Button access from other form

[amitairoa]

Hi!

I have a program in C# which has two forms.

I would like to put a button on Form1, and then the user can change

the button's settings On Form2.

The problem is- how do I access the button that's on Form1- from Form2?

On Form1- the code is:

Button Button1 = new Button();

On Form2- for instance- the user can choose the buttons text- and write it in a textbox on that form. When the user clicks ok- I want to implement the text written in the textbox on Form2- to button1- on Form1.

How do I do this when the button is on the other form?

Please help.

Thanks!

You have a couple of options -- if you want the changes to presist through sessions of your application you'll want to save to a text/xml/database file when the users changes settings on Form2; in order to load those settings you could use a FileSystem watcher and look for changes to your config file.

 

Another approach would be to add an overloaded constructor for Form2 that accepts a reference of Form1 which contains your button [you would need to declare the button as Public] then, you have full access to all properties of Form1 [including the button] from the context of Form2

 

Form1 Code

....
public Button button1 = new Button(...);
....
void LoadUpForm2()
{
   Form2 f = new Form2(this);
   f.Show();
}

 

Form2 Code

Form1 theMainForm
void Form2(Form1 mainForm)
{
   theMainForm = mainForm;
}

protected void textBox1_TextChanged(...)
{
   theMainForm.button1.Text = textBox1.Text;
}

 

I didn't run that through the compiler, but it should get you started.
