c# - Form Not getting Closed Completely while using "this.Close()" -

i'm using visual studio 2010 , i'm troubling problem in project right . question may feel foolishness . don't know happening.

in project there 3 forms .

• form1
• form2
• displayfrm

i trying open form(displayfrm) using 2 other forms(form1 , form2)

this code used open "displayfrm" using both "form1" , "form2"

        displayfrm.initialloadcustprof = regcustidtextbox.text;         displayfrm frm = new displayfrm();         frm.showdialog(); 

• i have opened "displayfrm" using from1
• after doing operations on there have closed form using [x] button in title bar.
• (also have tried giving this.close(); in separate button)

the problem ,when opening displayfrm agian using form2 ,it's not starting fresh form . restoring displayfrm have closed before operations have done already.

• i don't have trouble other project . think project crashed ..it not showing kind of error.
• is there way use this.dispose(); form closing event?.currently not working fine .
• why form not getting closed ? . why behaving have used this.hide(); , this.show(); ?

displayfrm.initialloadcustprof seems static. try change instance property , open form this:

using( displayfrm frm = new displayfrm() ) {     frm.initialloadcustprof = regcustidtextbox.text;     frm.showdialog( ); }
