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

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 control, the nodes and their children of which I populate on the server side from a DataTable.
How do I expand any node of the control upon click of it's rendered text?
Altering the TreeNodeSelectAction property of the node doesn't help.
I know that this property works for Tree View Controls that are not populated dynamically.
Any help is appreciated.
Sorry forgot getting back to this. I messed around using the built in "TreeView_ToggleNode" javascript function, that gets rendered along with the TreeView Control. Got exactly what I needed.
I have data in following two tables
Parent Mater and Child Master
In parent master there are two fields prtID and name. In child master there are three fields ID, name and prtid, The prtid is foreign key from parent master.
I want to bind data with TreeView in a windows application in c#.net
such that each child will appear inside its parent node.
Can please guide me to right direction for this task?
Looks like duplicate entry. Please do some search before making a new question :

I have a treeview control on an asp page. Everytime I select a node, be it root node or child node, the entire tree is displayed again under the tree. If I go on selecting nodes on the tree, no matter which one I select, a duplicate tree is displayed under it. I have written no events so far. It is some property that I am missing out on. Please help!
Is this tree being created on page load by any chance? If so, test (!isPostback) on PageLoad in code behind before creating it. If not, then you need to provide more code. Include details of event handlers for the control etc.
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.
