Ajax slowing my search???
-
I wasn't sure where to put this dilemma, but here it goes. I have a web application wrapped around a state machine workflow that allows the user to pick search parameters from one content pane and then displays the results in the parallel pand via a gridview. I've wrapped both panes in and am using ajax extenders (Calendars and Watermark) in the search pane. I also have the search parameters saved into a Dictionary object. Unfortunately this is slowing down this portion of the application to a crawl. I'm at a loss as to what is causeing the delays, which happen both on ititial page load and when search button is clicked. I'm using some ajax extenders in other portions of the application with no detriment. I would provide code samples if you think they'll help, just ask:) Any suggestions or leads would be much appreciated. Thanks,

AJAX means I'd have stuck with the ASP.NET forum ( where you've also posted this ) Perhaps your code is making too many AJAX callbacks and that is slowing it down ?

I was maybe thinking that the ajax may have been slowing down the Dictionary of search parameters, the search inputs first try and get any previous parameters when the page is initialized. Sorry for cross posting, I was just trying to cover my bases. Thanks for the response, I'll look into it. :-D

How do you build up the rows in your grid? Do you create an array of rows and add them all at the end, or do you add one at a time? I've seen codes adding items to DataGridView one at a time and I think the grid does some 'OnAddedItem' handling like trying to refresh etc because when I changed it to adding arrays of data instead, the processing time was cut down to 1/3d. -Larantz

I retrieve a Data Set from a database table via NetTiers. How did you handle populating the GridView? Using the DataBound to create array, then ItemCreated? Thanks for the insight though.

Could be viewstate "bloat". Are you using firefox with firebug? If so you can check out the http requests and responses in the console window and see what's being passed back and forth.

Ok.With DataSet I don't think the row generation is an issue.

Well in a normal case I'd use BindingList to handle the populating of the grid. The example I was refering to before was initially just building up string[] arrays with column values and then adding them to the grid. As a quickfix I just changed that into creating arrays of finished DataGridViewCells and adding the entire array to the grid. If I had the time, I'd go for a BindingList though.

http://www.tellus-software.comNice! Thanks for the tip. I've not had the opportunity to try using a BindingList yet, I'll have to give it a go. Cheers :beer:

I have all the AJAX extensions set to disable ViewState already, but thanks.

Is there a way to do this in IE? Cheers :beer:
