The following example demonstrates how to bind a grid to an array defined in the resources of the containing grid.

XAML
Copy Code 
<Grid xmlns:s="clr-namespace:System;assembly=mscorlib"

      xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">                     

  <Grid.Resources>

  <x:Array x:Key="data_list" Type="{x:Type s:String}">

    <s:String>Sunday</s:String>

    <s:String>Monday</s:String>

    <s:String>Tuesday</s:String>

    <s:String>Wednesday</s:String>

    <s:String>Thursday</s:String>

    <s:String>Friday</s:String>

    <s:String>Saturday</s:String>

  </x:Array>

  </Grid.Resources>

  <xcdg:DataGridControl x:Name="OrdersGrid"

                        ItemsSource="{StaticResource data_list}"/>

</Grid>
VB.NET
Copy Code 
Dim data() As New String( 6 )

data( 0 ) = "Sunday"

data( 1 ) = "Monday"

data( 2 ) = "Tuesday"

data( 3 ) = "Wednesday"

data( 4 ) = "Thursday"

data( 5 ) = "Friday"

data( 6 ) = "Saturday"

dataGridControl.ItemsSource = data
C#
Copy Code 
string[] data = new string[ 7 ];

data[ 0 ] = "Sunday";

data[ 1 ] = "Monday";

data[ 2 ] = "Tuesday";

data[ 3 ] = "Wednesday";

data[ 4 ] = "Thursday";

data[ 5 ] = "Friday";

data[ 6 ] = "Saturday";

dataGridControl.ItemsSource = data;
