Hello,
We've noticed a change in the Hierarchical WebGrid behavior when we uprgraded to 2009R1 SP1. In the past if a parent table contained an empty value in the key column, the child table would still be loaded, and the row with the empty key value would simply have no children. Now I'm seeing that none of the parent rows are populated with any cildren if one of the parent key values is blank. Is this something that has a workaround?\
Thank you,
Dasha.
Using the latest build of WebGrid and WebUI Framework we could not replicate the issue in our environment. Attached is the sample we use to replicate the scenario in our environment. On of the parent row is set to have an empty string as the key.
