I have a datagridview bound to a datasource that is used as the master in a master detail arrangement.
It has lastname and firstname fields, I need a single field with the names concatanated.
I don't see how to plug in a formatting function and assign it to a column
In the java application that I am porting, similar issues were handled by reading the dataset into a class and calling a formating function when the field is displayed. I don't see how to do this in the datagridview/datadapter world of C#
Thanks

If you are looking to format bound data displayed in a databound textbox you need to use the Format event of the data binding.

I would bind my textbox to a bindingsource and in the format event you can use the bindingSource's Current property to gain access to the other columns in that row.

Maybe this article can help:

Thanks, but that does not really address the issue. I have a form with a few dozen textboxes bound to database fields via a dataAdapter. Most of the boxes are bound to a single field but some of them need to be formated with data from separate fields. ie. 268 in AREA_CODE and 245-5890 in PHONE would be displayed as (268) 245-5890 on the form. I see no way to do this in designer.

That gets me almost there. I have one textbox that displays data from five fields. I can handle the concatenation etc in the format event handler but how do I get the data. I only see how to bind one field to the control.
Thanks,
