I have involved in developing my first Ajax .Net project and after nearly completing the project we have been testing performance of our application. We have found that the Ajax RoundedCornersExtender has a serious effect on the performance of our application and we improved query results from 4-5 seconds to less than a second by taking it out.
Thanks to firebug we isolated this. I really wish the toolkit controls where thoroughly tested before release.
Anyway, just thought I would share.

I have a master page that contains a simple table. There is probably a 10 pixel space between both the top and left sides of the screen. How do I remove this spacing?
I have tried div and table padding spacing? Any other suggestions?

Found it, I needed to set the style on the body tag. Thought about that about 5 seconds after posting.

Hi, I am making an ASP.NET site with a menu on the side. The menu items are loaded from a database, and the items themselves are hyperlinks(at the moment) created dynamically for each item it finds in the database.
But how do I make the links work? I could just set the URL of it but I am just redirecting to the same page. When that page loads I want it to be able to tell what they just clicked(or if they just came to the site) and generate the content from there.
So I though maybe I could use sessions and then when the page loads it just checks the session with a couply if statements. Will this work? And if so, how do I do it? I have tried many different ways, but no matter what I try I cannot find a way to make a hyperlink do anything onclick besides going to its url.
Please help me, or if you have a better idea(which im sure you will, im new to this) them please share. Much appreciated.
Regards
Matt

You can call javascript from an anchor tag ( a hyperlink )

Look into DataBinding if I understand you correctly, it is very easy to use a repeater control and use data binding to fill in all the data.

You don't need to create a class to do what is already available. EnableViewState = true

hi!
enableviewstate is by default made true for treeview control. may be i have misunderstood what you are trying to say. could you please explain me in detail?
originally the page loads as "tree.aspx". each node has its id and value(which is an integer) all i am trying to do is display a datagrid on the left based on the node they select. lets say if they select sub node of id 5. I am tryign to maintain that expanded subnode plus redirect as
tree.aspx?id=5 (based on which the grid will be filtered. please note the treeview is in left.ascx and grid is in tree.aspx.
please help
thanks in advance

You have the treeview in a user control that is placed on the same page as the grid? Is this correct?
If so, why pass the id via query string? Handle the selectionchanged event on the page.

nope. treeview is in user control and grid is in a webform. how can i pass value from user control(ascx) to webform(aspx)
