can you tell me if it's possible to have the radtreeview on the left and when you click a node id, a grid in the right (same page) is populated with data - the treeview control that ships with asp.net does not seem to have any click events - other than hitting a navigateurl which means we have to pop open a new page for each node click - please advise - thanks.

Hello Jeff,
You can use the NodeClick event as demonstrated in this online example.

my first 2 rows have nulls for the parentid
Exception Details: System.ArgumentException: This constraint cannot be enabled as not all values have corresponding parent values.

Hello Jeff,
This error occurs when some record does not have parent record. Please check if this is not the case. Also root level items should have their ParentID value set to null.

all records have a parent value, except the top 2 which will be the parent nodes - that look right?

i was able to finally get it - the two columns were of diff data types one and int identity and the other a varchar that was setting the parent's to '0' they were part of a temp table and that mattered. - thanks for all the replies.
