I came across with an issue, I'm using you example and I added a combobox, also i'm using a bussinnes objects as a source instead of a xml source, the thing is that when I select a item in combobox my bussines object updates, but the TreeListViw don't..

Do you know something that could help me..

thanks

Hi,

As far as I found the best TreeListView for WPF.

thx for sharing.

But I (a beginner in wpf) have a problem.

How to change the headerstyle in the themes.

It would be great if someone can show me a how to

may be with an example.

thx

Great to find your project and I am wandering whether I can use your library to compare two sound files? Tks.

Fantastic work! I tried several other TreeListViews before encountering this one, but this one seems to be the most feature-complete. I love the way that scrolling is implemented - the header always remains visible. Good job.

I have downloaded your app. It works on some machines but does not work on other. I have dotnet framework installed on all machines. Does you application have any special dependencies?

This is by far the best looking sample for an audio spectrum visualizer that I have found. However, I am completely puzzled by following line:

float v = (((int)sqrtf(im * im) / FFT_LEN/2) % 100);

I realize the progress bars display have a max of 100, but why % 100? Conceptually, it seems like that would give arbitrary values for the peak, since the numbers are often greater than 100, sometimes by orders of magnitude.... However, as I said, this is a darn good looking equalizer, so it works fine despite that I don't understand it...

For those concerned about performance, you'll notice that since the block size is the same every time the FFT is called, so you can store an array of the angles for fSin1, fSin2 and fCos1 and fCos2.

The same issue there's on IE. The cpu load is due only for the bar visualization and I think that the major load is on animation. There are two storyboard for each bar, restarted at least 12 times per second. The Silverlight engine try always to render fast as possibile and so it uses all the core. Try to change the MaxFrameRate to a small value, for example 15.

I'll try to work on performance in the future. This is the first release :-)

Hi guys,

the control works as any other selection control. For sorting, filtering and so on you have to work with CollectionView and automatically the data will change on the control.

The single selection is due to TreeView base class. To change this behavior, you have to override the IsSelectedProperty on TreeViewItem and not notify the control owner when a selection is done. Then, to get the selected items, you have to enumerate all items and read the IsSelected property
