I want to show large image in tree node and create border for node.
So I think, I need to create treeview custom node, am I right?
Please give me advice how to do, create custom node and do other things?
In order to show nodes with bigger images, simply set the desired image to Image property of the desired node and then set the AutoSizeItems property of the TreeViewElement to true, so the nodes will be sized according to their content.
In order to show borders around the nodes, set the top and bottom border colors of the NodeElement in the NodeFormatting event handler.
Attached you can find a sample project with the desired functionalities implemented.
Let me know if you have any other questions.
