Refresh form datasource from Class

 Auto Refresh form after uploaded data 

in Class main method 

static client void main(Args   _args)

{

YourClassName          testclass;

FormDataSource     callerds; 

;

testclass = new  YourClassName();

if(_args && _args.record() && _args.record().isFormDataSource())

}

    testclass.run();

//Refresh form DS

callerds.research();

}

get selected record from Lookup

based on selected record from parent code lookup modify item id in purchase order.

create a new custom lookup form as shown below.

override closeselect   method :

Public void closeselect(str  _selectString)

{

FormRun      formrun;

Object          formrunobj;

     super(_selectString);

if(element.args() != null

    && element.args().caller() != null

        }

}

}

override init method :

set  Autodeclaration Yes Highlited control in 

Public void int()

        {

            formrun =  element.args().caller();

        }

    super();

    

}

call Lookup form in ParentCode control level in PurchTable form.

Public void lookup()

{

      Args       args = new Args();

     FormRun      lookupform;

    InventTable       inventTable;

    args.name(formstr(parentlookup));

    lookupform.wait();

    if(lookupform.closeOk())

    {

        inventTable = lookupform.docCursor();

    }

}

Get RecId from inventTable modify ItemId from modified method.

ComboBox filter

1. Add Enum control in Form

2 .Enum Contol AutoDeclaration property set to Yes. 

3 .in control modified method add below code.

public boolean modified()

{

     int                                ret;

    QueryBuildRange       range;

    ;

    ret = super();

    range = SysQuery::findOrCreateRange(
        purchTable_DS.query().dataSourceTable(tablenum(PurchTable)),
        fieldnum(PurchTable, PurchStatus));
    range.value(queryValue(controlname.selection()));
    purchTable_DS.executeQuery();

    return ret;

}

Some Important function

 Get Last Two Characters

Str     s = 'AXAPTA';

info(strfmt( subStr(s,strLen(s)-1,strlen(s)));

OutPut : TA

Get First Two Characters

OutPut : AX

Validate in UI Builder class

 Write below code in your UIBuilder Class

public boolean validatePostingProfile(FormStringControl  _control)

{

    boolean        ret = true;

   VendPostingProfile    vendPostingProfile;

    vendPostingProfile  = _control.valueStr();  

    if(VendLedger::find(vendPostingProfile))

    {

        if(vendPostingProfile != ' ' )

        {

        error ('Posting profile does not exist');

        ret = false;

    }

    return ret;

}

call the above method in PostBuild  method

dlgpostingProfile.registerOverrideMethod(methodStr(FormStringControl, validate), methodStr(<yourUIBuilderclass>, validatePostingProfile),this);
