validation rule on dropdown control

[ganesh_lathi]

I need to apply a validation rule on dropdown control. is there any easy way to use Nintex "Rules" ?

Condition i need to check is - fire the validation if the value of dropdown  = "Please select value...",

yes, that's exactly what rules are designed for.

'Please select value...' means there is no item/option selected from a dropdown list, so you can test it for emptiness like

isNullOrEmpty(dropdown)
