的」數據上下文解決財產「myObservableCollection」我有一個叫STOCKAGE類繼承INotifyPropertyChanged的。 這個類設置一些字符串,然後創建ObservableCollections的一個ObservableCollection這的ObservableCollection發送值幾個字符串之前設置無法在類型「namespace.class」
這樣的:
public class Stockage:INotifyPropertyChanged
{
public string Flag { get; set; }
public string GroupeAlerte { get; set; }
public string Pmid { get; set; }
public string LibellePmrq { get; set; }
public string Ligne { get; set; }
public string Otm { get; set; }
public string Totm { get; set; }
public string LibelleTotm { get; set; }
public string Discipline { get; set; }
public string DisciplineSubstituee { get; set; }
public string Remarque { get; set; }
public static ObservableCollection<Stockage> result = new ObservableCollection<Stockage>();
public static ObservableCollection<Stockage> Load(ObservableCollection<Resultat> listResult,
ObservableCollection<D98Equipements> equipementses,
ObservableCollection<D98Details> detailses,
ObservableCollection<D675> d675Ses,
ObservableCollection<Activite> activitees)
{
foreach (var resultat in listResult)
{
result.Add(new Stockage{Flag=activitees.FirstOrDefault(e=>resultat.TOTMPMRQ == e.PMRQTOTMActivite).Flag.ToString(),
Pmid = listResult.FirstOrDefault(e=>resultat.TOTMPMRQ == e.TOTMPMRQ).TOTMPMRQ.Substring(0,8),
LibellePmrq = listResult.FirstOrDefault(e => resultat.TOTMPMRQ == e.TOTMPMRQ).LibelléTOTApres,
GroupeAlerte = listResult.FirstOrDefault(e => resultat.TOTMPMRQ == e.TOTMPMRQ).Groupe_D_alerte,
Ligne = listResult.FirstOrDefault(e => resultat.TOTMPMRQ == e.TOTMPMRQ).TOTMPMRQ.Substring(8, 2),
Otm = listResult.FirstOrDefault(e=>resultat.TOTMPMRQ == e.TOTMPMRQ).TOTMPMRQ.Substring(10,8),
Totm = listResult.FirstOrDefault(e=>resultat.TOTMPMRQ == e.TOTMPMRQ).TOTMPMRQ.Substring(18,2),
LibelleTotm = equipementses.FirstOrDefault(e=>resultat.TOTMPMRQ == e.PMRQTOTM).Libellé,
Discipline = detailses.FirstOrDefault(e=>resultat.TOTMPMRQ == e.TOTMPMRQ).Discipline,
DisciplineSubstituee = detailses.FirstOrDefault(e=>resultat.TOTMPMRQ == e.TOTMPMRQ).Discipline,
Remarque = listResult.FirstOrDefault(e => resultat.TOTMPMRQ == e.TOTMPMRQ).Remarque,
});
}
return result;
}
**public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged(string property)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}**
的ObservableCollections在稱爲視圖模型的其他類設置和繼承INotifyPropertyChanged的太多:
class ViewModel:INotifyPropertyChanged
{
private BDDInterneEntities _BDDInterneEntities;
public ViewModel()
{
_BDDInterneEntities = new BDDInterneEntities();
ResultatCollection = new ObservableCollection<Resultat>(_BDDInterneEntities.Resultat);
D98EquipementsCollection = new ObservableCollection<D98Equipements>(_BDDInterneEntities.D98Equipements);
D98DetailsCollection = new ObservableCollection<D98Details>(_BDDInterneEntities.D98Details);
D675Collection = new ObservableCollection<D675>(_BDDInterneEntities.D675);
ActiviteCollection = new ObservableCollection<Activite>(_BDDInterneEntities.Activite);
}
public ObservableCollection<Resultat> ResultatCollection { get; set; }
public ObservableCollection<D98Equipements> D98EquipementsCollection { get; set; }
