Hi,
I have a grid with 200 rows and 200 columns. In IE8 the grid is very slow. In IE7 or Firefox the grid works without performance problems. I have test it with the latest 2009 Vol.1 sersion and with the 2009 Vol 2. version.
I can not see that this problem is fixed.
Can you help me?
Regards
Marco
Marco,
Is this regarding WebGrid or WebDataGrid?
You'd originally posted this as a reply to a thread in the WebGrid forum. I also see that you have a support case open (case number CAS-35071-DFDZ4S) which is listed as for WebDataGrid. Which one is correct?
Either way, 200 columns is a lot of data. That's 40000 cells, each of which will have its own HTML elements and client-side object model (CSOM) objects, above and beyond the content of the cells themselves. That's also quite a lot of data for any user to attempt to absorb.
There are options available for limiting how much HTML is generated on a row-by-row basis, which varies depending on which grid you're using. You will likely want to reduce the number of columns in addition.
Even with all this in mind, this is something that we'll need to investigate in more detail, since you're not seeing the same performance issues in IE 7 or Firefox. This will require in-depth research, which is best done through the support case you've already logged.
We've experienced a similar performance issue here: the page loads quickly (including the grid data), then seems to hang for a few minutes - only in ie8.
We seem to have resolved it by NOT running the website in compatibility mode. Untick the 'Display intranet sites in compatibility view' tickbox under 'Tools>Compatibility View Settings' and remove the intranet server name from the include list.
This sounds unusual. Most of the IE 8 performance issues I've seen yielded better performance when using compatibility mode than when not, rather than the other way around.
Can you reproduce this in an isolated sample application that we can run and debug? If so, then I recommend that you submit a support request to provide us with this sample application and any other details we need to reproduce this behavior, so that we can investigate in further detail.
