Editor's Note: Convention Season

We're extremely busy at Dundas these days, getting ready for convention season, developing a very interesting new product, doing custom development for our consulting customers, and fielding technical support requests.

Poll

Platform poll

To help us plan our future developments, we'd like each of you to enter our platform poll, to tell us about your current development platform.

This data will be kept private (although next month we'll publish the results for you to see) and won't be used to pester you in any way (in fact, it's completely anonymous).

Thanks!

Add-ons

Add-ons

Earlier this month, we discovered that the installers for several of the Product Add-ons had been reverted to earlier versions without Reporting Services or SharePoint support.

We apologize for any disturbance this may have caused.

If the add-ons you've downloaded are missing their Reporting Services and SharePoint DLLs, you can simply download them again from the Product Add-ons page. This will ensure that you have the latest version of the source code and documentation as well.

Chart

Featured Sample

Featured Property

This month's feature Chart property is the SmartLabels property found on Series objects.

SmartLabels™ let you apply data point labels even on crowded charts. The SmartLabels will automatically reposition themselves for maximum readability and draw callout lines when necessary to link the label with the data point.

To enable SmartLabels on a series, set its SmartLabels.Enabled property to true. Most of the time, that's all you need to do to improve your chart's readability.

SmartLabels are highly configurable, with a number of properties for tweaking their behavior and callout line appearance.

Featured Sample

Featured Property

In Windows Forms, the RefreshRate property lets you control the number of times per second that the gauge control is redrawn. This is a trade-off between the overall performance of the gauge and the smoothness of any pointer motion.

A low RefreshRate (the default is 30 redraws per second) will improve performance, while a higher RefreshRate will prevent your pointers from becoming choppy or erratic.

Increasing the RefreshRate is generally a bad idea (it impacts gauge performance more than any other factor), but reducing it can really help improve performance when you don't need smooth animation.

Map

Featured Sample

Sample - Choosing a Map Projection

The Choosing a Map Projection sample demonstrates the different map projections supported by Dundas Map. You can find it in the Dundas Map Samples Environment (under Getting Started → Choosing a Map Projection).

Featured Property

In Windows Forms, the map control's NamedImages property lets you store images along with the other map data. These images are serialized along with the map, and can be referenced by name in any map property that expects an image path.

This lets you develop map applications using custom images without filling your application with hard-coded images paths. The NamedImages collection operates like a central image repository for your map.
