Hi,One of our client reports a issue where the data in the UltraGrid doesn't show unless the user mouse hover over the grid, or scroll the grid. We have UltraGrid on the tab that displays patients data. The tab also has an option panel and other controls. When the client switch between different patients, the data on the options panel and in the grid is refreshed to show the current patient data. Randomly and intermittently when they switch to a patient, data will be missing from the grid (but the options panel and other controls display correctly). Then if the user hover mouse over the grid and moves the mouse, the data appears, as if the mouse movement cause the UI to render.Client accesses the application through Citrix, they said the issue only happened through citrix. We haven't been able to reproduce the issue in house yet.I've attached screenshot.The UltraGrid Version=13.1.20131.2060Client didn't have this issue with older version of the application which uses much older version of the UltraGrid.Please let me know if you've seen this issue before and if there is any resolution.Thanks,Ying
Hi,
we also faced the same problem but with UltraGrid Version 16.1.20161.2088
The workaround for our application was to catch the AfterRowRegionScroll event of the grid and do a grid.Refresh();
It doesn't affect the performance of loading data.

I have the same issue with a Windows Forms application using Infragistics Version 15.1.
The symptoms were seen throughout the program.
It wasn't clear where to apply the suggested fix:UltraControlBase.UIAutomationForCodedUITestingEnabled = false, and where I did apply that setting, it did not resolve the problem in my app.
Furthermore, I do not use UITesting or make any direct calls to UIAutomation that I am aware of, though I noticed that a reference to the dll's were added to the project.
I did find my own workaround though.
My base control is a usercontrol with an UltraPanel container that is used to host the other usercontrols inside it.
I changed this top level UltraPanel to a regular Windows Panel and the problem disappeared.

I was told in April.
That's great. Do you know when the service release is expected?
There is a workaround:Set UltraControlBase.UIAutomationForCodedUITestingEnabled to falseOfficial fix will be in the next service release.
