Hi!

How do I hide checkbox for the childnodesof a treeview control? There is no property for the TreeNode to disable the checkbox once TreeView.CheckBoxes is set to true.

Hi,

There is no build-in support, you have to p/invoke Win32 API to send TVM_SETITEM with TVIS_STATEIMAGEMASK flag. Seethis sample code below by Jeffery:

Hi!

But, I want the checkbox available for rootnodes. I have a 2 Level Treeview. The Level1 Nodes should have the Checkbox. If you were also referring for the same can you guide me in applying empty icon for the childnodes?

Hi,

I have same requirement.

Adding empty icon will display ICON, it is not hiding checkbox.

Is there any way I can hide checkbox for any particular node?

thanks

Sweet! Gavin, thanks for finding that. That approach is much better than owner-drawing the whole thing to hidecheckboxes.

Just a tip for someone who will use Jeffrey Tan solution:

The checkbox is showing again when TreeNode check box is checked (by pressing space when TreeNode has focus, for example).
