private void
  createdispalyoption() 
{ 
        FormBuild           formBuild = new
  FormBuild(formStr(ProdTableListPage), true); 
        FormBuildDataSource fbds =
  formBuild.form().dataSource(1); 
        TreeNode            treeNode; 
        #AOT 
       
  formBuild.addMethod("displayOptions", "public void
  displayOption(ProdTable  _prodTable,
  FormRowDisplayOption _options){ ProdTableListPageSalesRelTmp    _prodTableListPageSalesRelTmp;select
  EarliestShipDateRequested from _prodTableListPageSalesRelTmp where
  _prodTableListPageSalesRelTmp.ProdId 
  ==  _prodTable.ProdId
  && 
  _prodTableListPageSalesRelTmp.SessionId ==  sessionId();
  if(_prodTable.DlvDate>_prodTableListPageSalesRelTmp.EarliestShipDateRequested
  && _prodTableListPageSalesRelTmp.EarliestShipDateRequested
  &&  _prodTable.DlvDate){
  _options.backColor(8421631);_options.affectedElementsByControl(ProdTable_DlvDate.id());}
  super(_prodTable, _options);}", treeNode); 
        formBuild.form().save();

Add below code to
  the below method 
public void
  initializing() 
{ 
    TreeNode            treeNode; 
    #AOT 
    if(!treeNode) 
    this.createdispalyoption(); 
}

Go to the field in Grid for which color should be applied. Make it Auto declaration  to Yes. In my case "
ProdTable_DlvDate".
