Based on a discussion forum request, today's web project shows you how to add sub menus to ContextMenu. This is a built-in function in all of the most recent daily builds of Map Suite, which you can download from the ThinkGeo Customer Portal. This project also demonstrates how to enable the ContextMenu's auto wrap feature when you click on the edges of the map.
In today’s Web project, we learn how to extend ScaleBarAdornmentLayer to create a custom scale bar that is based on a projection of choice instead of the projection of the map. This can be useful when the displayed projection of the map has highly distortable distances especially at high latitudes such as Spherical Mercator (used by Google Map, Virtual Earth, Yahoo maps etc). Using a scale bar based on distance geometry of the Geodetic (WGS84) projection will give a more accurate result. Note that the CustomScaleBar class is based on MapSuiteCore and can be used in any other versions of MapSuite such as Desktop.
This sample shows how you can suppress and draw exceptions in desktop overlays instead of throwing them. There is a little-known feature in the Map Suite Desktop Edition Overlay class that allows you to draw an exception in the event an exception is thrown during the drawing process. We have a default image we draw in this case; however, you can override this using the DrawExceptionCore method and draw whatever you want. By default we always throw expections, but to start drawing them you can use the Overlay.DrawExceptionMode property.
In this web-based project, we show you how to do a two-way interaction between the features in an InMemoryFeatureLayer and their information in GridView. If you click on a point on the map, you will see the corresponding item highlighted in the GridView. Or vice-versa; you can click on an item in the GridView and you will see its feature highlighted on the map.
In today’s project, we show how to have the WinformsMap control in a MDI form. Using an MDI form with a map background can represent a challenge. You will see in this project the technique to display properly a child form on top of the map. You can also notice how the map is accessed from the child form by plotting points on it from the child form.
This project demonstrates how to create a web-based map using Microsoft ASP.NET MVC 1.0 and Map Suite Web Edition. To meet the requirements of MVC, we inherit the interface IMapInitializer in the controller, which has a function InitializeMap that is overridden in the controller. We then implement the class “MapInitializerHelper” to initialize the map instance.
This week, we decided to publish in the Code Community the project for Map Suite Explorer. You are already familiar with that free Desktop tool that comes with any edition of Map Suite. It is a basic GIS tool that allows you to view your geographic data and its tabular information. It also allows doing some basic manipulation on your date such as building the spatial index. With the source code at your disposition, you can cut time developing your own application by having at your disposal the code for doing common tasks such as loading, unloading layers, building spatial index, changing styles etc. You will also find interesting the legend and see how you can add, remove, move up and down the different layers. It is by far the most comprehensive project in the Code Community to that date. You will need the reference for MapSuiteDesktop.dll and MapSuiteCore.dll (full or evaluation) to run it.
