Editor's Note: Late Edition

I'm sure it's still November somewhere west of Dundas Data Visualization… We've been very busy!


Microsoft Silverlight

Dundas is proud to announce the upcoming release of Silverlight capabilities for Dundas Chart for ASP.NET. This exciting new add-on lets you integrate Dundas Chart into Silverlight applications. A specialized front end is provided, making Silverlight integration quick and powerful — and all of your favorite ASP.NET interactive features are retained and even enhanced:

  • Full Hit Testing
  • Real-Time Charting
  • Image Tooltips
  • Text Tooltips
  • Drill Down
  • And more!

Setting up the Silverlight add-on is extremely easy and it lets you write rich and interactive features on the web for your charts. The official release of this outstanding functionality will be with Dundas Chart version 7.0 (under development) but you can get an alpha version shortly if you would like to do some early testing. If you would like to receive a pre-release copy of the Silverlight add-on or if you simply have some questions, please email

A live interactive demo can be found at on our server.

Dashboarding and Business Intelligence

Dashboard Insight

Dundas continues to be a proud sponsor of Dashboard Insight, the premier online magazine for all things dashboard. At the DI website, you can find an incredibly large collection of dashboard articles written by some of the best minds in the industry, as well as daily news updates, white papers and interviews with today's business leaders. In addition, DI has recently launched an online catalog hosting information on the absolute best companies in the space.

Dundas Customer Dashboard Gallery

Send us screen shots of your dashboards that use Dundas components!

We're currently working on a new web page containing dashboards created by our clients with Dundas products. While the goal is to show off the great work someone outside of Dundas can do, it is understood that many customers have "non-public" dashboards. But if you have a dashboard image that can be shown publicly and it fits in with our messaging and theme, we'd love to include it!

Posting on the Dundas website is beneficial for both of our companies. Since your company will also be linked to the site, visitors who might not be familiar with you will have access to your website. This will not only increase the amount of traffic to your site, it will also provide you with some exposure for free. Additionally, Google uses the amount of people coming to your website from another source as part of their calculation for determining page ranking. So having a link on Dundas will also help you in that regard as well.

If any of this interests you, please send us a note!

Adding an HTTP Handler to Gauge

Using Gauge with an HTTP Helper

When the Dundas Gauge control renders in a page, it writes an image of the gauge to a folder on the web server so that the browser can later retrieve it when it loads the <img> tag. This means that the web application must be given write access to the temporary folder or the gauge will not work. Since web applications usually only have read access to any subfolders, using the web gauge control requires some extra configuration.

Read on to find out how to use an HTTP Handler with gauge to remove this temporary file requirement.
