I am using caliburn.micro framework.
BlogDetailViewModel.cs
private long _entryId;
public long entryId
{
get { return _entryId; }
set
{
_entryId = value;
NotifyOfPropertyChange(() => blogdetail);
}
}
private BlogEntry _blogdetail;
public BlogEntry blogdetail
{
get { return _blogdetail; }
set { _blogdetail = value; NotifyOfPropertyChange(() => blogdetail); }
}
protected override async void OnInitialize()
{
string s = await BlogManager.Instance.GetBlogDetail(entryId);
blogdetail = JsonConvert.DeserializeObject<BlogEntry>(s);
}
and BlogDetailView
I bind blogdetail to gridview using ItemSource Property
But i get Value does not fall within the expected range in Caliburn.Micro.
Unit you get a response from your async call to the BlogManager your blogdetail is not yet set. CM will renders your View before blogdetail is populated and is failing. Init _blogdetail in your Constructor.
PS: In c# the public proberties begin with a capital letter;

When I make updates inside a property of SortedList type of a document (haven't checked other Dictionary / List types) Those updates are ignored by the serialization process (even by the ToString method of the object).
Example:
using Microsoft.Azure.Documents;
public class BusinessStats : Document
{
public BusinessStats()
{
}
public BusinessStats(int businessId)
{
this.Id = businessId.ToString();
Counts = new SortedList<int, int>();
}
/// <summary>
/// Business id
/// </summary>
public override string Id
{
get
{
return base.Id;
}
set
{
base.Id = value;
}
}
[JsonProperty()]
public SortedList<int, int> Counts { get; set; }
}
public static class Test
{
BusinessStats bizStats = DocumentDB.Client.CreateDocumentQuery<BusinessStats>(DocumentDB.BusinessStats.SelfLink).Where(s => s.Id == p.BusinessId.ToString()).ToArray().FirstOrDefault();
if (bizStats == null)
{
bizStats = new BusinessStats(p.BusinessId);
}
}
if ( ! bizStats.Counts.ContainsKey(1))
{
bizStats.Counts.Add(1, 10);
}
else
{
bizStats.Counts[1] = bizStats.Counts[1] + 1;
}
var updateOperation = await DocumentDB.Client.UpsertDocumentAsync(DocumentDB.BusinessStats.DocumentsLink, bizStats);
First time this runs and inserts a proper Json, second time it reads the proper json, and deserialization goes well.
then, after it updates Counts[1] to be 11, it doesn't effect the ToString() and serialization of bizStats.
DocumentDB's .NET SDK makes me sad
I have a custom object with varying datatypes for each property.
I would like to be able to do something like:
public void evalCI(configurationItem CI)
{
foreach (PropertyInformation n in CI)
{
Response.Write(n.Name.ToString() + ": " + n.Value.ToString() + "</br>");
}
}
My custom object is:
public class configurationItem : IEnumerable
{
private string serial;
private string model;
private DateTime? wstart;
private DateTime? wend;
private Int32 daysLeft;
private string platform;
private string productVersion;
private string manufacturer;
private bool verificationFlag;
IEnumerator IEnumerable.GetEnumerator()
{
return (IEnumerator)GetEnumerator();
}
public string Serial
{
set { serial = value; }
get { return serial; }
}
public string Model
{
set { model = value; }
get { return model; }
}
public DateTime? Wstart
{
set { wstart = value; }
get { return wstart; }
}
public DateTime? Wend
{
set { wend = value; }
get { return wend; }
}
public Int32 DaysLeft
{
set { daysLeft = value; }
get { return daysLeft; }
}
public string Platform
{
set { platform = value; }
get { return platform; }
}
public string ProductVersion
{
set { productVersion = value; }
get { return productVersion; }
}
public string Manufacturer
{
set { manufacturer = value; }
get { return manufacturer; }
}
public bool VerificationFlag
{
set { verificationFlag = value; }
get { return verificationFlag; }
}
My expected output would be:
-Serial: 1234567
-Model: Mustang
-Wstart: 12/12/2005
-Wend: 12/11/2006
-DaysLeft: 0
-Platform: Car
-ProductVersion: GT
-Manufacturer: Ford
-VerificationFlag: true
At first I was getting an error that GetEnumerator() had to be implemented to use a foreach loop. The problem I keep running into is that all of the examples of Indexed Properties are of a single property with an indexable list, instead of an index for each property in the object. I was able to get intellisense to give me methods for PropertyInfo by adding:
IEnumerator IEnumerable.GetEnumerator()
{
return (IEnumerator)GetEnumerator();
}
However, the 2nd GetEnumerator() throws:
Compiler Error Message: CS0103: The name 'GetEnumerator' does not exist in the current context.
What am I missing here? How do I modify my object to give me the results I expect from evalCI()?
You don't need to implement IEnumerable. What you do need to do is use Reflection.
