otinanism7 months later, still no fix for this bug. And no fix for any other bug concerning virtual scrolling. Can someone please let me know if anyof them will ever be fixed?1
otinanismI keep reporting bugs and I have not seen one bug fix yet. There is not really support for jqgrid is there?
otinanismWrong again, it is the line 773: var scrollTop = grid.scrollTop = grid.bDiv.scrollTop;
that seems to be the problem. in IE8 this value is 0 where in FF and IE7 it is not.
otinanismI just realised that in IE 7 the bug is not happening! At least not when running from IE9 with IE7 compatibility mode. So it's on IE8 or greater and Chrome 11 where the bug occurs. What I was able to find is that in line 775 of grid.base.js file the ttop variable is calculated differently in FF, IE7 and differently in IE8. This variable calls the position() function of jquery, so I suppose the bug has something to do with jquery? Could anybody find a workaround please?
Thank you again.
otinanismDoes anybody has any idea on how to check what is going wrong? I have been struggling with this for days now.
Thank you
otinanismTo the maintainers of jqgrid:
This is the third critical bug I have reported concerning Virtual Scrolling.
I do not understand why there is no support for this functionality of the grid. I understand that this is a free plugin, but you should probably remove the virtual scrolling as a feature of the grid. It clearly is NOT ready.
Just mention it as a beta or prototype or trial feature, or whatever.
I am not saying you have to support it, I am saying you should not misguide people (http://www.trirand.com/jqgridwiki/doku.php?id=wiki:features)
Sorry if I sound pissed but I am, since I feel misguided.
otinanismThank you Tony. Any idea for a workaround? I have been studying the code since there is no way I can replace jqgrid with anything else right now (deep into development phase).
otinanismTogether with the other serious bug in jqgrid virtual scroll, this is a major issue. It is beyond me why nobody is replying, just to aknowledge the bug, I am not even asking for a solution right now. Or if you are sure this is not a bug why don't you just say this? Both bugs are visible in your demos!!
otinanism..And it is happening only on scroll up. Still no luck with this issue. Please someone from the dev team, just aknowledge that this is something that needs to be fixed. I am not asking for a fix, I am asking for an answer! Two months has passed and no feedback. Please!
otinanismYes, this is ONE MORE bug of jqgrid true scrolling. Together with all the other ones I am really disapointed with this feature. Unfortunatelly, I am deep into development with it so it would not be easy to scratch it and use something else.
True scrolling is too buggy for use in production.
Multiline not suppotred. This is unacceptable.
Is there any workaround??
otinanismI don't understand why nobody is replying, even if it is just to confirm that this is a known bug
otinanismPlease some feedback, this is extremely critical.
otinanismHi,
I do not see how this is working. On the demo when you scroll down page by page, the pages are not unloaded. When you scroll up the pages ARE unloaded.
Also on my grid, when I scroll up the pages are unloaded.
But there is need to unload pages on scroll down also, the performance degrates very fast if the pages are not unloaded.
Is there any solution for that?
Thank you in advance.
otinanismHi,
tony, you say “The purpose of updateGridRows is to update data with equal id's and to to add new one.”
Do you mean that if it finds the row it updates it and if it does not it adds it to the grid? Because I tried using it and it does update correctly, buit it does not add new row if id is not found. Is there any functionality fo this ( update or add if not found at the same time)?
Thank you in advance.
otinanismIt does not work correctly in IE either. At least not in IE8.
