System.Web.UI.WebControls.TreeView shows hierarchical data in an expandable tree view with the possibility to have a checkbox next to each node. I want something similar, but I need to render a DropDownList at each node, so I can have more than two choices (checked or unchecked). Is there a way to do this with a TreeView? Or is there ...
Hello, I have a treeview control in WinForms that is filled from a wide variety of database content. I need to calculate the minimum width of the treeview control (after it is populated) so that horizontal scroll bars are not necessary to view the content. The calculation needs to account for the size of the longest text in the tree b...

Right, so I have to build a web app in asp.net 2.0 winforms. Id much much much prefer 3.5 MVC. because its cleaner, leaner, more modern and makes more sense to me. I know 3.5 MVC well, and have come from a Rails background, so this webforms stuff looks kinda gross to me :P. Anyway, I need an AJAX-backed tree control, one that loads the ...

I really like Visual Studio as an IDE, but there are a few things about it that really bug me. Namely, its class view. Not only is the class view tree structure cluttered, but it's not synchronized to the code view. I know there's a way of manually synchronizing them, but can't this be automated like it is in Netbeans? ...
I am accustomed to winform TreeView having a Sorted property which automatically manages nodes sorting. I now have to alphabetically sort an ASP.NET TreeView and I'm surprised I cannot find any similar property or callback method. Is there any way to automatically achieve this operation in ASP.NET or do I have to manually sort and inser...

Hence the user is asked to click a button to make this visible :) But the issue here is that when that treeview ( located within a element ) is made visible it MOVES the other elements down but i would prefer if it OVERLAYS ( something like what happens when we c...
I'm looking for the easiest solution to implement a folder browse dialog with checkboxes in front of the directories in my (C#) WinForms project. I saw this kind of dialog in Vista in the backup center. It was just like a normal Folder browse dialog, but in front of every folder there was a checkbox. If you checked a folder, all folders...

In WPF, when I right-click on a treeview item I would like it to be Selected/Activated before showing the context menu. This sounds pretty simple, but the inclusion of a hierachicalDataTemplate complicates things a little. I have the following treeview: <TreeView x:Name="trv" ContextMenu="{StaticResource conte...
This is a System.Windows.Forms.TreeView, not a WPF or Web TreeView. I must be missing something, because I can't believe this is that difficult. I've got a TreeView on my form. Loading all the data to populate the TreeView is very slow, so I want to load just the top-level nodes and then fill in the children as the user expands nodes. ...
The TreeView in Windows Forms always seems to want a node selected when it regains focus. If I have no nodes selected, and that treeview gains focus, I'll get an AfterSelect event with the first node selected, even though I didn't select it using the keyboard, mouse, or programmatically. The only workaround I can find is to check if th...
Any practical tips/tricks on how to do that? It doesn't seem that there is a lot of information about how to do that. I am loading data from the database into TreeView and the max number of nodes will be around 100. I am still interested in minimizing the ViewState. I will also be adding and deleting nodes dynamically (though the user...
