I am trying ListDefinition and came to see the creation of List definition from content types

What is the meaning of following code?

Schema.xml

 <ContentTypes>
  <ContentTypeRef ID="0x0101005CF0DB5B6075417a8664EFD23835C831">
    <Folder TargetName="Forms/Document" />
  </ContentTypeRef>
  <ContentTypeRef ID="0x0120" /> <!--ID of folder content-->
</ContentTypes>

I have created a sample in Visual studio 2010

Steps

1.Created a contenttype project

2.added two fields and its fieldRefs in element.xml

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<Field Name="CPUFan" ID="{43AFEDFD-046C-4900-AEA1-61A2D6FC0482}" DisplayName="CPU FAN"  Type="Number"></Field>
<Field Name="CPUType" ID="{59706A25-2EF3-4AC3-B19E-2BC2CCADB527}" DisplayName="CPU TYPE" Type="Number"></Field>
<ContentType ID="0x0100e8f64d8b525043fe969f5df964e02122"
            Name="ContentTypeAnish - ContentType1"
           Group="Custom Content Types"
           Description="My Content Type"
           Inherits="TRUE"
           Version="0">
<FieldRefs>
  <FieldRef Name="CPUFan" ID="{43AFEDFD-046C-4900-AEA1-61A2D6FC0482}"/>
  <FieldRef Name="CPUType" ID="{59706A25-2EF3-4AC3-B19E-2BC2CCADB527}"/>
</FieldRefs>
</ContentType>
</Elements>

3.Then i added new item(List Definition from content type) by right clicking solution and selected above mentioned content type

schema.xml

    <ContentTypes>
  <ContentType ID="0x0100e8f64d8b525043fe969f5df964e02122" Name="ContentTypeAnish - ContentType1" Group="Custom Content Types" Description="My Content Type" Inherits="TRUE" Version="0">
    <FieldRefs>
      <FieldRef Name="CPUFan" ID="{43AFEDFD-046C-4900-AEA1-61A2D6FC0482}" />
      <FieldRef Name="CPUType" ID="{59706A25-2EF3-4AC3-B19E-2BC2CCADB527}" />
    </FieldRefs>
  </ContentType>
</ContentTypes>
<Fields>
  <Field Name="CPUFan" ID="{43afedfd-046c-4900-aea1-61a2d6fc0482}" DisplayName="CPU FAN" Type="Number">
  </Field>
  <Field Name="CPUType" ID="{59706a25-2ef3-4ac3-b19e-2bc2ccadb527}" DisplayName="CPU TYPE" Type="Number">
  </Field>
</Fields>

what is the difference between the two schemas?

1 Answer 1

Reset to default

The difference is very simple

First Schema.xml is

Creating a list definition using

Folder content type

whose id is

0x0120

second schema.xml is

creating a list definition using your custom content type whose id is

0x0100e8f64d8b525043fe969f5df964e02122

I have a blog on this topic. Hope it could bring some light on it

  • The first schema is also refering a custom content type.see <ContentTypeRef ID="0x0101005CF0DB5B6075417a8664EFD23835C831">.That is why it is using ContentTypeRef.Am i right?

  • nice to know what content type you selected while creating the first site definition? which generated the first schema.

  • See i have only one list definition.I have no idea about site definition.I want to know that is it possible to use different content types in one list Definition?Is it possible to add fields in schema.xml and refer this in element.xml?
