The keywords in the cloud have their own URL which navigates to a collection of items associated with the relevant tag. The user can easily customize the appearance of the control, choose the items that will be displayed in the cloud, their font size and color, sort the tags alphabetically or by weight, in ascending or descending order.

RadTagCloud and 70+ other controls are part of RadControls for ASP.NET AJAX, a comprehensive toolset taking care of the common functionality of your application, while leaving you with more time to work on the business logic of the app.

Get Started

  • Use Telerik’s Visual Studio Extensions (which you have installed together with the RadControls) to quickly create, upgrade and configure your RadControls projects. Save time by using the ready-to-use Visual Studio templates that cover common application scenarios.
  • Find the controls in need in your VS toolbox and use the Design-time surface and rich wizards to configure them quickly.
  • If you’d like to learn more about how to best implement the RadControls, browse the Telerik folder in your Start menu and use the shortcuts there to access the local demos, online documentation or open the sample examples app in Visual Studio.

Key Features

  • Distribution - specifies how the font size will be distributed among the items
  • Sorting - specifies in what order the TagCloud items will be listed. By default they are not sorted
  • Filtering Of The Items - Three properties control the filtering of the items: MinimalWeightAllowed, MaxNumberOfItems and TakeTopWeightedItems
  • MinimalWeightAllowed - specifies the lower bound for the item Weight
  • MaxNumberOfItems - specifies the maximal number of items that can (will) be shown in the cloud
  • MinFontSize and MaxFontSize - specify the range of the font size, the TagCloud items could have
