Reg displaying combobox selected item details in datagrid

Hello,

I have combobox to which observable collection is bound. This collection is list of Person objects. Person class has 10 details including name. I display name in Combobox saying DisplayMemberPath=Name.

On selection change of combo, I need to show details of person selected in Datagrid below like age, gender etc.

Iin datagrid, I have datagridTextColumn set to corresponding property of Person class for every property as below.

<DataGridTextColumn Header="Name" Binding="{Binding ElementName=cboBox1, Path=SelectedItem.Name}"

I have above code for all columns bound to different property. But data is not displayed in datagrid on slection change of combo.

Below is my total code.

<Grid>

<ComboBox Height="25" Width="100" Name="cboBox1" DisplayMemberPath="Name" ItemsSource="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=Window}, Path=Persons}" SelectionChanged="cboBox1_SelectionChanged">
            
        </ComboBox>
        <DataGrid Name="dtgrdData" Grid.Row="1" ItemsSource="{Binding ElementName=cboBox1}" AutoGenerateColumns="False">
            <DataGrid.Columns>
                <DataGridTextColumn Header="Name" Binding="{Binding ElementName=cboBox1, Path=SelectedItem.Name}" />
                <DataGridTextColumn Header="Age" Binding="{Binding ElementName=cboBox1, Path=SelectedItem.Age}" />
            </DataGrid.Columns>
        </DataGrid>

</Grid>

Any suggestions please.

Regards,

Harish.
