How to open New List Item Form in modal dialog in a SharePoint 2010 page from different site collection

Question

I need to open a new list item form on hyperlink, or button click, in a Sharepoint 2010 page. The page and the list are in different site collections. I must do this from the Sharepoint Designer, or directly editing the page in a browser, Visual studio project is not possible/allowed...

Can this be done, and how?

Solution

P.S. Most safe way to address New form is to use ListForm.aspx page, as follows:

 /_layouts/listform.aspx?PageType=8&ListId={PUT-LIST-GUID-HERE}

(PageType value goes from PAGETYPE enumeration)

i think you should be work when use PAGE_NEWFORMDIALOG : New form for a file dialog box.Value=9 as describe on msdn. if New form is not open on model pop up than

Try this :

HyperLink

 <a href='javascript:;' onclick='Opendialog()'>New Item</a>

Opendialog is Javascript Function

   function Opendialog() {
       var options = SP.UI.$create_DialogOptions();
       options.resizable = 1;
       options.scroll = 1;
       options.url = SiteURLWhichExistList + "/_layouts/listform.aspx?PageType=8&ListId={PUT-LIST-GUID-HERE}";
       options.dialogReturnValueCallback = Function.createDelegate(null, CloseCallback);
       SP.UI.ModalDialog.showModalDialog(options);
   } 

Note : SiteURLWhichExistList pass your site collection url in where your list exist.

Hope it helps!!

I've done something very similar to this, but I'm still having one more problem. As a form (the one I'm showing in a popup) is on another site collection, after I submit data, it does not close automatically. Instead I'm getting javascript error "Access is denied". Do you have any idea how to get around this?

In most cases, you can use _spPageContextInfo.webServerRelativeUrl for that "SiteURLWhichExistList" replace-me-with-your-value var in your example. Btw, your example worked fabulous for me, thanks. I +1'd it.
