Hi I am new to excel for this kinds requirements.
I want to freeze the cell content (from a drop down) once a selection is made. Users should not be able to modify the entered content. Once the selection is made from data validation list then user can not change it. Ex. If we have "M" and "F" in drop down(Data validation). Once user select "M" then he will not allow to change this with other option.
Let me know if you need more clarification. Direct me to the answer if question is already there.
