Фильтр поля с помощью значка молния

Такую реализацию можно посмотреть в BPMonline Sevice Desk 5.X, карточка инцидента BaseServiceRequestInBPMonlineEditPage, сервис фильтруется по сервисному договору.

Там, в частности используются функции.

Первая — получает список отфильтрованных по сервисному договору сервисов:

[csharp]
RecordData[] GetAvailableServicesNew(Guid serviceAgreementId){
if (serviceAgreementId == Guid.Empty) {
return null;
}
var resultList = new List();
var serviceIdsList = new List();

var entitySchemaManager = UserConnection.GetSchemaManager("EntitySchemaManager") as EntitySchemaManager;
//in packages
var serviceInServiceAgreementSchemaQuery = new EntitySchemaQuery(entitySchemaManager, "ServiceInServiceAgreement");
var serviceIdQueryColumnName = serviceInServiceAgreementSchemaQuery.AddColumn("Service.Id").Name;
var serviceNameQueryColumnName = serviceInServiceAgreementSchemaQuery.AddColumn("Service.ServiceName").Name;
var packageNameQueryColumnName = serviceInServiceAgreementSchemaQuery.AddColumn("ServicePackage.Name").Name;
var serviceAgreementFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "ServiceAgreement.Id", serviceAgreementId);
var typeFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "Type.Id", new Guid("f3b90f08-f46b-1410-809e-00155d852b12"));
var packageNotNullFilter = serviceInServiceAgreementSchemaQuery.CreateIsNotNullFilter("ServicePackage");
var activeFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "Service.Status.Active", true);
IEntitySchemaQueryFilterItem filter = null;
object[] serviceRequestTypeServiceIds = null;
if (string.IsNullOrEmpty(VirtualEntitySchemaName)) {
filter = new EntitySchemaQueryFilterCollection(serviceInServiceAgreementSchemaQuery, LogicalOperationStrict.And, serviceAgreementFilter, typeFilter, packageNotNullFilter, activeFilter);
}
else {
serviceRequestTypeServiceIds = GetServicesForServiceRequestTypeByServiceAgreement(serviceAgreementId);
IEntitySchemaQueryFilterItem serviceRequestTypeFilter;
if (serviceRequestTypeServiceIds.Length == 0 ) {
//HACK
serviceRequestTypeFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "Service.Id", Guid.NewGuid());
}
else {
serviceRequestTypeFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "Service.Id", serviceRequestTypeServiceIds);
}
filter = new EntitySchemaQueryFilterCollection(serviceInServiceAgreementSchemaQuery, LogicalOperationStrict.And, serviceAgreementFilter, typeFilter, packageNotNullFilter, activeFilter, serviceRequestTypeFilter);
}
serviceInServiceAgreementSchemaQuery.Filters.Add(filter);
var servicesInServiceAgreement = serviceInServiceAgreementSchemaQuery.GetEntityCollection(UserConnection);
foreach (var serviceInServiceAgreement in servicesInServiceAgreement) {
var serviceId = serviceInServiceAgreement.GetTypedColumnValue(serviceIdQueryColumnName);
if (!serviceIdsList.Contains(serviceId)) {
var serviceName = serviceInServiceAgreement.GetTypedColumnValue(serviceNameQueryColumnName);
var packageName = serviceInServiceAgreement.GetTypedColumnValue(packageNameQueryColumnName);
var recordData = new RecordData();
recordData.Id = serviceId;
recordData.Name = string.Concat(serviceName, " (", packageName, ")");
resultList.Add(recordData);
serviceIdsList.Add(serviceId);
}
}
//just services
serviceInServiceAgreementSchemaQuery = new EntitySchemaQuery(entitySchemaManager, "ServiceInServiceAgreement");
serviceIdQueryColumnName = serviceInServiceAgreementSchemaQuery.AddColumn("Service.Id").Name;
serviceNameQueryColumnName = serviceInServiceAgreementSchemaQuery.AddColumn("Service.ServiceName").Name;
serviceAgreementFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "ServiceAgreement.Id", serviceAgreementId);
typeFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "Type.Id", new Guid("f3b90f08-f46b-1410-809e-00155d852b12"));
var packageNullFilter = serviceInServiceAgreementSchemaQuery.CreateIsNullFilter("ServicePackage");
activeFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "Service.Status.Active", true);
filter = new EntitySchemaQueryFilterCollection(serviceInServiceAgreementSchemaQuery, LogicalOperationStrict.And, serviceAgreementFilter, typeFilter, packageNullFilter, activeFilter);
if (!string.IsNullOrEmpty(VirtualEntitySchemaName)) {
serviceRequestTypeServiceIds = GetServicesForServiceRequestTypeByServiceAgreement(serviceAgreementId);
IEntitySchemaQueryFilterItem serviceRequestTypeFilter;
if (serviceRequestTypeServiceIds.Length == 0) {
//HACK
serviceRequestTypeFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "Service.Id", Guid.NewGuid());
}
else {
serviceRequestTypeFilter = serviceInServiceAgreementSchemaQuery.CreateFilterWithParameters(FilterComparisonType.Equal, "Service.Id", serviceRequestTypeServiceIds);
}
filter = new EntitySchemaQueryFilterCollection(serviceInServiceAgreementSchemaQuery, LogicalOperationStrict.And, filter, serviceRequestTypeFilter);
}
serviceInServiceAgreementSchemaQuery.Filters.Add(filter);
servicesInServiceAgreement = serviceInServiceAgreementSchemaQuery.GetEntityCollection(UserConnection);
foreach (var serviceInServiceAgreement in servicesInServiceAgreement) {
var serviceId = serviceInServiceAgreement.GetTypedColumnValue(serviceIdQueryColumnName);
if (!serviceIdsList.Contains(serviceId)) {
var recordData = new RecordData();
recordData.Id = serviceId;
recordData.Name = serviceInServiceAgreement.GetTypedColumnValue(serviceNameQueryColumnName);
resultList.Add(recordData);
serviceIdsList.Add(serviceId);
}
}
return resultList.ToArray();
}
[/csharp]

