ASPX

<dx:ASPxCheckBoxList ID="checkBoxList" runat="server">
    <Items>
        <dx:ListEditItem Value="1" />
        <dx:ListEditItem Value="2" />
        <!-- ... -->
    </Items>
</dx:ASPxCheckBoxList>
<dx:ASPxButton runat="server" ID="ClickButton" Text="Click" OnClick="ClickButton_Click" />

C#

protected void ClickButton_Click(object sender, EventArgs e)
{
    var selectedValues = checkBoxList.SelectedValues;
    var selectedItems = checkBoxList.SelectedItems;
    var selectedIndices = checkBoxList.SelectedIndices;
    // ...
}

VB.NET

Protected Sub ClickButton_Click(ByVal sender As Object, ByVal e As EventArgs)
    Dim selectedValues = checkBoxList.SelectedValues
    Dim selectedItems = checkBoxList.SelectedItems
    Dim selectedIndices = checkBoxList.SelectedIndices
End Sub

If the SelectedItems property returns null, make sure that you set the ValueType property to an .NET type that matches the ValueField column type. Otherwise, the editor cannot find the corresponding item because the editor’s ValueType property does not match the item type (String by default).
