Radio button with gridview asp.net

Hi Ther,

We are facing many problems with including radio button with grid
one of them is all are selected because they are generating different name in html
to overcome we have to do the following then its easy.

in html code we have to assign its checked chang event and in code back we have to write the code like this

     foreach (GridViewRow row in gridViewProducts.Rows)
   {
    ((RadioButton)row.FindControl("radioButtonToSelectTheProductResult")).Checked = false;
   }
   var radioButton = (RadioButton)sender;
   radioButton.Checked = true;

then what we are doing here is setting first all check box to false and then the one who is sender to true.

by default with radio we are giving customer to select one, we are not allowing to deselect all.
so one who is clicked is already selected in grid.

It is working correctly there.

Engjoy radiobutton with gridview

Thanks & Regards

Inheritance


When we are calling the object of child class. always constructor of base class calls the first

In desctructor it is always first desctuct the child object than parent

A a2 = new B();      allowed

but we can not give reference of parent to child.


as int are structs and cannot have reference to object
int is using IEquatable interface to implement
which contains Equals method through which int can chek equality comparison there.

***************************************
namespace Test2
{
 public class A
 {
  public A()
  {
   Console.WriteLine("This class A");
  }
 }
 
 public class B : A 
 {
  public B()
  {
   Console.WriteLine("This class B");
  }
 }
 
 
 public class C : B
 {
  public C()
  {
   Console.WriteLine("This class C");
  }
 }
}




namespace Test2
{
 class Program
 {
  static void Main(string[] args)
  {
   A a = new A();
   System.Console.Read();
   B b = new B();
   System.Console.Read();
   C cC1 = new C();

Updating multiple rows from trigger byy inserted table

Hi All
Many times we are facing that we need to change the value of Column1 of Table2 when Table1 updates.

This below is given solution by- Nipam Budhabhatti
So we need trigger.
We can either select value in some variable.
but it has problem that we cannt update all rows.
so this is the solution
by implementing it we are sure that all records in Table2 are updated after updating table1.

CREATE TRIGGER [TrgName] ON Table1
FOR UPDATE
AS
UPDATE Table2
SET
Column1 = INSERTED.Column2
FROM INSERTED
WHERE
Column3 = Column4

Explicit implement interfacess

Hi All

when we are explicitly implementing interface like..
if we have 2 interfaces which has same method; one class implements both,
then in derivced class we can not use public as access modifier to those implemented methods.

2 solve this i think we can create one wrapper method.
that method checks the type od object and according to type it will execute the method from those implemented.

I think this will help us to understand the working of interface little more.
