How to Display and select items in a Datagrid Comb

I want to be able to choose either "true" or "false"(boolean) from a ComboBox that is within a wpf Datagrid and be able to save that choice to my database.

I want to be able to indicate inside of a column if the row is "Active" or not through a boolean variable saved to my database as a bit(1 = true; 0 = false).

Here is my create table statement: Create Table Statement(AccountType)

I populate the datagrid using an ObservableCollection as follows:

protected override void Get()
{
    using (var dbContext = new IEMASEntitiesDataContext())
    {
        var accountType = from s in dbContext.AccountTypes select s;
        var observable = new  ObservableCollection<AccountType>(accountType);

        Collection = observable;
    }
}

My XAML code is as follows:

<DockPanel DataContext="{StaticResource ResourceKey=AccountTypeViewModel}" LastChildFill="True">
    <ToolBar DockPanel.Dock="Top">
        <Button Content="Display"  Command="{Binding GetCommand}" Width="78"/>
        <Button Content="Save" Command="{Binding SaveCommand}" Width="78"/>
    </ToolBar>

    <Grid>
        <GroupBox x:Name="AccountTypeGroupBox">
            <DataGrid x:Name="DataGridAccountType" ItemsSource="{Binding Collection}" AutoGenerateColumns="False">
                <DataGrid.Columns>
                    <DataGridTextColumn  Header="AccountType" Width="150" Binding="{Binding Path=AccountTypeName, Mode=TwoWay, NotifyOnSourceUpdated=True, UpdateSourceTrigger=PropertyChanged}"/>
                    <DataGridComboBoxColumn  Header="Active" Width="100" SelectedValueBinding="{Binding StatusList, UpdateSourceTrigger=PropertyChanged}" SelectedValuePath="AccountTypeId" DisplayMemberPath="Active"/>                   
                    <DataGridTemplateColumn Width="50" Header="Delete">
                        <DataGridTemplateColumn.CellTemplate>
                            <DataTemplate>
                                <Button x:Name="btnDelete" Content="Delete" Command="{Binding DeleteCommand}"/>
                            </DataTemplate>
                        </DataGridTemplateColumn.CellTemplate>
                    </DataGridTemplateColumn>
                </DataGrid.Columns>
            </DataGrid>
        </GroupBox>          
    </Grid>
</DockPanel>

It doesn't work. Nothing displays within the comboboxes, and I don't know how to save the selected item to the SQL Server database when it does display. I'd appreciate some help, please. I am using LINQ TO SQL. I am a newbie :-(.

As I can understand the problem is how to bind some XAML resource as a combo ItemsSource and in addtion how to binnd the selected value of a combo to the model behind the DataGrid row. 1. List item:

DataGrid viewmodel:

```
}

public ObservableCollection<UserData> Collection { get; set; }
```
}

Models: public class UserData : BaseObservableObject { private string _uName; private object _countryData; private bool _isActive;

public bool IsActive

    get { return _isActive; }
    set
    {
        _isActive = value;

public Country() { }
public Country(string n, string d)
{
    this.CountryName = n;
    this.CountryPop = d;
}

} Hope it will help you.
