DAX SamplesValidate Field Example: Public Boolean validateField(fielded _fieldIdToCheck){

Boolean ret;Ret = super(_fieldIdToCheck);If(_fieldIdToCheck == fieldNum(kkk_CustTable, CreditLimit){

If(this.CreditLimit > 2000.00){

Ret = ret && checkFailed(“Credit limit cannot be greater than 2000”);}

} Container Example:Container con = [“1000”, “xyz”, 40, 500.00];Container rcon;Int I;;Info(int2str(conlen(con));Info(conpeek(con,3));Conview(con);For(I =1; i<=conlen(con);i++){

Info(conpeek(con,i));}Rcon = condel(con,1,2);Conview(rcon);Con = connull();Conview(con);Info(strfmt(“xyz is found at %1”,confind(con,”xyz”))); Functions :

Conpoke - replace an elementConins – insert an elementConlen – find lengthConpeek – will get the value

Condel – deletes set of elements in container and return new containerConfind – will find an element in containerConnull – null the containerConview – show all the elements in container
