Hello, i made an on implemenation of the checkbox with more states. now i want to use that control in the treeview instead of the normal checkbox; can someone help me a bit how to do that?

Hello Dave,

Thanks for your post on MSDN forum.

Based on my understanding, if the CheckBoxes property is set to true, TreeView control will show a "CheckBox" in front of each TreeNode to let user check or uncheck the node, however, the "CheckBox" in front of each TreeNode is not a real CheckBox control, it is painted like a CheckBox. If you just want to show more states for TreeNode, I suggest that you customize the appearance of the TreeView control by setting the DrawMode property and handling the DrawNode event.

Check the following for a sample.

If you want to embed the control in a TreeNode, I suggest that you place the control on the TreeNode when that node is selected, here is a sample for your reference.
