Introduction
I wanted to create Custom windows forms in C#. Before working on this code, I started to find any code that could help me to create custom windows forms in C# on the internet. But unfortunately, I couldn't find any simple and useful code. I found some code but they all are complicated. When I started working on solving this problem, I thought to:
- Use Custom Panel/Panel as a border of a Frame for change the size of Form such as Width, Height etc and use Custom Buttons as a Control Box of a Frame.
- Use Custom Panel as a Top layered Title border of a frame and use label to display text of a frame.
- To display icon on a frame we will set background image to added panel.
- Applying Mouse Events to panels and change properties of Form.
And it works perfectly.
You require Visual Studio Professional 2013 or higher version and .NET framework 4.5 or higher to open the project.
Perform following all Steps correctly to create custom windows forms.
We can also create extended advanced forms using only panels.(see above images,image 1 & 2)
Download the source code to view code for those forms.
See above image for better understanding of resizing our customized form and BlackForm.cs in file.
In this article we will create Blue colored resizable custom windows form, change colors of panels and buttons as you wish. You can use Custom Controls to design a form. Dont have Custom Controls?
Using following procedure you can also design Microsoft Office 2013 UI for any of your winform application such as Word, PowerPoint, Excel etc. Like following word screenshots.
Download the Download Office_Word_PP_Excel.zip file to view the UI code for Word, PowerPoint, Excel, DarkWord.
Start
Step 1
- Start Visual Studio and Create new Windows Forms Application project in C#. I have created CustomWindowsForm project.
- Download the source code and view the code for BlueForm.cs.
- Now set following Properties to created Form (Form1).
| ControlBox | false |
| BackColor | 30,60,150 |
| FormBorderStyle | None |
| Size | 684,461 |
To Add icon you can add again a panel/picturebox/toolstrip and set background image to it used as a window icon.
Step 2
- Now, Go to Project -> Add Class
- Enter Name
ButtonZ and click Add. - Now Copy and Paste following
ButtonZ code into your created class ButtonZ code. This button code is our Close & Minimize buttons of the form.
using System;
using System.Collections.Generic;

}
}
}
Step 3
- Now, Go to Project -> Add Class
- Enter Name
MinMaxButton and click Add. - Now Copy and Paste following
MinMaxButton code into your created class MinMaxButton code.
This code is for to create our maximize & restore down button when form is maximized.

