  DomainDataSource.DataView Error Add new Record

  Mar 24, 2010 05:34 PM | LINK

  Hello,

  When adding a new record in DomainDataSource, do the following:
  
   

  ((IEditableCollectionView) pessoaDomainDataSource.DataView). AddNew () as Teste.Web.Contexts.pessoa;
  

   
  
  But if not carry anything in the DataGrid before, the above statement fails! To resolve this, I'm calling the Load () method as follows:
  

   

   if (pessoaDomainDataSource.DataView.CanAdd == false)
                  pessoaDomainDataSource.Load ();
  
  

    

  Correct?

  OK, I´m sorry for short description.

   

  Code of DataGrid

   

          <riaControls:DomainDataSource AutoLoad="False" d:DesignData="{d:DesignInstance my:pessoa, CreateList=true}" Height="0" LoadedData="pessoaDomainDataSource_LoadedData_8" Name="pessoaDomainDataSource" QueryName="InvokeGetPessoasPorNomeQuery" Width="0" >
              <riaControls:DomainDataSource.DomainContext>
                  <my1:PessoasContext />
              </riaControls:DomainDataSource.DomainContext>
              <riaControls:DomainDataSource.QueryParameters>
                  <riaControls:Parameter ParameterName="nomePessoa" Value="{Binding ElementName=nomePessoaTextBox, Path=Text}" />
              </riaControls:DomainDataSource.QueryParameters>
          </riaControls:DomainDataSource>
          <StackPanel Height="30" HorizontalAlignment="Left" Orientation="Horizontal" VerticalAlignment="Top">
              <sdk:Label Content="Nome Pessoa:" Margin="3" VerticalAlignment="Center" />
              <TextBox Name="nomePessoaTextBox" Width="566" />
              <Button Command="{Binding Path=LoadCommand, ElementName=pessoaDomainDataSource}" Content="Load" Margin="3" Name="pessoaDomainDataSourceLoadButton" />
          </StackPanel>
          <sdk:DataGrid AutoGenerateColumns="True" Height="141" HorizontalAlignment="Left" ItemsSource="{Binding ElementName=pessoaDomainDataSource, Path=Data}" Margin="85,36,0,0" Name="pessoaDataGrid" RowDetailsVisibilityMode="VisibleWhenSelected" VerticalAlignment="Top" Width="602" IsReadOnly="True">
          </sdk:DataGrid>
          <Button Content="Alterar" Height="23" HorizontalAlignment="Left" Margin="168,183,0,0" Name="button3" VerticalAlignment="Top" Width="75" Click="button3_Click" />
          <Button Content="Inserir" Height="23" HorizontalAlignment="Left" Margin="85,183,0,0" Name="button4" VerticalAlignment="Top" Width="75" Click="button4_Click" />
          <Button Content="Excluir" Height="23" HorizontalAlignment="Left" Margin="249,183,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click_1" />
  
  

  DataGrid  make with DataSource Wizard, after add tree buttons for basic operations.

  In button1_Click_1 event, add o following code:

   

              ChildWindow1 frm = new ChildWindow1();
              frm.dataForm1.CurrentItem = ((IEditableCollectionView)pessoaDomainDataSource.DataView).AddNew() as SistemaWEB.Web.Contexts.pessoa;
              frm.Closed += new EventHandler(frm_Closed2);
              frm.Show();                 
  
  

  
  When no data is researched and calls the code above, the following error is posted "'AddNew' is not supported by this ICollectionView."

  But if I search for something before, nothing happens.

  Environment:

  Windows 7 Professional

  Visual Studio 2010 RC + SilverLight 4
  

  SilverLight 4 Tools

  This may be a framework bug. Until we determine how to fix the bug, you can use this workaround to avoid it.

  Set the QueryName in the contructor of your page and not in xaml.

  public MyPage()
  {
    InitializeComponent();
  
    this.pessoaDomainDataSource.QueryName = "InvokeGetPessoasPorNomeQuery";
  
    // ...
  }

  You need to add the new Item to the DomainContext entity collection, not in the DataView:

  possoa p = new possoa();

  YourDomainContext.possoas.Add(p);
  

  frm.dataForm1.CurrentItem = p;

  If you only need to add item, not edit exiting items, you do not even need to call Load.

  Actually you should be able to add the entity a number of places (DataForm, DomainDataSource.DataView, or DomainContext). The current limitation is due to a bug.

  When no data is researched and calls the code above, the following error is posted "'AddNew' is not supported by this ICollectionView."

  should be the method "insert" for entity on the server side.

  [Insert]
  public void InsertBlaBla(BlaBla blaBla)
  {
  }
