How do I expand a node (parent node) in an ASP.NET Dynamic TreeView Control upon click of the text of the node?

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.

Adding Data grid view as a child node in a Tree View

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

How to make child node of a treeview control to make panel control visible

how to write a click event for a child node of a tree view control...
if i click the child node a static panel should be visible.

As far as I know , the only way is to programatically tell which node is selected (retrieve the appropriate node via the e.Node parameter), then fire the corresponding functionality.
This code can be placed within TreeView.AfterSelect event.

Treeview asp.net

I have a treeview control on an asp.net page. Everytime I select a node in the tree, a duplicate copy of the tree is displayed under it. I am unable to understand. I have not written any code so far. I'm probably missing out on some property that I should have set. No matter which node I click on another tree is displayed under the existing tere. Please help!

It sounds like you're adding the Treeview to the page on Page_Load without testing if it's a Postback or not.
If it's a Postback then the Treeview will be automatically added to the page as the WebForm reconstructs itself.
Try this:
void Page_Load() {
if( !Page.IsPostback ) {
// code to add treeview to page
}
}
That said - I strongly advice staying away from the WebForms Treeview control (and generally speaking, anything in the System.Web.UI.WebControls namespace - except for Literal and PlaceHolder) because they take away too much control from the developer and often end up wrecking the user experience. The WebControls library was originally designed around IE6, many years ago.
If you're starting a new project I strongly recommend you take a look at ASP.NET MVC instead.

Treeview prevent Node collapse

I have a .net 2.0 C# Project.
I have a Treeview with 2 Nodes, each of them has many child nodes.
When you click on a child node, a PDF is displayed in a webbrowser control depending on the properties of the node.
Fine, but the problem is that when both Nodes are expanded, and I click on a child node, the other node gets collapsed! I don't have any code that collapses any node of the treeview, but somehow it happens! I also had a look at the BeforeCollapse Event, but somehow it doesn't fire, alltough the other node collapses!
Can anyone imagine why this happens?
I would be very grateful if anyone can teach me how to prevent this happening!
Thank you very much!

I stopped using the WinForms TreeView some time ago because of it's limits and quirks.
My favorite replacement is the open-source TreeViewAdv:
TreeViewAdv on Source Forge
TreeViewAdv on CodeProject

This happens if the TVS_SINGLEEXPAND style is ON for the treeview. Try setting the HotTracking property to false.
