Reload the main form from childform

It gives some errors. It is not working.

Hi Mehmet

In the main form, create a public method or property that allows other forms to update the image. For example, you can create a method called UpdateImage that takes an image as a parameter and updates the image in the panel.

public void UpdateImage(Image newImage)
{
    panel2.BackgroundImage = newImage;
}

In the subform, add a reference to the main form so that you can access its public methods and properties. You can achieve this by passing the instance of the main form to the constructor of the subform.

private MainForm mainForm;

public SubForm(MainForm mainForm)
{
    InitializeComponent();
    this.mainForm = mainForm;
}

private void buttonChangeImage_Click(object sender, EventArgs e)
{
    // Perform image selection logic, e.g., using OpenFileDialog
    Image newImage = GetSelectedImage();

    // Call the UpdateImage method in the main form to update the image
    mainForm.UpdateImage(newImage);
}

hope this helps
