Telerik libraries - RadControls for WPF Q2 3013 SP1
My Project: WPF desktop application in.Net 4.0 C#.
The problem:
I'm adding rows to the RagGridView through an ItemsSource binding to an observable collection. Whenever an item is added to the collection, the RagGridView control reloads all previously added rows along with the new row. It also re-instantiates user controls from the exsting rows. For example, If I have 20 rows, and one gets added from the collection, the entire 20 rows are reloaded before the new one gets loaded. This makes the GUI get slower and slower as rows are added.
What's worse: When items are added that will be displayed out of the scrolling view, the RagGridView reloads all the old rows and then it eventually (after about 15 items are added that are not visible) goes into an infinite loop reloading all the rows that are not visible. This locks up the GUI and fills up system memory since it re-instantiates user controls. This infinite loop happens in my situation after about 45 to 50 rows total are in the grid control.
Here's the XAML definition of the control:
Here is the stack trace from my RowLoaded callback method while the RadGridControl is caught in the infinite loop:
And here's the stack trace when the control is instantiating my CircularProgressBar user control in the infinite loop:
I have tried turning data virturalization on and off with no change the results. I have used the RadGridConrol with much success in the past, but I'm stumped here. I hope I'm just missing something stupid.
Any suggestions? Thanks.

UPDATE: I re-factored a few things which made the infinite looping go away by using the RowLoaded handler to update values at a friendler time. However, I am still having the problem where all the existing rows are being re-instantiated whenever a new row is added. This does cause a noticeable performance hit. Can anyone give me a clue, please? Thanks.

Hello,
Thank you for the update.
Do you insert new row pressing the Insert key? What is the result if you set ShowInsertRow and use it for inserting new rows?

Rows are added and deleted programatically by using the Add() and Remove() methods in the ObservableCollection class that is bound to the ItemsSource property of the RadGridView. I am doing no direct operations on the Telerik control itself. A single Add() operation causes the control to reload all existing rows.

Hi,

I have tried to reproduce the issue, but I were not able to. You can find attached my test project.
Would you please try modifying it so that the case you describe is observed?
If I can reproduce the issue, I could advise you better.

I understand that you can't help me if you can't reproduce the problem. I've been there and bought the tee-shirt. :)
I'm preoccupied with something else in my project at the moment, I'll get back to this issue as soon as I can and try to make this problem happen using your sample code. Thanks.

Hello Don,
We were able to reproduce the problem and the alternation is the reason for recreating all rows when a new one is added. Fortunately, this problem is addressed with RadGridView.GroupRenderMode="Flat". More information about this mode can be found on our documentation.
Let us know if you have additional questions.

Cool! I'll try it out! Thanks! :D
UPDATE: I set GroupRenderMode="Flat" and that did the trick.
