Treeview Menu loading slow10/25/2006 3:16:00 AM

0/0

I am using the treeview control adapter and when I view it locally on my computer with Firefox it loads very slowly.  Then when it finally loads and i click on a parent node the page starts loading slowly again and then finally shows the sub nodes.  In Internet Explorer the treeview loads fast and works fine...I am only having this problem with firefox...does anyone know why this is happening and how to fix it...thanx

What version of the adapter kit are you using?  We just released beta 3.  If you haven't upgraded, I suggest you do because there are a lot of TreeView fixes in beta 3 compared to 2.

Also, are you experiencing the slowness using FireFox to view the sample TreeView page that comes with the kit, http://www.asp.net/cssadpaters/treeview.aspx?  If that sample is running well for you on all browsers then you might want to start comparing what you are doing versus what is being done in the sample.

I've not seen or heard of this performance problem before.  I'm suspicious that you are running into something cause by something that is unique in your use of CSS, JavaScript, etc.  That's why I want to confirm that you are (or are NOT) seeing the problem with FireFox with the TreeView sample page.  If it is working quickly for you, then you can begin to try to spot what you are doing differently in the page that is slow.

I just recently downloaded the adapter kit...I don't think its even been two weeks yet...im not sure what beta version i downloaded but in the readme.txt file that's in the tutorial at the top it says CSS FRIENDLY ASP.NET 2.0 CONTROL ADAPTERS, Beta 2.0  so I guess that is the version i have.

 Also when i use the sample treeview that is provided, it does load slow in firefox but when it loads it works fine and it doesnt reload every time i select a node

We released beta 3 of the kit earlier this week.  I strongly suggest that you use it, instead.  You can download and learn about it from http://www.asp.net/cssadapters.  There are lots of cool enhancements in beta 3 specifically for the TreeView adapter.  You might find that you like it better, and you may find that it happens to fix performance problems, though I'm not sure offhand why your performance using beta 2 would be poor.  In any case, I think you'll like beta 3 better.

Good luck.
