I have VS 2005. I have created a  view in my database combining data from 2 different tables. I can update & delete from Ent. Mgr. When I create a datagrid view or a "details"  object from the datasource in my ADO.Net app., I get the data from the combined tables entered into the form, but the "save" button is not enabled. I enable the the button but I still cannot update the data entered or deleted in the form. How do I manipulate the data in my dataview thru my form?

Thanks

Or another way of putting it, I want to add an unbound column to a datagrid. That datagrid is already bound to a data table. Column1 in the datagridview is EmployeeID and shows the ID number. I would like Column1 to show the Name associated with the EmployeeID from the related Employee table, instead of the ID number.

1) If you are using Inner Joins, or any other complex queries like that, you will not be able to update.  

2) Are you using Table adapters?

I tried to create a view using joins and found that the table adapter wouldn't allow me to update. When I tried to code it, the intelisence would not bring up the update command. When I go to Enterprise manager and create a view there, I can update it. I guess I'll try to see if I can do it through a SQL command.

The table adapter needs enough key information to update the tables.  Maybe it is because you haven't included enough fields from the secondary table to do an update.

I won't be able to get to my machine until tomorrow. But I'll have to see if I included or not the PK field. I didn't really think about not having enough of the fields, but it does sound logical.
