The Report Tree panel shows the hierarchy of the report, i.e. represents all the components of the report in the form of a tree. In addition, if an event handler is added to the component, it will also be displayed in the hierarchy of the report. The picture below shows an example of the Report Tree panel:
As can be seen on the picture above, hierarchy is represented on the principle of "nesting", and an event handler is added for the GetValue event of the Text10 component. The Report Tree panel provides the ability to visually identify the submission of a "component to a component".
