Hi All,

I am having this issue and don't really know a good way to overcome it. I have a main form. With a click of a button another form is created. For the example let's just say it has a simple text box. You type whatever you want in it.

My problem arises is how do I get the string from that child class to the calling class.


So what I would like to know is a a good solution for when the child form closes it can somehow pipe back information to the parent class. I tried doing some research and a delegate kept popping in my head but through frustration couldn't get them working. So is a delegate a good solution for this or am I completely missing something.

I give an alternative to do so:
First:
Create a class in witch u create a static string variable
Here is the procedure:
first step:

public class Variables
{
public static string myVariable ="";
}

Second step:
In the event handler ChildForm_Formclosing(object sender, EventArgs e)
implement it as follow
ChildForm_Formclosing(object sender, EventArgs e)
{
Variables.MyVariable=TextBox.Text.ToString();
}

Third step:
In the Main form

//define an instantiate a new ChildForm
ChildForm oChildForm = new ChildForm();
//Add a new event
oChildForm.FormClosing+= new EventHandler(ChildForm_FormClosing)
{
TextBox1.Text = Variables.MyVariable;
}

Ok, sounds simple but how about a child form having a read only property that can hold a string.
Once the child form closes, this property should still be available immediately after.

change

this.ChildClass = new TextboxForm();
this.ChildClass.Show();
to

this.ChildClass = new TextboxForm();
this.ChildClass.ShowDialog(this);

Thanks All!
