此示例显示如何创建自定义组件并将其添加到报表设计器。自定义组件提供了在报表设计器中添加组件及其参数并在报表中使用的功能。例如，您可以添加 stimulsoft 报告中不存在的图表。

首先，指定属性及其值：

[StiServiceBitmap(typeof(MyCustomComponent), "CustomComponent.MyCustomComponent1.gif")]
[StiToolbox(true)]
[StiContextTool(typeof(IStiShift))]
[StiContextTool(typeof(IStiGrowToHeight))]
[StiDesigner(typeof(MyCustomComponentDesigner))]
[StiV1Builder(typeof(MyCustomComponentV1Builder))]
[StiV2Builder(typeof(MyCustomComponentV2Builder))]
[StiGdiPainter(typeof(MyCustomComponentGdiPainter))]

...

接下来，创建一个MyCustomComponent类并指定继承的类。此外，覆盖所需的组件属性：

...

public class MyCustomComponent : StiComponent, IStiBorder, IStiBrush
{
	#region StiComponent override
	/// <summary>
	/// Gets value to sort a position in the toolbox.
	/// </summary>
	public override int ToolboxPosition
	{
		get
		{
			return 500;
		}
	}
	
	/// <summary>
	/// Gets a localized name of the component category.
	/// </summary>
	public override string LocalizedCategory
	{
		get
		{
			return StiLocalization.Get("Report", "Components");
		}
	}
	
	/// <summary>
	/// Gets a localized component name.
	/// </summary>
	public override string LocalizedName
	{
		get
		{
			return "MyCustomComponent1";
		}
	}
	#endregion

...

向组件添加新属性 -Border和Brush，并设置它们的默认值。

...

	#region IStiBorder
	private StiBorder border = new StiBorder();
	/// <summary>
	/// Gets or sets a frame of the component.
	/// </summary>
	[StiCategory("Appearance")]
	[StiSerializable]
	[Description("Gets or sets frame of the component.")]
	public StiBorder Border
	{
		get
		{
			return border;
		}
		set
		{
			border = value;
		}
	}
	#endregion
	
	#region IStiBrush
	private StiBrush brush = new StiSolidBrush(Color.Transparent);
	/// <summary>
	/// Gets or sets a brush to fill a component.
	/// </summary>
	[StiCategory("Appearance")]
	[StiSerializable]
	[Description("Gets or sets a brush to fill a component.")]
	public StiBrush Brush
	{
		get
		{
			return brush;
		}
		set
		{
			brush = value;
		}
	}
	#endregion
	
...

向该MyCustomComponent类型的新组件添加必要的构造函数：

...

	#region this
	/// <summary>
	/// Creates a new component of the type MyCustomComponent.
	/// </summary>
	public MyCustomComponent() : this(RectangleD.Empty)
	{
	
	}
	
	/// <summary>
	/// Creates a new component of the type MyCustomComponent.
	/// </summary>
	/// <param name="rect">The rectangle describes size and position of the component.</param>
	public MyCustomComponent(RectangleD rect) : base(rect)
	{
		PlaceOnToolbox = true;
	}
	#endregion
}

该AddCustomComponent()方法将自定义组件添加到StiConfig.Services集合中，现在我们可以在报表设计器工具栏中找到它：

private static void AddCustomComponent()
{
	StiConfig.Load();
	
	StiOptions.Engine.ReferencedAssemblies = new string[] {
		"System.Dll",
		"System.Drawing.Dll",
		"System.Windows.Forms.Dll",
		"System.Data.Dll",
		"System.Xml.Dll",
		"Stimulsoft.Controls.Dll",
		"Stimulsoft.Base.Dll",
		"Stimulsoft.Report.Dll",
		
		#region Add reference to your assembly
		"CustomComponent.exe"
		#endregion
	};
	
	StiConfig.Services.Add(new MyCustomComponent());
	StiConfig.Services.Add(new MyCustomComponentWithDataSource());
	StiConfig.Services.Add(new MyCustomComponentWithExpression());
	StiConfig.Save();
}
