Question

I have a button that on click I would like to be disabled and it’s background image to be changed to null here is the code I have that happens on button click

    private void levelOne1001_Click(object sender, EventArgs e)
    {
        levelOne1001.Enabled = false;
        levelOne1001.BackgroundImage = null;
        scoreClass.genRandomNumber(100);
        scoreClass.valOfQuestion = 100;
        q1001 = true;
        openQuestionForm();
    }

And here is the code from openQuestionForm();

    private void openQuestionForm()
    {
        QuestionForm qForm = new QuestionForm();
        scoreClass.iCount++;
        qForm.Show();
        this.Hide();
    }

And here is where I call this form back up

     Level1Form l1Form = new Level1Form();
     l1Form.Show();

How the process works is Button on Original form is clicked goes to a Question form, button on Question form is clicked it goes back to Original Form. But when I go back to the original form the button is still enabled and the image is still there. Is there any way to fix this?

EDIT: Forgot to say this was in WinForms

Answer 1

You are instantiating a new Level1Form, so it’s returning to its default state, causing the button to return to its default state. There are a few possible approaches:

Add a parameter to Level1Form’s constructor that indicates what state the button should be in, something like

 Level1Form(bool enableButton) {
     initComponent();

     if(!enableButton) {
         levelOne1001.Enabled = false;
         levelOne1001.BackgroundImage = null;            
     }
  }

Or, grab the same form again and reuse it. You will need to keep a reference to it somewhere and tell it to show itself again. Alternately, you can grab it out of Application.OpenForms
