Hi Barry,
   Thank you for your reply, Now i sending my sample please check it once and suggest me.
MainWindow.xaml.cs
private void Save_Click(object sender, RoutedEventArgs e)
 List<CustomerMainViewModel> customer = new List<CustomerMainViewModel>(); customerviewmodel.NameTextField = tbName.Text;
customerviewmodel.AddressTextField = tbAddress.Text;
customerviewmodel.CountryField = countryddl.Text;
customerviewmodel.StateField = stateddl.Text;
customerviewmodel.Product = customerviewmodel.Product1 + "," + customerviewmodel.Product2;
foreach(string str in customerviewmodel.actionCollection)
customerviewmodel.ActionColl.Add(str);
customerviewmodel.actionCollection.Clear();
customer.Add(customerviewmodel);
dataGrid1.Items.Add(customer);
MessageBox.Show("Data Successfully Saved", " MessageBox", MessageBoxButton.OK, MessageBoxImage.Asterisk);
clearValues();
MainWindow.xaml
<DataGrid
Height="144"
HorizontalAlignment="Left"
Margin="79,447,0,0"
Name="dataGrid1"
VerticalAlignment="Top" CanUserAddRows="True"
Width="399" Grid.RowSpan="2" IsReadOnly="False">
<DataGrid.Columns>
<DataGridTextColumn Header="NAME" Binding="{Binding NameTextField,Mode=TwoWay}" Width="Auto" IsReadOnly="False" />
<DataGridTextColumn Header="ADDRESS" Binding="{Binding AddressTextField,Mode=TwoWay}" Width="Auto" IsReadOnly="False"/>
<DataGridTextColumn Header="GENDER" Binding="{Binding GenderField,Mode=TwoWay}" Width="Auto" IsReadOnly="False"/>
<DataGridTextColumn Header="COUNTRY" Binding="{Binding CountryField,Mode=TwoWay}" Width="Auto" IsReadOnly="False"/>
<DataGridTextColumn Header="STATE" Binding="{Binding StateField,Mode=TwoWay}" Width="Auto" IsReadOnly="False"/>
<DataGridTextColumn Header="PRODUCT" Binding="{Binding Product,Mode=TwoWay}" Width="Auto" IsReadOnly="False"/>
<DataGridTemplateColumn Header="ACTION" MinWidth="140" IsReadOnly="False">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<ComboBox x:Name="actionddl" ItemsSource="{Binding ActionColl}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
In the above "xaml" file i am using the attribute "Readonly="False"" but its not effected on my code still my datagrid is in readonly mode, i don't know why it happens. 
And I am adding data to my datagrid through "Wpf controls (TextBox,CheckBox,ComboBox and etc...)"  while click on "save" button the data added to grid. adding to grid works properly but the entire row is in readonly mode. How can
i solve my problem.
