Me.gridDataBoundGrid1.ExpandAll() giving error?

[Nouman Zaheer]

Hi
I am getting following error when i used the above statment
"Relation is not parented to table to which this DataView points"
I am using two tables,master & detail in a DataSet what i wants is to
1) set the grid properties when the form is loaded so not everytime i have to set properties
2) just refresh the grid pulling out records from database whenever a new record is added
i have used the following code
a) its not giving me any error at form load
b) but when i again call this code when a new records is added and i am pulling again the records from database its giving me the above error
any one can help me out
Thanks

To reset an hierarchical grid, you need to do 2 things.

Me.GridDataBoundGrid1.DataSource = Nothing
Me.GridDataBoundGrid1.Binder.ResetHierarchyLevels()

To use ResetHierarchyLevels, you must have version 1.6.1 as it was not in 1.5.2. The current eval download is 1.6.1. Here is a sample.

I am facing the same problem. Have you manage to solve it. If yes, can you email me the solution? Thanks
