I'm trying to use my own safe observable collection as the Item source for the grid.
What I've done for testing purposes is this:
1. Open a new thread
2. Create a lot of data in that thread
3. Clear the item source that's already binded to the radGridView (the collection being cleared is done in the thread, the call to CollectionChanged is invoked to the dispatcher)
4. add all of the items in the disconnected list to the ItemSource, every addition makes a separate invocation to the dispatcher to call CollectionChanged.
At a random point during 4 I'll get the exception, could be on the first addition could be on 200th (let's say I have 1000 items in the collection), what I've found by logging everything that happens in my observable collection is that the random point is the one after the grid calls GetEnumerator, I've made sure that the enumeration has ended before I touch the collection by using a reader writer lock and the addition only happens after the enumerator is disposed.

Hello,
I am using the WPF RadRichTextBox as an email editor to reply to inbound emails. Like in most email applications, the body of the inbound email is included as quoted text within the email editor.
I would somehow like to prevent the quoted text from being checked for spelling, both by the inline red squiggly lines and by the spell checking dialog. I am already providing my own implementations of the ISpellChecker and ISpellCheckingDialog interfaces.
One possible solution I considered would be to load the quoted text, and then silently run the spell checker and "Ignore All" for each misspelling prior to allowing the user to edit the reply. The down side to this approach is that if the original email contains any misspellings, those words would be added to the black list of Ignored words, and they would not be identified as misspelled if the user types them in the reply.
Is there a better solution for this issue? For example, is there a way to mark a DocumentElement to suppress the spelling inspection of any text it contains? Or is there a way to ignore a specific instance of a word instead of Ignore All?
Any help is greatly appreciated.
Thanks,
Evan

Hi Telerik Team,
I would like to know if there is a way to dynamically change the width of the columns in the scheduleview, in order to zoom in and out horizontally.
In the end I would like the users to use a slider that would increase or decrease the width of the columns, until they all fit in the window without horizontal scroll, even if the appointments are too small to read their content.
Do you understand my need ?
Can you help me doing it ? I've searched a way, but found nothing for the moment.
Thank you !
Pauline

Hello!
I would like to publish my WPF application and I would also to pack all Telerik's libraries (for components which I used) into one library (so I have less number of dll's files).
Can I do this?
If yes - how?

Hello,
Prior to updating with Q2 and Q3 2012 (at once), we had a RadCartesianChart BarSeries that functioned exactly as desired. The graph displayed grouped bars from two series by month, regardless of year. Now, the cluster functionality is no longer working. It seems that the year is not disregarded as it was before, so each month is listed twice.
Can you please help with how to restore the clustered display by month?
For reference, here's the relevant XAML:

Hi,
We are currently implementing a piece of software where we use the MVVM pattern. Most of your demos are mostly implemented in code-behind. Hence, it becomes hard to know if they are suitable for MVVM.
Can you please provide a list of which of your RAD controls are suitable for MVVM? E.g. RadDiagram?

I've enabled the text search capability with setting IsTextSearchEnabled to true. This works fine, when searching children nodes of the currently selected node. However, the text search does not jump to the next sibling node if the text is not being found in the current node. Is there any way to force searching in the sibling nodes?
Example:
If the current node is "A" a text search for "A1" will be successfull, but searching for "B1" fails.
- A
A1
A2
- B
B1
B2
Thanks,
Michael

Hi All,
I'm new to WPF but trying to work through this Book Control. Could somebody please give me a quick code example on how to get access to the objects I play on the page, for example if I put a button on a page. In vb.net code how do I get access to that object if I wanted to change its label. I take it I need to first get the RadBookItem which should be the page I am on and then somehow use an object collection to get access to the child objects on that page but I cannot see anything like that in the intellisense for RadBookItem ?
Kind Regards
Ken
