Any updates on this? I too am wanting to know how to include other inputs. I have a similar situation. I have two grids – a Master grid that creates a sub grid, and they do not share data sets or column values – both are populated from a webservice and the subgrid gets its values from a key off the master. However, I am wanting the master edit feature, to include the sub grid columns / fields. I'm thinking just writing a custom form dialog is the way to go on this?
