    Hi guys,
    Ultimately, I am trying to build an xml string from the checked nodes in the treeview, though I'm having issues trying to retrieve the text and value fields from checked nodes when I have the treeview control bound to a sitemapdatasource and I was hoping you could help me out.
    Thanks in advance!


    My code-behind looks like:
    StringBuilder pagecfg = new StringBuilder();
    pagecfg.AppendLine("<pageconfig>");
    IList<RadTreeNode> nodeCollection = rtvSitemap.CheckedNodes;
    foreach (RadTreeNode node in nodeCollection)
    {
        pagecfg.AppendLine(string.Format("<page title='{0}' url='{1}' />",node.Text, node.Value));   
    }
    pagecfg.AppendLine("</pageconfig>");

    Where the sitemap file looks like:
    <siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" enableLocalization="true">
    <siteMapNode title="$resources:SiteMapLocalizations,HomePageTitle" url="~/default.aspx" description="$resources:SiteMapLocalizations,HomePageDescription" Expanded="false" />
    <siteMapNode title="$resources:SiteMapLocalizations,PartSectionTitle" url="" description="$resources:SiteMapLocalizations,PartSectionDescription" Expanded="true" >
    <siteMapNode title="$resources:SiteMapLocalizations,PartPageTitle" url="~/Pages/Production/ProdPart.aspx" description="$resources:SiteMapLocalizations,PartPageDescription" SecAccess="Production" />
    </siteMapNode>
    </siteMap>

    My markup is as follows:
    <telerik:RadTreeView ID="rtvSitemap" runat="server" DataSourceID="dsSiteMap" CheckBoxes="true" MultipleSelect="true" CheckChildNodes="True" DataModelID="Title" DataNavigateUrlField="Url">
                                    <DataBindings><telerik:RadTreeNodeBinding Expanded="true" TextField="title" ValueField="url" /></DataBindings>
                                </telerik:RadTreeView>

    I forgot to mention the main issue is that values in this line returns empty strings.
    pagecfg.AppendLine(string.Format("<page title='{0}' url='{1}' />",node.Text, node.Value));

    Hello,

    I am afraid that there is no property in your sitemap node objects to indicate which nodes are checked and therefore the collection of your checked nodes is empty. It seems that all your nodes are considered unchecked and therefore the collection is empty.
