Our WPF app has an internal diagnostic mode that when enabled, will capture the stack trace of the UI thread whenever it has detected that the UI thread has been "overly busy" for a period of time. Analysis of a customer who is experiencing intermittent momentary UI lockups shows that the UI thread is often in the call stack below:
.
at Infragistics.Windows.DataPresenter.CellLayoutItem.GetSize(LayoutItemSize size)
at Infragistics.Windows.DataPresenter.LayoutItem.Infragistics.Controls.Layouts.Primitives.ILayoutItem.get_PreferredSize()
Any ideas on the improving the performance of this method? Infragistics v12.1.
Hello Brian,
Thank you for your post!
I have been looking into your it and it seems that I am missing something from your scenario. Would you please provide me with more detailed information about the functionality you are using? Also would you please provide me with more detailed information regarding the steps that you perform in order to see the UI lock?
Additionally I would suggest updating your application to the latest version of Infragistics control - 15.1, because the performance of the XamDataPresenter has been optimized since version 12.1. Does the issue reproduce with the latest version of the control too?
Looking forward to hearing from you.
Thank you Gergana.
Unfortunately we are unable to upgrade to 15.1 because we have to stay with .net 3.5 so that our clients who are still running XP can still run our product.
I've done additional digging, and found that when this lockup occurs, the user changes an input parameter which causes the xamDataGrid to repopulate with new data. Our code then ends up calling BringRecordIntoView in order to scroll a specific record into view. I've timed the call to BringRecordIntoView, and in certain cases it can take up to 2-3 seconds to complete. When it takes this long, the call stack captured from the UI thread is almost always somewhere inside of get_PreferredSize, which either means that it's being called very very frequently, or that it's a standout slow method, or a bit of both. The call stack is always inside an UpdateLayout call, performing a measure pass.
Asking the question a slightly different way: Do you have any suggestions on how to make a call to BringRecordIntoView faster? I'm not the original coder of this, so it's all a bit new. Is BringRecordIntoView something we should be avoiding and there is a more efficient way to accomplish scrolling a specific record into view? Or can you definitely state that later versions of xamDataGrid have made BringRecordIntoView X times faster?
Here is an example of a more complete call stack:
