Missing _LAYOUTS folder in SharePoint Designer


Missing _LAYOUTS folder in SharePoint Designer

The _layouts folder contains Application pages, and this type of pages can’t be customized by the SharePoint Designer. If you want to customize them, you will need to have physical access to your SharePoint server since they are located in the folder C:\Program Files\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\LAYOUTS

Be aware that the files in this folder are used by ALL SharePoint sites and lists, so one change here can have a huge impact! Additionally modifying OOB Application pages is not recommended

SharePoint Application Page as Content Type


Create a Content Type
———————–

Open VS 2010

File new project–>SP2010->Content Type

Name it: MyContentTypeProject

Select Sandbox Solution

Select Item as Base Content Type

Default Code of Elements.xml

<?xml version=”1.0″ encoding=”utf-8″?>

<Elements xmlns=”http://schemas.microsoft.com/sharepoint/”&gt;

  <!– Parent ContentType: Item (0x01) –>

  <ContentType ID=”0x0100609c323354d34416a02081c618ead23f”

               Name=”MyContentTypeProject – ContentType1″

               Group=”Custom Content Types”

               Description=”My Content Type”

               Inherits=”TRUE”

               Version=”0″>

    <FieldRefs>

    </FieldRefs>

  </ContentType>

</Elements>

 

You can change below lines

 

Inherits=”FALSE”

               Overwrite=”TRUE”

 

Add some field to FieldRefs

Ex:

    <FieldRefs>

    </FieldRefs>

TO

   <FieldRefs>

      <FieldRef ID=”{DC964DD1-422F-46C5-B4FC-1A796F67DA6B}” Name=”MyMSContentType”/>

    </FieldRefs>

 

 

 

Add below Application page navigation

  <XmlDocuments>

      <XmlDocument NamespaceURI=”http://schemas.microsoft.com/sharepoint/v3/contenttype/forms/url”&gt;

        <FormUrls xmlns=”http://schemas.microsoft.com/sharepoint/v3/contenttype/forms/url”&gt;

          <New>_layouts/MyApp/MyAppNew.aspx</New>

          <Edit>_layouts/MyApp/MyAppEdit.aspx</Edit>

          <Display>_layouts/MyApp/MyAppDis.aspx</Display>

        </FormUrls>

      </XmlDocument>

    </XmlDocuments>

 

So the final Code looks like below.

<?xml version=”1.0″ encoding=”utf-8″?>

<Elements xmlns=”http://schemas.microsoft.com/sharepoint/”&gt;

  <!– Parent ContentType: Item (0x01) –>

  <ContentType ID=”0x0100609c323354d34416a02081c618ead23f”

               Name=”MyContentTypeProject – ContentType1″

               Group=”Custom Content Types”

               Description=”My Content Type”

               Inherits=”FALSE”

               Overwrite=”TRUE”

               Version=”0″>

    <FieldRefs>

      <FieldRef ID=”{DC964DD1-422F-46C5-B4FC-1A796F67DA6B}” Name=”MyMSContentType”/>

    </FieldRefs>

    <XmlDocuments>

      <XmlDocument NamespaceURI=”http://schemas.microsoft.com/sharepoint/v3/contenttype/forms/url”&gt;

        <FormUrls xmlns=”http://schemas.microsoft.com/sharepoint/v3/contenttype/forms/url”&gt;

          <New>_layouts/MyApp/MyAppNew.aspx</New>

          <Edit>_layouts/MyApp/MyAppEdit.aspx</Edit>

          <Display>_layouts/MyApp/MyAppDis.aspx</Display>

        </FormUrls>

      </XmlDocument>

    </XmlDocuments>

  </ContentType>

</Elements>

 

Deploy the application

Go to sharePoint

http://SERVER:8888/_layouts/mngctype.aspx

Go to above page under – Custom Content Types

You can find your content type.

Now add content type to List.

If you try to click new item using new content type you will get error, since you didn’t add application pages.

