Hi Eric,
Thank you for posting your query to us.
1,Regarding the Column header
................
I am afraid that I was not able to reproduce the issue.I have created a simple sample to test this issue and is working fine.
Here is the code snippet:
Me.TextBox1.Text = Me.GridControl1.Text & "!" & Me.GridControl1(0, Me.GridControl1.CurrentCell.ColIndex).CellValue & Me.GridControl1.CurrentCell.RowIndex
Please refer the following sample that illustates the same :
http://websamples.syncfusion.com/samples/Grid.Windows/68457/main.htmPlease have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample or send us the reproducing steps so that we could sort out the cause of the issue
and provide you a solution?
2, Regarding how to bind an external datasource
...................
Please refer the following Browser samples that shows how to virtually bind an external datasource to gridcontrol:

Let me know if you have any questions.
