I get the following when I click on a custom made webpart in the Web Part Gallery: The control with ID 'UpdatePanel1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it. If I use the webpart, ie perform a search, I get a pop-up error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The Status code returned from the server was: 500.
This webpart takes a search string from a textbox, passes it to BL/DAL and returns a data from DB. I've integrated an UpdatePanel for partial postbacks - used this blog as guide but it is not working.
I've added the scriptManager to the default.master page using MSSP Designer as the blog suggests but curiously, the script manager causes an error (red underline) In Internet Explorer 6.0 the tag <asp:ScriptManager> is not permitted.
I'm not totally sure what's up with that but here's an alternative. Dont use MS Ajax - EVER. jQuery is simpler, faster, better, stronger, sexier!
This is how I normally do this stuff:
add jQuery to your master page head
create a user control that implements your web part ui. This should use Page.ScriptManager.RegistryScriptInclude or .RegistryScriptBlock to insert script for the control. Eg, methods to do your callback using jQuery.Ajax.
create a web part wrapper for the user control
create an aspx in _layouts that acts as the 'service' for your callback. The page load can use the parameters passed from the ajax call to return some json or text
Instead of #4 you could create a web service but this is a lot harder with SharePoint - an apx will work well enough.

I made a simple workflow in Orchard 1.9.1 to notify when a dynamic forms is submitted.
I didn't set any prpoperty/data on the Start Activity so that it can capture all Dynamic Forms submission. However there seems an issue and the workflow is NOT being invoked.
I followed steps from here: http://docs.orchardproject.net/Documentation/Workflows
But this notify activity or may be even the start activity doesn't seem to be invoked/working . What More settings are required to get this workflow in action ?
Also, I have set the redirect URL in "Forms" element properties but the form isn't redirecting. What can be the issue here as well ?
I have not seen this problem with a workflow before. I assume there's nothing in the logs?
My first guess would be that it's your form that is not submitting properly, try to remove that redirect, also make sure there's isn't some validation error blocking it, if you placed recaptcha element remove it and try again.
Second guess which is not very likely is that you have somehow managed to hide notification zone, either with CSS or in layout view #Zone(Model.Messages)
I have an unusual scenario in which only one page of our SP 2007 site is throwing this error "You are not authorized to view this page".
Here are some details:
SP 2007 Enterprise
The page in question uses SmartPart to display custom usercontrol.
We have 50+ pages that also use custom user controls in SmartPart, and none of them generate this error.
The page in question has several functions, and it initially loads just fine. First time it loads, user selects a customer from a dropdown, then enters a search query and clicks the search button. That all works, and the page then returns some search results. That works as well. The the user can click on a Modify link for each item. It's clicking on this Modify link that generates the page error. All of these things are done one this one page, it just refreshes accordingly. The Modify link is just a standard asp:commandline field that causes the page to load the line item in editable mode.
Here's the other strange thing. If I login as the SP Administrator account, and go to this page, it all works properly, no errors...and, then all other users can go in and use the page properly, without errors as well. It's as if whatever the security issue is, is being resolved temporarily as a result of the Admin using the page first. But after a code publish, or IISRESET, etc, the page goes back to not working for any general users.
Any ideas on what I should look for in trying to resolve this issue? I can also provide code if anyone thinks that may be relevant.
Thanks!
use SPSecurity.RunWithElevatedPrivileges for running your code with anonymous access user:
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite site = new SPSite(web.Site.ID))
{
// implementation details omitted
}
});
I am new to .Net trying to understand about different controls here. I know, custom control, an extension of existing control. User control, a complicated control constructed in .ascx file and can be used anywhere in the application. I couldn't the concept of createchildcontrol() and need of it.
thanks !
It plays the role in the lifecycle of a page request to ensure all controls generated dynamically/via code are in place for binding postback values and rendering out to the page. Also note from the MSDN page:
When you develop a composite or templated server control, you must
override this method.
You can check this page for the full list of events, in order, on an ASPX request.
How can I set a custom user agent for a webbrowser control? The control is loading a page where I need to spoof it. I am using c sharp.
This has been asked many times on here. I suggest searching for a solution next time before posting a new question, but you can easily do this by using the WebBrowser control's Navigate() method. Just note that this will only work when you use this method, after you navigate to another page, it will "reset".
webBrowser1.Navigate("http://yoursite.com", "_self", null, "User-Agent: Custom User Agent string");
Also, other header information can be included in the header parameter as well. More information can be found here.
Microsoft's official way to customize the User Agent is to implement the IOleControl::OnAmbientPropertyChange event to respond to DISPID_AMBIENT_USERAGENT requests (but does not affect Navigate() or a page's DOM), or use UrlMkSetSessionOption(URLMON_OPTION_USERAGENT).
Anybody used the "ItemAdding" method successfully in an Event Receiver in Sharepoint for validation?
I think it just can't work properly for validation purposes because it seems that :
You can't access the data you just
entered in a form
If you add an error message,
instead of displaying the form
back with your error, Sharepoint
display the big ugly error page.
Here's what I found so far on the web for the ItemAdding method :
http://www.sharepoint-tips.com/2006/09/synchronous-add-list-event-itemadding.html
http://www.moss2007.be/blogs/vandest/archive/2007/07/20/wss-3-0-event-handler-pre-event-cancelling-issues.aspx
http://www.synergyonline.com/blog/blog-moss/Lists/Posts/Post.aspx?ID=25
Anyway, if somebody successfully used that method, please tell me how because I think that it's just broken/missing something!
Thanks!
You can't use ItemAdding to perform that kind of "friendly" validation checking. If you set e.Cancel = true and set e.ErrorMessage, sharepoint will redirect you to the standard error page and display your message. You can't make it redirect back to your form page.
Rather than trying to hack the built in pages, you should use an infopath or aspx form bound to a content type. Infopath has built-in validation controls and with aspx forms you build yourself you can treat it like any web app and choose your own validation.
No easy way out here I'm afraid.

You can access data that was just added in the form. Look at properties.AfterProperties in the adding/updating event receivers.
An example would be properties.AfterProperties["Title"].
I agree that error handling is a little hard, but I recommend that you do validation in your event receivers in addition to having your UI do validation. If it is not a custom page, then you can add JavaScript to existing pages using a Content Editor Web Part to do the validation.
