Export to excel show class name - using MVVM

[Yuk]

When we click the export to excel, the file display class name as follows. Any idea?

System.Windows.Controls.ContentControl
MyNameSpace.Model.LoanReport
MyNameSpace.Model.LoanReport
MyNameSpace.Model.LoanReport

We inject MVVM model using MEF

 Sample of gridview xaml

<telerik:RadGridView x:Name="GridLoans" Grid.Row="1" AutoGenerateColumns="False" ShowGroupPanel="False"
                    IsFilteringAllowed="True" FontSize="10" ItemsSource="{Binding LoanListCollection}" d:DesignHeight="300"
                     ShowColumnFooters="True"  IsReadOnly="True" MaxHeight="600"
                                  >
                <telerik:RadGridView.Columns>
                  
                    <telerik:GridViewDataColumn  SortMemberPath="GroupCode" Width="100">
                        <telerik:GridViewDataColumn.Header>
                            <ContentControl>
                                <StackPanel Orientation="Vertical">
                                    <TextBlock Text="Group Id" HorizontalAlignment="Left" />
                                </StackPanel>
                            </ContentControl>
                        </telerik:GridViewDataColumn.Header>
                        <telerik:GridViewDataColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Path=GroupCode}" VerticalAlignment="Center" TextTrimming="WordEllipsis"
                                        HorizontalAlignment="Left" />
                            </DataTemplate>
                        </telerik:GridViewDataColumn.CellTemplate>
                    </telerik:GridViewDataColumn>
    </telerik:RadGridView.Columns>
         </telerik:RadGridView>

  public class LoanReport
    {
        private int Id {get;set;}

        public string GroupCode { get; set; }
    }

 

ViewModel injected with MEF

[PartCreationPolicy(CreationPolicy.NonShared)]
    [Export(Constants.ViewModel, typeof(ViewModelBase))]
    public class LoanReportViewModel : ViewModelBase
    {

 ....

   private ObservableCollection<LoanReport> loanListCollection;

        /// <summary>
        /// Loan Collection
        /// </summary>
        public virtual ObservableCollection<LoanReport> LoanListCollection
        {
            get
            {
                if (loanListCollection == null)
                {
                    loanListCollection = new ObservableCollection<LoanReport>();
                }

                UpdateQuaterPayment(loanListCollection);

                return loanListCollection;
            }

            set
            {
                loanListCollection = value;
               RaiseCollectionChange();
            }
        }

     }

Looks like I need to create the DataMemberBinding

what about the header?

Hi,

 For custom header and templates you can use ElementExporting event and set desired value to e.Value similar to this demo. 

All the best,
