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
}
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 wan't to use UITableView.AllowsMultipleSelectionDuringEditing with Monotouch.Dialog. If the property is set to true, the click on the table (with edit mode enabled) seems to be ignored (no selection happens). If there is an Element.Tapped, it will be executed. In my current implementation it will push a new UIView to the NavigationController, but this is not what you expect in edit-mode.
You can reproduce the behaviour with the monotouch.dialog-sample project, just change the EditingDialog Constructor (DemoEditing.cs:57) to the following:
public EditingDialog (RootElement root, bool pushing) : base (root, pushing)
{
TableView.AllowsMultipleSelectionDuringEditing = true;
}
Is there a way to use AllowsMultipleSelectionDuringEditing? If yes, what's wrong with my approach?
I just had the same problem with my own code. The problem is that some of the MonoTouch.Dialog elements have their cell SelectionStyle set to UITableViewCellSelectionStyle.None.
I solved it by sub-classing Source or SizingSource:
public class MyTableViewSource : Source
{
public MyTableViewSource(DialogViewController container) : base(container)
{
}
public override UITableViewCell GetCell(UITableView tableView, NSIndexPath indexPath)
{
var cell = base.GetCell(tableView, indexPath);
cell.SelectionStyle = UITableViewCellSelectionStyle.Gray; // something other than None
return cell;
}
}
Then in your DialogViewController:
public class MyDialogController : DialogViewController
{
public override void ViewDidLoad()
{
base.ViewDidLoad();
// setup root element
Root = new RootElement();
// . . .
TableView.Source = new MyTableViewSource(this);
TableView.AllowsMultipleSelectionDuringEditing = true;
}
}
I'm using Monotouch.Dialog and
I have subclassed the class Section to implement a custom HeaderView. The problem is that the header view is automatically resized, here's the code I'm using :
public class MySection : Section
{
public MySection ()
{
UIView v = new UIView(new RectangleF(0,0,30,30));
v.BackgroundColor = UIColor.Red;
this.HeaderView = v;
}
}
I've attached the screen shot :
http://imageshack.us/photo/my-images/864/capturedcran20120508212.png
EDIT
Ok I've kind of find the way to resolve this
The trick is to add a View that will contain your real HeaderView and sets the AutosizesSubviews property to false. Then just add the view to the latest :
public class MySection : Section
{
public MySection ()
{
UIView v0 = new UIView(new RectangleF(0,0,50, 60));
v0.AutosizesSubviews = false;
UIView v = new UIView(new RectangleF(0,0,30,30));
v.BackgroundColor = UIColor.Red;
v0.AddSubview(v);
this.HeaderView = v0;
}
}
this is the code of my page:
OrganizationContext ctx = new OrganizationContext();
public EmployeeList()
{
InitializeComponent();
ctx.Load(ctx.GetEmployeesQuery(), LoadBehavior.MergeIntoCurrent, EmployeesLoaded, null);
}
private void EmployeesLoaded(LoadOperation lo)
{
dataGrid1.ItemsSource = lo.Entities;
}
The callback executes, and the LoadOperation.Entities.Count is 291 but for some reason the grid doesnt display anything. By the way i've tried setting the DataContext property and still doesnt work.
1st,make your DataGrid's attribute AutoGenerateColumns="True";
2nd the code should like:
OrganizationContext ctx = new OrganizationContext();
public EmployeeList()
{
InitializeComponent();
LoadOperation lo=ctx.Load(ctx.GetEmployeesQuery());
dataGrid1.ItemsSource = lo.Entities;
}