 

Now create application pages.

Open VS 2010àSP2010àSelect Blank Solution

Name it: MyApp

Right Click on MyApp SolutionàAdd new item

Select Application Page. Name it: MyAppNew.aspx

<table>

        <tr>

            <td>

                <asp:Label ID=”lblName” runat=”server” Text=”Name”></asp:Label>

            </td>

            <td>

                <asp:TextBox ID=”txtName” runat=”server”></asp:TextBox>

            </td>

        </tr>

       <tr>

            <td>

                <asp:Label ID=”lblProjects” runat=”server” Text=”Projects”></asp:Label>

            </td>

            <td>

                <asp:CheckBoxList ID=”cblProjects” runat=”server” RepeatDirection=”Horizontal” RepeatColumns=”4″></asp:CheckBoxList>

            </td>

        </tr>

 

      <tr>

            <td>

  <asp:Label ID=”lblEmployee” runat=”server” Text=”Category”></asp:Label>

            </td>

            <td>

                <asp:DropDownList ID=”ddlEmployees” runat=”server”></asp:DropDownList>

            </td>

        </tr>

 

    </table>

 

At

<asp:Content ID=”Main” ContentPlaceHolderID=”PlaceHolderMain” runat=”server”>

</asp:Content>

 

So Final Code will be

<%@ Assembly Name=”$SharePoint.Project.AssemblyFullName$” %>

            <td>

                <asp:TextBox ID=”txtName” runat=”server”></asp:TextBox>

            </td>

        </tr>

       <tr>

            <td>

</asp:Content>

 

<asp:Content ID=”PageTitleInTitleArea” ContentPlaceHolderID=”PlaceHolderPageTitleInTitleArea” runat=”server” >

My Application Page

</asp:Content>

 

Open .Cs file

Add below code

using System;

using Microsoft.SharePoint;

using Microsoft.SharePoint.WebControls;

using Microsoft.SharePoint.Utilities;

using System.Data;

namespace MyApp.Layouts.MyApp

{

    public partial class MyAppNew : LayoutsPageBase

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

                using (SPSite objSite = new SPSite(SPContext.Current.Web.Url))

                {

                    using (SPWeb objWeb = objSite.OpenWeb())

                    {

                        try

                        {

                            objWeb.AllowUnsafeUpdates = true;

                            SPList lstProjects = objWeb.Lists[“Projects”];

                            SPListItemCollection projItems = lstProjects.Items;

                            DataTable dtProjects = projItems.GetDataTable();

                            cblProjects.DataSource = dtProjects;

                            cblProjects.DataTextField = “Title”;

                            cblProjects.DataValueField = “ID”;

                            cblProjects.DataBind();

 

// bind to dropdown

                            ddlEmployees.DataSource = dtProjects;

                            ddlEmployees.DataTextField = “Title”;

                            ddlEmployees.DataValueField = “ID”;

                            ddlEmployees.DataBind();

 

 

                            objWeb.AllowUnsafeUpdates = false;

                        }

                        catch (Exception ex)

                        {

                            SPUtility.TransferToErrorPage(ex.Message);

                        }

                    }

                }

            }              

        }

    }

}

 

Deploy the Application as Farm solution

Now go to list which you have applied Content type.

Click New item using content type, you will get

_layouts/MyApp/MyAppNew.aspx page

Similarly add MyAppEdit.aspx, MyAppDis.aspx page to application page solution.

You can add Save and cancel button to MyAppNew.aspx page

    <tr>

            <td>

            </td>

            <td align=”right”>

                <asp:Button ID=”btnSave” runat=”server” Text=”Save” OnClick=”btnSave_Click” />

            </td>

            <td>

            </td>

            <td align=”left”>

                <asp:Button ID=”btnCancel” runat=”server” Text=”Cancel” OnClick=”btnCancel_Click”

                    CausesValidation=”false” />

            </td>

        </tr>
