Scroll grouped listview, crash

Question

Hi All,

I have a grouped listview, if there are much items, it will crash while scroll it many times.

 the error thrown from function getClassName, I find that the "e" is null, so e.className failed.

functiongetClassName(e){

varname = e.className || "";

.....

Get the call stack as below, anyone can help this? Thanks.

Answer 1

I am currently having this same issue.  Did you make any progress?

Answer 2

No any progress till now, it is strange that no MS dev reply my question.

Answer 3

Ya and I'm suprised there haven't been anymore people with this problem either,  But Ill keep you updated if I find any solutions.

Answer 4

I changed our design, but it appears to have been caused when I updated a listviews indexOfFirstVisible attribute. My guess is it wasn't rendered by the time I was trying to scroll to that position.  Good Luck.

Answer 5

Any update on this issue. Because I am facing a similar problem. Did anyone get a workaround for this? 

Thanks!
