CLR Events

Updated over 6 months ago

RadControl inherits from the standard Windows Forms ScrollableControl, and so has access to the principal mouse, keyboard, font, sizing, layout and painting events. These events are captured and passed to the element tree where appropriate. For example, the OnMouseEnter event inherited from ScrollableControl first notifies the RootElement that a the mouse is over the control, then invokes the standard OnMouseEnter behavior from ScrollableControl.

OnMouseEnter

C#

protected override void OnMouseEnter(EventArgs e)
{
    if (!DisableMouseEvents)
    {
        this.RootElement.IsMouseOver = true;
        this.RootElement.IsMouseOverElement = true;
    }
    base.OnMouseEnter(e);
}

VB.NET

Protected Overrides Sub OnMouseEnter(ByVal e As EventArgs)
    If Not DisableMouseEvents Then
        Me.RootElement.IsMouseOver = True
        Me.RootElement.IsMouseOverElement = True
    End If
    MyBase.OnMouseEnter(e)       
End Sub
