Visual Basic 6 (VB6) is a popular programming language that allows you to create graphical user interfaces (GUIs) for Windows applications. One of the common controls that you can use in VB6 is the listview, which displays a list of items with subitems in a grid-like layout. You can use the listview to show data from a database, a file, or an array.
However, sometimes you may want to edit the values of the items or subitems in the listview, either by the user or by the code. For example, you may want to allow the user to change the price or quantity of a product in a listview that shows the inventory of a store. Or you may want to update the status or progress of a task in a listview that shows the tasks of a project.
In this article, we will show you how to edit listview subitem in VB6 for free, using some simple code and techniques. We will assume that you already have a basic knowledge of VB6 and how to use the listview control.
Steps to Edit Listview Subitem in VB6
To edit listview subitem in VB6, you need to follow these steps:
Create a listview control on your form and set its properties. For example, you can set its View property to lvwReport to display it in details mode, its FullRowSelect property to True to select the whole row when clicking on an item, and its GridLines property to True to show grid lines between items and subitems.
Add some columns and items to your listview using the Columns and ListItems collections. For example, you can add three columns: Name, Price, and Quantity; and some items: Apple, Banana, Orange, etc.
Create a textbox control on your form and set its properties. For example, you can set its Visible property to False to hide it initially, and its MultiLine property to False to make it a single-line textbox.
Add some code to handle the DblClick event of the listview. This event occurs when the user double-clicks on an item or subitem in the listview. In this event handler, you need to do the following:
Get the selected item and subitem index using the SelectedItem and SubItemHitTest methods of the listview.
Get the value of the subitem using the SubItems collection of the selected item.
Set the text, location, and size of the textbox to match the value, position, and width of the subitem.
Show the textbox and set its focus using the Visible and SetFocus methods.
Add some code to handle the LostFocus event of the textbox. This event occurs when the textbox loses focus, either by clicking on another control or pressing a key. In this event handler, you need to do the following:
Get the text of the textbox using its Text property.
Set the value of the subitem using the SubItems collection of the selected item.
Hide the textbox using its Visible property.
