(finally i got the answer after breaking my head for one day

You need to add property for each varibales in the class property_details as get and set , then it will update in Xaml file during run time similar to below, refer firstname in the XAML file rather than fname ,
class My_class

Public fname As String
Public lname As String

Public Property firstname As String

Get
Return fname
End Get
Set(ByVal value As String)
fname = value
End Set
End Property

Public Property lastname As String

Get
Return lname
End Get
Set(ByVal value As String)
lname = value
End Set
End Property

End Class 'MyClass

Hi Monoj,

This is right. You can't assign a variable for this. You must have to implement it as a Property to the class & then you can do this.

If you want to bind it in the XAML & not from the code behind, you have to create DependencyProperty instead of normal Property.

Let me know, if you need more info on DependencyProperty & data binding.
