Public Event SymbolFormShowing As SymbolFormShowingEventHandler
The SymbolFormShowing event's data class is SymbolFormShowingEventArgs. The following properties provide information specific to this event:
|DialogResult||Gets or sets the return value of a dialog box. Inherited from ShowFormEventArgs.|
|Handled||Gets or sets whether an event was handled. If it was handled, the default actions are not required. Inherited from ShowFormEventArgs.|
|Parent||Gets or sets a parent of the form being shown. Inherited from ShowFormEventArgs.|
|ViewModel||This member supports the internal infrastructure and is not intended to be used directly from your code.|
Handle the SymbolFormShowing event to perform any actions prior to the Symbol dialog being shown. For example, you can substitute the standard dialog with a custom one and set the ShowFormEventArgs.Handled property to true, to prevent default event handling.
