Use the EndColor property to specify the color to fill the end part of the bar, if the EndShape property is not exShapeIconEmpty. Use the Color property to specify the color to fill the middle part of the bar. Use the StartColor and StartShape properties to define the look and feel for the starting part of the bar. Use the AddShapeCorner property to add custom icons to the bars. In this case, the icon is processed before displaying based on the StartColor/ EndColor property. For instance, if you add an black and white icon, and the StartColor/EndColor is red, the icon will be painted in red. Instead, if the StartColor/EndColor property is -1 ( 0xFFFFFFFF, not white which is 0x00FFFFFF ), the icon is painted as it was

In VB.NET or C# you require the following functions until the .NET framework will provide:

You can use the following VB.NET function:

     Shared Function ToUInt32(ByVal c As Color) As UInt32
         Dim i As Long
	 i = c.R
	 i = i + 256 * c.G
	 i = i + 256 * 256 * c.B
	 ToUInt32 = Convert.ToUInt32(i)
     End Function 

You can use the following C# function:

private UInt32 ToUInt32(Color c)
{
	long i;
	i = c.R;
	i = i + 256 * c.G;
	i = i + 256 * 256 * c.B;
	return Convert.ToUInt32(i);
}

The following VB sample defines a new bar that looks like this :

With G2antt1.Chart.Bars.Add("Task2")
    .Pattern = exPatternShadow
    .Color = RGB(0, 0, 255)
    .EndShape = exShapeIconCircleDot
    .EndColor = RGB(255, 0, 0)
End With

The following C++ sample defines a bar that looks like this above:

CBar bar = m_g2antt.GetChart().GetBars().Add("Task2");
bar.SetPattern( 3 /*exPatternShadow*/ );
bar.SetColor( RGB(0, 0, 255) );
bar.SetEndShape( 4 /* exShapeIconCircleDot*/ );
bar.SetEndColor( RGB(255, 0, 0) );

The following VB.NET sample defines a bar that looks like this above:

With AxG2antt1.Chart.Bars.Add("Task2")
    .Pattern = EXG2ANTTLib.PatternEnum.exPatternShadow
    .Color = RGB(0, 0, 255)
    .EndShape = EXG2ANTTLib.ShapeCornerEnum.exShapeIconCircleDot
    .EndColor = RGB(255, 0, 0)
End With

The following VB.NET sample adds a custom icon to the start of all Task bars:

With AxG2antt1.Chart.Bars
    .AddShapeCorner(12345, 1)
    .Item("Task").StartShape = 12345
    .Item("Task").StartColor = UInteger.MaxValue
End With

The following C# sample defines a bar that looks like this above:

EXG2ANTTLib.Bar bar = axG2antt1.Chart.Bars.Add("Task2");
bar.Pattern = EXG2ANTTLib.PatternEnum.exPatternShadow;
bar.Color = ToUInt32(Color.FromArgb(0, 0, 255));
bar.EndShape = EXG2ANTTLib.ShapeCornerEnum.exShapeIconCircleDot;
bar.EndColor = ToUInt32(Color.FromArgb(255, 0, 0));

The following C# sample adds a custom icon to the start of all Task bars:

EXG2ANTTLib.Bars bars = axG2antt1.Chart.Bars;
bars.AddShapeCorner(12345, 1);
bars["Task"].StartShape = EXG2ANTTLib.ShapeCornerEnum.exShapeIconEmpty + 12345;
bars["Task"].StartColor = 0xFFFFFFFF;

The following VFP sample defines a bar that looks like this above:

with thisform.G2antt1.Chart.Bars.Add("Task2")
	.Pattern = 3 && exPatternShadow
	.Color = RGB(0, 0, 255)
	.EndShape = 4 && exShapeIconCircleDot
	.EndColor = RGB(255, 0, 0)
EndWith
