UI Builder class in Dynamic AX

http://vasantharivali.wordpress.com/ - Filter second lookup based on first value

UI Builder class

Step1 : Your Class must extends SrsReportDataContractUIBuilder

class SimpleDemoUIBuilder extends SrsReportDataContractUIBuilder
{
DialogField dialogEmplId;
DialogField dialogName;
boolean enable;
SimpleDemoContract contract;

}// two fields emplId and Name will reflect in the lookup in dialog form at the time of report opening.

Step2 : Override the build method

public void build()
{
contract = this.dataContractObject();
dialogEmplId = this.addDialogField(methodStr(SimpleDemoContract, parmEmplId),contract);

}// this method used for adding the field  which is from contract class.

Step3 : Write this below code to get lookup

private void emplIdLookup(FormStringControl emplIdlookup)
{
Query query = new Query();
QueryBuildDataSource qbds_EmplTable;
SysTableLookup sysTableLookup;

// Create an instance of SysTableLookup with the current calling form control.
sysTableLookup = SysTableLookup::newParameters(tableNum(FilterDemo), emplIdlookup);
// Add fields to be shown in the lookup form.
sysTableLookup.addLookupfield(fieldNum(FilterDemo,EmplId));
sysTableLookup.addLookupfield(fieldNum(FilterDemo,Name));
qbds_EmplTable = query.addDataSource(tableNum(FilterDemo));
sysTableLookup.parmQuery(query);
// Perform the lookup
sysTableLookup.performFormLookup();
}

Step4 : Override this method

public void getFromDialog()
{
contract = this.dataContractObject();
super();
}

Step5 : Override this method

public void initializeFields()
{
contract = this.dataContractObject();
}

Step6 : Override this method

public void postBuild()
{
super();
dialogEmplId = this.bindInfo().getDialogField(this.dataContractObject(),methodStr(SimpleDemoContract,parmEmplId));dialogEmplId.registerOverrideMethod(methodStr(FormStringControl, lookup),
methodStr(SimpleDemoUIBuilder,emplIdLookup), this);dialogEmplId.lookupButton(2);
}
