Tree doesn't populate on demand - can't find why
Link Posted: 19-Apr-2007 05:36
Hello,
it looks like I need your support, again. I've got two issues, both may be related. I've got the tree in a webpart for Sharepoint.
I test my tree with a specific test-page. It is nothing special, just one tree and the data to load is selected by using a listbox. All trees/data work fine.

Another page holds one tree, it has exactly the same source code in all tree-related issues, the tree loads (from one of the data sources available above, but fixed to this source) fine, but it doesn't try to populate on demand.  When clicking the plus (=PopulateOnDemand is true), no 'Loading' appears, the checkboxes don't react - nothing.

[Edit: removed, solved with the latest version of the tree. The other issue remains...]

The thing is - I can't see any difference anywhere, do you have an idea why the tree loads with exactly the same data on the test page, but not in the configuration described above?
BR,
rawaho

P.S.: Not to mention the bunch of other stuff, where the trees work fine, so the picture may look more badly than it actually is...

Do you have  in this page?

Or do you get any javascript errors when trying to expand/collapse nodes?

In the webpart code no, in the aspx: The ContentPlaceHolder and the WebPartZone are both runat=\"server\".
No Javascript-Errors.

Do you have  and  in the aspx page?

I am asking you because it seems that javascript runtime is not loading at all.

It depends on form runat=server as well as head runat=server.

Hi Evgeny,
sorry, I had to dig down into the masterpage.
Both, form and head have runat=\"server\". All pages use the same masterpage, the working as well as the nonworking, though.

Could you send me (flytreeview.asp -at - 9rays.net) an HTML output generated by your page (clear private data from it of course)?

Or the other way is step-by-step changing of your configuration to the working one, so that you can detect the exact reason (step) when treeview starts operating as it should.
