Throws:
Shows the form as a modal dialog box. When the onclose is specified, the dialog is modal only in the browser.
onclose
When using ShowDialog, the dialog instance is not automatically disposed when the dialog is closed because dialogs are reusable. To make sure that memory is released properly, you must dispose the instance in your code or use the typical using pattern. Dialogs that are closed, but not disposed and not referenced by the application will be disposed by the Garbage Collector when it kicks in.
Modal dialogs suspend the code execution on the server side effectively replicating the full modal workflow employed by desktop applications. However, when the optional onclose parameter is specified, the dialog is modal only in the browser and doesn't suspend the server thread. Which is similar to the typical asynchronous modal pattern used in javascript.
Throws:
Shows the form as a modal dialog box with the specified owner. When the onclose is specified, the dialog is modal only in the browser.
