OnTextChanging Method (DropDownEditor)


GrapeCity.Win.PluginInputMan Assembly > GrapeCity.Win.Spread.InputMan.CellType Namespace > DropDownEditor Class : OnTextChanging Method
An System.Object value that indicates the event sender.
The TextChangingEventArgs instance that contains the event data.
Raises the TextChanging event.
Syntax
'Declaration
 
Protected Overridable Sub OnTextChanging( _
   ByVal sender As Object, _
   ByVal e As TextChangingEventArgs _
) 
'Usage
 
Dim instance As DropDownEditor
Dim sender As Object
Dim e As TextChangingEventArgs
 
instance.OnTextChanging(sender, e)
protected virtual void OnTextChanging( 
   object sender,
   TextChangingEventArgs e
)

Parameters

sender
An System.Object value that indicates the event sender.
e
The TextChangingEventArgs instance that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate.

The OnTextChanging method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

When overriding OnTextChanging in a derived class, be sure to call the base class's OnTextChanging method so that registered delegates receive the event.
