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.


  • Database column type, HierachyId, is now supported
  • Expanding the DropDown on the canvas should also select the control
  • In the generated application, do not allow the current user to be deselected as Administrator
  • Add messages to empty tables in the Admin site
  • On the canvas, indicate invisible columns by displaying their text as light gray
  • Prevent possible security attacks on the generated application(i.e. Clickjacking, XSS)
  • Infer types assigned to properties
  • Allow selecting Connectors as Value for the SetValue action
  • Allow assigning references to the Message property of the Notification Action
  • Improve the performance of the Gallery Editor
  • Allow get and set for the Options property on list controls via scripts
  • Do not delete actions inside of the current Button paths when changing the Buttons of a DisplayMessageBox
  • Changes around setting and deleting of the Application Start Page
  • Toastr error messages thrown by Stadium should be explicitly dismissed by the user
  • Database connection validation not disappearing after correcting it
  • Remove the option to assign Control properties to the NavigateToPage.Destination property
  • Use the ~ to represent the script in a reference breadcrumb
  • The Tables & Views pane of a query should be open by default
  • Rename DataSources to Connectors
  • ConnectionString editor loses focus when testing a connection
  • Add a '+' icon to DataSource node in the App Explorer to add new queries
