I have this WebHierarchicalDataGrid below the user needs to be able to edit data at both the parent and child level. I have the parent level working. At the child level the data that needs to be edited is a dropdown list. I have added the DropDownProvider and set the EditorID. when clicking on the FIRST row in the child I can edit using the dropdown. The remaining rows in the child grid do not present the dropdown list. My parent grid, child grid and dropdown list are being populated by datasets, no issues with data load. Please let me know what I need to do to get all the rows in the child to present the dropdown list for editing.

Here is the code for the dropdown list:

Dim DDPRT As DropDownProvider = CType(WHDG.EditorProviders("WHDG_DropDownProvider1"), DropDownProvider)
DDPRT.EditorControl.DataSource = dsRT
DDPRT.EditorControl.TextField = "RestrictType"
DDPRT.EditorControl.ValueField = "RestrictType"
