Member	srizzetto-microgate - 7/5/2010 11:59:25 AM Retrieve parent document name Is there a method to retrieve the parent's document name of a specific nodelevel ? Eg. I have this tree: Menu1 Menu1.1 Menu1.1.1 Menu1.1.1.1 Menu1.1.1.2 Menu1.1.2 Menu2 Menu2.1 .. If I am in one of the red Menu1.1.x page (3rd, 4th, etc level) I want to retrieve my "root" father (in this case Menu1.1) thanks

RE:Retrieve parent document name

Hello.

You can use following code and compose cycle (while () {} ) to get requested design.

1. Get current node´s parentID:

CMS.CMSHelper.CMSContext.CurrentDocument.NodeParentID;

2. Get parent according to its NodeParentID via:

CMS.WorkflowEngine.DocumentHelper.GetDocument(Int32, TreeProvider)

You need TreeProvider as it is described here: http://devnet.kentico.com/docs/devguide/selecting_nodes.htm

3. Repeat selection above until current node´s NodeLevel property is requested value.

RE:Retrieve parent document name

Thanks Radek,
it is exactly what I did. I created a usercontrol with a asp:literal in it and with this recursive code (RootLevel is a public property to set which level of "father" I want to obtain)

Hope it helps to someone else



using CMS.TreeEngine;
using CMS.CMSHelper;

public partial class MicrogatePortal_CMSTemplates_UserControls_RootDocName : System.Web.UI.UserControl
{
    private int _rootLevel = 2;
    public int RootLevel
    {
        get { return this._rootLevel; }
        set { this._rootLevel = value; }
    }

    
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            if (CMSContext.CurrentDocument.NodeLevel <= _rootLevel)
                lit.Text = CMSContext.CurrentDocument.DocumentName;
            else
                FindRoot(CMSContext.CurrentDocument.NodeParentID);
            
        }
    }

    private void FindRoot(int nodeID)
    {

        CMS.TreeEngine.TreeNode tn = CMS.CMSHelper.TreeHelper.SelectSingleNode(nodeID);

        if (tn != null)
        {
            if (tn.NodeLevel == _rootLevel)
                lit.Text = tn.DocumentName;
            else
                FindRoot(tn.NodeParentID);
        }


    }

    
}
