[RESOLVED] how to set the Textbox autocomplete source to specific column in my datatable

[jmcilhinney]

thankx jmc for replying. i am using 3.5 as i am using vb.net 2008

That doesn't necessarily follow as VB 2008 can target .NET 2.0, 3.0 or 3.5.

You'll need to have imported the System.Linq namespace.
