How to bind the same collection of values into all ComboBoxes in a DataGridComboBox?

[Miguel RBR]

I have a Collection of Values in an Array of Strings, or in a List or whatever, and what i want is to set this Collection of values as the Collection of items into all the ComboBoxes in a column as DataGridComboBox in WPF.

I think i don't have other way to access this Collection of Values and bind it equally to all the ComboBoxes (in XAML) beside the DataContext. But can i access the DataContext of a DataGrid from a DatGridComboBox Column (in XAML)? Can i do it? How?

How i set (in XAML) in DatagridComboBox to put this Collection of Items equally in all ComboBoxes? How i can achieve this?


Here is my XAML:

<Grid Name="grid1">
    <DataGrid Name="dataGrid" AutoGenerateColumns="True">
        <DataGrid.Columns>
            <DataGridComboBoxColumn Header="Options" Width="100" ItemsSource="{Binding RelativeSource={RelativeSource AncestorType=DataGrid}, Path=DataContext}"/>
        </DataGrid.Columns>
    </DataGrid>
</Grid>

And here is my Code Behind:

public MainWindow()
{
  InitializeComponent();
 
  string[] abc = {"10", "20", "30", "40", "50"};
 
  dataGrid.DataContext = abc;
}

        <DataGrid.Columns>
            <DataGridComboBoxColumn Header="Options" Width="100"/>
        </DataGrid.Columns>

</Grid>
 

And here is my Code Behind:

public class TestClass
{
    private static string[] stringArray = { "Option One", "Option Two", "Option Three" };
 
    public static string[] StringArray
    {
        get
        {
            return stringArray;
        }
    }
}
