TreeView CheckBoxes, but not their children.

[Justin]

I'm writing an app in C# .net 2.0. I want to have a TreeView where the first
level of nodes would have check boxes, but their subsequent children would
not have check boxes.

Is this achievable using the .net controls? If not, how can I make this
possible?

Thanks,
Justin

Hi Justin,

Thanks for your post.

Normally, there is no build-in support for this in .Net, however, we can
p/invoke Win32 SendMessage API to send TVM_SETITEM message to the treeview
control to turn off certain node's checkbox. For more information, please
refer to my original reply in the link below:

Thank you!

This is a hack, but it works.

Why would the ASP.net treeview control allow for checkboxes at the node
level (node.ShowCheckBox) but the VB .net treeview does not? Seems to
me like the controls should all be consistent. Is there any chance
this has been changed in a Service Pack for Visual Studio? I sure could
use it.
