I have a button on form.I have implemented button_click event for the button as follows
protected void button_Click(object sender,EventArgs e)
//i did following operation
// update salarytbl set salary=salary+1000
Here if i click button it will fire click event and update salary say salary is 500 then updated will be 1500
but now when i click refresh button again salary is updated to 2500, again i click refresh salary is 3500.. it goes
ie button click is fired when i say refresh.
