GroupBy and retrieving Rows

Russell posted over 16 years ago

Hi,

I ran into a problem where I have a grid which is populated with a BindingList<> of simple objects. I would have a user then click a button and I would iterate over the Grid.Rows property retrieving cell information, all was good until I enabled GroupBy.

I then found that the Grid.Rows collection now only had one row in it with IsGroupBy set to true and a hierarchical tree of data now available via its ChildBands property - dependant on howmany times the user decided to GroupBy.

Is there a way where I can still allow users to GroupBy but still access the flat hierarchical data as I was before? Instead of what I am guessing is going to be a recursive tree walk? Note I used an unbound column in my data so accesing the datasource directly I believe won't help.

Any ideas - as I am sure there has to be an easier way and that I am over complicating things?

If it helps clarify I have a list of people and an unbound boolean column to select those people. I then wish to iterate over the rows and pull data out if the unbound column is checked or not. This I can do, the only snag is there are other columns available for the person for which the user can group by - but I still wish to iterate over the full list of people and using the unbound column value retrieve their details.

There are methods on the rows collection to help you do this.

            UltraGridRow[ rows = this.ultraGrid1.Rows.GetFilteredInNonGroupByRows();
            foreach (UltraGridRow row in rows)
            {
                // Do Something
            }

I'm not sure what you are trying to do here... copy the entire grid into a data table?

You are correct, an UltraGridRow is not a DataRow. So you would have to copy the data individually, you can't just convert a grid row to a data row automatically.
