I have a virtual string tree component. In which I am creating some virtual node at run time. While loading the application I want to set the first item to be selected. Also I have another virtual string tree component in the same view. This I am using as a grid view. I am loading some data to the grid view according to the tree view selection. If the default item is selected then its corresponding data should be displayed in the grid view. I am using virtual tree view component from Softgems.
