This example explains an easy way to edit ListView subitems. A double click on the ListView.SubItem will visualize a TextBox
overlaying the SubItem with same size. The entered signs will be written to the SubItem after TextBox_LostFocus event was raised
(by clicking on the ListView control or hit RETURN key).
The following Visual Basic code is to be inserted into a form (e.g. MainForm).
The Form contains a TextBox, Button and ListView control. TextBox and Button are hidden ([control].Visible = False)
For the listview the following settings apply:
- set ListView.FullRowSelect = True
- set ListView.GridLines = True
- set ListView.Details = True
Remark: The LostFocus will not be raised if you click on the form. It will be called when you click on another control such as the ListView.
