[Sagar Baheti]

Hi,

Thanks,
Sagar

I'm facing the same problem and can't find an answer. I've looked through the help documentation and found how to do it with the XMLDataSource using Xpath and the sitemap datasource, but I'm binding to and ObjectDataSource and need to hide the root node.

This table contains a list of categories... For example:   Pants, Tops, Hats, Socks, Underwear, Accessories
From the home page they would see the main treeview showing all the above items.   When the person clicks on "Tops" for example, they would then be taken to a sub page.  On that page I only want to display the tree with items under the "Tops" classification.


Clothes (tops)
--- Long Sleeve
--- Short Sleeve
--- Sweaters
---------  Wool
---------  cashmere
---------  Cotton
-- Tank Tops

-----------------------------------------
I want it to just say:  (Since they are on the Clothes-Tops page)
-----------------------------------------

Long Sleeve
Short Sleeve
Sweaters
----  Wool
----  cashmere
----  Cotton
Tank Tops

-----------------------------------------
Idealy I'd like to have a property of [DisplayRootNodes = false;] but I'm guessing thats not going to happen... So at this point I'm just looking for a solution.


Can anyone help?

Hello Jeremy Mann,

RadTreeView does not support this functionality.

However, you can use the standard SiteMapDataSource control to serve you as a data source for the TreeView. You can control the starting Node which the data source will return, so you can achieve your goal relatively easily.

Please read more about the control and its usage here.

Hello,

does anything related to this issue/request has changed in Q1 2010? In my opinon there should be this kind of possibility. Root node is only taking space by indenting whole treeview.

Thanks

Hi GrZeCh,

Currently we do not have plans for adding such a feature to RadTreeView.

Please use a SiteMapDataSource as previously suggested or modify your current data query to return the children of the root Node as root Nodes themselves, so that they appear on the first level of the TreeView.

Kind regards,
Simon
