Bind List to DataGrid

I have a problem binding a List to a DataGrid in WPF. Let me explain what I have tried.

public struct SomeInfo
{
    public string Name;
    public string Description;
    public string ID;
}

List<SomeInfo> arrSomeInfo;

The arrSomeInfo contains multiple items of structure SomeInfo.

The DataGrid Looks something like:

<DataGrid Name="grdMailbag" AutoGenerateColumns="False" ItemsSource="{Binding}">
    <DataGrid.Columns>
        <DataGridTextColumn x:Name="cID" Binding="{Binding ID}" Header="ID" />
        <DataGridTextColumn x:Name="cName" Binding="{Binding Name}" Header="Name" />
        <DataGridTextColumn x:Name="cDescription" Binding="{Binding Description}" Header="Description" />
    </DataGrid.Columns>
</DataGrid>

I have tried the following without success:

this.grdMailbag.ItemsSource = arrSomeInfo; //Didn't worked
this.grdMailbag.DataContext= arrSomeInfo;  // Didn't worked

What is happening is that it is adding the rows as per List arrSomeInfo but all the rows are blank.
