Editor's Note: Welcome to 2008

Starting this month, we're going to introduce some more changes to the Dundas Technical Newsletter. We're reconsidering our monthly publishing schedule (to give us more time to produce more articles with more depth) and we'll be refocusing the various sections to concentrate on things that are interesting for Dundas developers (and that separate Dundas products from the others).

Development Platform Poll

To help with our product planning and see what you're doing out in the real development world, we're conducting a poll asking about your primary development platform.

Take the poll!

Add-ons go "Pro"

This month we're introducing our new Dundas Product Add-Ons section. Dundas Product Add-Ons provide code for new features and functionality.

Even better, the Dundas Product Add-Ons feature professional-quality production code in C# and VisualBasic.NET, full documentation, and interactive web-based demos. Because the source is there, you can see exactly how we implement these features using standard Dundas APIs and extend them to do exactly what you need.

In the coming months, we will be further expanding the add-ons, providing new features to our entire line of data visualization products – and it's all free for those with valid Dundas product licenses!

Using Parameters in the Data Connection Wizard

Parameters in the Data Connection Wizard

In Dundas web parts for SharePoint, parameters (or "filters") are provided in the data connection wizard for changing the data displayed based on values passed in from other web parts. This is accomplished using web part connections, which many SharePoint web parts support.

Displaying multiple currency symbols

¢ • $ • € • ƒ • £ • ₤ • ¥

In financial charts, it's often necessary to display multiple currency symbols. Using .NET's "C" format string and the CurrentCulture object isn't a solution, because it only lets you access the current culture's currency symbol. Using a custom culture for specific controls without affecting other controls is too complex. Luckily, Dundas controls are culture independant. They take advantage of .NET's Unicode support so we can easily access a huge variety of characters and symbols.

Featured Property

The ValueSource property lets you specify the name of an input value or calculated value to be used as a source for an indicator (NumericIndicator or StateIndicator), Knob, or pointer's (CircularPointer or LinearPointer) value. When the ValueSource is set, a History is created to track the values, which is then used to generate calculated values and to enable playback.

Map

Get more out of Dundas Map in your applications.

Featured Sample

The South East Asia sample (found in the Dundas Samples Environment under Map Applications → South East Asia) demonstrates using legend hit testing to highlight map areas.

Featured Property

The ShapeData property of the Shape class (accessible via your map's Shapes property) gives you access to the graphical primitives that make up a shape. This lets you manipulate each of your map's Shapes directly, to modify the Points and Segments that make up the shape. Accessing the ShapeData can be useful for merging data sets and creating your own shapes.

Note: If your changes to a shape's Points and Segments change its size, be sure to update the MaximumExtent and MinimumExtent to reflect the shape's new size.
