    Setting the value of MultiNodeTreePicker2 programatically

    Hello there!

    Been searching and trying to implement this for some time now. I would like to programatically set the value of a Umbraco.MultiNodeTreePicker2 datatype.

    Here's the code I've tried:

    /// <summary>
/// Create an Exercise
/// </summary>
/// <param name="parentId"></param>
/// <param name="model"></param>
private void CreateExercise(int parentId, Exercise model)
{
    // UserId of the Umbraco admin
    int userId = 0;
    // Get the Umbraco contentService
    var cs = Services.ContentService;

    // Create the node
    var content = cs.CreateContent(model.Name, parentId, "Exercise", userId);

    // Set custom properties
    content.SetValue("content", model.Content);
    content.SetValue("imageUrl", model.ImageUrl);

    // Entering as a CSV
    var testArray = model.BodyParts.Select(b => b.Id).ToArray();
    content.SetValue("bodyParts", string.Join(",", testArray));

    // Entering as a IENumerable<IPublishedContent>
    //content.SetValue("bodyParts", model.BodyParts);

    // Save the node
    cs.SaveAndPublishWithStatus(content);
}

    Unfortunately, neither CSV or IENumerable

    What sort of datatype should the data be when setting the value of the MultiNodeTreepicker?

    Thanks!

    Hi Thomas

    I think you need to set list of "Udi"s

    Udi is new format of ids, and MultiNodeTreePicker2 stores data like list if Udis.

    Thanks,

    Alex

    Hey there Alex, thanks for your reply.

    That spurs another question; how does one get the UDI of an IPublishedContent? Documentation does't seem to define this anywhere yet.

    Hi Thomas

    It should be something like:

    var node =
ApplicationContext.Services.ContentService.GetById(3232);

var locaUdi = Udi.Create(Constants.UdiEntityType.Document, node.Key);

    IPublishedContent returns empty Guid, but it works with an entity from the database.

    Thanks,

    Alex

    Thank you Alex, solved the issue.

    This is how i ended up implementing it:

    // Get all the body parts
IEnumerable<IContent> bodyParts = cs.GetDescendants(1334);

// Construct the array of strings to search for in Umbraco, then create a list of the UDI's
string[] bodyPartsSearch = new string[] { "Fødder", "Ben" };
model.BodyParts = bodyParts.Where(b => bodyPartsSearch.Contains(b.Name)).Select(n => Udi.Create(Constants.UdiEntityType.Document, n.Key));

    Then, in the CreateExercise method (to save it), i did this:

    var bodyPartsArray = model.BodyParts.Select(b => b.ToString()).ToArray();
var bodyParts = string.Join(",", bodyPartsArray);

content.SetValue("bodyParts", bodyParts); // Should look like this: "umb://document/9ac2abf298964ec2b660adf6bd2e6877,umb://document/9f886d3aa0794990bcf795114b3203c4"

    Have an awesome day!

    Just encountered this. I would have expected some helper methods in the ContentService to deal with this, but in the meantime I wrote these two handy extension methods that convert a list of content to a CSV string suitable for using with content service:

    /// <summary>
/// Converts a list of published content to a comma-separated string of UDI values suitable for using with the content service
/// </summary>
/// <param name="content">The published content</param>
/// <returns>A CSV string of UID values eg. umb://document/56c0f0ef0ac74b58ae1cce16db1476af,umb://document/5cbac9249ffa4f5ab4f5e0db1599a75b</returns>
public static string ToUdiCsv(this IEnumerable<IPublishedContent> content)
{
    return String.Join(",", content.Select(c => Umbraco.Core.Udi.Create(Umbraco.Core.Constants.UdiEntityType.Document, c.GetKey())));
}

/// <summary>
/// Converts a list of content to a comma-separated string of UDI values suitable for using with the content service
/// </summary>
/// <param name="content">The content</param>
/// <returns>A CSV string of UID values eg. umb://document/56c0f0ef0ac74b58ae1cce16db1476af,umb://document/5cbac9249ffa4f5ab4f5e0db1599a75b</returns>
public static string ToUdiCsv(this IEnumerable<IContent> content)
{
    return String.Join(",", content.Select(c => Umbraco.Core.Udi.Create(Umbraco.Core.Constants.UdiEntityType.Document, c.Key)));
}

    Usage is something like:

    var cs = Services.ContentService;

var nodes = Umbraco.TypedContent(1234).Children(); // IEnumerable<IPublishedContent> 

var content = cs.GetById(567);

content.SetValue("content",  nodes.ToUdiCsv());

    I think IPublishedContent GetKey() gets an empty GUID, i dont know why. It should work with IContent.

    Seems to work OK with IPublishedContent when I've tried it....
