Hello Myat Su,
Thank you for writing.
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
, 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
Attached you can find a sample project with the desired functionalities implemented.
Let me know if you have any other questions.
