I've used the following js code to expand/collapse all nodes of an ASP.Net TreeView control: // handle tree - this doesn't seem to work when the tree contains node images function TreeviewExpandCollapseAll(treeViewId, expandAll) { var displayState = (expandAll == true ?

Here is my situation: I will have a web page with TreeView control, which is supposed to be expadable/collapsable/editable. All good so far. I know that postback is used heavily in this control which brings me to another problem that's specific to our production set-up. We have 2 web servers here and a load balancer, the load balancer ...
I am using a Windows Forms TreeView control in my program. I would like to allow the user to select multiple nodes at the same level by dragging their mouse pointer around (also called a "lasso" selection). I don't think a standard TreeView allows that. My question is what would be the best way to achieve this? Do I have to write custom...

The System.Web.UI.WebControls.TreeView class offers this event, but the Forms version of TreeView doesn't. What's the equivalent in the Forms world? I'm using AfterSelect but it doesn't seem quite right. Maybe it is in fact what I'm looking for but the documentation is a bit hazy. ...
I need a tree that I can add nodes to, and save to the database once all the desired nodes have been added. I have looked into TreeView server side control, but I wanted to check out the Jquery tree as well. I realize that I will have to use JSON web services to write the data to the database (or retrieve it). I am new to Jquery. Can so...
I have a following scenario: an asp.net TreeView control, where the user can add/delete nodes. To add a node they would click on the desired node in the tree, a pop-up window will be presented, where the user will enter info, this pop-up will need to save some data in the database (but not the tree data, just node data - nodes can exist ...
I would like to databind my TreeView from a data structure. After googling some, I came to a conclusion that writing my own simple Tree structure using List of Nodes would be the thing to do. However, I would like to know whether I am on the right path and not overdoing it - from what I know there is no Tree structure in c#. What are ...
