I monitor headers and post vars using Tamper Data so I'm pretty sure I haven't missed anything. My approach is to micmic the post back when the user click on one of the links and parse the response. But the response I'm getting is a page redirect to "Unable to validate data".

I'm trying to validate that a GridView logated in one of the steps of the Wizard Control is populated by the user before the Next button is clicked. What I mean is that I need to block Next (or Prev) button until the user populates a gridview, once the gridview has at least one element then enable the (Next/Prev) buttons. How can I enable/disable Next/Prev buttons within a specific step?.

When ever user tries to open an application other than mozilla(fire fox) or IE browser , we need to alert the user telling him please open the application in IE or Firebox browser. And the browser which he has opened the application should stop and we should not close the browser in which he has opened
Ex : like other browser ( google crome, opera )
So first I need to check which browser are they running the application based on that I need to send an alert message.

View 2 RepliesI think the popup message is a poor idea because OnClientUploadError has already provided developers a good option to handle the error easily in whichever way they prefer. The worst is that if a user clicks OK, he will see a window that should be seen only by software developers. Is there any trick to stop the error alert?

If I upload a file that is larger than the configs max request length I get a "Server Response Error: Unknown Server Error" alert popup. It asks if I want to see the response page and if I click "OK" an application error window pops up saying "Maximum request length exceeded." I found this already. [URL] I was unsuccessful at getting that to work.
I also found another SO question (I can't seem to find it now) that was similar. The difference was that the OP had asked how to redirect to an error page. I don't want to do that. The answer was to use a custom error redirect that gets setup in the web.config.
I simply want to absorb the error and do nothing, I'm using the OnClientUploadError event to handle the error via js. Basically, I just don't want this stupid popup message.
One odd thing is that I don't see the error when running the app locally, but I do see the error when I've got the app deployed out to our server. Note I should have mentioned that I know about the config value to set the max request length. Setting it to be very large won't work for this instance. Update So, I'm wondering if this could be something with the IIS settings of our server. It's odd that it doesn't happen locally. what I should be looking for? Most of what I find on the net suggests modifying the machine.config. However, as I said before, I don't simply want to up the allowed size. I am handling the error fine via js, I don't want this alert to show up under any circumstances. Update Well, it sounds like the IIS default limit is 30MB.
I am trying to display an error to the user of a web page using a javascript alert popup, I currently have the following code to clean the error string:
errorMessage.Replace("'", "'")
But this is not sufficient as some illegal characters are not being removed, is there a static method somewhere in the framework that will format my string for clean insertion into html?Update: my initial question was slightly ambiguous. the string needs to be valid as in alert('this is some 'illegal text' that will not popup');I will try Server.HtmlEncode, hopefully it will do the trick.
I made one application which consumes WCF service and also using nettcp protocal. As we know, WCF application requires .Net3.0 and .Net 3.5 framework. but we have some dealer machine which are having window server 2000 OS now i am not able to install .net 3.5 framework on dealer machine . So we are not able to upgrade old application with new application which are totally based on WCF framework .

I also posted my question on another web site, one suggestion I got is move my codes to codebehind

But this is ObjectDataSources, my understanding is everything have to stay in Class file.
