It could be any cell.

As an example: The grid represents a table that has the following:

unitcost, qty ,sell,extendedsell,description

Each row has a parent and child row. The user can configure the grid so that the columns can either be part of the parent or child row, such as:

parent: unitcost,qty,sell

child: extendedsell,description

When they change of the value of qty, I have code in the afterupdate event that updates the other sells such as extended sell. I don't know at design time where extended sell is (in the parent or the child) so I use code like shown above to see if the extended sell is in the parent or the child (taking into consideration that qty could be in either parent or the child). In the example below, dg is a class that has a decimal property for parsing.

decimal)e.Cell.Row.Cells["mfgrlist"].Value;

else

(e.Cell.Row.Band.Index == 0)

dg.Parse = (

decimal)e.Cell.Row.ChildBands[0].Rows[0].Cells["mfgrlist"].Value;

else

decimal)e.Cell.Row.ParentRow.Cells["mfgrlist"].Value;

So your tree control has a getnodebykey method, I was wondering if somewhere in the grid control there is a getcellbykey that can search both parent or child rows.

No, there's nothing like that in the grid.

But since you are presumably setting up the data structure in code, you know at some point where each column is and in which band is exists. So you can track that information when the data structure is generated.

You could also use the band.Columns.Exists method to determine if the column exists in the band.