This is from memory, but I believe it would look like this:
foreach (PropertyInfo n in typeof(configurationItem).GetProperties())
{
Response.Write(string.Format("{0}: {1}<br/>", n.Name, n.GetValue(CI, null)));
}
This - the code as written - will also only give you public properties, and non-indexed properties (but it doesn't look like you have any indexed properties).
I am having a problem that is driving me nuts.
Recently I configured my BlazeDS to use Array instead of ArrayCollection for performance reasons. Additionally I adjusted my templates to generate Array properties.
Everything wen't fine. All except one function that causes TypeError: Error #1034. These are being thrown before the result callback is called. It claims to have problems casting an ArrayCollection to Array. I removed the generated types to make Flex use Objects instead, but these did not contain any ArrayCollections. My question now is: How can I get the stack-traces of errors thrown in event-handlers?
I allready added handlers for unhandledExceptions in all of my modules and they are called if errors occur in code triggered from user-interaction, but they don't seem to be able to catch stuff thrown by event-handlers.
How can I track these Errors?

Both classes are generated by my maven build from a corresponding Java Class and the Types do fit together nicely.
Do you have access to the socket class that's reading in all these messages? Trace out the buffer before the deserialisation and you should at least be able to find the class that's giving you hassle.
Failing that, trace out the object after deserialisation and it should be the very first one after the error is thrown.
This is something you'll have to debug on your own, but I have a gut feeling that the problem is because the data being sent by your java DTO is not the same as your AS3 class, even though that you have the RemoteClass metadata saying that it is.
Are you missing a property? or have a property mismatch? That is the most likely cause of your error. I suggest you debug the java side as much as you can and use something like firebug to see the request/response of the server.
Attempting to take the data in my gridview and convert it back into a list so I can run an update function. Currently I'm getting a null value when I attempt this.
List<CodeEntity> codes = new List<CodeEntity>();
codes = (List<CodeEntity>)Convert.ChangeType(gdvFGCode.DataSource,typeof(List<CodeEntity>));
Response.Write(codes[0].FGCode);
Also, Since the Gridview contains 3 template fields all with controls inside, would the datasource returned contain the updated values from the controls or would it return the original List<> pasted into it.
EDIT: The class I'm attempting to return in the list
public class CodeEntity
{
private string _fgCode;
private Int16 _palletSet;
private bool _priority;
private int _codeState;
private string _formingCode;
private string _d4Code;
public string FGCode
{
get { return _fgCode; }
set { _fgCode = value; }
}
public int CodeState
{
get { return _codeState; }
set { _codeState = value; }
}
public Int16 PalletSet
{
get { return _palletSet; }
set { _palletSet = value; }
}
public bool Priority
{
get { return _priority; }
set { _priority = value; }
}
public string FormingCode
{
get { return _formingCode; }
set { _formingCode = value; }
}
public string D4Code
{
get { return _d4Code; }
set { _d4Code = value; }
}
}
I would think the following should work:
if (gdvFGCode.DataSource != null)
{
List<CodeEntity> codes = (List<CodeEntity>)gdvFGCode.DataSource;
}
Edit
Added null check on the Datasource and updated code to accurately reflect OP's code.
I have a Flex Spark dropdownList in which I need to show the Provider FirstName,LastName:
<s:DropDownList id="providerList"
dataProvider="{model.practiceProviderList.practiceProviders}"
labelField="provider.providerName.firstName"/>
But the output shows only [object Object] & [object Object] as there are 2 providers in the DB and does not show the actual values.
The PracticeProviderList.as:
[Bindable]
[RemoteClass(alias="model.PracticeProviderList")]
public class PracticeProviderList extends PracticeProviderListBase {
private var _practiceProviderList:ArrayCollection;
public function get practiceProviders():ArrayCollection
{
return _practiceProviderList;
}
public function set practiceProviders(value:ArrayCollection):void
{
_practiceProviderList = value;
}
The PracticeProvider Object:
public class PracticeProvider {
private var _practiceId:Number;
private var _practiceProviderId:Number;
private var _provider:Provider;
public function set practiceId(value:Number):void {
_practiceId = value;
}
public function get practiceId():Number {
return _practiceId;
}
public function set practiceProviderId(value:Number):void {
_practiceProviderId = value;
}
public function get practiceProviderId():Number {
return _practiceProviderId;
}
public function set provider(value:Provider):void {
_provider = value;
}
public function get provider():Provider {
return _provider;
}
The Provider has providerName:PersonName as one of it's fields & PersonName has firstName:String & lastName:String
I need to show the First Name, Last Name in the dropdownlist. I would appreciate if someone can help in this regard.
Thanks
Harish
The labelField can't concatenate 2 values. Use a labelFunction instead.
If I understand your data model, Something like this:
public function myLabelFunction(item:Object):String{
return item['providerName']['PersonName']['firstName'] + ' ' + item['providerName']['PersonName']['lastName']
}
