Set currentDocument property

Michele Frassetto asked on April 21, 2015 14:03

Hello, I've defined a new property, let's say "identifier", for the document type "Page (menu item)". I want to use this property in more than one web part inside the page. I use the following: {%CurrentDocument.GetValue("identifier")#%} to successfully read the property inside the web parts, but I'm not able to set the value in the c# codebehind source. I should set the value when the page loads, the web parts should read that value to correctly populate their content. I tried: protected override void OnInit(EventArgs e){ base.OnInit(e); CMSContext.CurrentDocument.SetValue("identifier", "something"); (...) but it does not work and always in the web parts I get the default value of the "identifier" property. what is the correct way to do? Best Regards

Best to get an instance of the current document and store it in it's own object, set the values and save the object. Using the CurrentDocument object is not a good idea. Have you looked at the API documentation for working with Documents/Pages?

Here is an example of the right way to get a document and update a property:

private bool GetAndUpdateDocuments()
    // Create an instance of the Tree provider first
    TreeProvider tree = new TreeProvider(MembershipContext.AuthenticatedUser);

    // Fill dataset with documents
    DataSet documents = tree.SelectNodes(SiteContext.CurrentSiteName, "/API-Example/%", "en-us", false, "CMS.MenuItem");

    if (!DataHelper.DataSourceIsEmpty(documents))
        // Loop through all documents
        foreach (DataRow documentRow in documents.Tables[0].Rows)
            // Create a new Tree node from the data row
            TreeNode editDocument = TreeNode.New("CMS.MenuItem", documentRow, tree);

            string newName = editDocument.DocumentName.ToLower();

            // Change coupled data
            editDocument.SetValue("MenuItemName", newName);
            // Change document data
            editDocument.DocumentName = newName;

            // Save to database

        return true;

    return false;
