I am using an ultrawebgrid in which I have two ultragridbands defined.  I want to change a value in the child band however, when I use updateRowBatch, it does not realize a change has been made to the child band.  It only tries to look for changes in the parent band.  If I test the value of e.Row.Band.Key it is always the key of the parent band, but it never tests for the key of the child band.  I don't have this issue with InitializeRow.  That is able to initialize all rows in the grid whether they are part of the parent band or child band.  This is what I am using:

Protected Sub ReceiptGrid_UpdateRowBatch(ByVal sender As Object, ByVal e As Infragistics.WebUI.UltraWebGrid.RowEventArgs) Handles ReceiptGrid.UpdateRowBatch

Is it possible to update cells in a child band via updateRowBatch?
