c# - No Default.aspx.designer.cs files in my ASP.NET project -

my current web site not have designer.cs files. (yes not web application)

the site complete added 2 clases site , when want make use of gridview tells me this:

this because wrapped code same namespace in classes so....

  namespace samraswebportalsql   {      public partial class gridview : system.web.ui.page    {     protected void page_load(object sender, eventargs e)     {         functions.removecaching(this);         loadgrid();      }      private void loadgrid()     {         dataset dataset = sqlhelper.getdataset("select * company");         functions.bindgridview(gridview1, dataset);     }     } } 

i know need following code in .designer.cs file since dont have 1 cant place anywhere ells?

protected global::system.web.ui.webcontrols.gridview gridview1; 

in "web site", can add new aspx page (web form). , in web form can drag gridview onto page. once you've given id this:

<div> <asp:gridview id="grid1" runat="server"></asp:gridview> </div> 

you can go code behind , this:

protected void page_load(object sender, eventargs e) {     grid1.datasource =..; } 

if put code behind in different class name or namespace, need tell web form find it. chaning inherits property of page directive this:

<%@ page language="c#" autoeventwireup="true" codefile="default2.aspx.cs" inherits="samraswebportalsql.gridview" %>
