<dx:ASPxButton ID="ASPxButton1" runat="server" AutoPostBack="False" GroupName="G" Text="Disable Button">
<ClientSideEvents CheckedChanged="onCheckedChanged" />

</dx:ASPxButton>
The ClientInstanceName property is important when a control is contained within a naming container, for instance, within an ASPxPageControl‘s page or an ASPxPopupControl‘s window.
If the ClientInstanceName property is not specified for a control, the control’s client identifier is generated automatically and equals the value of the control’s ID property. Note that in this case, client-side programmatic access to the control is not allowed when the control is contained within a naming container.
