beforeLoadComplete in IE8 and above

[zorgozParticipant]

Hello,

I need to add some calculated columns in a virtual mode scenario. First I followed the instructions described here. But it did not work in Chrome, neither in IE11. I discovered, that during virtual scroll, the records array was not indexed from 0, but from actual index of the record, from example from 1110 to 1125. So I had to use Object.keys to be able to traverse the array. This is workig just fine in Chome and IE11, but the feature is supported only from IE9 upwards.
I have no IE8, but when switching working mode of IE11 back to IE8, I realized, that the indexing is from 0 again. So I added both approaches in may code, hoping that it will solve the issue.

Now, my problem: in IE8 (IE11 swithced back to IE8 working mode), even if I return the records array as it is passed to the method, the grid is not populated at all.

What can I do?

Hello zorgoz,

There’s no difference in the virtual scrolling implementation from browser to browser. I would suggest you to learn how to use the feature from the Virtual Scrolling demo on our website or the demo inside the phpdemos folder of the download package.

Hello,

Well, this is no help at all. Since I have consulted all your demos, and topics here. You can’t deny the facts I see in the debugger. It is working in many browsers in the same way, but not in IE8 – and the server side is the same. The browser-specific difference has to be in your code.

As I see, I don’t have any other option but to find the bug…

Hi zorgoz,

I do not know what facts you see in the debugger. If you want to prove that something is wrong on our side, then provide a sample. The facts are that Virtual Scrolling works correctly in IE8 or other browsers when it is implemented correctly by the User i.e the “rendergridrows” function is created in the documented way.
