Custom groupbox control not painting correctly when added to tabpage

I have a groupbox which I created a custom paint event for so that I
can control the border color.
It works great when the groupbox is on a form but when the groupbox is
on a tabpage, the control does not paint properly. Everything is blurry
and the child controls inside the groupbox are also blurry and get a border
drawn.
Any gentle help would be greatly appreciated!
Thanks,
Dan

How Can I input the value of a Visual c# track bar into a pen size value?

How would I input a trackbar.Value into a value for a Pen? I am trying to take the value of trackBarSize and put in for an integer value, is this possible?
On line
Pen myPen = new Pen(Color.Black, trackBarSize.Value);
I got this error:
CS0236 C# A field initializer cannot reference the non-static field, method, or property 'WhiteBoard.trackBarSize'
What would i have to do in order to get the value of the trackbar to be the value of the brush size?
If you want all of the values for each object, I can provide it.

In this declaration line:
Pen myPen = new Pen(Color.Black, trackBarSize.Value);
You can't use trackBarSize.Value because the control hasn't even been created and initialized yet.
So simply pick a default size and use that:
Pen myPen = new Pen(Color.Black, 1);
Then, in the ValueChanged() event of your TrackBar, you'd update the Width property of your Pen:
private void trackBarSize_ValueChanged(object sender, System.EventArgs e)
{
myPen.Width = (Single)trackBarSize.Value;
}

Winforms DataGridView resizing issue

I'm not 100% sure how I should word this question but I'll try my best.
I have a PointCtrlForm that has a DataGridView inside a TableLayoutPanel. The DataGridView is docked to the table as Fill. PointCtrlForm is docked to another window set as MDIParent with the dockstyle property set as Fill.
Resizing the main window properly resizes the PointCtrlForm, which then is supposed to resize the DataGridView as well. Well, at least "half" of the resizing works properly. Enlarging the main window also enlarges the datagridview, which is what I expected but if I shrink the main window to a certain point, the DataGridView stops shrinking and hides the columns without showing a scrollbar.
I've checked that all columns do not have Frozen property enabled, checked that both the datagridview and the child window is properly docked, and checked the scrollbars property is set to both.
Edit: AutoSizeColumnsMode is also fill.
I'll post the content of the Designer.cs here. I'd appreciate any guidance.

I've found the solution and it's rather simple.
The row and column sizes for the DGV has to be set "percentage (relative)" not "absolute" in order for the docking to work properly.
You can edit the sizes by right clicking on one of the cells of the DGV and clicking on Edit Row/Column Properties.

How to create tables in windows form application?

How do you create a table in winforms where individual cells can look like this:
I have been using a tablelayoutpanel, but it only lets you but one control per cell. Any ideas?

The only way to emulate this is to use nested tablelayoutpanels.
To get your desired output in the example:
TableLayout1: 1 Row, 2 Columns
TableLayout2 goes within column2 of TableLayout1: 3 Rows, 1 Column

There is ALWAYS a way to get it to work. It may not be obvious from the WinForms designer, but it is not too hard.
Try this:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;

I noticed that artefacts appeared only when draw near the borders of picturebox.
I don't agree that is border-artefacts.
Temporary (approximately for 100 years :) solved with this hack
pictureBox.Location = new Point(-1, -1);
int delta = 2;
int paintWidth = pictureBox.Width - delta;
int paintHeight = pictureBox.Height - delta;
...
points[0] = new PointF(hLenL + delta, paintHeight);
points[1] = new PointF(paintWidth - hLenR, paintHeight);
points[2] = new PointF(paintWidth, delta);
points[3] = new PointF(delta, delta);
