Hi everyone,
I have a console application and I want to export a RadChart to image, I found this thread and I did as mentioned in the solution, the problem is that when I have over 50 input, the exported image appears very poorly.
In your example you put 4 values per serie
if you try with 100 values per serie you can notice that the exported image does not display correctly.
I think that the issue is from the width of the rectangle in ExportStyle.

Hello,
I have a window where I need to show 6 charts and that window can change its size, as the window gets smaller, the labels on the horizontal axis start disappearing as you can see in the attached image.
This is the a sample code:
Is there a way to avoid this behavior?
Maybe make smaller the bars instead of disappearing the labels.
Thanks in advance,
Alberto

How can I hide all axis labels and ticks and still have the zoom bar showing?
Setting the axis visibility hides both, setting labels and and tick colors to transparent still incurs a perf penalty.

Please let me know if anyone can help me.

Hello,
I’ve started my RadControl a few days ago and I’am delighted by the number feature and mature design of the components.
However I've also just started with WPF UI Development, so my learning curve is still steep and maybe you can help me with a Data Binding problem/misunderstanding of mine:
I've got a RadGridView (inside a Data Template) in an MVVM Application, and I’m trying to bind an Observable Collection to a GridViewData Column. Please take a look at my following Models and View-Models (I’ve stripped out unnecessary code):
I want to put these Collections in one RadGridView (as you can see, I just want the Values member from the CalendarWeek in the Column).
I have tried many approaches I have stumbled across the RadControl Help, Forums or on StackOverflow, but none seems too work (or I missed the right combination) for me.
What are your preferred approach here?
Hierarchical? Master Detail Binding? Creating my own GridViewDataColumn Template/Style?
Thanks a lot and happy Holidays for all of you :)

Hello!
According to demo WPF->GridView->Appearance->Data Formatting I can set DataTemplate as CellTemplate.
Everything works fine. But what should I do if I want my DataTemplate fill cell?
For example, this code will show me empty cell:
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<Grid Background="DarkMagenta"/>
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
instead of filling all empty space.
