In the column D, the user will select a value from a list (which is a dropdown which contains a data in a list). If the user select the value as "Click" in D1 then the cell E1 should be disabled. and If the user selects the value as "Clear" then the cell E1 and F1 should be disabled.

So that each values in the list has some conditions.

And also the disabled field should be blurred so that the user should understand this cell is disabled and he cannot enter any values in it.

Thanks in Advance..
