how to refresh a datagrid in c# wpf frequently

Question

I made a data grid using wpf,c#. A separate window is used to insert data into data grid .After clicking save button the data grid is not updating .If we close or refresh the window the grid will update.

        <DataGrid x:Name="dgTrnDetails"  AutoGenerateColumns="False"  IsReadOnly="True"  HorizontalAlignment="Left" Margin="227,124,0,0" VerticalAlignment="Top" Height="380" Width="1104"  >

            <DataGrid.FontSize>
                16
            </DataGrid.FontSize>
            <DataGrid.FontFamily>
                <FontFamily>Arial</FontFamily>
            </DataGrid.FontFamily>
            <DataGrid.Columns>
                <DataGridTextColumn Header="TRN Number" Binding="{Binding TRNNO}"/>
                <DataGridTextColumn Header="Supplier" Binding="{Binding Supplier}"/>
                <DataGridTextColumn Header="Customer" Binding="{Binding Customer}"/>
                <DataGridTextColumn Header="Vehicle" Binding="{Binding Vehicle}"/>
                <DataGridTextColumn Header="Driver" Binding="{Binding Driver}"/>
                <DataGridTextColumn Header="Status" Binding="{Binding Status}"/>
                <DataGridTemplateColumn>
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <Button x:Name="AddButton" Content="Edit" Click="btnEditTrn_Click"></Button>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>

To get the grid refreshed immediatly, you need to modify the data structure the grid is bound to. Probably an event aggregator would be usefull — Jesús López, Feb 11 '15 at 06:44
how do you insert data? binding or Items.Add()? please add some of your code — Bizhan, Feb 11 '15 at 07:03
You definitely want to bind your data. use an observable collection. — Bizhan, Feb 11 '15 at 07:25

You have to define a closed event for your seperate window as you can see in that link

Then in the closed event you need to do that:

dgTrnDetails.ItemSource = yourItemSource;
