Question

Visual Basic

How to highlight all textbox in windows form? And here, for example, you type text into the textbox after pressing enter or moving to another field, a checkmark is displayed, how to write it in one line, otherwise you don’t want to write like this:
textbox1 = picturebox1.visible = true
textbox2 = picturebox2.visible = true
.. .textbox
(i++) = picturebox(i++).visible = true

Answer 1

Example:

var textBox = this.Controls["textBox1"] as TextBox; // где textBox1 - это свойство Name текстбокса
textBox.Hide();

It seems to be enough to understand the logic.
The textbox in this case should lie directly on the form. If in the panel, then you need panel1.Controls
