How to use ItemType if AutomationId is not given in white automation framework?

See more: (untagged)

This is first time i am trying to do the automation using white framework for WPF application.

I am trying to automate but facing issue related to the ItemType.

Development side they have given only ItemType as unique id for every controls. But it's very difficult to use and automate the application.
I am using the below namespace:

using System.Diagnostics;
using TestStack.White.Factory;
using TestStack.White.UIItems.Finders;
using TestStack.White.InputDevices;
using System.Threading;
using TestStack.White;
using TestStack.White.UIItems.WindowItems;
using System.Windows.Automation;
using TestStack.White.AutomationElementSearch;
using TestStack.White.UIItems.Custom;
using TestStack.White.UIItems.WindowStripControls;

When i am trying to get the ItemType for any controls then it is not appearing in the SearchCriteria.

I request any one to provide the solutions.

Thanks,
Vivek
