Add GUID Column in datagrid

[Melson]

Hi

I've created a GUID column of a table in ms sql server and bind the table to
a datagrid. How can I automatically create new GUID when i add new row in
the datagrid.

Pls help. Thanks.

If the table is bound, add the row to the table.

Dim g As New Guid
Dim dg As New DataGrid
Dim t As New DataTable
Dim c As New DataColumn("MyGuid")
Dim r As DataRow = t.NewRow()

t.Columns.Add(c)
r(0) = g
t.Rows.Add(r)

Hi,

To tell if you are on new row
http://64.78.52.104/FAQ/WinForms/FAQ_c44c.asp#q823q

You will have to manually change the value for guid column to Guid.NewGuid
