Editor's Note: Summer Slowdown

Did anyone actually experience the high-tech "summer slowdown" effect this year? It seems like we've been busier than ever, even with people randomly vanishing for vacations here and there. As a result, this month's newsletter is a bit lighter than July's, but next month we'll be back to normal.

Dundas Support I'd like to extend my thanks to the support staff here at Dundas for their help with this issue. It wouldn't have come together in time this month without them, since I was busy with a couple of other things (and a bit of a vacation). Thanks everyone!

Add-ons

Each month we publish two (or more!) add-ons, classes and code that you can mix in with your own code to get more out of your Dundas products! These add-ons include full source code for the add-on class and sample code demonstrating what it does and how to use it.

Series Dimmer

Series Dimmer By using this simple add-on to Dundas Chart, you can dim a given chart series. This will let you highlight an important or selected series without hiding any of the data.

This add-on shows you how easy it is to create a reusable add-on for Chart, and a very simple special effect that you can apply to the chart during rendering.

Questions & Answers

You've got questions about Chart, we've got answers!

Q. How can I serialize a Chart as an XML file?

Featured Property

AccessKey is inherited from the System.Web.UI.WebControls.WebControl class in the .NET Framework, the base class for all web controls. AccessKey is used to set or get a keyboard shortcut used to bring input focus to the control. For example, if a map's AccessKey property has been set to the letter m, the user will be able to press their M key when the page loads to navigate directly to the map.

The default is the empty string, which indicates that the property is not set (although the user can still use Tab to navigate to the control).

Highly detailed maps might cause performance problems in your application during rendering, whether you're targetting Windows Forms, ASP.NET, or Reporting Services. To reduce your application's in-memory footprint and CPU load, you can often simplify maps without adversely affecting the map rendering quality.
