accessing controls on parentform from childform

I have parent form form1 and child form test1 i want to change label text of parent form from child form in my parent form i have method to showresult()

public void ShowResult()
{ label1.Text="hello"; }

I want to change label.Text="Bye"; form my child form test1 on button click event. Please give any suggestions.

Answer 1

when calling the child form, set the Parent property of child form object like this..

Test1Form test1 = new Test1Form();
test1.Show(this);

On your parent form, make the property of your label text like as..

public string LabelText
{
  get
  {
    return  Label1.Text;
  }
  set
  {
    Label1.Text = value;
  }
}

From your child form you can get the label text like that..

((Form1)this.Owner).LabelText = "Your Text";
