Can kendo treeview be filtered based on parent Node text?? I have a treeview with user name as parent node and user details as child nodes. I need to perform a search based on User name.
Please help
No built-in or easy way to do this. The treeview is composed of multiple dataSources for each branch. So you need o recursively iterate through all the children dataSources and use their filter method.

I have a TreeView which data source is generated in runtime through code to which I don't have access. Its hierarchical data, nodes of tree with 2, 3 or 4 depth levels. I have to make the same structured tree with RadioButtons corresponding to every object in first tree. Is there a way to iterate through every element of TreeView or another method to do my task?
In WPF, we use DataTemplates, or in your case HierarchicalDataTemplates to define how our data should be presented. You already have the data in the first TreeView and that should be accessible from its ItemsSource or Items properties. Therefore, all you need to do is to define another HierarchicalDataTemplate to display the same data object the way that you want it. There is no need to manually iterate through all of the nodes from the original TreeView.
Basically, I'm working on a winforms application. Now I'm stuck in a problem in which I want a tree grid view that displays nodes in DataGridView. I already used customized DataGridView that that displays child nodes. But what I want is to add another DataGridView in a child node. Meaning, when a user expands a node, a data grid view displays as a child node. Please help me.
Have a look at the following code project article in which a Dropdown box is added as a treenode item. The article extends the TreeNode and adds a ComboxBox. It should be fairly simple to extend to a DataGridView

I am using MVVM for a WPF app and I have a Telerik RadTreeView, and when I collapse a parent, I'd like to recursively collapse all children (and their children, etc) so that when I expand the parent again, I don't see any grandchildren, because all children are collapsed. Is there a property of the RadTreeView that Can accomplish this, or any relatively easy alternative way? Thanks.
Stumbled across this question searching for some other RadTreeView related topics.
Based on the current Telerik RadTreeView Documentation:
When you need to expand or collapse all the items recursively for a given item use the ExpandAll() and CollapseAll() methods of the RadTreeViewItem respectively. When you need to expand/collapse all the nodes in the tree use ExpandAll() and CollapseAll() methods of the RadTreeView.
Is is possible to display a node without children as a leaf node within the .NET 3.5 TreeView control?
I have a treeview that displays a list of companies as nodes which would each display leaf nodes for documents belonging to that company.
If a company exists without any documents I would still like it to be rendered as parent (folder) but it renders as a leaf (file).
I could add a "No Documents" node to the company but this seems ugly and would add overhead to manage whether or not the node is there or should be added.
There doesnt seem to be any properties on TreeNode that would help here
Any ideas?
Thanks
The only way I discovered to resolve this issue is to add a "No Document" leaf to any empty parent folder
I have a Silverlight project where the main objects are just a bunch of nodes that are joined to each other. A parent node can have many children.
I want to be able to bind the nodes to an itemscontrol or similar and so was wondering how to best structure the parent child relationship.
Is it OK to create a flat top level list of all nodes (List allNodes) and add each node to that, binding the list to the itemscontrol, then on top of that add each node to it's parent's 'childnodes' list to establish the structure - or am I doing some kind of ugly doubling up?
Just hoping there is some kind of best practice or pattern I can latch on to
Thanks
You should use the treeview found in the official silverlight toolkit. Here is an online demo.
