Ahmadreza A,

I may do that some day, thanks! For now, please have a look at the WP7Contrib project (wp7contrib.codeplex.com); it's on CodePlex and they've incorporated LowProfileImageLoader into their code.

Hope this helps!

Would you please put this source code somewhere like github or codeplex

I want to fork this and add new features. I want it to be visible where is is originated from

Ahmad

sudhir1986,

You might be interested in the PlaceImage control I wrote for this purpose: blogs.msdn.com/.../know-your-place-in-life-free-placeimage-control-makes-it-easy-to-add-placeholder-images-to-any-wpf-silverlight-or-windows-phone-application.aspx

It's not integrated with LowProfileImageLoader, but you might be able to reuse some of the same ideas.

Good luck!

Mido,

The link near the bottom of the post that says "[Click here to download the compiled PhonePerformance assembly, sample applications, and full source code for everything.]" should give you everything you need.

Could you tell me where I can find the source code of PhonePerformance 1.2.1, please?

Thank you!

Yaurthek,

It sounds like there may be some unusual things going on in your scenario - but it's great to hear you found a resolution. Thanks for sharing!

Hello,

I gave your LowProfileImageLoader a try, and it is pretty effective!

However, I sometimes get a NullReferenceException line 149 (the Uri is null) while binding on a collection of Uris, some of them being null...

I first thought you didn't handle null Uris at all, but if I use a collection of data with only null Uris, its seems to work without any exception.

I don't fully understand the problem, and even less your code, but I somehow found a fix:

I just added the following lines at the beginning of the OnUriSourceChanged(...) method. (after the uri initialization)

if (uri == null)

{

image.Source = null;

return;

}

Its seems to work as expected now.

David,

Setting Bacground="Transparent" on the Border element fixed the problem. Thanks a bunch!
