I've a gridview with a delete button on each row. When I click the button on a row, I want to delete that row from the Gridviewand from the database. The Gridview is bound to a table of my access database. Below you can find the code of my Gridview.

Thanks,

supported to informaniac comment .. need to add this in access datasource
 DeleteCommand="DELETE FROM xxxx
                 WHERE ID=@ID"

also need to add DataKeyNames in your grid control so as per sample it would be
<asp:GridView ID="grdAbsentismo" runat="server" DataKeyNames="ID"  AutoGenerateColumns="False" DataSourceID="GridDataSource" BorderColor="Black" BorderStyle="Solid" BorderWidth="1px" CellPadding="4" ForeColor="#333333">

Can you be more explicit please? I've started using ASP just a few days ago...

Thanks,

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

The easy way (I think) is to remove that buttonfield and add a command field(delete). Then change the "delete" text to "remover" and the button type to "button" (instead of link)
Don't forget you need to have a primary key field!