switch (_customFormState)
{
case CustomFormState.Normal:
pe.Graphics.FillRectangle(new SolidBrush(color), ClientRectangle);
for (int i = 0; i < 2; i++)
{
pe.Graphics.DrawRectangle(new Pen(this.ForeColor), textX + i + 1, textY, 10, 10);
pe.Graphics.FillRectangle(new SolidBrush(this.ForeColor), textX + 1, textY - 1, 12, 4);
}
break;
case CustomFormState.Maximize:
pe.Graphics.FillRectangle(new SolidBrush(color), ClientRectangle);
for (int i = 0; i < 2; i++)
{
pe.Graphics.DrawRectangle(new Pen(this.ForeColor), textX + 5, textY, 8, 8);
pe.Graphics.FillRectangle(new SolidBrush(this.ForeColor), textX + 5, textY - 1, 9, 4);
pe.Graphics.DrawRectangle(new Pen(this.ForeColor), textX + 2, textY + 5, 8, 8);
pe.Graphics.FillRectangle(new SolidBrush(this.ForeColor), textX + 2, textY + 4, 9, 4);
}
break;
}
}
}
}
Step 4
Run your Form and exit it. For to create controls of above code for drag & drop components.
Step 5
- Drag & Drop Panel onto your Form (
TopBorderPanel) - Set following Properties to dropped panel.
| Name | TopBorderPanel |
| BackColor | 10,20,50 |
| Cursor | SizeNS |
| Dock | Top |
| Size | 684,2 |
Step 6
- Drag & Drop Panel onto your Form (
TopPanel) - Set following Properties to dropped panel.
| Name | TopPanel |
| BackColor | 20,40,80 |
| Cursor | Default |
| Dock | Top |
| Size | 680,35 |
Step 7
- Drag & Drop Panel onto your Form (
LeftPanel) - Set following Properties to dropped panel.
| Name | LeftPanel |
| BackColor | 10,20,50 |
| Cursor | SizeWE |
| Dock | Left |
| Size | 2,459 |
Step 8
- Drag & Drop Panel onto your Form (
RightPanel) - Set following Properties to dropped panel.
| Name | RightPanel |
| BackColor | 10,20,50 |
| Cursor | SizeWE |
| Dock | Right |
| Size | 2,459 |
Step 9
- Drag & Drop Panel onto your Form (
BottomPanel) - Set following Properties to dropped panel.
| Name | BottomPanel |
| BackColor | 10,20,50 |
| Cursor | SizeNS |
| Dock | Bottom |
| Size | 680,2 |
Step 10
- Drag & Drop ToolTip onto your form
Step 11
- Drag & Drop
ButtonZ onto TopPanel (_CloseButton) - Set following Properties to dropped button.
| Name | _CloseButton |
| Anchor | Top,Right |
| BZBackColor | 20,40,80 |
| DisplayText | X |
| Font | Microsoft YaHei UI, 11.25pt, style=Bold |
| ForeColor | White |
| Location | 639,3 |
| MouseClickColor1 | 150,0,0 |
| MouseHoverColor | 40,80,180 |
| Size | 35,25 |
| Text | X |
| TextLocation_X | 10 |
| TextLocation_Y | 4 |
| ToolTip on toolTip1 | Close |
Adjust button location as you wish.
Step 12
- Drag & Drop
ButtonZ onto TopPanel (_MinButton) - Set following Properties to dropped button.
| Name | _MinButton |
| Anchor | Top,Right |
| BZBackColor | 20,40,80 |
| DisplayText | _ |
| Font | Microsoft YaHei UI, 18pt, style=Bold |
| ForeColor | White |
| Location | 569,3 |
| MouseClickColor1 | 10,20,60 |
| MouseHoverColor | 40,80,180 |
| Size | 35,25 |
| Text | _ |
| TextLocation_X | 8 |
| TextLocation_Y | -14 |
| ToolTip on toolTip1 | Minimize |
Step 13
- Drag & Drop
MinMaxButton onto TopPanel (_MaxButton) - Set following Properties to dropped button.
| Name | _MaxButton |
| Anchor | Top,Right |
| BZBackColor | 20,40,80 |
| CFormState | Normal |
| ForeColor | White |
| Location | 604,3 |
| MouseClickColor1 | 10,20,60 |
| MouseHoverColor | 40,80,180 |
| Size | 35,25 |
| TextLocation_X | 11 |
| TextLocation_Y | 8 |
| ToolTip on toolTip1 | Maximize |
For text of our custom for, you can add Label and use it as a text of a form.
Step 14
Add following variables to code of Form1 globally:
bool isTopPanelDragged = false;
bool isLeftPanelDragged = false;
bool isRightPanelDragged = false;
bool isBottomPanelDragged = false;
bool isTopBorderPanelDragged = false;
bool isWindowMaximized = false;
Point offset;
Size _normalWindowSize;
Point _normalWindowLocation = Point.Empty;
isTopPanelDragged is to check that mouse down event triggered by top panel or not. Same for Left, Right, Bottom, TopBorder panels.isWindowMaximized is to check whether _MaxButton click event occured or not.- offset is temporary variable to store location of our form.
_normalWindowSize is to hold normal window size after clicking on _MaxButton for go to normal window size Same as for _normalWindowLocation only just to store form location.
Step 15
Now add Events to Panels and Buttons in Events Box. MouseDown, MouseMove & MouseUp events to Panels.
TopBorderPanel
TopBorderPanel_MouseDownTopBorderPanel_MouseMoveTopBorderPanel_MouseUp
TopPanel
TopPanel_MouseDownTopPanel_MouseMoveTopPanel_MouseUp
LeftPanel
LeftPanel_MouseDownLeftPanel_MouseMoveLeftPanel_MouseUp
RightPanel
RightPanel_MouseDownRightPanel_MouseMoveRightPanel_MouseUp
BottomPanel
BottomPanel_MouseDownBottomPanel_MouseMoveBottomPanel_MouseUp
_MinButton
_MaxButton
_CloseButton
Step 16
Once you added all above events to all components then replace your Form1.cs code with following code. Just make changes in classes, namespaces etc. Download the source code for view simple blue colored custom form.

Here is the output of above all procedures:
Well we have created a custom forms, so you directly cannot add some controls to a form like MenuStrip, SplitContainer etc. To add these controls first you need to add panels and add them onto that panel so that our customize form will not be changed.
