    <Items>

        <ej:ListViewItems Text="Abstract"></ej:ListViewItems>
        <ej:ListViewItems Text="2 Acrylic Mediums"></ej:ListViewItems>
        <ej:ListViewItems Text="Creative Acrylic"></ej:ListViewItems>
        <ej:ListViewItems Text="Modern Painting"></ej:ListViewItems>

PreventSelection

When selecting a specific list item, it is highlighted with an active color. PreventSelection property is used to prevent this behavior by setting it to “true”.

NOTE

When the click or select action is completed, the highlight is undone automatically even when the property is set to “false”.

Refer the following code examples.

HTML

<ej:ListView ID="ListView1" runat="server" Height="450" Width="400" PreventSelection="true">

        <Items>
            <ej:ListViewItems Text="Artwork"></ej:ListViewItems>
            <ej:ListViewItems Text="Abstract"></ej:ListViewItems>
            <ej:ListViewItems Text="2 Acrylic Mediums"></ej:ListViewItems>
            <ej:ListViewItems Text="Creative Acrylic"></ej:ListViewItems>
            <ej:ListViewItems Text="Modern Painting"></ej:ListViewItems>
            <ej:ListViewItems Text="Canvas Art"></ej:ListViewItems>
            <ej:ListViewItems Text="Black white"></ej:ListViewItems>
            <ej:ListViewItems Text="Children"></ej:ListViewItems>
            <ej:ListViewItems Text="Preschool Crafts"></ej:ListViewItems>
            <ej:ListViewItems Text="School-age Crafts"></ej:ListViewItems>
        </Items>
</ej:ListView>

PersistSelection

PersistSelection property is used to highlight the selected item in the ListView control even after touch end happens. By default, the active state is removed once the touch end happens.

Refer the following code examples.

HTML

<ej:ListView ID="ListView1" runat="server" Height="450" Width="400" PreventSelection="true">
        <Items>
            <ej:ListViewItems Text="Artwork"></ej:ListViewItems>
            <ej:ListViewItems Text="Abstract"></ej:ListViewItems>
            <ej:ListViewItems Text="2 Acrylic Mediums"></ej:ListViewItems>
            <ej:ListViewItems Text="Creative Acrylic"></ej:ListViewItems>
            <ej:ListViewItems Text="Modern Painting"></ej:ListViewItems>
            <ej:ListViewItems Text="Canvas Art"></ej:ListViewItems>
