Ribbon buttons are greyed out when using a custom form template

Question

So I've created a custom form template based on the default ListForm (haven't changed much there, basically just the title), I've set up a custom content type and I've added that to a Tasks list. When I try to create a new task, I see this:

Does anyone knows why the ribbon could be disabled in this case?

Answer 1

I had a similar problem to above - the ribbon options were grey (gray) when I showed a list item using a Rendering Template. The ribbon also showed a lot more options than you usually see when viewing an item.

My soltuion was simple though: I'd forgotton to include this line in the template:

<SharePoint:FormToolBar runat="server"/>

Once in the correct, active ribbon appeared.

Hope this saves someone some time ...

What do you mean "haven't changed much there, basically just the title"?

I tried to reproduce your issue, but my form for Tasks list doesn't look like yours:

Here what I have done:

1. Created new "Team Site" site collection
2. Opened Tasks list
3. Opened SharePoint Designer, created new form for the list, and marked it as the default
4. Saved all the changes

So, you should probably recreate your form template, or provide more information about your issue (especially about list and form customizations).

Solved now. I was overwriting the default window.onload handler function for the iframe and thus preventing the ribbon from being initialized. I've switched to using jQuery to attach to the load event, and all works now.
