Hello!
I have a site with C# and JQuery with a big table (28 x 60) in one of the screens. In each cell I can have 0, 1 or more items.
I want to make each item draggable and droppable from one cell to another.
I was able to do so but when I have a lot of items in the table, the droppable function makes my page goes really slow (reaaaaally slow). It gets slow when loading the page (maybe a rendering problem?) and when I try to drag an element.
I've tried to make it work in different ways, like using different controls to activate the drag&drop or activate the drop on mouseover only, but it seem to just not work. If I comment out the drag&drop functionality my site works perfectly fine.
I've tested in like 4 browsers
In Chrome and Opera it goes really fast, no problems at all
In FF it goes somehow slow (5 to 6 second to load the page, drag&drop function works not really fluidly and drop itself takes about 4 seconds)
In IE8 it just doesn't work, it takes so much time that IE8 tell me time has expired.
Not much difference in IE7
I'm talking for about 200 items in the table. When I have 15 or 30 items it works perfectly fine.
This is a really critical functionality for my system... is there a way to accelerate this?
Hope someone can help me out
