Windows. Forms. listview Control

Note the following issues that may cause errors, which can be clarified and understood:
1. the columns of listview must be generated in advance (either during design or in ProgramMedium)
2. listviewitem. text is displayed as the text in the first column. When using the design view, its subitems set contains subitems [0], that is, the text in the first column, you must ensure that only columns other than this can be entered correctly.
3. To avoid confusion, you can generate a listviewitem and its subitems set in this way:
Listviewitem listview. Items. Add (New listviewitem (string [] items); // return the listviewitem object
4. You can use listviewitem. subitems to obtain the text values of all its columns.
