I have a webtree bound to a webhierarchicalDataSource. This works well for the most part. In this case it's three levels deep. I want to use the built in AJAX functionality of the webtree as there can be a lot of data and the tree bulks out the page's HTML considerably. I have looked at the different LoadOnDemand options and experimented with them and cannot get anything to work along with the webhierarchicalDataSource.
The ideal would be AutomaticSmartCallbacks but when I enable that and click a top level node it simply renders all the top level nodes again under that node. I cannot find anywhere in the documentation information regarding the webhierarchicalDataSource and it's use as a datasource control for other controls using AJAX.
Has anyone else successfully set this up? Any help from Infragistics support?
I have exact same problem. Is there any news about it ?
Regards,
Hello,
I have just spoken to the guys from our development team working on that. In the original version of WHDS this was not on the feature list, but now we acknowledge that this has big potential (automatic load on demand for Tree and Grid when bound to WHDS).
So we can call it a bug or a new feature, it does not really matter, point is the we are currently working on it as we speak and will do our best to have to for our next release (still, I cannot commit to a specific timeframe yet, will let you know if I have further details).
Thanks for the feedback and keep it coming.
