Stadium 5.9.2074.6587 is now available

In this release, we redesigned the entire Event Framework from scratch! This new, greatly enhanced, more powerful and easy to use Event Framework gives you the freedom you need to design highly interactive applications, making your users' experience so much better. Please give it a test run and let me know what you think!

The important new features I want to draw your attention to are:
  • Events

    A powerful event framework allowing designers to greatly enhance the interactivity and user experience of their applications. PageLoad and OnChange were added as two new events with more to come in the future!
  • List controls now use JSON formatted data

    DropDown, RadioButtonList and CheckBoxList now use JSON formatted data when specifying static options. By doing this, options can now be re-used simply by reading them from a Static Data file or copy pasting them from one control to another.
  • Static Data

    Include files & images as static data into your Stadium application and use them on certain controls and actions.
  • Selectable Rows in a DataGrid

    The DataGrid now has an optional checkbox column allowing the user to select one or more of the rows inside of the DataGrid. The application designer can then iterate through the selected rows using a ForEach action in a script.
  • Get or set the search term of the DataGrid

    Being able to get or set the searchterm is very useful when navigating away or back to a page where the DataGrid should remember the user's previous search.

Other features and bug fixes we worked on can be seen below.
