I wrote a simple application:
<Button MouseDown="buttonX_MouseDown" ... />
and C# code:
private void buttonX_MouseDown(object sender, MouseButtonEventArgs e)<br />
{<br />
if (e.RightButton == MouseButtonState.Pressed)<br />
{<br />
...<br />
}<br />
else if (e.LeftButton == MouseButtonState.Pressed)<br />
{<br />
...<br />
}<br />
}
However, this event fires ONLY when I press right mouse button. It does not fire (the whole event) when I press left mouse button over this button. Why?

Because the Button is eating the left mouse button down.
I think if you set up a handler manually for the event in code, there is an property that you can set to tell WPF that you want to receive the click event after is have been marked as HANDLED.
Just look into wiring up routed events that are HANDLED.

how can i set shadow for a wpf form (winxp)
i want to design a startup form with shadow over desktop
|
|
|
|

for just the start up form, you can use a borderless window, then use a bitmap effect on the window root element.
So if you root element was a Grid, you would apply the bitmap effect to the Grid.
There is a good bit of example WPF code out there that explains creating a transparent, borderless (a window without chrome).

this way is basic and not specified to wpf
is there any new properties that make shadow for controls in wpf?
|
|
|
|
|
Yes.
BitMap effect.

Look into WPF DataTemplates. You can use a TemplateSelector to select different templates based on some code in the TemplateSelector or you can use a DataTrigger in the DataTemplate to change which icon is displayed.

Thanks Karl. It worked for me. One more question, can we have separate icon for each node? I am asking because currently I am assigning image depending upon the HasItem property of treenode. In future I will like to show different icons for each node. Is it possible?

Yep. 
Use one of the two previous methods I gave you and test against the data that is bound to the TreeV Item. Then display the icon you want.
WPF makes things like this very simple for developers. Got to love WPF. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Thanks Karl for reply. Yes it can be done using different properties, for example check the tag value and set the image. Now I am crating a generic user control and I want these images should dynamically get assigned. So, application1 will like some another icon at root level and different icon at child node level, similarly application2 will like to use some different icons. What I will like to do is let the application using my control set the images programmatically. How can we do this?

This a SUPER easy in WPF.
Read up on Styles and ControlTemplates. There are a lot of WPF articles here on Code Project that cover this topic.
This is one of the foundational powers that WPF delivers.
You can simply write one Style, place it in application scope and all Tree controls can use it.
The possibilities are endless.

I`m trying to play a short sound using MediaPlayer class. I`m using the following code snippet:
MediaPlayer mp = new MediaPlayer();
mp.Open(new Uri(@"C:\...\Dom.wav"));
mp.Volume = 1D;
mp.Play();
It goes well, but when I try to play this sound in my form (where I have several endless transformations), it never gets played. I suppose that the reason is that it is to be played on the same thread that UI works. And as the UI works all the time (because of endless transformations), my .wav never gets enough CPU to be played. So I tried to launch it on separate thread. It didn`t help either. The only solution I found is to add a sleep after this:
MediaPlayer mp = new MediaPlayer();
mp.Open(new Uri(@"C:\...\Dom.wav"));
mp.Volume = 1D;
mp.Play();
Thread.Sleep(1500);
But this looks terrible. Could anyone give me another solution?

If you just want to play sound, look into the managed DirectX classes instead.

Don`t tell me it can`t be done using MediaPlayer class...

I don't know, but I know that class is slow, and it seems to me like overkill

Using so enormous technology as DirectX to play 5-second simple sound is even bigger overkill. Thanks for advice however.

Not really - it's just using built in stuff that is there already.

You need to install .NET 3.0, which will give you what you need to build a WPF app. There are also add ins for some IDE support.

Yes, it is. But, that's what comes with VS2008. I'm not sure if there's a WPF VS2008 Express Edition, otherwise, you'd need to buy it.

Of course not. If it did, who would upgrade to VS2008 ?
