OnMouseEnterElement Method

Raises the Infragistics.Win.UltraComponentControlManagerBase.MouseEnterElement event when the mouse is moved over a UIElement.

Syntax

Visual Basic

'Declaration
 
Protected Overrides Sub OnMouseEnterElement( _
   ByVal e As Infragistics.Win.UIElementEventArgs _
) 

C#

protected override void OnMouseEnterElement( 
   Infragistics.Win.UIElementEventArgs e
)

Parameters

e

A Infragistics.Win.UIElementEventArgs that provides data for the event.

Remarks

Raising an event invokes the event handler through a delegate.

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

Example

In addition to the standard mouse events (i.e. MouseDown, MouseMove, MouseUp, MouseEnter, MouseLeave etc.) all PLF based controls expose 2 new events called MouseEnterElement and MouseLeaveElement.

The following code writes the type of each element as it is entered and exited to the output window.

Visual Basic

Private Sub UltraGrid1_MouseEnterElement(ByVal sender As Object, ByVal e As Infragistics.Win.UIElementEventArgs) Handles UltraGrid1.MouseEnterElement

    Debug.WriteLine("Enter Element: " + e.Element.GetType().ToString())

End Sub

Private Sub UltraGrid1_MouseLeaveElement(ByVal sender As Object, ByVal e As Infragistics.Win.UIElementEventArgs) Handles UltraGrid1.MouseLeaveElement

    Debug.WriteLine("Leave Element: " + e.Element.GetType().ToString())

End Sub

C#

using System.Diagnostics;

private void ultraGrid1_MouseEnterElement(object sender, Infragistics.Win.UIElementEventArgs e)
{

	Debug.WriteLine( "Enter Element: " + e.Element.GetType().ToString() );

}

private void ultraGrid1_MouseLeaveElement(object sender, Infragistics.Win.UIElementEventArgs e)
{

	Debug.WriteLine( "Leave Element: " + e.Element.GetType().ToString() );
