How to throw alert message to user if the field is blank in qlikview

[saivina2920]

I have some data is blank. If the data is blank for the particular criteria, then it should throw alert message to user, "this filed has some blank"

example has shown below.

when user select EMP_STATE, then if find any blank available in the EMP_RELIEVE_DATE then, it should throw alert message to user "EMP_RELIEVE_DATE has some blank values"

below is my expressions. but, alert not showing...?

=if(IsNull(EMP_RELIEVE_DATE) AND [EMP_STATE]='$(vEmPlaces)','Contains Blank','Not blank')

Thanks for all your help.

We were working java script at many applications. we addict for that.

that's why we are expecting the same.

Anyhow we can show to user at least this text object concept.

One last question, Is it possible to hide the textbox till user selects the dropdown by default...?

otherwise i accept your solution. Thanks once again..

you are saying not to show the text box unless there is at least one selection?  you can add that to the condition:

=GetSelectedCount(EMP_STATE)>0 and Count(EMP_STATE)>Count(EMP_RELIEVE_DATE)

Yes. Awesome.
