Check node in Treeview On Demand

[Meaning Of Lights]

Hi,

I've almost got this Treeview Loaded On Demand working!!

My last question is how do you check a node that you load on-demand. I've tried CheckState, Checked, Checkable but no luck.

I cant find a sample that demonstrates how to check a node loaded on demand


My aspx:

  <telerik:RadTreeView runat="server" ID="RadTreeView1"
             OnNodeDataBound="RadTreeView1_NodeDataBound" CheckBoxes="true" CheckChildNodes="true"  
            LoadingStatusPosition="None" PersistLoadOnDemandNodes="false" EnableViewState="false"
            Style="float: left" OnClientNodeClicked="onNodeClicked" Width="300px">
            <WebServiceSettings Method="GetTreeViewNodes" Path="~/PopulateTreeview.asmx" />
            <Nodes>
             
            <telerik:RadTreeNode Text="mgpage_BalanceSheet" Checked="true" Value="1" ExpandMode="WebService"> </telerik:RadTreeNode>
            .....


My Code behind:

[WebMethod(EnableSession = true)]
        public List<NodeData> GetTreeViewNodes(RadTreeNodeData node)
        {
            DataTable dt = Helper.ConfigurationHelper.GetCofiguration(node.Text);
            List<NodeData> nodes = new List<NodeData>();
            NodeData nodeData = new NodeData();
            foreach (DataRow dr in dt.Rows)




 foreach (DataRow dr in dt.Rows)
            {
                nodeData = new NodeData();
                nodeData.Text =  dr["DisclosureCode"].ToString();
                nodeData.Value = dr["DisclosureCodeId"].ToString();
                nodeData.ExpandMode = TreeNodeExpandMode.WebService;
                nodeData.CheckState  = TreeNodeCheckState.Checked;
                nodeData.Checkable = true;
                nodeData.Checked = true;
                nodes.Add(nodeData);


        public class NodeData
        {
            public string Value { get; set; }
            public string Text { get; set; }
            public TreeNodeCheckState CheckState { get; set; }
            public bool Checked { get; set; }
            public bool Checkable { get; set; }
            
            public TreeNodeExpandMode ExpandMode { get; set; }
        }



thanks in advance

recommends the latest Telerik DLL 2008.3.1105.35 and that resolves the problem.. no wonder it was doing my head in.

I see the FindNodeByText and FindNodeByValue, have second boolean parameter ignoreCase.. unfortunalely with the latest DLL I can still produce the StackOverFlow

Hi Jeremy,

I am glad that the problem with the Checked property is now resolved.

As for the other problem with FindNodeByText and FindNodeByValue methods I noticed that you have opened another post, so lets close this one.
