Workaround:Using the following line of code:node.StyleAttributes.Add("background-color", "Aqua"); allows the background color of the node to be set. But this property works slightly differently than the BackColor property. BackColor property in 9.2 highlights only that specific node while using the StyleAttributes in 9.3, highlights the node as well as its children. It seems to highlight the entire div or table row that the particular node is within. A screenshot showing this behavior has been attached.