public ObservableCollection<D98Details> D98DetailsCollection { get; set; }
public ObservableCollection<D675> D675Collection { get; set; }
public ObservableCollection<Activite> ActiviteCollection { get; set; }
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged(string property)
{
if(PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}
我想送ObservableCollections(result
)到DataGrid的的ObservableCollection,所以我將DataGrid綁定到集合,然後我綁定每個DataGridTextColumn與它的前設置相應的字符串。就像這樣:
<DataGrid x:Name="DonneesBrutes" IsReadOnly="True" ItemsSource="{Binding Path=result}" Margin="10,65,0,0" AutoGenerateColumns="False" EnableRowVirtualization="True" RowDetailsVisibilityMode="VisibleWhenSelected">
<DataGrid.Columns>
<DataGridTextColumn x:Name="PrisEnCompte" Binding="{Binding Path=Flag}" Header="Pris En Compte"></DataGridTextColumn>
<DataGridTextColumn x:Name="PMRQ" Width="*" Binding="{Binding Path=Pmid}" Header="PMID"></DataGridTextColumn>
<DataGridTextColumn x:Name="Ligne" Width="40" Binding="{Binding Path=Ligne}" Header="Ligne" IsReadOnly="True"></DataGridTextColumn>
<DataGridTextColumn x:Name="LibellePMRQ" Width="*" Binding="{Binding Path=LibellePmrq}" Header="Libellé PMRQ"></DataGridTextColumn>
<DataGridTextColumn x:Name="OTM" Width="*" Binding="{Binding Path=Otm}" Header="OTM"></DataGridTextColumn>
<DataGridTextColumn x:Name="TOTM" Width="50" Binding="{Binding Path=Totm}" Header="TOTM"></DataGridTextColumn>
<DataGridTextColumn x:Name="LibelleTOTM" Width="*" Binding="{Binding Path=LibelleTotm}" Header="Libellé OTM"></DataGridTextColumn>
<DataGridTextColumn x:Name="GA" Width="70" Binding="{Binding Path=GroupeAlerte}" Header="GA"></DataGridTextColumn>
<DataGridTextColumn x:Name="Discipline" Width="120" Binding="{Binding Path=Discipline}" Header="Discipline"></DataGridTextColumn>
<DataGridTextColumn x:Name="DisciplineSubstituee" Width="120" Binding="{Binding Path=DisciplineSubstituee}" Header="Discipline Substituée"></DataGridTextColumn>
<DataGridTextColumn x:Name="Remarque" Width="*" Binding="{Binding Path=.Remarque}" Header="Remarque"></DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
,當然我之前,我確切我使用的是類STOCKAGE,包含我ObservableCollections的的ObservableCollection,result
類定義<Window.DataContext> <local:Stockage/> </Window.DataContext>
。
的問題,在我的DataGrid的ItemsSource="{Binding Path=result}"
,結果「不能用在「WpfApplication3.Stockage`(我namespace.MyClassContainingMyCollectionResult)
類型的數據上下文解決財產我想我叫什麼不對,或者我做了一些禁止的事情,我儘量給出儘可能多的關於結果的信息,我稱之爲,怎麼樣,希望我提供了足夠的信息,並且我不太模糊,如果缺少某些東西,我可以編輯我的代碼。
感謝您的幫助,祝賀您讀了這篇文章結束。
問候。
EDIT1 的OnPropertyChanged的眨了眨眼,而且,我已經修改結果的聲明。
的第一件事,我已經beclared結果是這樣的:'公共靜態的ObservableCollection結果=新的ObservableCollection ();'只是'公共靜態的ObservableCollection Load' 而且之前,我有'公共事件PropertyChangedEventHandler的PropertyChanged ; 私人無效OnPropertyChanged(字符串屬性) { 如果(的PropertyChanged!= NULL){ 的PropertyChanged(這一點,新PropertyChangedEventArgs(屬性)); } }'返回結果後,我編輯我的代碼,我想我忘了寫它。 –

好吧,現在我在'ItemsSource =「{Binding Path = result}上有另外一個錯誤''''''''''''我期望'result'結果'我必須做'result.Something'嗎?如果您喜歡這個新問題,我可以創建另一個主題。 – Flo 2014-09-23 08:34:13
*如果您喜歡這個新問題,我可以創建另一個主題* ...或許這樣會更好,因爲現在您已更改代碼並使這兩個答案看起來很奇怪,因此此問題變得非常混亂。請在您的新問題中包含*完整*錯誤的詳細信息。 – Sheridan 2014-09-23 08:38:33
