I have tree view located in master page. I have hierarchy up to 4th level

category 1
 - inner category 1
    -inner inner category 1
 - inner category 2
 - inner category 3

category 2

and so on...

On clicking category 1 its child node will be opened.

When I click on inner category 2 which link to some page, then that page is executed so tree get refreshed due to post back.

But I want to keep that node active, i.e with some distinguish color then other node.

Share the code for this:

You need to stop postback on click of the link. OR not get re-render keeping it in an update panel.

Keep your TreeView inside an UpdatePanel and also if you are creating the TreeView on Page_Load, keep it inside !IsPostBack check, this will prevent your tree from getting refreshed.

For coloring the selected node, you can use "TreeView1.SelectedNodeStyle.ForeColor", other styles can also be set using SelectedNodeStyle property of TreeView.

Hope it helps..
