I have the same issue as the below link but with a different graph (APPrintChecks)
how-do-i-override-pxfilteredprocessingjoin-in-a-graph-extension-without-altering
I am overriding the main view to pull in the remittance name from APContact to show in the grid.
[PXFilterable]
public PXFilteredProcessingJoin<APPayment, PrintChecksFilter,
InnerJoin<Vendor, On<Vendor.bAccountID, Equal<APPayment.vendorID>>,
InnerJoin<APContact, On<APContact.contactID, Equal<APPayment.remitContactID>>>>,
Where<boolTrue, Equal<boolTrue>>,
OrderBy<Asc<Vendor.acctName, Asc<APPayment.refNbr>>>> APPaymentList;
However, I do not know how to override the delegate so I won't have the same problem as the other poster (no filter being applied).
protected virtual IEnumerable appaymentlist()
{
if (cleared)
{
foreach (APPayment doc in APPaymentList.Cache.Updated)
{
doc.Passed = false;
}
}
foreach (PXResult<APPayment, Vendor, PaymentMethod, CABatchDetail> doc in PXSelectJoin<APPayment,
InnerJoinSingleTable<Vendor, On<Vendor.bAccountID, Equal<APPayment.vendorID>>,
InnerJoin<PaymentMethod, On<PaymentMethod.paymentMethodID, Equal<APPayment.paymentMethodID>>,
LeftJoin<CABatchDetail, On<CABatchDetail.origModule, Equal<BatchModule.moduleAP>,
And<CABatchDetail.origDocType, Equal<APPayment.docType>,
And<CABatchDetail.origRefNbr, Equal<APPayment.refNbr>>>>>>>,
Where2<Where<APPayment.status, Equal<APDocStatus.pendingPrint>,
And<CABatchDetail.batchNbr, IsNull,
And<APPayment.cashAccountID, Equal<Current<PrintChecksFilter.payAccountID>>,
And<APPayment.paymentMethodID, Equal<Current<PrintChecksFilter.payTypeID>>,
And<Match<Vendor, Current<AccessInfo.userName>>>>>>>,
And<APPayment.docType, In3<APDocType.check, APDocType.prepayment, APDocType.quickCheck>>>>.Select(this))
{
yield return new PXResult<APPayment, Vendor>(doc, doc);
if (_copies.ContainsKey((APPayment)doc))
{
_copies.Remove((APPayment)doc);
}
_copies.Add((APPayment)doc, PXCache<APPayment>.CreateCopy(doc));
}
}
There are other private variables that are referenced in this. Any help appreciated.
Also, if there's a simpler way to pull in a related value on a grid like this (virtual field in DAC?) I'm not stuck on doing it with a graph extension.
So this appears to work but it seems messy and duplicates a lot of code and private variables. Appreciate any feedback if there's a better way to do this:
public class APPrintChecks_Extension : PXGraphExtension<APPrintChecks> {
[PXFilterable]
public PXFilteredProcessingJoin<APPayment, PrintChecksFilter,
InnerJoin<Vendor, On<Vendor.bAccountID, Equal<APPayment.vendorID>>,
InnerJoin<APContact, On<APContact.contactID, Equal<APPayment.remitContactID>>>>,
Where<boolTrue, Equal<boolTrue>>,
OrderBy<Asc<Vendor.acctName, Asc<APPayment.refNbr>>>> APPaymentList;
public IEnumerable appaymentlist()
{
if (cleared)
{
foreach (APPayment doc in APPaymentList.Cache.Updated)
{
doc.Passed = false;
}
}
foreach (PXResult<APPayment, Vendor, APContact, PaymentMethod, CABatchDetail> doc in PXSelectJoin<APPayment,
InnerJoinSingleTable<Vendor, On<Vendor.bAccountID, Equal<APPayment.vendorID>>,
InnerJoin<APContact, On<APContact.contactID, Equal<APPayment.remitContactID>>,
InnerJoin<PaymentMethod, On<PaymentMethod.paymentMethodID, Equal<APPayment.paymentMethodID>>,
LeftJoin<CABatchDetail, On<CABatchDetail.origModule, Equal<BatchModule.moduleAP>,
And<CABatchDetail.origDocType, Equal<APPayment.docType>,
And<CABatchDetail.origRefNbr, Equal<APPayment.refNbr>>>>>>>>,
