Passing value from one form to another

hi,

you can use constructor to pass value from one page to another page if you are working with windowbase application.

public Form2(int mydata)
{
  // do some thing...
}

private void button1_Click(object sender, EventArgs e)
{
 int data = 5;
 Form2 f = new Form2(data);
 f.show();
}

you can use any state Management technique like viewstate, session Query string etc if you are working on web base application

hope this will help you.
