Hello all,

How can I store the value of the variables which are under Button_Click event, so that I can use that value again for another Button_Click event ?

Have you tried sessions?

That depends on the environment you are in.
The procedure for WinForms is very different from the procedure for a web site.

For WinForms, all you need to do is move teh definition to class level, so it is not within the click event handler:

C#

private int myInt = 6;
private void myButton_Click(object sender, EventArgs e)
    {
    myInt++;
    }

For Web, it is a bit more complex, because class variables are not maintained after a page is loaded to the client (and they will all be reset before a post back). In this case, use the Session:

C#

   int myInt = Session["MyInt"];
...
   myInt++;
...
   Session["MyInt"] = myInt;

Solution 2

C#

   // one button click
Session["op1"] = op1;
Session["op2"] = op2;
Session["op"] = op;

//another button click event
op1 = int.Parse(Session["op1"].ToString());
            op2 = int.Parse(Session["op2"].ToString());
            op = Session["op"].ToString();
