Multiple instances of same form are openning at same time. How to prevent it?

Hi
I am developing a windows application in which it contains a grid. on double clicking a row on the Grid it shows all the details about that row in a new form.

If i double click the same row or other row it opens the details of respective row again in a same form.

For this i followed one logic. I take a global variable (public boolean X= false) and i am setting it true when user double clicks a row. I am resetting it in the child form. Here the value is not resetting.

What i want is Is there any mechanism or statements of code to preventing the form from openning more than one form at a time.

Please Help me.

Thanks in Advance.

1. Have a class level form variable
2. In the double click event handler, try something like this

Pseudocode

Code:

---

if ((formVariable == null) || (!formVariable.Created))
{
    // create the form
}

formVariable.LoadData(.....);
formVariable.Show();
formVariable.BringToFront();

I am not sure how you are opening the form to display the row data. I think you should be able to control it the place where you create the form.

Thank You Very Much.

It is working for me.

Once Again Thank You.
