I just showed an example. You have to use the Object Spy tool. Not all control properties are the same.

Use the Object Spy tool to have a look at the properties of your control. The appropriate property value will be either true or false, this will usually indicate whether the control is editable.

For example,

You can then perform a check point, to test the property value.

Shivani3, while adding the property checkpoint you can look for these three options. Also, it depends on how your application was coded. Look into the source code of that object and find if the class has attribute as disabled.
