I found something else.
Grid.Options.Grouping.MergeSummary := false and things worked. It was true on the object inspector.
I have removed the loop to set the Floats. I dont understand, but worked.
I am not having access to the livebinding property that is displayed on object inspector for the Grid.
I was thinking in copy the column name defined there, to the columns.items[x].name on the grid.
so that I could get the columns by using columns.ColumnByName
How can I get that? I know i could use the row[0] for that, but the title is different than the member name from the livebinding, that represents directly the dataset field name. Which is better to be used and remembered.