Where2<Where<APPayment.status, Equal<APDocStatus.pendingPrint>,
And<CABatchDetail.batchNbr, IsNull,
And<APPayment.cashAccountID, Equal<Current<PrintChecksFilter.payAccountID>>,
And<APPayment.paymentMethodID, Equal<Current<PrintChecksFilter.payTypeID>>,
And<Match<Vendor, Current<AccessInfo.userName>>>>>>>,
And<APPayment.docType, In3<APDocType.check, APDocType.prepayment, APDocType.quickCheck>>>>.Select(Base))
{
yield return new PXResult<APPayment, Vendor, APContact>(doc, doc, doc);
if (_copies.ContainsKey((APPayment)doc))
{
_copies.Remove((APPayment)doc);
}
_copies.Add((APPayment)doc, PXCache<APPayment>.CreateCopy(doc));
}
}
private bool cleared;
public void Clear()
{
Base.Filter.Current.CurySelTotal = 0m;
Base.Filter.Current.SelTotal = 0m;
Base.Filter.Current.SelCount = 0;
cleared = true;
Base.Clear();
}
private readonly Dictionary<object, object> _copies = new Dictionary<object, object>();
}
Per Rick's suggestion I implemented the FieldSelecting method. Much, much simpler/cleaner code. It does in fact cause a round trip to the database for each row when using this in a grid column, however, for check printing this should be acceptable. Thanks Rick! Code below.
protected void APPayment_UsrRemitTo_FieldSelecting(PXCache cache, PXFieldSelectingEventArgs e)
{
var row = (APPayment)e.Row;
// fill usrRemitTo from APContact
if (row != null)
{
var extension = PXCache<APRegister>.GetExtension<APRegisterExt>(row);
using (PXConnectionScope cs = new PXConnectionScope())
{
APContact rec = PXSelectReadonly<APContact, Where<APContact.contactID, Equal<Required<APPayment.remitContactID>>>>.Select(Base, row.RemitContactID);
if (rec != null)
{
string remitToName = (!string.IsNullOrEmpty(rec.FullName)) ? rec.FullName : "";
e.ReturnValue = remitToName;
}
else
{
e.ReturnValue = "";
}
}
}
}
Using DBScalar, you can further simplify your event with just one line :
public class APPaymentExt : PXCacheExtension<APPayment>
{
#region UsrRemitTo
[PXString(100)]
[PXUIField(DisplayName="Remit To")]
[PXDBScalar(typeof(Search<APContact.fullName,Where<APContact.contactID, Equal<APPayment.remitContactID>>>))]
public virtual string UsrRemitTo { get; set; }
public abstract class usrRemitTo : PX.Data.BQL.BqlString.Field<usrRemitTo> { }
#endregion
}
Good afternoon.
I was using Xamarin and MVVMCROSS version 5.0 to create multiple tabs and navigate them between them.
In my code i have a Root page that directs to the pages:
[MvxRootPresentation(WrapInNavigationController = true)]
public sealed partial class RootView : MvxTabBarViewController<RootViewModel>
{
private bool _isPresentedFirstTime = true;
public RootView()
{
// ViewDidLoad();
}
public override void ViewWillAppear(bool animated)
{
base.ViewWillAppear(animated);
if (ViewModel != null && _isPresentedFirstTime)
{
_isPresentedFirstTime = false;
ViewModel.ShowInitialViewModels();
}
//Alterando o BackGround da tabBar
this.TabBar.BarTintColor = UIColor.FromRGBA(237, 146, 4, 1);
this.TabBar.Translucent = false;
//this.TabBar.Opaque = false;
//Cor do ícone antes de selecionado
this.TabBar.UnselectedItemTintColor = UIColor.White;
//Cor do ícone após seleção
this.TabBar.SelectedImageTintColor = UIColor.Black;
//Setando imagem antes e depois da seleção
this.TabBar.Items[4].Image = UIImage.FromBundle("valdemarMenuBar.png").ImageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);
this.TabBar.Items[4].SelectedImage = UIImage.FromBundle("valdemarMenuBar.png").ImageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);
}
...
