Moreover no need to write select statement.

you can directly refer fields such as CurrentDataSourceName.FieldName

e.g. in your case

if(ITTI_EmpDetailsDS.PassPort == NoYes::Yes)

{

// set object mandatory

}

else

{

//let it be non mandatory

}

Hi, can I suggest that this type of related field rule is normally validated on writing of the record rather than by making a datasource field mandatory. Perhaps write your checking in your Datasource's "ValidateWrite" method.

As an example if these fields are in a grid you will get strange results. As soon as you check the checkbox the "PassportNum" field will show as mandatory on everysingle record.

then write your code as suggested by Jonathan, on validateWrite(). it must validate before save.

above code can help you at user interface level. logic would be same in validateWrite as well, only difference will be that you will refer objects by this keyword e.g. this.FieldName ; throwing back checkFailed in case of non-valid data.

As Jonathan Halland said try to write code in Datasource's "ValidateWrite" method.

Certainly it works.

Have a try and let us know.

we are talking about Table Method validateWrite(), for sure you cannot refer fields by this keyword on form level, if you will read my previous reply you will find. kindly write your code on table level and use checkfailed to return false in case mandatory information is not provided
