Hi Bharath,

I think this can be solution:
You can use a validation rule on the picklist (IF check box=true THEN no change allowed)

Kind Regards

So first of all, are you talking about Standard Detail Page or Visualforce Page.
1. Visualforce Page:- You can simply use Javascript, using 'onchange' event you can disable the picklist field.
2. Standard Page:- There can be 2 ways:-
    a. Write a validation rule formula as 'checkbox_field = true && ISCHANGED(picklist_field) '. In this case, visibly the picklist field won't be locked.
    b. Create one more Record Type and one more Page layout (keeping the picklist field as read only) and assign the Page layout to the Record Type. Write a workflow which will update the record type when the check box will be checked.
    First solution is preferable.
