    Asp:Repeater used to iterate comments as stored in umbraco..

    I am trying to display a list of comments in a thread, and have decided to use an asp:repeater to iterate over the comments in a given thread to display them. I have added properties of 'userName', 'postedDate' and 'bodyText' to the comments document type, which I am trying to pull out and display with a repearter.

    Here is my repeater:

    <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CommentRepeater.ascx.cs" Inherits="newUmb.CommentRepeater" %>
    <asp:Repeater ID="Repeater1" runat="server">
        <ItemTemplate>
        <h2>Posted by: <%#Eval("userName") %> on <%#Eval("postedDate") %></h2>
        <br />
        <%#Eval("bodyText") %>
        </ItemTemplate>
    
        <HeaderTemplate>
            <div class="comment">
        </HeaderTemplate>
        <FooterTemplate>
            </div>
        </FooterTemplate>
    
    </asp:Repeater>

    And here is my code behind:

    protected void Page_Load(object sender, EventArgs e) {
                Node thread = Node.GetCurrent();
                Repeater1.DataSource = thread.ChildrenAsTable();
                Repeater1.DataBind();
    }

    The error that I get when I try to execute this is '

    System.Data.DataRowView' does not contain a property with the name 'userName'

    I guess this is becuase I can only call generic node types using the eval thingy on the ascs control?

    So can anyone tell me how I would successfully call the node's custom properties from here? I imagine its something like the getProperty("property").Value code but need a hand in the right direction!

    Bob,

    You need to cast to Node then call getProperty 

    <%#((Node)Container.DataItem).getProperty("userName").Value.ToString()%>

    However safer way would be to create a method in code behind with signature like

    protected string GetNodeProperty(Node n, string propertyToGet){

    if(n.getProperty(propertyToGet)!=null){

    return n.getProperty.(propertyToGet).ToString();

    }

    return string.Empty

    }

    Regards

    Ismail

    Thanks Ismail,

    I used the code like this (the only difference being I have written a full library path to the node, which I'm unsure will affect anything):

     <%#((umbraco.presentation.nodeFactory.Node)Container.DataItem).GetProperty("bodyText").Value.ToString()%>

    But I am getting the following error message now:

    Unable to cast object of type 'System.Data.DataRowView' to type 'umbraco.presentation.nodeFactory.Node'.

    Any ideas?

     

    On a side note: When I high5 someone it appears to have gone whenever I refresh the page?!

    ok I got it working for me in case anyone else ever wants to do similar.

    Taking Ismail's suggestion I came up with this method to put in the code behind:

    protected string GetNodeProperty(int Id, string propToGet) {

    Node n = new Node(Id);

     

    if (n.GetProperty(propToGet) != null) {

    return n.GetProperty(propToGet).Value.ToString();

    }

    return string.Empty;

    }

     

    Which I was then able to call in the repeater like this:

    For some reason I got stuck trying to cast the node to the data row item in the repeater but was able to work around the problem this way..
