<dxg:GridControl AutoGenerateColumns="AddNew"
                 EnableSmartColumnsGeneration="True" 
                 AutoGeneratingColumn="grid_AutoGeneratingColumn"
                 ItemsSource="{Binding Items}">
    <!--...-->
</dxg:GridControl>

C#
VB.NET

csharp

private void grid_AutoGeneratingColumn(object sender, DevExpress.Xpf.Grid.AutoGeneratingColumnEventArgs e) {
    if (e.Column.FieldName == "IsSelected") {
        e.Cancel = true;
    }
}

Private Sub grid_AutoGeneratingColumn(ByVal sender As Object, ByVal e As DevExpress.Xpf.Grid.AutoGeneratingColumnEventArgs)
    If e.Column.FieldName = "IsSelected" Then
        e.Cancel = True
    End If
End Sub
