How to access methods of User Controls passed as parameter to a Constructor

Question

I am passing an instance of UserControl as this to the Constructor of the Class which inherits the Page Class and Itemplate Interface , I am saving the instance of type userControl , Now How can I access the methods of the user Control. For Ex, MyUserControl file name is uc_test and The Class datagridtemplate:Page, Itemplate

My UserControl has partial class name uc_test and have method

public int addtwonumbers()
{
 return 10+20;
}

datadatagridtemplate x = new datagridtemplate(this); //new instance

In the datagridtemplate.cs file :

public datagridtemplate(UserControl uc){}

in In one of method of datagridtemplate class I want to do following

int sum = uc.addtwonumbers();

Now I wanted to access all the methods and properties defined in the uc_test , how can I achieve this ?

Cast the user control to your type in the constructor: `uc = uc as MyType` — Jack Miller, Jul 17 '17 at 17:53
here Mytype is the class file you are referring ? i.e. uc_test ? — user14567, Jul 17 '17 at 17:55
It would be clearer for everyone if you provided a minimal example: https://stackoverflow.com/help/mcve — , Jul 17 '17 at 17:56
I think so, can't tell from what you have posted here. Whatever you defined the class as i.e `public class MyType : UserControl` — Jack Miller, Jul 17 '17 at 17:56
It Says type or namespace could be found (missing directive or assembly reference) , — user14567, Jul 17 '17 at 18:09

My UserControl has partial class name uc_test

As suggested by Jack Miller, cast your generic UserControl reference to the correct type that you created:

uc_test ucTst = (uc_test)uc;
int sum = ucTst.addtwonumbers();

I tried to do it but it says it could not be found, I trying calling the namespace and including in the c# file , but it throws an error. – user14567 Jul 17 '17 at 20:20