In each of the Views I set the Titles of the navigations bars according to the example below:
[MvxTabPresentation(WrapInNavigationController = true, TabIconName = "newOrder", TabName = "Novo Pedido")]
public partial class NewOrder2ViewController : BaseScrollViewController
{
public override void ViewDidLoad()
{
base.ViewDidLoad();
if (ViewModel == null)
{
return;
}
Title = "Novo Pedido";
...
When I upgraded to version 5.1.1 of MVVMCROSS this functionality has stopped.
Can anyone help me about what happened.
I did not find anything in the documentation for this new version of MVVMCROSS.
Thank you very much in advance.
You're seeing this strange behavior because you have two UINavigationControllers ovelapped on each tab, one over the other (this is because your TabBarViewController is wrapped in a navigation controller).
In order to fix it, you just need to change the value of the attribute property:
[MvxRootPresentation(WrapInNavigationController = false)]
public sealed partial class RootView : MvxTabBarViewController<RootViewModel>
{
//...
}
EDIT 2: If you're looking for an answer to a similar problem, check Stuart's answer and my comments on it.
EDIT: I am actually getting a Mono.Debugger.Soft.VMDisconnectedException. I also recently installed Windows 8.1 and Resharper (though Resharper is suspended now).
When I access a very simple list property of my view model in my MVVMCross Xamarin iOS application, the program fails. It doesn't quit most of the time: it acts like it's running. The simulator has a black screen and there is no exception. If I breakpoint on if (messagesViewModel != null) source.ItemsSource = messagesViewModel.Messages; and then type messagesViewModel.Messages into the Immediate Window, everything stops, so I can tell it is failing at this line. If instead I "step over", it never moves to the next line.
I was having similar behavior when I was toggling this code in the MvxTableViewSource:
public override int RowsInSection(UITableView tableview, int section)
{
return 1;
}
My view model looks like this:
public class MessagesViewModel : MvxViewModel
{
private List<BaseMessage> _messages = null;
public List<BaseMessage> Messages
{
get
{
return _messages; //yes, I know I'm returning null
//I wasn't at first.
}
}
public MessagesViewModel()
{
}
}
This is my ViewDIdLoad on the MvxTableViewController:
public override void ViewDidLoad()
{
base.ViewDidLoad();
var source = new MessagesTableViewSource(TableView);
//was binding here, removed it for debug purposes
//failure on second line here
var messagesViewModel = ViewModel as MessagesViewModel;
if (messagesViewModel != null) source.ItemsSource = messagesViewModel.Messages;
TableView.Source = source;
TableView.ReloadData();
}
Some initialization code:
public class App : MvxApplication
{
public App()
{
var appStart = new MvxAppStart<MessagesViewModel>();
Mvx.RegisterSingleton<IMvxAppStart>(appStart);
}
}
public partial class AppDelegate : MvxApplicationDelegate
{
//empty functions removed.
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
Window = new UIWindow(UIScreen.MainScreen.Bounds);
var presenter = new MvxTouchViewPresenter(this, Window);
var setup = new Setup(this, presenter);
setup.Initialize();
var startup = Mvx.Resolve<IMvxAppStart>();
startup.Start();
Window.MakeKeyAndVisible();
return true;
}
}
I suspect whatever the error is, it isn't in any of the code you have posted.
I just created a simple ViewModel:
public class FirstViewModel
: MvxViewModel
{
private List<string> _items = new List<string>() { "One", "Two", "Three"};
public List<string> Items
{
get { return _items; }
set { _items = value; RaisePropertyChanged(() => Items); }
}
}
And a simple View:
[Register("FirstView")]
public class FirstView : MvxTableViewController
{
public override void ViewDidLoad()
{
base.ViewDidLoad();
// ios7 layout
if (RespondsToSelector(new Selector("edgesForExtendedLayout")))
EdgesForExtendedLayout = UIRectEdge.None;
var firstViewModel = ViewModel as FirstViewModel;
var source = new MessagesTableViewSource(TableView);
source.ItemsSource = firstViewModel.Items;
TableView.Source = source;
}
public class MessagesTableViewSource : MvxTableViewSource
{
public MessagesTableViewSource(UITableView tableView) : base(tableView)
{
tableView.RegisterClassForCellReuse(typeof(MessagesCell), new NSString("MessagesCell"));
}
protected override UITableViewCell GetOrCreateCellFor(UITableView tableView, NSIndexPath indexPath, object item)
{
return tableView.DequeueReusableCell("MessagesCell");
}
}
public class MessagesCell : MvxTableViewCell
{
public MessagesCell(IntPtr handle)
: base(handle)
{
var txt = new UILabel(new RectangleF(0, 0, 320, 44));
Add(txt);
this.DelayBind(() =>
{
this.CreateBinding(txt).Apply();
});
}
}
}
And this code runs fine...
