c# winform Resizing button on different form

Question

I want to resize my button on form2 using the button on form1 .

This is my code and it gives me error:

public void button7_Click(object sender, EventArgs e)
{
    Form2 f2 = new Form2();
    int x = Convert.ToInt32(textBox7.Text);
    int y = Convert.ToInt32(textBox8.Text);
    f2.button8.Size = new System.Drawing.Size(x, y);
}

It has an error at Form2.button8.Size .. I made my button8 Public so it can be accessed.. but still it gives me error "Form2.button8 is inaccessible because of its protection level" ..

this is my button8 at form2

public void button8_Click(object sender, EventArgs e) { }

How can I solve this issue?

Answer 1

namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
    Form2 f2 = new Form2();

    public Form1()
    {
        InitializeComponent();
        f2.Show();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        f2.button1.Size = new Size(int.Parse(textBox1.Text), int.Parse(textBox2.Text));
    }
}
}

I made button1 on the form2.designer.cs internal.

namespace WindowsFormsApplication2
{
    partial class Form2
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.button1 = new System.Windows.Forms.Button();
            this.SuspendLayout();
            // 
            // button1
            // 
            this.button1.Location = new System.Drawing.Point(95, 89);
            this.button1.Name = "button1";
            this.button1.Size = new System.Drawing.Size(75, 23);
            this.button1.TabIndex = 0;
            this.button1.Text = "buttonForm2";
            this.button1.UseVisualStyleBackColor = true;
            // 
            // Form2
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(284, 262);
            this.Controls.Add(this.button1);
            this.Name = "Form2";
            this.Text = "Form2";
            this.ResumeLayout(false);

        }

        #endregion

    //This is where you change from private to internal
        internal System.Windows.Forms.Button button1;
    }
}
