Datagrid on Webform - How to update? Help

[Ash]

Hi,

I'm using Vb.NET webform, connecting to sql server database on the local
machine. I used datagrid propery builder to add the edit, update and cancel
colum. On the code, i have:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
SqlDataAdapter1.Fill(DataSet11)
DataGrid1.DataBind()
End Sub

When i run the page, i can see the content on the browser, but when i click
on update, nothing happens.
Any tips/ideas how i can do the update?

Thanks,
Ash
