1. 首先创建一个Field 项目CustomFields.
2. 添加三个类文件：FieldAddressValue.cs ，FieldAddress.cs，AddressFieldControl.cs三个文件．
１） FieldAddressValue.cs源代码如下：
using System;using System.Collections.Generic;using System.Text;using Microsoft.SharePoint;using System.Web;namespace CustomFields
{
class FieldAddressValue : SPFieldMultiColumnValue
{
private const int numberOfFields = 4; public FieldAddressValue() : base(numberOfFields) { } public FieldAddressValue(string value) : base(value) { } public string Address { get { return this[0]; } set { this[0] = value; }
} public string Zip { get { return this[1]; } set { this[1] = value; } } public string City { get { return this[2]; } set { this[2] = value; } } public string Country { get { return this[3]; } set { this[3] = value; } } }
}２） FieldAddress.cs源代码如下：
using System;using System.Collections.Generic;using System.Text;using System.Web;using Microsoft.SharePoint;using Microsoft.SharePoint.WebControls;using CustomFields.WebControls;namespace CustomFields{ class FieldAddress : SPFieldMultiColumn { public FieldAddress(SPFieldCollection fields, string fieldName) : base(fields, fieldName) { } public FieldAddress(SPFieldCollection fields, string typeName, string displayName) : base(fields, typeName, displayName) { } public override BaseFieldControl FieldRenderingControl { get { BaseFieldControl fldControl = new AddressFieldControl(); fldControl.FieldName = InternalName; return fldControl; } } public override object GetFieldValue(string value) { if(string .IsNullOrEmpty(value)) return null; return new FieldAddressValue(value); } }}３) AddressFieldControl.cs源代码如下：
using System;using System.Collections.Generic;using System.Text;using Microsoft.SharePoint;using Microsoft.SharePoint.WebControls;using System.Web;using System.Web.UI.WebControls;namespace CustomFields.WebControls{ class AddressFieldControl : BaseFieldControl { protected TextBox addressBox; protected TextBox zipBox; protected TextBox cityBox; protected TextBox countryBox; protected override string DefaultTemplateName { get { return "AddressFieldRendering"; } } public override object Value { get { EnsureChildControls(); FieldAddressValue fieldValue = new FieldAddressValue(); fieldValue.Address = addressBox.Text.Trim(); fieldValue.Zip = zipBox.Text.Trim(); fieldValue.City = cityBox.Text.Trim(); fieldValue.Country = countryBox.Text.Trim(); return fieldValue; } set { EnsureChildControls(); FieldAddressValue fieldValue = (FieldAddressValue)value; addressBox.Text = fieldValue.Address; zipBox.Text = fieldValue.Zip; cityBox.Text = fieldValue.City; countryBox.Text = fieldValue.Country; } } public override void Focus() { EnsureChildControls(); addressBox.Focus(); } protected override void CreateChildControls() { if (Field == null) return; base.CreateChildControls(); if (ControlMode == SPControlMode.Display) return; addressBox = (TextBox)TemplateContainer.FindControl("addressBox"); if (addressBox == null) throw new ArgumentException("Corrupted AddressFieldRendering template - missing addressBox. "); addressBox.TabIndex = TabIndex; addressBox.CssClass = CssClass; addressBox.ToolTip = Field.Title + " Address"; zipBox = (TextBox)TemplateContainer.FindControl("zipBox"); if (zipBox == null) throw new ArgumentException("corrupted AddressFieldRendering template - missing zipBox."); zipBox.TabIndex = TabIndex; zipBox.CssClass = CssClass; zipBox.ToolTip = Field.Title + " Zipcode"; cityBox = (TextBox)TemplateContainer.FindControl("cityBox"); if (cityBox == null) throw new ArgumentException("corrupted AddressFieldRendering template - missing cityBox."); cityBox.TabIndex = TabIndex; cityBox.CssClass = CssClass; cityBox.ToolTip = Field.Title + " City"; countryBox = (TextBox)TemplateContainer.FindControl("countryBox"); if (countryBox == null) throw new ArgumentException("corrupted AddressFieldRendering template - missing countryBox."); countryBox.TabIndex = TabIndex; countryBox.CssClass = CssClass; countryBox.ToolTip = Field.Title + " Country"; if (ControlMode == SPControlMode.New) { addressBox.Text = Field.GetCustomProperty("DefaultStreet").ToString(); zipBox.Text = Field.GetCustomProperty("DefaultZip").ToString(); cityBox.Text = Field.GetCustomProperty("DefaultCity").ToString(); countryBox.Text = Field.GetCustomProperty("DefaultCountry").ToString(); } } }}３. 强名称编译程序集．
４. 添加一个类型定义文件fldtypes_custom.xml．
fldtypes_custom.xml文件内容如下：
<?xml version="1.0" encoding="utf-8"?><FieldTypes> <FieldType> <Field Name="TypeName">Address</Field> <Field Name="ParentType">MultiColumn</Field> <Field Name="TypeDisplayName">Address</Field> <Field Name="TypeShortDescription">Address (street + nr, zip, city and country)</Field> <Field Name="UserCreatable">TRUE</Field> <Field Name="ShowOnListCreate">TRUE</Field> <Field Name="ShowOnDocumentLibraryCreate">TRUE</Field> <Field Name="ShowOnSurveyCreate">TRUE</Field> <Field Name="ShowOnColumnTemplateCreate">TRUE</Field> <Field Name="FieldTypeClass">CustomFields.FieldAddress,CustomFields, Version=1.0.0.0, Culture=neutral, PublicKeyToken=55a361e8b234515f</Field> <PropertySchema> <Fields> <Field Name="DefaultStreet" DisplayName="Default Street:" MaxLength="50" DisplaySize="30" Type="Text"> <Default>XiaoYuan Road</Default> </Field> <Field Name="DefaultZip" DisplayName="Default Zip:" MaxLength="10" DisplaySize="10" Type="Text"> <Default>100027</Default> </Field> <Field Name="DefaultCity" DisplayName="Default City:" MaxLength="50" DisplaySize="30" Type="Text"> <Default>Beijing</Default> </Field> <Field Name="DefaultCountry" DisplayName="Default Country:" MaxLength="50" DisplaySize="30" Type="Text"> <Default>China</Default> </Field> </Fields> </PropertySchema> <RenderPattern Name="DisplayPattern"> <Switch> <Expr><Column/></Expr> <Case Value=""> </Case> <Default> <Column SubColumnNumber="0" HTMLEncode="TRUE" /> <HTML><![CDATA[<BR>]]></HTML> <Column SubColumnNumber="1" HTMLEncode="TRUE"/> <HTML><![CDATA[ ---- ]]></HTML> <Column SubColumnNumber="2" HTMLEncode="TRUE"/> <HTML><![CDATA[<BR>]]></HTML> <Column SubColumnNumber="3" HTMLEncode="TRUE"/> </Default> </Switch> </RenderPattern> </FieldType></FieldTypes>５. 添加一个模板文件AddressFieldRendering.ascx．
AddressFieldRendering.ascx文件内容如下：
<%@ Control Language="C#" Debug="true"%><%@ Assembly Name="Microsoft.SharePoint,Version=12.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c" %><%@ Register TagPrefix="SharePoint" Assembly="Microsoft.SharePoint,Version=12.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c" namespace="Microsoft.SharePoint.WebControls"%><SharePoint:RenderingTemplate ID="AddressFieldRendering" runat="server"> <Template> <table class="ms-form"> <tr> <td>Address:</td> <td><asp:TextBox ID="addressBox" MaxLength="255" size="50" runat="server" /></td> </tr> <tr> <td>Zip:</td> <td><asp:TextBox ID="zipBox" MaxLength="10" size="5" runat="server" /></td> </tr> <tr> <td>City:</td> <td><asp:TextBox ID="cityBox" MaxLength="50" size="15" runat="server" /></td> </tr> <tr> <td>Country:</td> <td><asp:TextBox ID="countryBox" MaxLength="50" size="15" runat="server" /></td> </tr> </table> </Template></SharePoint:RenderingTemplate>６. 部署．
1) 把 程序集CustomFields加入GAC.
2) 把类型定义文件fldtypes_custom.xml拷贝到目录c:\program...\12\TEMPLATE\XML下．
3) 把模板文件AddressFieldRendering.ascx拷贝到目录c:\program...\12\TEMPLATE\CONTROLTEMPLATES下．
4) 重起IIS.
