JSOM: Alter a column’s ShowInDisplayForm property

When you create a content type, you can define if your fields will be shown in DisplayForm, EditForm, NewForm. You can hide or show them, just as Yaroslav Pentsarsky says. If your list is already provisioned, you can change them with Server Object Model, why not in PowerShell: Technet: Setting ShowInDisplayForm, ShowInEditForm, ShowInNewForm properties with powershell.

If you don’t have access to the server, then the same can be done with JSOM. Here is the code:

var ctx = SP.ClientContext.get_current(),              //SP.ClientContext
    field = ctx.get_web()                              //SP.Web
               .get_lists()                            //SP.ListCollection
               .getByTitle('MyList')                   //SP.List
	       .get_fields()                           //SP.FieldCollection
	       .getByInternalNameOrTitle("Site");      //SP.Field
ctx.load(field, "SchemaXml");                          //load only SchemaXml
ctx.executeQueryAsync(function() {
	var s = field.get_schemaXml(),
	    s1 = s.replace('ShowInDisplayForm="FALSE"', 
                           'ShowInDisplayForm="TRUE"');
	field.set_schemaXml(s1);
	field.update();
	ctx.executeQueryAsync();
});

Next: JSOM: Alter a column’s DisplayName.

AfterProperties kräver InternalName

AfterProperties kommer inte leda till Exception, men de kommer returnera bara null, om du använder DisplayName. Man måste ha InternalName. Här är ett litet exempel på hur man kan få ut värden före och efter uppdateringen. Exemplet har testats i ItemUpdated-eventreceiver.

var before = properties.BeforeProperties;
var after = properties.AfterProperties;
var contentDisplayName = "News Content";
var list = properties.List;
var contentInternalName = list.Fields[contentDisplayName].InternalName;
var contentBefore = before[contentInternalName];
var contentAfter = after[contentInternalName];

Här är en hel lista över olika typer som Field kan få i Content Type. Type=”File” motsvarar SPFieldFile

ID på befintliga kolumner

Det finns en fin lista över id på kolumner som man kan lägga till. Här är ett exempel hur man kan använda det.

Här är ett exempel på två extra kolumner i contenttype:

    
<FieldRefs>
      <FieldRef ID="{23f27201-bee3-471e-b2e7-b64fd8b7ca38}"/>
      <!-- Enterprise Keywords-->
      <FieldRef ID="{3de94b06-4120-41a5-b907-88773e493458}"/>
      <!-- PublishingImage-->
 </FieldRefs>

Komma åt Title-kolumnen i SPList

Vad gör man om man vill lägga till Title-kolumnen till en ny vy?

SPField fieldTitle = scheduleList.Fields["Title"];

Det kommer funka, men Title kommer vara bara text, utan en länk till SPListItem.

Kolla på den koden:

SPField fieldTitle = scheduleList.Fields[SPBuiltInFieldId.LinkTitle];

Här hämtar vi kolumnen som heter i Sharepoint “Title linked with item menu”. Det finns fler sådana “inbygda” kolumner.
