Hi All,

I have a tree which is using a DataSet as its datasource.  This dataset consists of a parent and a child table, the parent table contains one row and the child table can contain any number of rows.

Everything works fine however when the child table grows to about 100 or so entries the ExpandAll() method just hangs.  Eventually it returns and the tree is successfully fully expanded however when I then manually collapse and expand some of the lower level nodes the tree still hangs and takes quite a while for the collapse or expand to occur.

Has anyone else seen any issues like this?  Any ideas on what may be happening?

Thanks,

Denis
