SearchFormShowingEventArgs is the data class for the following events:
The RichEditControl.SearchFormShowing event occurs before the Find and Replace dialog is invoked. The SearchFormShowingEventArgs class introduces the SearchFormShowingEventArgs.ControllerParameters property that specifies the information to be displayed in the dialog.
Note, that SearchFormShowingEventArgs objects are automatically created, initialized and passed to the RichEditControl.SearchFormShowing event handlers.
This example demonstrates how handle the RichEditControl.SearchFormShowing event to replace the standard Find and Replace dialog with a custom dialog.
