2 Jun 20212 minutes to read

The XPTaskBar’s Paint event can be handled to custom draw the background using the LinearGradientBrush as given below.

c#

private void xpTaskBar1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)

{

Rectangle rc = this.ClientRectangle;

int gradientWidth = rc.Width;

LinearGradientBrush lg = new System.Drawing.Drawing2D.LinearGradientBrush( new Point(0, 0), new Point(0, gradientWidth), Color.SandyBrown, Color.White);

 

// LinearGradientBrush lg = new System.Drawing.Drawing2D.LinearGradientBrush(rc, Color.SandyBrown, Color, LinearGradientMode.ForwardDiagonal);

float[] positions = {0.0f, 0.005f, 0.95f, 1.0f};

float[] factors = {0.4f, 1.0f, 0.05f, 0.4f};

 

// Blend Settings

Blend blend = new Blend();

blend.Factors = factors;

blend.Positions = positions;

lg.Blend = blend;

e.Graphics.FillRectangle(lg, 0, 0, gradientWidth, rc.Height);

lg.Dispose();

}

vb
