How do I use a IQueryable return
I am using Sillverlight 4 Business Application
The Domain Service returns a EntityQuery
DomainService
public IQueryable<NFe_C_emit> GetNFe_C_emit()
{
return this.ObjectContext.NFe_C_e
}
My xaml
private void btnPesquisar_Click(object sender, RoutedEventArgs e)
{
dataGrid1.ItemsSource = db.GetNFe_C_emitQuery();
}
ERROR
Cannot implicitly convert type 'System.ServiceModel.Domai
Questions:
1) How can I convert this to a IEnumerable<> for use in a DataGrid
2) How can I access row by row of this return.
Thanks

dataGrid1.ItemsSource = db.GetNFe_C_emitQuery().As
for that to work you should have added System.Data.DataSetExtensi

However for the List does not work.
The operation [for each] performed before bringing the record.
As I await the end of the operation to run [for each]?
<OK>
private void btnPesquisar_Click(object sender, RoutedEventArgs e)
{
EntityQuery<NFe_C_emit> query =
from c in _customerContext.GetNFe_C_
select c;
LoadOperation<NFe_C_emit> loadOp = this._customerContext.Load
dataGrid1.ItemsSource = loadOp.Entities;
}
<NOT WORK>
private void btnSelecionar_Click(object
{
EntityQuery<NFe_C_emit> query =
from c in _customerContext.GetNFe_C_
select c;
LoadOperation<NFe_C_emit> loadOp = this._customerContext.Load
List<NFe_C_emit> list = loadOp.Entities.ToList();
foreach (NFe_C_emit item in list)
{
textBox1.Text = item.xNome;
}
}
