Example

WebForms:

ASPX

<dx:ASPxListBox ID="ASPxListBox1" runat="server" Theme="Office365" ClientInstanceName="listBox">
    <Items>
        <dx:ListEditItem Text="Item1" Value="10" />
        <dx:ListEditItem Text="Item2" Value="20" />
        <dx:ListEditItem Text="Item3" Value="30" />
    </Items>
</dx:ASPxListBox>
<br />
<dx:ASPxButton ID="ASPxButton1" runat="server" AutoPostBack="False" Text="Get Item's Info" Theme="Office365">
    <ClientSideEvents Click="function(s, e) {
        var item = listBox.GetSelectedItem();
        memo.SetText('Text: ' + item.text + '\n' + 'Value: ' + item.value + '\n' + 'Selected: ' + item.selected + '\n' + 'Index: ' + item.index );  
    }" />
</dx:ASPxButton>
<br /><br />
<dx:ASPxMemo ClientInstanceName="memo" ID="ASPxMemo1" runat="server" Height="71px" Width="170px"></dx:ASPxMemo>

MVC:

C#

@Html.DevExpress().ListBox(settings => {
    settings.Name = "listBox";
    settings.Properties.Items.Add("Item1", 10);
    settings.Properties.Items.Add("Item2", 20);
    settings.Properties.Items.Add("Item3", 30);
}).GetHtml()
<br />
@Html.DevExpress().Button(settings => {
    settings.Name = "button";
    settings.Text = "Get Item's Info";
    settings.ClientSideEvents.Click = "OnClick";
}).GetHtml()
<br /><br />
@Html.DevExpress().Memo(settings => {
    settings.Name = "memo";
    settings.Height = 90;
}).GetHtml()

JS

function OnClick(s, e) {
  var item = listBox.GetSelectedItem();
  memo.SetText('Text: ' + item.text + '\n' + 'Value: ' + item.value + '\n' + 'Selected: ' + item.selected + '\n' + 'Index: ' + item.index);
}

Example

The code sample below demonstrates how you can use the ASPxTrackBar control to display the wavelength range of the selected color.

The ASPxClientListEdit.SelectedIndexChanged event is handled to specify the track bar range interval. The ASPxClientTrackBar.SetPositionStart and ASPxClientTrackBar.SetPositionEnd methods specify range limits.

The image below shows the result.

JS

function setWavelength() {
     tbWavelength.SetPositionStart(colorList.GetValue());
     if (colorList.GetSelectedIndex() == 0) tbWavelength.SetPositionEnd(750)
     else tbWavelength.SetPositionEnd(colorList.GetItem(colorList.GetSelectedIndex() - 1).value); 
     label.SetText('The visible ' + colorList.GetSelectedItem().text + ' light has a wavelength in the interval ' 
     + tbWavelength.GetPositionStart() + ' to ' + tbWavelength.GetPositionEnd() + ' nm');
}