Вторая — строит меню у кнопки:
[csharp]
void SetServiceToolButtonStateNew(LookupEdit serviceLookupEdit, ToolButton serviceLookupToolButton, RecordData[] availableServices){
CreateToolButtonMenuNew(serviceLookupEdit, serviceLookupToolButton, availableServices, "ShowAllServices", AllServicesInAgreementCaption.ToString(), false);
}

void CreateToolButtonMenuNew(LookupEdit lookupEdit, ToolButton toolButton, RecordData[] availableItems, string allItemsMessage, string allItemsCaption, bool showIfOneRecord) {
toolButton.Menu.Clear();
Page.AddScript(string.Format("{0}.getMenu().removeAll();", toolButton.ClientID));
if (availableItems == null) {
toolButton.Hidden = true;
return;
}
var n = availableItems.Length;
var minN = showIfOneRecord ? 1 : 2;
if (n >= minN) {
toolButton.Hidden = false;
var m = Math.Min(n, 10);
if (n > 10) {
m = 9;
}
for (var i = 0; i < m; i++) {
var recordData = availableItems[i];
var menuItem = new Terrasoft.UI.WebControls.Controls.MenuItem();
menuItem.Caption = recordData.Name;
menuItem.CreatedByAjax = true;
menuItem.EnableViewState = false;
menuItem.Name = string.Concat(allItemsMessage, "MenuItem", i.ToString());
menuItem.UId = Guid.NewGuid();
menuItem.Image = GetServiceObjectIconNew(recordData);
toolButton.Menu.Add(menuItem);
//HACK
//Page.AddScript(string.Format("{0} = {{}};{0}.setImage=Ext.emptyFn;", menuItem.ClientID));
menuItem.AllowCallbackScriptMonitoring = false;
var script = string.Format("window.{0} = {1};\n", menuItem.ClientID, menuItem.GenerateControlScript(true, null));
script += string.Format("{0}.getMenu().addItem(window.{1});\n", toolButton.ClientID, menuItem.ClientID);
script += string.Format("{0}.on('click', function() {{ {1}.setValueAndText('{2}', '{3}'); }}, this);\n", menuItem.ClientID, lookupEdit.ClientID, recordData.Id.ToString(), recordData.Name.Replace("'", @"\'").Replace("\""

А можно ли если не трудно прописать скрипт более детально? А то я что-то не поняла...

С уважением,

Лучше посмотрите целиком в карточке, если есть возможность посмотреть на Service Desk.
