Getting error in implementing form resize in a winform app using krypton toolkit..

Question

I have created a windows form application using Krypton toolkit Krypton which has its controls like combo box, datagridview, buttons etc. I basically want the controls to resize accordingly when the main form is resized so that no control gets hidden or unreadable etc.

using ComponentFactory.Krypton.Toolkit;
using System.Globalization;
using System.IO;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;

namespace Wiz
{
 /// <summary>
 /// Description of MainForm.
 /// </summary>
 public partial class MainForm : KryptonForm
 {
 private float firstWidth;
 private float firstHeight;

 public MainForm()
 {

 InitializeComponent();

 }

 void KryptonButton4Click(object sender, EventArgs e)
 {
 Application.Exit();
 }
 void MainFormLoad(object sender, EventArgs e)
 {
 firstWidth = this.Size.Width;
 firstHeight = this.Size.Height;
 }
 void KryptonButton1Click(object sender, EventArgs e)
 {

 }
 void KryptonButton2Click(object sender, EventArgs e)
 {

 }
 void KryptonDataGridView1SelectionChanged(object sender, EventArgs e)
 {

 }
 void KryptonDataGridView2SelectionChanged(object sender, EventArgs e)
 {

 }
 void KryptonButton6Click(object sender, EventArgs e)
 {

 }
 void KryptonButton5Click(object sender, EventArgs e)
 {

 }
 void KryptonButton3Click(object sender, EventArgs e)
 {

 }

 private void MainForm_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;

 foreach (Control control in this.Controls)
 {

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

 control.Scale(scale);


 }

 }
 }
}

Now, when I run the app I get the below error:

************** Exception Text **************
System.ArgumentException: Value of 'Infinity' is not valid for 'emSize'. 'emSize' should be greater than 0 and less than or equal to System.Single.MaxValue.

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)

I cannot figure out how to solve this. Can anyone help?

@don bradman , We noted that krypton toolkit is a 3rd party product and it is not supported in Micrsoft Q&A. You can ask the question in Github-issues
