ListView Control in VB.net – Properties, Methods and Events

What is ListView Control in VB.net?

The ListView Control in VB.net is used to show a group of items in Windows Forms.

It uses one of the view lists, like LargeIcon, SmallIcon, Details, List, or Tile.

The ListView in VB.net also lets the user add or take away icons from the ListView Control.

Let’s create a ListView in VB.net by dragging a ListView Control from the Toolbox and dropping it on the form.

ListView shows a list of items with icons next to them. You can add and remove items from a ListView control by using its Item property.

The SelectedItem property has a list of the items that have been chosen.

You can choose more than one item in the list view by using the MultiSelect property.

You can put check boxes next to the items with the CheckBoxes property.

        ListView1.View = View.Details  ' Display the List in details  
        ListView1.GridLines = True   ' Set the Grid lines   
        ListView1.Columns.Add("Student Name", 200, HorizontalAlignment.Left) ' set the name of column  
        ListView1.Columns.Add("Address", 300, HorizontalAlignment.Left) ' set the name of column  
        ListView1.Columns.Add("Email", 100, HorizontalAlignment.Left) ' set the name of column  
        ListView1.Columns.Add("Course", 100, HorizontalAlignment.Left) ' set the name of column  
        ListView1.BackColor = Color.LightSkyBlue
    End Sub

    Private Sub Label3_Click(sender As Object, e As EventArgs) Handles Label3.Click

    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim str(4) As String
        Dim itm As ListViewItem
        str(0) = TextBox1.Text  'Accept value from the user.  
        str(1) = TextBox2.Text
        str(2) = TextBox3.Text
        str(3) = TextBox4.Text
        itm = New ListViewItem(str)
        ListView1.Items.Add(itm) 'Add the items into the ListView  
    End Sub
End Class

Program Output:
