Sometimes it's useful to show the name and version number of your application on a screen. Whilst you can do this by hard-coding the information (and remembering to change it every time you deploy), this is not a very efficient way of doing it.
There are code samples around that show you how to get the information dynamically, which avoids the maintenance problems, but hey, this is Lightswitch, life is supposed to be easy, right? Who wants to write code when you can just use a control?
The Application Information does this for you. Simply set the control type of a static property to Pixata Application Information, and then set the properties as you wish. There are only two of these, so it's pretty simple...
The Font Style property is the same as you get in any text-based control in Lightswitch, and enables you to choose what style of text size, etc you want.
The "Information to be displayed" property allows you to choose what application information the control should show. This can include a combination of the application name and version. When Lightswitch builds your application, it gives it a version number that has three parts. The major and minor parts are set by you in the project property pages...
In the example above, the version is at the default value of 1.0, but in reality you should change this every time you deploy. In addition, Lightswitch adds a build number, which you cannot change, and will increase by one every time you deploy.
Here you can see the control on a screen, showing the application name and the full (ie major, minor and build) version number. The font style has been set to Heading1.
