Please find the Xaml code below
<
telerik:GridViewComboBoxColumn UniqueName="Report Type Code" Header="Report Type Code" Width="100" SelectedValueMemberPath="Value" DisplayMemberPath="Text" x:Name="GridViewDataColumn30" DataMemberBinding="{Binding Path=ReportTypeCode, Mode=TwoWay,ValidatesOnDataErrors=True,ValidatesOnExceptions=True,NotifyOnValidationError=True}" ItemsSource="{Binding Path=ASIReportTypeCode.resConceptCodes, Source={StaticResource DC_ServiceLevelVM}}">
</telerik:GridViewComboBoxColumn>
ASIReportTypeCode.resConceptCodes is the collection which gets filled asynchronously from WCF Service.
In the View model.cs file
I have tried to fill the
ASIReportTypeCode.resConceptCodes from the InitializeAction method using a component which will post the request to the WCF service.
