we are creating a custom content management and out portal page is bit bulky it is about 60Kb without images.
and during loading the page in some browser we can see some parts of site load faster than the other parts of the site where as we want to indicate (or instruct the web server) to load some of the areas first then load rest of the page.
is there any particular setting in IIS for is there any particular method in classic asp for doing that?
also I have the same question in asp.net.

I'm developing a custom webcontrol from GridView.
I've run into this bizarre situation wherein I get the below error if I set page size other than 5 in the page using this control.
"Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."
This GridView is a hierarchial type. I add a new GridView below each row in the webcontrol overriding OnRowDataBound.
If I set pagesize as 5 the paging works properly.

Yes, it's the infamous viewstate again! Now I am aware that problems can ocurr if you load controls in the wrong order or if the viewstate IDs are incorrect after postbacks etc etc. But my issue is that I am not really creating any controls dynamically - I only have one user control on the page.
More importantly, the issue seems to be occuring with just one user. What could be the problem? Corrupt browser cache?
ok - so I've narrowed it down a bit more. When I select an item from a drop down list control (which is a UserControl) - and then attempt to rebind my grid using the selected value, the error occurs.
The selectedvalue on postback seems to be zero every time (because the control is not in the viewstate somehow?!). The UserControl (containing the dropdownlist) is added at design-time.

I have Temporary table. I want to generate the Update statement by using this temporary table. Then temporary table data length can have more then 5000. So I need to generate the update statement in dynamically and stored in variable. I have tried this logic but dynamically generated update statement length is getting exceed. So my update statement is getting failed. I do not know how to achieve. how to overcome this issue? I have shown the piece of code which I tried
DECLARE @strFieldName varchar(max)
DECLARE @strFieldData varchar(max)
DECLARE @strUpdateSql varchar(max)
DECLARE @strUpdateSql1 varchar(max)

I am using the gleamtech filevistacontrol for a back-end of a website. When i load the page which contains the control i get an error that a language file could not be found.
I get an 404 response when calling the webservice. The application is running on a windows server 2008. On my development machine the application is running without problems. I got the filevista control running in another application but this is running on a windows server 2003 machine.
Things i have tried:1. Verified all that all files are there and that the permissions are set correctly
I added the following line in my web.config in the system.web section.
<webServices>
<protocols>
<add name="HttpPost"/>
</protocols>
</webServices>
I started from scratch with deploying the application. I tried two different versions of the filevistacontrol
My guess is that is has something to do with the asmx that couldn't be loaded but i am out of options..

My app is an ASP.NET 2.0 website. I use UpdatePanel to contain all UserControls. I also use ReportViewer control (local mode) for report function. When user click on "View Report" button, a javascript will be executed to open a new window which contains the ReportViewer control. Everything works well in my pc (Windows XP, IIS 5.1).
However, when I deploy the code to app server (Windows 2k3, IIS 6), I encounter a critical issue. After the report window is opened, whenever I click a button or change value of a DropDownList (UpdatePanel will be reloaded after these actions), an exception "Failed to load viewstate" is thrown.
I've tried to update the Report Viewer Redistributable 2005
(http://www.microsoft.com/downloads/en/details.aspx?FamilyID=e7d661ba-dc95-4eb3-8916-3e31340ddc2c) in the server to SP1 (assembly version: 8.0.50727.817),

I read you can set matching keys in web.config files across a cluster.
But does it have to match across all the seperate apps on the cluster or is it in pairs?
IE... app1 on both clustered servers match or all apps on both servers have the same key?

I wanted to make extensive changes to a project, so I created a copy of the project folder. In the new version, I renamed all of my namespaces and a few classes. Everything compiles and runs, however, I am getting this javascript error. 'ASP.NET Ajax client-side framework failed to load' and my 'Auto complete' text box no longer works. This error does not occur in the original project.
The HTML source between the original and the new project are identical, save for the few lines of code that throw this error. The web.config files are identical.

I got gzip working, but there are issues with IE. (works fine with FF and Chrome) Message: ASP.NET Ajax client-side framework failed to load. (and many other js related errors)
How can I prevent gzip compression on ie browsers ?? Other people who had similar issues enabled compression in IIS and that seems to solve the issue, but I can't do this on my discount machine...
This is what I use:
HttpApplication app = (HttpApplication)sender;
string acceptEncoding = app.Request.Headers["Accept-Encoding"];
Stream prevUncompressedStream = app.Response.Filter;
if (acceptEncoding != null && acceptEncoding.Length != 0)

I've been assigned a task to get a site ready for migration over to a load balanced architecture. It will have 4 active servers and 2 static, where the active ones will contain the main site, with the static ones containing images, text files etc..My question is, what is the best way to deal with the image paths in this situation?e.g. one one server the image will be something like : 'serverONE/images/image.jpg' but this need the ability to change to 'serverTWO/images/image.jpg'
