Question

The Situation

In Sharepoint 2010 I can click on an item in a list:

And then the Read/Edit view becomes visible in that page:

My Goal

I have a WebPart on another Page where I show some items coming from this and several other lists and I want to add a read or edit link to each of them.

How can I do that?

I’m searching for a function like EditListItem('ItemId', 'ListId', ...) which will open the edit div window.

What have I tried

The a tag generated by Sharepoint on “Test Item” above is like this:

<a onfocus="OnLink(this)" 
   href="http://{mysharepointsite}/_layouts/listform.aspx
         ?PageType=4
         &amp;ListId={D0FDB54F-1DDF-4C5E-865B-ABDE55C1125}
         &amp;ID=1
         &amp;ContentTypeID=0x010800ED5176D13CCEFC4AA8D62A79985DE892"
   onclick="EditLink2(this,49);return false;" target="_self">Test Item</a>

So I digged a bit into the Sharepoint JS files and found EditLink2 calling _EditLink2 which calls ShowPopup from the context (the 49) is the context no and seems to be dynamic.

I tried to fake the context but there are billions of variables and I think I can’t get that to work stable.

On that page where you need to open dialog just write simple JS function for showing modal dialog, for example:

function openMyItemDialog( itemId ) {
    var options = {
        url: "http://{mysharepointsite}/_layouts/listform.aspx?PageType=4&ListId={D0FDB54F-1DDF-4C5E-865B-ABDE55C1125}&ID=" + itemId + "&ContentTypeID=0x010800ED5176D13CCEFC4AA8D62A79985DE892&IsDlg=1",
        width: 500,
        height: 500,
        title: "Item view/edit"
    };
    SP.UI.ModalDialog.showModalDialog( options );
}

Note the &IsDlg=1 param at url

And then modify href link where you display your items.

For example:

<a href="#" onclick="openMyItemDialog(35)">Test item</a>

Replace 35 to ID of your item
