i am currently using jqgrid on an asp.net mvc site and we have a pretty slow network (internal application) and it seems to be taking
the grid a long time to load (the issue is both network as well as parsing, rendering)
I am trying to determine how to minimized what i send over to
the client to make it as fast as possible.
Here is a simplified view of my controller action to load data into
the grid:
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult GridData1(GridData args)
{
var paginatedData = applications.GridPaginate(args.page ?? 1, args.rows ?? 10,
i => new
{
i.Id,
Name = "<div class='showDescription' id= '" + i.id+ "'>" + i.Name + "</div>",
MyValue = GetImageUrl(_map, i.value, "star"),
ExternalId = string.Format("<a href=\"{0}\" target=\"_blank\">{1}</a>",
Url.Action("Link", "Order", new { id = i.id }), i.Id),
i.Target,
i.Owner,
EndDate = i.EndDate,
Updated = "<div class='showView' aitId= '" + i.AitId + "'>" + GetImage(i.EndDateColumn, "star") + "</div>",
})
return Json(paginatedData);
}
So i am building up a json data (i have about 200 records of
the above) and sending it back to
the GUI to put in
the jqgrid.
The one thing i can thihk of is Repeated data. In some of
the json fields i am appending HTML on top of
the raw "data". This is
the same HTML on every record. It seems like it would be more efficient if i could just send
the data and "append"
the HTML around it on
the client side. Is this possible? Then i would just be sending
the actual data over
the wire and have
the client side add on
the rest of
the HTML tags (the divs, etc) be put together.
Also, if there are
any other suggestions on how i can minimize
the size of my messages, that would be great. I guess at some point these solution will increase
the client side load but it may be worth it to cut down on network traffic.
