hi Parthiban keep your form1 object alive because every time you create new instance of form1 the page(form1) will be refresh. so try this... form1 frm; //globally in the event where you want to open form1 first check whether form1 object is null or not If is null then create an instance of it else show the form as it is using show() method if(frm == null) { frm = new form1(); } frm.show(); hope this helps you....
