Creating columns in listView and add items using C#

Creating columns in listView and add items using C#

In C#, you can use the ListView control to display a list of items in a columnar format. Here's an example of how to create columns in a ListView control and add items to it:

// Create a new ListView control
ListView listView = new ListView();
listView.Dock = DockStyle.Fill;

// Create columns for the ListView control
listView.Columns.Add("Name", 120);
listView.Columns.Add("Age", 50);
listView.Columns.Add("Address", 200);

// Add items to the ListView control
string[] item1 = { "John", "30", "123 Main St." };
string[] item2 = { "Mary", "25", "456 Elm St." };
string[] item3 = { "Bob", "40", "789 Oak St." };
listView.Items.Add(new ListViewItem(item1));
listView.Items.Add(new ListViewItem(item2));
listView.Items.Add(new ListViewItem(item3));

// Add the ListView control to a form or container
this.Controls.Add(listView);

In this example, the ListView control is created and docked to fill its container. The Columns property is used to add three columns to the ListView control, with the specified column header text and width. The Items property is used to add three items to the ListView control, each represented by a ListViewItem object that contains an array of strings representing the item's subitems.

Note that you can also add items to the ListView control by creating ListViewItem objects directly:

ListViewItem item1 = new ListViewItem(new[] { "John", "30", "123 Main St." });
ListViewItem item2 = new ListViewItem(new[] { "Mary", "25", "456 Elm St." });
ListViewItem item3 = new ListViewItem(new[] { "Bob", "40", "789 Oak St." });
listView.Items.Add(item1);
listView.Items.Add(item2);
listView.Items.Add(item3);

In this example, ListViewItem objects are created directly and added to the Items property of the ListView control.

Note that you can also use data binding to populate a ListView control from a data source, such as a database or an array of objects. To do this, you can set the ListView control's DataSource property to the data source, and set the DisplayMember property to the name of the property or column that should be displayed in the control.
