I'm using some small atlas on the page (just update panel and script manager) and I keep running into this javascript error every time I try to submit. I was sure it was a validation thing, so i pulled all the validation tags off the page, but it's still firing. Any ideas? If it's not clear, my form is not named "theForm" and i have no idea where that comes from. In FF, I was able to see the code, and here's what's happening Error: theForm is not definedSource File: http://localhost:13656/WebResource.axd?d=s3dJX5e_e431rKXwpmcp9w2Line: 19function WebForm_PostBackOptions(eventTarget, eventArgument, validation, validationGroup, actionUrl, trackFocus, clientSubmit) { this.eventTarget = eventTarget; this.eventArgument = eventArgument; this.validation = validation; this.validationGroup = validationGroup; this.actionUrl = actionUrl; this.trackFocus = trackFocus; this.clientSubmit = clientSubmit; } function WebForm_DoPostBackWithOptions(options) { var validationResult = true; if (options.validation) { if (typeof(Page_ClientValidate) == 'function') { validationResult = Page_ClientValidate(options.validationGroup); } } if (validationResult) { if ((typeof(options.actionUrl) != "undefined") && (options.actionUrl != null) && (options.actionUrl.length > 0)) { theForm.action =

Hi, I'm developing using the new ASP.NET 4 and I ran into the following issue. When I put a Menu control into the web form, the menu causes the following code to generate just before the closing </form> tag:<script type='text/javascript'>new Sys.WebForms.Menu({ element: 'NavigationMenu', disappearAfter: 500, orientation: 'horizontal', tabIndex: 0, disabled: false });  As long as I don't use URL Routing, the page compiles and loads properly. But when I try to use URL Routing on the website, VS starts to throw "Sys is undefined" exception. However, this does not happen always. Most frequently it happens when I change somenting positioning-related in the CSS file, but sometimes the exceptions seems just arbitrary. I'm not sure which parts of code could help, if any. I would appreciate any help. Thx

I'm using SharePoint Designer to add a custom view to the default page of a site. I want to filter the data on some query string values - but only if the query string values actually exist. I haven't been able to figure out how to do that, either in the gui or by hacking around with the actual where clause. The where clause is below. Anyone have any ideas?

 <Where>

I have a site which I've been implementing MS Ajax a little at a time for the past year.  I have been trying to clean it up and implement some of the best practices which I know I should have done in the first place.  So last night, I went to the web.config file on my production server and changed the <compilation debug="true" /> to say debug="false".  This supposedly will allow better script & resource caching, but since the web application was built in debug mode, I'll still get the detailed exception stack traces which are so helpful in finding errors.

After changing the compilation debug="false", I am now getting the following error from the pages of my site which have implemented MS Ajax:

'Sys$WebForms$PageRequestManager$_getScrollPosition' is undefined

 

Changing that compilation debug switch was the only thing that has changed since yesterday when I was not getting these errors.  Everything else seems to work correctly, and I am catching this error and reporting it correctly without displaying the error to the user.  However, my inbox is getting flooded with these errors which seem completely unnecessary.

Anybody seen this before?  Obviously, I can flip that switch back to
