Question

i wanna ask how can i apply a nice shadow effect on my WindowsForm .net project ?!
i saw some codes on StackOverFlow But they only work on windows10 and they only two sides shadow , i want to have a FULL 4 sides shadow , (i mean shadow on 4 corners not only 2)

and thanks !

Answer 1

Create a new class that inherits from Form:

public class ShadowedForm : Form
{
// ...
}

Override the CreateParams property to add the WS_EX_COMPOSITED and CS_DROPSHADOW styles:

protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x02000000; // WS_EX_COMPOSITED
cp.ClassStyle |= 0x00020000; // CS_DROPSHADOW
return cp;
}
}

Override the OnPaint method to draw the shadow:

protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
using (var shadowBrush = new SolidBrush(Color.FromArgb(30, 0, 0, 0))) { var shadowSize = 10; var shadowRect = new Rectangle(-shadowSize, -shadowSize, Width + shadowSize, Height + shadowSize); e.Graphics.FillRectangle(shadowBrush, shadowRect); } }

Then use

Application.Run(new ShadowForm())
