How to draw gradient tabs?

Platform: WinForms |
Control: TabControlAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014

 

You can handle the DrawItem Event of TabControlAdv and then set the gradient by using the LinearGradientBrush

Here is the code snippet:

C#

private void tabControlAdv1_DrawItem(object sender, Syncfusion.Windows.Forms.Tools.DrawTabEventArgs drawItemInfo)

{

// Use LinearGradientBrush to set gradient.

// Use GetTabRect to get the rectangle of the tabs.

if(drawItemInfo.Index != this.tabControlAdv1.SelectedIndex)

{

// For the non-selected tabs

lgb = new System.Drawing.Drawing2D.LinearGradientBrush(

this.tabControlAdv1.GetTabRect(drawItemInfo.Index), Color.FromArgb(197,197,173), Color.FromArgb(228,228,212), LinearGradientMode.Horizontal);

}

else

{

// For the selected tab

lgb = new System.Drawing.Drawing2D.LinearGradientBrush(

this.tabControlAdv1.GetTabRect(drawItemInfo.Index), Color.White, Color.WhiteSmoke, LinearGradientMode.Horizontal);

}

float[] positions = {0.0f, 0.05f, 0.95f, 1.0f};

float[] factors = {0.4f, 1.0f, 0.05f, 0.04f};

// Blend settings

Blend blend = new Blend();

blend.Factors = factors;

blend.Positions = positions;

lgb.Blend = blend;

drawItemInfo.Graphics.FillRectangle(lgb,this.tabControlAdv1.GetTabRect(drawItemInfo.Index));

lgb.Dispose();

// Draw the default borders and interior (text and image)

drawItemInfo.DrawBorders();

drawItemInfo.DrawInterior();

}
