I want to create a treeview with dropdown lists. In fact, I need to add DropDownList to the TreeNode. I've done this with WPF but I couldn't find a way to do that on Windows forms control. Is it possible to customize the TreeNode control in order to add
a dropdown box?

How to make a treenode as the 1st child node for every parent node or for some specific parent nodes.
thanks in advance
i have a treeView which display organization chart as hierarchical view. i want when end-user remove a treeNode, all childs of the selected node also being removed and then update database. to do this, i've used this code :
private void btnDeleteReceiver_Click(object sender, EventArgs e)
private void DeleteNode(TreeNode node)
foreach (TreeNode childNode in node.Nodes)
TestDataSet.ReceiversRow receiver = node.Tag as TestDataSet.ReceiversRow;
as u see in above code, i have a recursive method which delete all child nodes of the parentNode. but i'm facing a problem to delete all childs of the node. this loop could not iterate all childs node correctly. i don't know
Like in Windows Explorer, when the specific treenode is partially visible and the mouse is hovered over, the tooltip like text window will appear.
Just wondering is there a similar build-in functionality in treeview?
From what I understood, this text window seems not a tooltip control per se. What is it and how it is implemented?

I bind xml to treeview and select the node.I write code as
XmlNode xnParent = TreeView1.SelectedNode.Parent; XmlNode xnchild = TreeView1.SelectedNode;
But i got error these places.
Error 1 Cannot implicitly convert type 'System.Web.UI.WebControls.TreeNode' to 'System.Xml.XmlNode' E:\SVN_WORK1\Projects\Server\VegaFABSWeb\Admin\DataDictionary.aspx.cs 36 28 E:\...\VegaFABSWeb\
I use a TreeView to display a sitemap, but I wanted next to every link a small image; when clicked, it would add the link to a list of favorites in the Profile of the site user.
So I made a custom TreeNode, but I cannot figure out how to make the image postback to the page and expose an event that I can capture and use to add the link to the Profile.
Looked around here and via google, but somehow no one ever seems to have done this. Can anyone help out?
Is there a way to have the tree nodes in a TreeView be LinkLabels?
