C# Get information from a form (Like MessageBox buttons just with a form made by me)

Question

recenntly I've been working on a painting software,
and i need to get information from a sub-form that contain's 3 controls:

• TextBox1 - a TextBox
• OkButton - a Button
• CancelButton - a Button

the main form contains 2 controls:

• Label1 - a Label
• ChangeLabel1TextButton - a Button

That sub-form need to be shown when i press the "ChangeLabel1TextButton" button on my main-form,
than, when you press the "OkButtom" on the sub-form,
the main form need's to set "Label1" text to the text of "TextBox1" textbox on the sub-form.

Images of the forms:

Hope you could help me!
Thanks anyway : )

Answer 1

To get you started,

1. In your sub-form, create a public property (let's call it InputText) that returns the text of the textbox.
2. In your main-form, open the sub-form (.ShowDialog())
3. After the sub-form has closed (close it when OK is pressed), use the new property (InputText) to get the text and set to your label.Text.
4. Done!
