On the Page_Load the Attribute IS set correctly.
So that on NodeExpand of the top level the myPC node is created.
However, the Attributes.Add in NodeExpand does not set the attributes.
Therefore NEXT time it comes into expand, Drive node is NOT created.
Is this a bug?
| protected void Page_Load(object sender, EventArgs e) |
| { |
| if (!Page.IsPostBack) |
| { |
| RadTreeNode rootNode = new RadTreeNode("Computers"); |
| rootNode.Attributes.Add("type", "ROOT"); |
| rootNode.Value = "ROOT"; |
| rootNode.ImageUrl = "~/TreeView/Img/WindowsXP/6myNetworkPlaces.gif"; |
| rootNode.Expanded = true; |
| rootNode.ExpandMode = TreeNodeExpandMode.ServerSideCallBack; |
| RadTreeView1.Nodes.Add(rootNode); |
| } |
| } |
| protected void RadTreeView1_NodeExpand(object sender, RadTreeNodeEventArgs e) |
| { |
| if (e.Node.Attributes["type"] == "ROOT") |
| { |
| RadTreeNode node = new RadTreeNode("mypc"); |
| node.Attributes.Add("type", "COMPUTER"); |
| node.Value = "COMPUTER"; |
| node.ImageUrl = "~/TreeView/Img/WindowsXP/2PCRemote.gif"; |
| node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack; |
| e.Node.Nodes.Add(node); |
| return; |
| } |
| if (e.Node.Attributes["type"] == "COMPUTER") |
| { |
| RadTreeNode node = new RadTreeNode("C"); |
| node.Attributes.Add("type", "DRIVE"); |
| node.Value = "DRIVE"; |
| node.ImageUrl = "~/TreeView/Img/WindowsXP/15hardDisk.gif"; |
| node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack; |
| e.Node.Nodes.Add(node); |
| } |
| } |

Hi Martin Smith,
The only problem in your project is using the "type" keyword for Custom Attributes. You should avoid using names of custom attributes which are valid html attributes. I just replaced the "type" with "type1" and the project is working now.
You may read this article for a list of some of the custom attributes you should avoid.
Hope this helps.

Hi Martin Smith,
I'm attaching the edited code as a .zip file. You may try it on your own.
It works OK by only changing the custom attributes from "type" to "type1".
Hope this helps.
