From what I can see here, you haven't assigned the Customer class to the DataContext. Without doing that, your Binding will not work.

Thanks for the reply
DataContext="{Binding Customer}"
inside the DataGrid Tag ?

You mean something like this

<datagrid name="Sampledatagrid" autogeneratecolumns="True" datacontext="{Binding Customer}" itemssource="{Binding CustomerData}" margin="0,0,0,106">

I m sorry .. new to WPF

No - I mean doing something as simple as:
<Window.DataContext>
<local:Customer />
</Window.DataContext>

I think you need to create the List of customers as a class in it's own right like this

C#

public class Customer
    {
        public string Name
        {
            get;
            set;
        }
        public int No
        {
            get;
            set;
        }
        public Customer()
        {
        }
    }
    public class Customers : List<Customer>
    {
        public Customers()
        {
            this.Add(new Customer() { Name = "Adam", No = 1 });
        }
    }

then you can create a Static or Dynamic Resource in your Window and bind to the Resource like this

XML

<Window.Resources>
        <local:Customers x:Key="MyCustomers"/>
    </Window.Resources>

and create your DataGrid like this

XML

<DataGrid Name="Sampledatagrid" AutoGenerateColumns="True" ItemsSource="{StaticResource MyCustomers}" Margin="0,0,0,106"/>

and then you should be able to see your data straight away even in the designer.

This assumes that you have declared your namespace that the Customer class is in and you have called it local like this

XML

xmlns:local="clr-namespace:yourApplication"

Hope this helps
