How can I set the colour/style of specific nodes according to the value of a field in a datasource? For example, if I assign a datasourceid for the treeview which has a boolean/bit field then the nodes that have a value of true/1 should be bold.
I believe, you can perform this in NodeDataBound event. In the handler, check for the boolean value and access the node and set the Font.Bold property to True.
