I would like to hide/unhide nodes based on a bound data source item value. In my sample project, I can assign a full data source and a filtered data source from 'All Data Source' button click or 'Filtered Data Source' button click. But hide and unhide using the node visible property in radTreeView1_NodeFormatting event triggered from the 'Visible = Primary (Hide)' and 'All Visible Unhide' don't work. Also, the first click of 'Visible=Primary(Hide)' only formats the first 5 nodes. It seems once a node's visible property is false, you can not set it to true programmatically. I do not want to refresh or reload the tree view.
It would be really great if there was some way to filter tree view based on Tag versus Text property. Then I could simply populate the tag with true or false and filter.
