Trying to auto-resize a winforms button, within another control

Question

As the title states, i have a button anchored to the lower right of a control in the designer. Setting the button to autosize does not change the button's size when the form is resized, furthermore, it is eventually swallowed by the rest of the control. Is there a standard setting in designer that allows the button to resize when the control it is part of, resizes? If it must be done programmatically, how is that done? Thank you.

Hi @nope no ,

You can use the SizeChanged event to automatically size other controls.

The following code uses Form1_SizeChanged as an example to keep the button1 automatically scaled in equal proportion to Form1.

        float firstWidth;
        float firstHeight;

        private void Form1_SizeChanged(object sender, EventArgs e)
        {
            float size1 = this.Size.Width / firstWidth;
            float size2 = this.Size.Height / firstHeight;

            SizeF scale = new SizeF(size1, size2);
            firstWidth = this.Size.Width;
            firstHeight = this.Size.Height;

            button1.Font = new System.Drawing.Font(button3.Font.FontFamily, button3.Font.Size * ((size1 + size2) / 2));

            button1.Scale(scale);
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            firstWidth = this.Size.Width;
            firstHeight = this.Size.Height;
        }

Best Regards.
