Workaround
Here are two solutions:A) Listen for the Toc_NodeExpanded event and insert the following lines of code. protected void Toc1_NodeExpanded(object sender, TreeViewPlusNodeEventArgs args) { if (Toc1.CallbackResults.Count < 1 && Toc1.RenderOnDemand) { args.Node.Refresh(); } }The current situation is that the TOC node is unresponsive after the user has been clicking the +/- while the map request is processing. With this code, the node can be expanded successfully once the map request finishes.B) Another option is to set RenderOnDemand = False on the TOC control. This causes the TOC swatches and nodes to be pre-cached so that clicking the + does not need to request the information. Depending on the complexity of the Map, this may result in the application startup being slightly slower.Steps to Reproduce
