If you need to execute a subroutine (assume server side), then you need a button control rather than a hyperlink.

You can use a linkbutton (which renders as hyperlink) and in its click event

mySubroutine()  'execute your subroutine
Response.Write("alert('Things are done!')")   'show your message box

Hope that helps

Oops, it should be

Response.Write("<script>alert('Things are done!')</script>")   'show your message box

Sorry about forgetting the script tag!

Is your "hyperlink" inside a datagrid or similar databound controls?  You say you want passing some parameters into the subroutine.  Where do the values of the parameters come from?  Some textboxes, a constant or else?

Firstly add a ButtonColumn in your datagrid like this.

<asp:datagrid id="DataGrid1" runat="server" AutoGenerateColumns="False">
<Columns>
  <asp:BoundColumn DataField="col1"></asp:BoundColumn>
  <asp:BoundColumn DataField="col2"></asp:BoundColumn>
  <asp:BoundColumn DataField="col3"></asp:BoundColumn>
  <asp:BoundColumn DataField="col4"></asp:BoundColumn>
   <asp:ButtonColumn Text="Link" CommandName="doSub"></asp:ButtonColumn>
</Columns>
</asp:datagrid>

Then add a handler for the ItemCommand event

Private Sub DataGrid1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.ItemCommand
        If e.CommandName = "doSub" Then
            doSubroutine(e.Item.Cells(0).Text, e.Item.Cells(1).Text)
        End If
End Sub

Oh I forgot you need a message popup.

Private Sub DataGrid1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.ItemCommand
        If e.CommandName = "doSub" Then
            doSubroutine(e.Item.Cells(0).Text, e.Item.Cells(1).Text)
            Response.Write("<script>alert('Success')</script>")
        End If
End Sub
