How to add DataSource to a TreeView programmatically

[anders.rask]

Hi,

im creating a custom control (custom SPField in WSS v3) that renders a
TreeView control.

This works fine if i add TreeNodes manually to the nodes collection,
but what i really want to do is add a SiteMap provider as datasource
for the control.

I am doing this programmatically in CreateChildControls but so far
without much luck:

I get no errors, but the TreeView renders without any data in it.


Code (inside CreateChildControls of component):
_siteMapDataSource = new SiteMapDataSource(); //defined
outside method
_siteMapDataSource.SiteMapProvider =
"SPContentMapProvider";//taken from web.config
_siteMapDataSource.StartFromCurrentNode = true;
_siteMapDataSource.ShowStartingNode = false;

_siteMapDataSource.DataBind();//not sure this is
necesarry..


_spTreeView.DataSourceID = _siteMapDataSource.ID;
_spTreeView.DataBind();

I tried with all the sitemap providers in web.config but none of them
seems to work...

any help or hint appreciated!

thx

This appears to be all that is required.

SiteMapDataSource smds = new SiteMapDataSource();
smds.Provider = SiteMap.Providers["Default"]; // Name from
web.config
TreeView1.DataSource = smds;
TreeView1.DataBind();

ID is only used when you are using a datasource control.
