As of a previous question, whenever an item is added in a list, I create a document library based on a template, and set defaultvalues for some of its fields. In Sharepoint Manager I see defaultvalues correctly set, but if I add an item to the document library, the fields are not filled with their expected default values: any hint? I am running Sharepoint Foundation 2013. This is the code:

public override void ItemAdded(SPItemEventProperties properties)
{
    SPWeb myWeb = properties.Web;
    string projectName = properties.ListItem["Project Name"].ToString();
    var customTemplate = myWeb.ListTemplates["ProjectTemplate"];
    Guid myItemGuid = myWeb.Lists.Add(projectName , projectName , customTemplate);

    SPList myItem = myWeb.Lists[myItemGuid];

    var projectCategoryField = myItem.Fields["Project Category"];
projectCategoryField.DefaultValue = "Test default value";
    projectCategoryField.Update();

    properties.ListItem.Update();
    base.ItemAdded(properties);
}

    I forgot to update the code sample according to your answer in that other question - that part was ok. The issue stated here is different - code is working but default value don't get filled. – En-j Apr 20 '15 at 11:07
  • no need to create an exact duplicate of your previous question then. I would suggest that you delete this one and edit your other one – MdMazzotti Apr 20 '15 at 11:34

There was not an issue with the code nor the Sharepoint edition. The issue was a somewhat scrambled list template, with multiple duplicate content types. I recreated it and everything is OK.

This should work for you.
You have to call the .Update() on the field not on the list.

public override void ItemAdded(SPItemEventProperties properties)
{
    SPWeb myWeb = properties.Web;
    string projectName = properties.ListItem["Project Name"].ToString();
    var customTemplate = myWeb.ListTemplates["ProjectTemplate"];

    myWeb.Lists.Add(projectName , projectName , customTemplate);
    SPList myItem = myWeb.Lists[projectName];

    //Is the field Project Category in your customTemplate
    SPField projectField= myItem.Fields["Project Category"];
    projectField.DefaultValue = "Test default value";
    projectField.Update()

    //properties.ListItem.Update();
    base.ItemAdded(properties);
}
  • Thank you, actually the code included Update() on the field - I forgot to update the code sample. – En-j Apr 20 '15 at 11:03
