Hi,

I have an application built using MVVM pattern and Caliburn, which displays two TreeListView in parallel using Virtualization.
When I set the IsExpandedBinding property, then performances (scrolling down ...) are really bad.
When Tree Lines are hidden, then performances are only acceptable.

I also have another need: the background color of each row should change based on a binding (Status property).
I tried to achieve this with a RowStyleSelector (not sure I should do it like this with lightweight templates) but performance are incredibly bad (Especially when dragging the Scrollbar or when using Page Up/Down keys)...

Note that the test application displays a sample data source but, but be aware that in real life, this data source can be really big. Right now, the TreeListView is simply not usable.

How I improve the performance? What do I do wrong ?

Please find attached by test solution.
You can turn on/off tree  lines and row styles with:

Thanks for your help

I'm using the version 2013.3.1202.40

If a user copies a line (CRTL-C) and pastes it (CTRL-V), there is a problem when one of the column's contents is empty. All contents are shifted “to the left”, simply ignoring the empty column.

So, if we have something like "Text;;;End" it would be pasted as "Text;End"

Hi,

I want to change PropertyGrid font-family, Code like this:


it's not working.

The textblock's(PART_FieldLabelN) font-family is still Segoe UI.

Hello,

I'm experiencing a memory leak when using RadPropertyGrid in a project targeting .Net Framework 4.
I would attach a sample project to demonstrate the issue, but apparently only images can be attached.
I'm able to reproduce the issue with a simple project containing a main window with a button opening a new window with only a RadPropertyGrid, with Item set to a simple POCO object with 2 string properties. The window is not released when closed.

Hi there, 

we are currently working on a wrapper control of your RadChartView RadCartesianChart that contains a DateTimeContinuousAxis. Out clients should be able to modify the FontSize of it, so we bond it to our DependencyProperty AxisFontSize:


When the client changes the AxisFontSize on design or run time something strange happens: https://dl.dropboxusercontent.com/u/55589036/Pictures/Animated%20Screenshots/20150326_1440.gif

Now we experimented a bit to get rid of this problem. In the Changed-Event of the AxisFontSize we tried to re-add entirely new Series with entirely new data plots in a different time range than before. Nothing changes, because your control seems to keep the old labels for resource purposes. We even tried to call UpdateLayout() and InvalidateVisual() in our Update() method that will be called in the Changed-Event.

Now to up the stakes even more we got two other DependencyProperties on our control:
- TimeRange: This enum value (seconds) defines the time range of the DateTimeContinuousAxis. When this is changed we call our Update() method, too, to re-add all Series with new dummy or live plot data in the Changed-Event.
- TimeTickCount: This defines the number of time ticks on the X axis. When changed we calculate the new MajorStep of the X axis and set it to the DateTimeContinuousAxis MajorStep property.

When we change the AxisFontSize and finally change one of the other DependencyProperties it's getting even more weird: https://dl.dropboxusercontent.com/u/55589036/Pictures/Animated%20Screenshots/20150326_1441.gif


How can we fix this problem or bypass the bug? Is there at least a way to force your control to remove and re-add the labels to get rid of this problem?

I am trying to set the Point fill color to Black. DefaultVisualStyle seems to have no effect. 
What is the proper way of applying DefaultVisualStyle in ScatterSeriesDescriptor.Style?

           
I have a check box which allow user to choose whether to display the point Label or not. The Binding IsShowLabel is not working. How can i bind the check box's IsChecked to the ShowLabels property?

Hello,

I see the Timeline control has alternate colors for the intervals, Is it possible to change those colors? I'd like to change them.

Thanks in advance,
