Access dialog results from the parent form in c#

This is something very important for a developers who is migrating from VB to .NET. Even though this is explainning using C# it is not much ditingush from VB code.

• Lets say you are having two Windows forms called Form1 and Form2 in your project. Form1 will be your parent form and Form2 will be the Dialog form.
• Form1 will have a Command button and a Label control to display the input from the Dialog form(Form2). Dialogform(Form2) will have a textbox and two command buttons.
• In the Form2 change the text properties of two buttons as OK and CANCEL.
  
• Set OK buttons DialogResult property to OK and CANCEL buttons property to Cancel.
• Set Modifier property of the textBox1 in the Form2 to Public or Internal. This will allow the parent form(In this case form1) to access the text value of the dialog form.
  
• Write following code segement on click events of both buttons (Or create one method and change the delegation)

this.Close();

• In the Form1 Command buttons Click event write the following code

Form2 nfrm = new Form2();
if(nfrm.ShowDialog() == DialogResults.OK)
{
this.label1.Text = nfrm.textBox1.Text;
}

• It is pretty simple and if you have any further quetions, corrections, suggetions please contact me.
