Hi Ivan,

You may consider adding a GridButtonColumn to your master table with CommandName="InitInsert" and Text="Insert". This column will be cloned for the nested levels in the self-referencing hierarchy and thus you will have the option to trigger init insert command from the button rendered for each row and display the insertion form.

Thanks Stephen, but isn't there anyway to add the button "Add New Record" on the above of every row till (n-1) in the self referencing, in other words when i select the "MaximumDepth= 3" the "Add New Record' button should appear above the rows till depth 2, so i can add child rows till i reach the max depth. thanks

Hi Ivan,

If you set CommandItemDisplay to a value different than None (default), the [Add new record] button will be displayed for each level of the self-referencing hierarchy to insert new items (taking into account the maximum depth you set to avoid adding more nested levels).

I have the CommandItemDisplay set on Top but in only shows the "Add New Record" on the rows with child nodes only, but when i add a new row for example a row with parentID = 0 it will not show "Add New Record" above it.
