Thank you for your question.
To be honest this is the first time I hear about such a problem. I assume this might be related to the ViewState of the grid or page, which means that it should be cleared out at some point. I did a quick check with the official ASP.NET View State article, and they are only mentioning clearing a view state when persisting it manually:
"The second challenge arises because, each time a user visits a different page, a new file holding that page's view state will be created. Over time this will lead to thousands of files. Some sort of automated task would be needed to periodically clean out the view state files older than a certain date. I leave this as an exercise for the reader."
For the second issue, the PFA screenshot
