How can I sort the DGV by a column other than the primary key?

I tried

DGV.Sort(DGV.Columns(0), System.ComponentModel.ListSortDirection.Ascending)

but got the error “DataGridView control cannot be sorted if it is bound to an IBindingList that does not support sorting.”

thanks

The program data are inserted, but when you exit debug mode, the data is not in the database.

Thanks.

fantastic example. It gave me the kick for building a solution.

Having the same error as Matthew two posts above on random installs (XP SP2 and SP3) never had this error on Vista or W7, yet.

The error appears when opening a database.

any suggestion or provide help!

Thanks.

I am trying to create an sdf file with c# webservices on a windows 2003 server box but get this error and can’t find any other help.

Unspecified error [ sqlcese30.sys.dll ]
- this is the error when the program does “engine.CreateDatabase();”
My code runs fine on my workstation. I’ve checked folder permissions, I’ve copied sqlcese30.sys.dll into the bin folder, I’ve installed the SQL Server 2005 Compact Edition Developers SDK on the server…

Can you help me solve this error, please?

Cheers

Matthew
