    How do i update an Umbraco Node's property value from the code behind?

    API Questions

    Hello,

    I've been stuck on this for a day now.

    How can i update a Node's property from the code behind for ASP.Net?

    All the umbraco.library.NodeFactory.Node methods are Get's, none seem to set a property value.

    I tried to update the value in the database directly which seems to work, but because i dont know how to publish the content from my code behind the vlaue gets ignored.

    Any help will be greatly appreciated!

    Many thanks
    Mike

    Hi,

    nodeFactory.Node is for published xml only, so it's always readonly. if you need to update a doc's property, use

    var doc = new Document(1234);
    doc.GetProperty("propertyAlias").Value = newValue;
    doc.Save();

    Cheers,

    /Dirk

    Thanks dirk thats a big help.

    When i use the above it changes the value in umbraco which is cool but it doesnt publish the item so the value on the site does not change. Should i use doc.Publish after doc.Save?

    If so it asks for a user, what user should i pass in?

    Thanks,

    Mike

    Hi,

    btw, if you have uComponents installed, you can also use uQuery methods to set property values:

    using uComponents.Core;
    using uComponents.uQueryExtensions;

    Node node = uQuery.GetCurrentNode();
    node.SetProperty("propertyAlias", valueObject);
    node.Publish(true);

    HTH,

    Hendy
