Question:
I have a default.aspx in a folder _layouts/sandbox on the sharepoint server.
It has the following code:
using System; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using System.Web.Configuration; namespace sandbox { public partial class _Default : LayoutsAppPage { protected void Page_Load(object sender, EventArgs e) { SPWeb web = SPContext.Current.Web; LabelTitle.Text = web.Title; if (Page.IsPostBack == false) { //Label1.Text = "Fahrenheit to Celsius:"; } } protected override void OnPreInit(EventArgs e) { base.OnPreInit(e); try { this.MasterPageFile = SPContext.Current.Web.MasterUrl; } catch { } } } } it is supposed to inherint the LayoutsAppPage class so that I can use that to do the OnPreInit functions in all pages in the 'sandbox' application. here is the code to LayoutsAppPage.aspx.cs in the same directory
using System; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using System.Web.Configuration; namespace sandbox { public class LayoutsAppPage : System.Web.UI.Page { protected override void OnPreInit(EventArgs e) { base.OnPreInit(e); try { this.MasterPageFile = SPContext.Current.Web.MasterUrl; } catch { } } } } i get the following error when running the page
c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\LAYOUTS\sandbox\Default.aspx.cs(20): error CS0246: The type or namespace name 'LayoutsAppPage' could not be found (are you missing a using directive or an assembly reference?)
at System.Web.Compilation.AssemblyBuilder.Compile()
i did notice that in the line "public partial class _Default : LayoutsAppPage" that LayoutsAppPage does not turn light blue like it should for the base class. If the line is "public partial class _Default : System.Web.UI.Page" the page loads fine. maybe i've declared the basepage incorrectly?
edit: by request -

Solution:1
If your assembly is deployed to the GAC or signed with public key, then you will have to specify the inherits attribute of your Page element to use the full type & assembly name such as below:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="_Default.aspx.cs" Inherits="CustomAssemblyNamespace.sandbox._Default, CustomAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1a01d56a735c19c1" %> Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
