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

Question

I'm Using Visual Studio 2010 And I'm troubling with a problem in my project right now . this question you may feel like foolishness . But i don't know what happening.

In my Project there are 3 forms .

• Form1
• Form2
• DisplayFrm

I was trying to Open a form(DisplayFrm) using two Other forms(Form1 and Form2)

This is the code That i used to open the "DisplayFrm" using Both "Form1" and "Form2"

        DisplayFrm.InitialLoadCustProf = RegCustIDtextBox.Text;
        DisplayFrm frm = new DisplayFrm();
        frm.ShowDialog();

• I have Opened "DisplayFrm" Using From1
• After Doing some Operations Over there I have Closed that Form using [X] button in Title bar.
• (Also i have tried by giving this.Close(); in a separate button)

The problem is that ,when i am opening DisplayFrm agian using Form2 ,it's not starting as a fresh form . it simply restoring the DisplayFrm which i have already Closed Before with the Operations i have done Already.

• I don't have this trouble with any other project . I think my project crashed ..it does not showing any kind of error.
• is there any way to use this.dispose(); with form Closing event?.Currently that not working Fine .
• Why my Form is not Getting Closed ? . Why it is behaving like i have used this.hide(); and this.show(); ?

Answer 1

DisplayFrm.InitialLoadCustProf seems to be static. Try to change it to an instance property and open the form like this:

using( DisplayFrm frm = new DisplayFrm() )
{
    frm.InitialLoadCustProf = RegCustIDtextBox.Text;
    frm.ShowDialog( this );
}
