WPF beginner question

Hello

I am learning WPF, and created a <Button> element with a click event as:
<Button Click="doThis" Name="Button1"/>

Now my question should Orcas create the doThis() handler or I should
generated myself in the Page1.xaml.cs file?

Thanks,
Elias

I haven't played around with Orcas, but in VS2005 you have to create the
handler yourself.

It's an easy interface:

private void doThis (object sender, RoutedEventArgs e) {
...your code...
}

If you're not sure about the arguments' types (it depends on the type of
event), the easiest is to write the (temporary) code as follows:

Button myButton = new Button();
myButton+=<TAB><TAB>;

where <TAB> is pressing the tab key. Visual Studio will create the event
signature for you. You can then remove the temporary code.

LOL...I was thinking about suggesting that. I'm glad I'm not the only
person that does that...

:-) I am all about pragmatic programming... if it works and speeds up
writing code, it's good to me!

Hi Guys,

That is what I actually do.
Actually, you don't have to (re)define a Button from the code, cause
it is created when you define it in the XAML code.

But I was wondering if VS would also create the handler from me when I
say that a button has a Click handler (in the XAML code directly).

Regards,
Elias

In the current state, VS2005 cannot do this, no. WPF is an added
technology and the editor you use to type XAML is actually the XML
editor, with limited abilities.

I am not sure if VS2008 will allow this either (probably it will, since
Cider (the visual editor for XAML) will be better than in VS2005.

There is an alternative: Use Expression Blend:

- Open the project in Blend
- In the Project browser, right click on the solution and choose "Edit
in Visual Studio". This will start Visual Studio as your code editor.
- In Blend, select the control you want to add an event handler to.
Choose the "Properties" view on the right hand side, then select the
"Events" view (that's a small "lightning" button on the right top side
of Blend).
- Choose the event you want to handle, then double-click in the text
field next to the event.

This will switch to VS2005, and create the event handler for you. The
XAML code will also be updated to hook the event.

I recommend all my developers to have their projects open in Blend AND
VS2005 at the same time. It's a very nice way to work.

Good luck!

Thank you for the tip Laurent.

So this is the right newsgroup to post my future WPF questions?

Microsoft is trying to push users of WPF to rather post in MSDN:
http://forums.microsoft.com/MSDN/Sho...D=119&SiteID=1

This website has more traffic than the usenet group, and is monitored my
Microsoft.

Good news - you no longer need to resort to tricks to get your event handlers
written for you. From Beta 2 of the Visual Studio 2008 product onwards, the
WPF designer (Cider) supports double clicking on the design surface to create
default handler, and XAML intellisense to create non-default ones.

You can get Beta 2 here
http://msdn2.microsoft.com/en-us/vstudio/aa700831.aspx

If you have feedback on the WPF Designer (aka Cider) in Visual Studio 2008
I'd encourage you to send it to the forum here:
