Error while setting the Read-only Property for the Multi Select Control

Hello All,

We have an application which is migrated from Ext.Net 1.6 to Ext.Net 2.5.3. In the application some of the forms using the Multi-select control allowing the user to select multiple values. Part of the requirement in some scenarios we have to make that multi-select control as read-only. That means user can see the values in side the control, But shouldn't allow him to select any.

Here the issue is, We have read-only property to that control. But when we apply that property it gives me runtime error 'Object doesn't support property or method 'setReadOnly''. We tried other property selectable=false as well, But this property makes the control as disable instead of read-only. The control have more values to display, If it is disable the user can't browse the control to see more values.

I am looking forward to hear from the people who had this kind of issue and resolved. Appreciate if you provide any work around solution to full fill my requirement.

I am attaching screenshot here for error message.
