hii everyone. i m a beginner in silverlight . In my silverlight application i have a datagrid to patient list. for this list i have created a WCF wef service which returns a datatable as follows:
namespace
Tab.Web
{
[
ServiceContract(Namespace =
"")]
[
AspNetCompatibilityRequirements(RequirementsMode =
AspNetCompatibilityRequirementsMode.Allowed)]
public
class
Service1
{
[
OperationContract]
public
DataTable GetActivePatient(string
Role, int RoleIdentity)
{
Database db =
DatabaseFactory.CreateDatabase("ConnectionString");
DbCommand dbCommand = db.GetStoredProcCommand("[GetActivePatients_ByRole]");
db.AddInParameter(dbCommand,
"@Role",
DbType.AnsiString, Role);
db.AddInParameter(dbCommand,
"@RoleIDentity",
DbType.Int32, RoleIdentity);
try
{
DataSet dataSet = db.ExecuteDataSet(dbCommand);
return dataSet.Tables[0];
}
catch (Exception)
{
return
null;
}
}
using this wcf i m getting patient list which is stored in my Database.
On page.xaml.cs i have used this service to fill datagrid i.e Acptlist
private
void AcPtlist_Loaded(object
sender, RoutedEventArgs e)
{
Tab.ServiceReference1.
Service1Client WebServices =
new Tab.ServiceReference1.Service1Client();
WebServices.GetActivePatientCompleted +=
new
EventHandler<Tab.ServiceReference1.GetActivePatientCompletedEventArgs>(WebServices_GetActivePatients);
WebServices.GetActivePatientAsync(
"Hospitalist", 3);
}
public
void WebServices_GetActivePatients(object
sender, Tab.ServiceReference1.GetActivePatientCompletedEventArgs e)
{
AcPtlist.ItemsSource = e.Result;
}
but it gives error that Error 1 Cannot implicitly convert type 'Tab.ServiceReference1.GetActivePatientResponseGetActivePatientResult' to 'System.Collections.IEnumerable'. An explicit conversion exists (are you missing a cast?)
can anyone help me.
Thank u
Sudhir
