- Installed .Net 3.5 (I already have vb6, vs 2003 pro and vs2005 dev but haven't moved to 2008 yet).
- Installed Blend 2.5 March 2008 preview
- Started learning the hard way....
Ok I should have read a load of tutorials, poured over examples etc but what I choose to do was play all the samples and then start trying to animate an ellipse. This is when it all started to unravel. Here's what happened:
- I started MS Expression Blend and added a Silverlight Project (VB.Net version).
- I drew an ellipse.
- I added a storyboard, moved the ellipse and stopped the recording.
- I pressed play and nothing happened so I moved the little mark in the timeline.
- With the ellipse animated I added a button.
- I spent 30 mins trying to connect the button click to the ellipse anim.
I turns out that the help files description of "Add or remove a trigger" no longer applies to this build of Blend when working on Silverlight projects (see: Where is the Triggers Pallet in 2.5 March). So I attempted to hook the event manually as suggested in the last post in the thread but in Vb.Net, this resulted in:
Page.XAML.VB
Imports System
Imports System.Windows
Imports System.Windows.Controls
Imports System.Windows.Media
Imports System.Windows.Media.Animation
Imports System.Windows.Shapes
Partial Public Class Page
Inherits UserControl
Public Sub New()
InitializeComponent()
End Sub
Public Sub Mouse_Clicked(ByVal sender As Object, ByVal e As MouseEventArgs)
Call storyboard1.Begin()
End Sub
End Class
This caused a "type 'MouseEventArgs' is not defined" error. It turns out that it should be defined as RoutedEventArgs (see Create a new event handler method).
The end result is below (21kb wmv from Windows Media Encoder 9)
That's it for now.
