TableListBox with XML element - size limit

Hi, I encountered an issue while working with TableListBox that uses XML element for storing data. I’m using the code from TableListBox tutorial (without changes) and when the file from which it reads the data is larger than some threshold (to be specific 60kB) a read acces violation exception is thrown. Here I add the StackFrame:


Update: I noticed the threshold seems to be in terms of rows not in terms of the size of the data.
I also uploaded the data I’m working with. With this file it works without a problem but if I add to this file one more item the exception is thrown.
Has anyone encountered similar issue?