I wouldn't completely trust the integration of Xamarin.iOS with the Immediate window - it is better now than it used to be, but I've seen several problems with it before.
Some things to possibly check:
does the above code work for you?
if it does, then what's in your BaseMessage and MessagesTableViewSource classes - perhaps they are causing the problem?
can you use Mvx.Trace("The list is {0}", messagesViewModel.Messages ?? "-null") to view the list? Can you use trace within the ViewModel property get - is it being called? Can you use trace within the ViewModel constructor?
are all your assemblies building against the same versions of things? Are all your assemblies definitely rebuilt? (Check "Build|Configuration Manager")- what version of Xamarin.iOS are you running in VS and in the Mac?
I'm using this code to create the dialog:
SettingsDialog settingDialog = new SettingsDialog ();
RootElement dialog = settingDialog.CreateDialog ();
DialogViewController dv = new DialogViewController (dialog, true);
dv.ViewDissapearing += delegate(object sender1, EventArgs e1) {
// update the values
Config.VendorId = settingDialog.VendorId;
} ;
NavigationController.PushViewController (dv, true);
Ths is the code for the SettingsDialogClass
public class SettingsDialog
{
private EntryElement idElement;
public RootElement CreateDialog ()
{
idElement = new EntryElement ("Vendor Id", string.Empty, Config.VendorId.ToString (CultureInfo.InvariantCulture)){ KeyboardType = UIKeyboardType.NumberPad };
element = new RootElement ("Configuration"){
new Section (){
idElement
} ,
...
}
public string VendorId {
get {
return idElement.Value;
}
}
The problem is that the above property ALWAYS returns the old value, it never gets updated.
Any idea why?
Thank,
Ignacio
I found the answer to my question, this thread had the key to it
How can I pass data into MonoTouch.Dialog's delegates?
this line:
i was able to get around it by calling field.FetchValue() before trying to retrieve it
So I modified the property as
public string VendorId {
get {
idElement.FetchValue();
return idElement.Value;
}
}
From this example http://www.smartclient.com/smartgwt/showcase/#tree_databinding_local , I started to implement my own tree structure dynamically (TreeGrid). When I try to render it, I get this error (title).
public class ProjectTreeGridScreen extends Screen {
Tree tree;
#Override
protected void onLoad() {
super.onLoad();
TreeGrid treeGrid = new TreeGrid();
setPageTitle(Util.C.projectListTitle());
treeGrid.setWidth(600);
treeGrid.setHeight(400);
TreeGridField projectTree = new TreeGridField("ProjectName", "Project Tree");
TreeGridField projectPath = new TreeGridField("ProjectPath", "Complete path");
TreeGridField projectDescription = new TreeGridField("ProjectDescription", "Description");
TreeGridField projectInfo = new TreeGridField("ProjectInfo", "Information");
treeGrid.setFields(projectTree, projectPath, projectDescription, projectInfo);
treeGrid.setData(tree);
add(treeGrid);
}
#Override
protected void onInitUI() {
super.onInitUI();
tree = new Tree();
tree.setModelType(TreeModelType.PARENT);
tree.setNameProperty("ProjectName");
tree.setIdField("ProjectItem");
tree.setParentIdField("ProjectParent");
tree.setShowRoot(true);
populateProjects();
}
protected void populateProjects() {
Util.PROJECT_SVC.visibleProjects(
new ScreenLoadCallback<List<Project>>(this) {
#Override
public void preDisplay(final List<Project> result) {
tree.setData(ProjectTreeGridBuilder.fromRepositories(result));
}
});
}
}
what do you mean by "x"? Normally, If a component has been drawn on the window (implicit or explicit call to draw), you cannot change it's properties values. So the only possible solution is to recreate the object with the new X value each time it is changing.
