I have a large amount of data I want to visualize that comes from an analysis sampling machine. I have a data point every 3 seconds for a total of about 5000 data points. I want to be able to use the timebar to make a selection that I can show in more detail in a radcartesianchart. I can't seem to figure out how to setup Time bar to show the data at all no less be able to make a selection to show in the secondary chart.
Can you please lend some guidance on this? I can't find any other sliding selection tool that would seem to work for this sort of data.

Hi, please tell me how to set 24h time format, and how to modify the IntervalSpans collection in the program code. As I understand it in the Q1 2013 release (version 2013.1.0220) this is possible.

I've made a small example which illustrates my problem:
MainWindow.xaml:
MainWindow.xaml.cs:
The solution attached contains a style on Scrollviewer, which sets the theme, verticalscrollbarvisibility and horizontalscrollbarvisibility.
If I remove the 3 setters from the style, then the example does what I want it to (see jpg-file example A, textbox uses wrap), but when the 3 setters are in the style it kind of destroys the way it is supposed to work (see jpg-file example B, textbox does not use wrap).
How do I get my small application to use the 3 setters while behaving like in example A ?
Thanks

I'm using RadPropertyGrid to display multiple groups of properties & need to know how to: Control the Display Order of the Groups.
I define the PropertyDefinitions in the order in which I want them in in XAML, but the groups don't display in either alphabetical or
the order I define them.
How can I fix this in XAML or code-behind?

Hi may I ask which version of the telerik support Editor Attribute
such as
[Editor(typeof(CustomActionEditor), typeof(UITypeEditor))]
public string FirstName {get;set;}
Also I found out the TypeConverter is not supported in WPF propertygrid as well
Thanks
George

[Editor(typeof(CustomActionEditor), typeof(UITypeEditor))]

I cannot seem to find a method of placing a border around the plotted bar; i.e. each bar on the graph should get a border around it and not entire graph or plot area itself. Does this require custom display handling? I've tried the basic style override and poking in with Snoop, but I cannot locate a place where that border can be changed and the border actually shows.
If manual drawing the bar is required, is there a sample of that hook routine?
Thanks in advance for any insight.

I've read over the documentation for the GridView and it covers copying to the clipboard and it sort of covers pasting back.
My requirements are as follows:
The user can only select the entire row
The user can copy the row's contents to the clipboard
The user can cut the row's contents to the clipboard - this should cause the selected row to be deleted both in the grid and in the collection the grid is bound to.
The user can paste a new row from the clipboard. This should cause a new row to be interested in the grid before the currently selected row (push the selected row down).
I have the copy to the clipboard working. I'm not clear on how to catch the CTRL+X for cut, but I think the implementation should be pretty easy.
Pasting is less clear. Can I just replace the e.Value with a new instance of my entity w/o blowing away the object that was there? Or do I need to do the work behind the scene -
1. create my new instance
2. find the selected instance in my collection and insert it there
3. change the selected instance to my new instance
Any suggestions or directions would be greatly appreciated.

UPDATE: It actually seems that MainWindow binding to itself was causing the issue.. not 100% sure yet but I think you can ignore this ;D
Update2: Yep you can defo ignore this. Or delete the tread if you want ;)
Telerik is causing what seems to be a stack overflow exception in VS2012's designer process. After each compile, the program will hang until I terminate said process after which I have to click 'reload designer' and then it'll work again until the next recompile (or control addition, it seems.)
Here's a project to reproduce the issue:
*links removed*
1. Open MainWindow.xaml
2. Compile
3. Change any text, like in the comment I put at the top
4. Recompile
And then it'll hang.. you can kill the xdesproc process, click reload UI, and it'll happen all over again. I tested this on various systems and it always happens. I *think* the problem is limited to the RadDock but I'm not sure of that.

Hello,
I'm using a radgridview and need to display a column that supports multiple values. For example I have a field "Supported Languages" that can take multiple values such as "English, Arabic, French" .. What type of datacolumn should I be using to display this data? I tried using the ComboBoxColumn, however it requires separate bindings for the ItemsSource and DisplayMemberPath. I'm trying to avoid using concatenated strings. Please advise.
Thanks.
