javascript alert incorporating with asp code-behind

I have a function in an asp.net page that will delete a record from a database. I need to have a message pop up to confirm deletion. I have searched google and everywhere for about 2 hours now, hoping to find something.

It looks like everyone is saying i need javascript or vbscript to pop open the alert. However i'm unable to figure out how i can have a button on my asp.net page have the onClick event equal a javascript and then have the "OK" on the javascript popup call the asp.net function for deletion.

Does anyone know how i can do this?

Here is the code I wrote that I use with the datagrid:

Code:

---

private void grdBooks_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
        if(e.Item.ItemType != ListItemType.Header && e.Item.ItemType != ListItemType.Footer)
        {
                LinkButton delete = (LinkButton)e.Item.Cells[e.Item.Cells.Count-1].Controls[0];
                delete.Attributes["onclick"] ="javascript:return confirm('Are you sure you want to delete "
                        + DataBinder.Eval(e.Item.DataItem, "Title") + "?')"; 
        }               
}
