Editor's Note: Fall means support!

Now that summer is officially over, everyone seems to be jumping into new projects or rushing to finish existing projects. Focusing on work makes it easier to ignore the leaves piling up on the lawn and the lower temperatures (if you're in the northern hemisphere, at least).

The Dundas R&D group is no different, of course, but our Support folks are also kept extremely busy. All of these new (and old) projects lead to developers needing answers, and Dundas Support keeps a very low turn-around time locked to a very high standard of assistance for our customers.

There are, of course, several ways for you to get help for Dundas products. All of our documentation is online on our support site as well as hundreds of useful articles. Use the keyword search to find what you're looking for, and if you can't find it let us know what we've missed!

The Documentation Roadmap and Technical Newsletter Archive will also help you find interesting and useful information.

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!

Dundas Map and the ASP.NET Update Panel

Dundas Map for ASP.NET

When a map control is placed inside an update panel and an async postback occurs, the resulting map will be blank and loses all client-side functionality. This is due to the fact that the map generates initialization JavaScript for itself inside <script> tags and the code inside these tags is not executed by the browser during an async postback.

Read on to find out how to make Dundas Map work with the ASP.NET Update Panel.

Featured Property

This month's featured Chart property is actually something that you can use on any of the rendered-to-the-screen text properties, the keywords.

Chart supports a number of keywords (written as #KEYWORD). These act as placeholders for actual values and are replaced when the text is about to be rendered to the screen (or web page). For example, the #VALX keyword is replaced by the X value of the current DataPoint.

Unless a keyword is limited specifically to data points, series or legends, it can be used in any text property that ends up being displayed to the user.

Featured Property

The ImageUrl property found on gauge container objects lets you control where (and how) temporary images created by the ASP.NET gauge are created.

Using ImageUrl, you can store all of your gauge images in a single file (not a good idea; it could be overwritten before the client has finished downloading), an unlimited number of unique files, or using a round-robing sequence that you control.
