Create LookUp using X++ in Ax 2009

Hi Friends,

 Today we are going to create look up using code
1. Create a Form
2.Add a string Edit Control
3.In the methods of control write the following code

public void lookup()

{
//super();


// Declaration
Query   LookupQuery    =   new Query();

QueryBuildDataSource     LookupQueryBuildDataSource;

QueryBuildRange                  LookupQueryBuildRange;
SysTableLookup CustomSysTableLookup =       SysTableLookup::newParameters(tableNum(CustTable), this);

;

// Add fields that you want in Lookups

CustomSysTableLookup.addLookupField(fieldNum(CustTable, AccountNum));

CustomSysTableLookup.addLookupField(fieldNum(CustTable,Name));

LookupQueryBuildDataSource =

LookupQuery.addDataSource(tableNum(CustTable));

LookupQueryBuildRange=

LookupQueryBuildDataSource.addRange(fieldNum(CustTable,AccountNum));

//LookupQueryBuildRange.value(queryValue(NOYESCOMBO::Yes));

// Execute the Query

CustomSysTableLookup.parmQuery(LookupQuery);

CustomSysTableLookup.performFormLookup();

}
