Column Group Clear() is broken!

[Chris]

Issue #1

This statement: this.dgrParameters.ColumnGroups.Clear();
Causes this failure: Value does not fall within the expected range.

Issue #2
If there is only 1 item in the collection and you execute this statement:
this.dgrParameters.ColumnGroups.RemoveAt(0);
It causes this failure:
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Issue #3
When you add and then remove items from the column groups list the grid header does not properly refresh.


Why are we constantly being plagued with these post release issues???
Where is your quality control?
PLEASE TEST YOUR WORK!!!!!!!!

This is EXTREMELY frustrating and quite frankly makes us want to change vendors!!!!!!!!!

I CAN ASSURE YOU WE WILL BE CONTACTING YOUR CORPROATE OFFICE TO DISCUSS WHY WE ARE CONSTANTLY BEING PLAGUED WITH THIS UN-ENDING BARRAGE OF POST RELEASE ISSUES...

Hello Chris ,

Please excuse us for the inconvenience caused. Initially  the column groups were intended to be used declaratively in XAML only without changes run time . However we have got a few requests to change this behavior so that groups can be manipulated on-the-fly. The good news is we have this already implemented in our production code. There is an internal build scheduled  for tomorrow. The fresh binaries containing a fix applicable to your scenario will be available for download tomorrow in your account . Again please accept our apologies for this trouble.

In case you meet any other issues with RadGridView do not hesitate to contact me . We are doing our best to address such critical problems in a timely manner.

Thank you for responding. I now see 2 hot fixes both with the same relase notes and two different sizes!!!!!

Which one do I download and install??????

Does this hotfix also address the issue with adding and removing column group headers not refreshing the grid properly?

HELP!

[Chris]

I downloaded and installed the hot-fix. It still appears to be broken....

HELP!!!!!!!!!!!!!!

Hi Chris,

*[I am duplicating this response as I believe it covers the issue in your relevant bug report]

In order to make sure the latest internal build contains the proper fixes , I have prepared a small test project.
Please find it attached. It has a few buttons to add / clear column groups runtime.

In case your problem persists with this LIB , please let me know how to modify the test app in order to expose the issue. If I am able to reproduce the issue locally I will personally take care for the proper fix to be added for the very next LIB ( the next Tuesday ).

The three issues that Chris had raised are working perfectly now but there is another issue that I encountered:

Horoizontal Scrolling of Column Group Headers has stopped working. It was working before the current patch but somehow not working in the current build. I've a small sample app to attach but not sure where to send. 

I'm using the following build : 2011.3.1406.1040
