UI Builder class in Dynamic AX

UI Builder class 

Today i will share how to give a filter lookup using an UI Builder class.                                                                                            

Step1 : First create a DP class for a customer report

[
    SRSReportQueryAttribute(queryStr(BSCustTable)),
    SRSReportParameterAttribute(classStr(SRCustomLookUpContract))

]
class SRCustomLookupDP extends SRSReportDataProviderBase
{
    SRCustomLookUpContract contract;
    CustNameTmp        CustNameTmp;
    AccountNum         AccountNum;
    CustGroupId       CustGroupId;

}

private Query buildQuery(

    Query                   _query,

    AccountNum                _AccountNum

    )

    {

    if(_AccountNum)

        _query.dataSourceTable(tablenum(CustTable), 1).addRange(fieldnum(CustTable, AccountNum)).value(queryvalue(_AccountNum));

        return _query;

     }

[

    SRSReportDataSetAttribute('CustNameTmp')

]

public CustNameTmp getCustNameTmp()

{

    select * from CustNameTmp;

    return CustNameTmp;

}

private void getReportParameters()

{

    SRCustomLookUpContract SRCustomLookUpContract = this.parmDataContract();

    if (SRCustomLookUpContract)

    {

        AccountNum    = SRCustomLookUpContract.parmAccountNum();

        CustGroupId  = SRCustomLookUpContract.parmCustGroup();

        //AccountNum    = SRCustomLookUpContract.parmAccountNum2();

    }

 }

public  void insertCustNameTmp(AccountNum _accountNum)

{

    CustTable  CustTable;

    ;

    while select CustTable where CustTable.AccountNum == _accountNum

    {

       CustNameTmp.AccountNum = _accountNum;

       CustNameTmp.Name     = CustTable.name();

       CustNameTmp.insert();

    }

}

/// <summary>

/// executes the logic based on the parameter entries

/// </summary>

/// <remarks>

/// fills up the temp table

/// </remarks>

[SysEntryPointAttribute]

public void processReport()

{

    Query query;

    QueryRun queryRun;

    CustTable       custTable;

    ;

    this.getReportParameters();

    queryRun = new QueryRun(this.buildQuery(this.parmQuery(),AccountNum));

    while(queryRun.next())

    {

        custTable = queryRun.get(tableNum(custTable));

        this.insertCustNameTmp(custTable.AccountNum);

    }

}

Step2 : Second create a Contract class for a customer report

[DataContractAttribute,

SysOperationContractProcessingAttribute(classstr(SRCustomLookupsUIBuilder))

]

class SRCustomLookUpContract

{

    AccountNum        accountNum;

    CustGroupId      CustGroupId;

}

[DataMemberAttribute('AccountNum')

    ]

public AccountNum parmAccountNum(AccountNum _accountNum = accountNum)

{

    accountNum = _accountNum;

    return accountNum;

}

[DataMemberAttribute('CustGroup')

    ]

public CustGroupId parmCustGroup(CustGroupId _CustGroupId = CustGroupId)

{

    CustGroupId = _CustGroupId;

    return CustGroupId;

}

Step3 : Third create a UI Builder class for a customer report

class SRCustomLookupsUIBuilder extends SrsReportDataContractUIBuilder

{

      DialogField   dialogAccountNum,dialogCustGroup; //dialogCreditRating;

      DialogGroup   dialogGroup, dialogGroup2;

      boolean       enable;

}

private void accountNumLookup(FormStringControl accountNumLookup)

{

    Query                   query = new Query();

    QueryBuildDataSource    qbds_CustTable;

    SysTableLookup          sysTableLookup;

    QueryBuildRange         qbr;

    if (accountNumLookup != null)

    {

        // Create an instance of SysTableLookup with

        // the current calling form control.

        sysTableLookup = SysTableLookup::newParameters(tablenum(CustTable), accountNumLookup);

        //sysTableLookup.addLookupMethod(

        // Add fields to be shown in the lookup form.

        qbds_CustTable = query.addDataSource(tableNum(CustTable));

         sysTableLookup.addLookupfield(fieldnum(CustTable, CustGroup),true);

        sysTableLookup.addLookupfield(fieldnum(CustTable, AccountNum), false);

        qbr = qbds_CustTable.addRange(fieldNum(CustTable,CustGroup));

        qbr.value("");

        sysTableLookup.parmUseLookupValue(false);

        sysTableLookup.parmQuery(query);

        // Perform the lookup.

        sysTableLookup.performFormLookup();

    }

}

/// <summary>

///    Builds the dialog.

/// </summary>

/// <remarks>

///    The dialog appears with the parameters.

/// </remarks>

public void build()

{

    SRCustomLookUpContract rdpContract =  this.dataContractObject();

    dialogAccountNum = this.addDialogField(methodstr(SRCustomLookUpContract,parmAccountNum),rdpContract);

    dialogAccountNum.lookupButton(3);

    dialogCustGroup = this.addDialogField(methodstr(SRCustomLookUpContract,parmCustGroup),rdpContract);

    dialogAccountNum.lookupButton(2);

}

private void CustGroupLookup(FormStringControl CustGroupLookup)

{

    Query                   query = new Query();

    QueryBuildDataSource    qbds_CustTable;

    SysTableLookup          sysTableLook;

    QueryBuildRange         qbr;

    CustTable               CustTable;

    if (CustGroupLookup != null)

    {

        // Create an instance of SysTableLookup with

        // the current calling form control.

        sysTableLook = SysTableLookup::newParameters(tablenum(CustTable), CustGroupLookup);

        //sysTableLookup.addLookupMethod(

        // Add fields to be shown in the lookup form.

        qbds_CustTable = query.addDataSource(tableNum(CustTable));

        sysTableLook.addLookupfield(fieldnum(CustTable, CustGroup),false);

         sysTableLook.addLookupfield(fieldnum(CustTable, AccountNum), true);

        qbr = qbds_CustTable.addRange(fieldNum(CustTable,CustGroup));

        qbr.value(dialogAccountNum.value());

        sysTableLook.parmUseLookupValue(false);

        sysTableLook.parmQuery(query);

        // Perform the lookup.

        sysTableLook.performFormLookup();

    }

}

public boolean customerAccModified(FormStringControl _control)

{

    dialogAccountNum.value(_control.valueStr());

    return true;

}

public void postRun()

{

    Dialog dialogLocal = this.dialog();

    DialogField dialogField, dialogField1;

    super();

    // This method should be called in order to handle events on dialogs.

    dialogLocal.dialogForm().formRun().controlMethodOverload(false);

    // Override the methods of department  field.

    dialogField1 = this.bindInfo().getDialogField(this.dataContractObject(), methodstr(SRCustomLookUpContract, parmCustGroup));

    dialogField1.registerOverrideMethod(methodstr(FormStringControl, lookup), methodstr(SRCustomLookupsUIBuilder,CustGroupLookup), this);

    dialogField = this.bindInfo().getDialogField(this.dataContractObject(), methodstr(SRCustomLookUpContract, parmAccountNum));

    dialogField.registerOverrideMethod(methodstr(FormStringControl, lookup), methodstr(SRCustomLookupsUIBuilder,accountNumLookup), this);

}
