There is a lot of chatter about the improvements HTML5 is about to unleash on the web development world. How will this new standard affect web dev frameworks like Faces, Struts, or even ASP.NET? How long will it take them to 'catch up' in order to emit such code? Will controls get deprecated?

I have a web page with an UpdatePanel containing two GridViews and related controls. There is a Save button on the page outside the UpdatePanel. One of the event handlers for a control inside the UpdatePanel calls a method DisplaySaveButton, which is supposed to make the Save button visible or not depending on a parameter. Although DisplaySaveButton is called & executed correctly, it does not effect the visibility of the Save button.
If I remove the UpdatePanel from the form, leaving all its content behind, everything works perfectly.
how do I affect the state of a control outside the UpdatePanel?
I have a Gridview that has some controls above you can use to select how much data the Gridview displays - a week's worth, a month's worth, a year's worth etc.
And, as it's a view only grid, I thought 'I'll keep the page size down by doing this:
<asp:GridView EnableViewState="false" etc.
But, if I look at a year's worth of data and look at Page Source - the ViewState is massive. If I look at a week's work, the ViewState is small. A month's worth - a bit bigger and so on.
So, despite setting EnableViewState to false - the ViewState does seem to grow in proportion to the data being displayed in the Grid. I don't need all that data held in ViewState so why is it happening?
I have had this problem for a long time now and have just dealt with it but i am at the point finally that i need a solution or i need to look at other options besides visual studio for web development. it is way too time consuming now to have to worry about changing one thing and then having to search all other pages to be sure they are still fine. So this is what i have: visual studio 2008 pro sp1 asp.net web application targeting .net framework 3.5
a master page with several tables. i have broken out into several tables because it seemed to help the issue. the tables are all stacked on top of each other, no special positioning. the tables seem to be fine for the most part but if i make changes to the table which contains the content placeholder, i will find other pages have formatting incorrect, such as backcolor of text in different areas changed, bulleted lists are overlapping. when navigating to some pages, one of the tables i have at the top that is not related to the table with the content placeholdder, will not show the background picture, and it will show either different font size of the menu that is in the table with the content placeholder, or bold font on other buttons text, such as link button, on the master page.
so they seem to affect each other. changes on the master page affect the other pages and when displaying the other pages, whether in a browser in the IDE, parts of the master page will be affected. this is only on certain pages and they are never consistent. they will stay consistent once changed, but each time i make a change to the master page, the pages which are affected are not consistent. However, it used to be a issue that was always consistent with certain pages i kept in their own folder. i had taken the time once to go through them and make fixes and after that i didn't really have any more issues. but now they are being affected again as well as others.
i had started using link buttons instead of hyperlinks because it seemed to not affect the other pages when formatting them. for instance i would highlight the backcolor of a link with yellow, and other pages text in random places would show with the same yellow backcolor. it does not seem to matter what any of the affected text is in whether in p or div, it doesn't seem to follow a pattern other than sometimes it does seem to favor text that is bold. i think in some ways it has to do with new content pages i add to the site. those seem to be the ones that are usually affected for sure. but there are always others and i never know for sure which ones they will be.

I am developing a site similar to forums. I allow users to Post articles and upload files regarding the articles. I am not storing the Attachments contents in DB instead i store only the path of the attachment file and store the actual file in physical folder in the Project directory. WHat i want to knw is if the size of the physical folder increase will it affect the performance of my application.
View 6 RepliesWe have a webfarm using a SQL Server 2000 database to store our session state.
On the same SQL server are our databases for the rest of the websites. The databases are separate but on the same server.
Recently I found that one of our developers is using the session very inefficiently. He is storing large datatables within the session for users when he could accomplish the same thing through other methods.
Can this inefficient use of the session state (when stored in SQL Server) affect the performance of our main database when they are on the same server?
The answer seems to be yes, to some degree. However, I cannot find any documentation to back me up.

View 8 RepliesI have a need to run an application in classic mode for backwards compatibility with a specific application, and am trying to understand what kind of impact that will have on the performance of an MVC application that is running on the site. If we put a few static file maps (for .js, .css, .png, etc) above the ASP.NET wildcard map to reduce the amount of processing by the ASP.NET handler, will we be approaching the integrated mode in terms of performance?
The thing i'm primarily concerned with is any effect this might have on output caching. I understand that integrated mode might (?) allow for the output cache to handle non ASP.NET content, but that isn't really a concern. We're more interested in ensuring that the MVC application has full use of the output cache. Empirically i've found that the two configurations operate on par when things go well, but if the page references resources that are not available, the integrated mode tends to fail much more quickly than the classic mode (e.g. 500 ms vs 10 seconds), reducing 'hang time' on the page load.
I have a dataset that comprises of multiple tables (about 20) linked together with constraints to reflect the relational database. My question(s):
1) Will having multiple tables affect performance? I'm asking this as there are often times I would not need to get data for all the tables, but only for specific tables.
2) If it does affect performance, would breaking up the tables into their own datasets be the best solution. It seems to me that by doing that, you would lose the ability to apply constraints among tables and tables that might exist in multiple datasets will be subjected to replication.
I would like to have everything in one dataset as I get a view of the related tables and their relationships and also because the Fill method allow me to fill tables, maintaining the hierarchy of the data, but performance is still a key factor.
in other words, what happens when I enable/disable FrontPage Server Extensions 2002? knowing that I have asp.net web apps using .NET framework 1.1 and 2.0

The temp folder size is increased every month as we manually add images.
Except the Temp folder every page is requested from the browser...
We dont use the Temp folder for any other purpose other than archive.
Does this affect the performance of the web application i.e. constant size increase?
how different would it be if we moved the temp to some other location out of the Root?
