Content Type - Setting up default content type programmatically

Content Type - Setting up default content type programmatically

  • Comments 6

Here’s the sample to add and set a new content type as a default content type to a document library in a SharePoint site.  Also this will hide the pervious default content type.


SPSite oSPSite = new SPSite(""); // Site URL
SPWeb oSPWeb = oSPSite.OpenWeb();
SPList list = oSPWeb.Lists["Shared Documents"];  // Name of the List
SPContentType newContentType2 = oSPWeb.ContentTypes["ContentType_Two"]; // ContentType Two’s name
SPContentTypeCollection currentOrder = list.ContentTypes;
List<SPContentType> result = new List<SPContentType>();
foreach (SPContentType ct in currentOrder)
    if (ct.Name.Contains("ContentType_Two"))
list.RootFolder.UniqueContentTypeOrder = result;

  • Hi,

    I really appreciate the post u uploaded i.e. the content type order. changing . this displays the the order the way whatever we set in Unique content type order  property. but i am having a problem is that.. When i upload a file then it select last uploaded files content type in  Content type drop down even if that contentTypeitem is second or third number in Content type drop down.  This not select first item.  U getting me.  it must select First item in content Type drop-down.

    My contents type are === Audio, video, Image and Document.

    Thanks in advance ... please reply
