在SharePoint 2010中实现View Action Button效果。
http://www.sharepointblogs.be/blogs/vandest/archive/2008/06/20/view-action-button.aspx
1. 创建自定义字段类ViewActionButton 继承自 SPTextField
public class ViewActionButton : SPField
{
#region Constructors
public ViewActionButton(SPFieldCollection fields, string fieldName)
: base(fields, fieldName) { } public ViewActionButton(SPFieldCollection fields, string typeName, string displayName)
: base(fields, typeName, displayName) { }
#endregion #region Reimplementation of Get/Set Custom Property
public new void SetCustomProperty(string propertyName, object propertyValue)
{
Type type = typeof(SPField);
MethodInfo setField = type.GetMethod("SetFieldAttributeValue", BindingFlags.NonPublic | BindingFlags.Instance);
object o = setField.Invoke(this, new object[] { propertyName, propertyValue.ToString() });
} public new string GetCustomProperty(string propertyName)
{
Type type = typeof(SPField);
MethodInfo getField = type.GetMethod("GetFieldAttributeValue", BindingFlags.NonPublic | BindingFlags.Instance, null, new Type[] { typeof(String) }, null);
object o = getField.Invoke(this, new object[] { propertyName }); return o as String;
}
#endregion
}
2. 创建字段属性用户控件ActionButtonPropertyControl
ActionButtonPropertyControl.ascx
<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
<%@ Assembly Name="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Register Tagprefix="Utilities" Namespace="Microsoft.SharePoint.Utilities" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Register Tagprefix="asp" Namespace="System.Web.UI" Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" %>
<%@ Register TagPrefix="wssuc" TagName="InputFormControl" src="~/_controltemplates/InputFormControl.ascx" %>
<%@ Import Namespace="Microsoft.SharePoint" %>
<%@ Register Tagprefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ActionButtonPropertyControl.ascx.cs" Inherits="CustomFieldProject.ControlTemplates.ViewActionButton.ActionButtonPropertyControl" %>
<wssuc:InputFormControl runat="server" LabelText="Action URL:">
<Template_Control>
<span style="white-space: nowrap;">
<SharePoint:ProjectProperty runat="server" Property="Url" />/
<SharePoint:InputFormTextBox ID="iftxtUrl" runat="server" CssClass="ms-input" TextMode="SingleLine" Width="" />
<asp:RequiredFieldValidator ID="rfvUrl" runat="server" ControlToValidate="iftxtUrl" Display="Dynamic" ErrorMessage="*" />
</span>
</Template_Control>
</wssuc:InputFormControl> <wssuc:InputFormControl runat="server" LabelText="Format:">
<Template_Control>
<asp:DropDownList ID="ifrbFormat" runat="server">
<asp:ListItem Selected="True" Value="Button" Text="Button" />
<asp:ListItem Selected="False" Value="Hyperlink" Text="Hyperlink" />
</asp:DropDownList>
</Template_Control>
</wssuc:InputFormControl> <wssuc:InputFormControl runat="server" LabelText="CSS-Class:">
<Template_Control>
<SharePoint:InputFormTextBox ID="iftxtCssClass" runat="server" CssClass="ms-input" TextMode="SingleLine" Text="ms-ButtonHeightWidth" />
<asp:RequiredFieldValidator ID="rfvCssClass" runat="server" ControlToValidate="iftxtCssClass" Display="Dynamic" ErrorMessage="*" />
</Template_Control>
</wssuc:InputFormControl>
请根据实际情况修改下列内容:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ActionButtonPropertyControl.ascx.cs" Inherits="CustomFieldProject.ControlTemplates.ViewActionButton.ActionButtonPropertyControl" %>
ActionButtonPropertyControl.ascx.cs
public partial class ActionButtonPropertyControl : UserControl, IFieldEditor
{
#region Controls and Properties to get/set value of Controls
// protected InputFormTextBox iftxtUrl;
public string ActionURL
{
get { return iftxtUrl.Text; }
set { iftxtUrl.Text = value; }
} //protected DropDownList ifrbFormat;
public string Format
{
get { return ifrbFormat.SelectedValue; }
set { ifrbFormat.SelectedValue = value; }
} //protected InputFormTextBox iftxtCssClass;
public string CssClass
{
get { return iftxtCssClass.Text; }
set { iftxtCssClass.Text = value; }
}
#endregion #region IFieldEditor Members
public bool DisplayAsNewSection
{
get { return false; }
} public void InitializeWithField(SPField field)
{
// If it's no postback (first time loading on Edit Field)
if (!IsPostBack)
{
CustomFieldTypes.ViewActionButton myField = field as CustomFieldTypes.ViewActionButton;
if (null != myField)
{
// Set values in control based on values in myField
Type type = typeof(ActionButtonPropertyControl); foreach (PropertyInfo prop in type.GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly))
{
if (prop.CanWrite)
prop.SetValue(this, myField.GetCustomProperty(prop.Name), null);
}
}
}
} public void OnSaveChange(SPField field, bool isNewField)
{
CustomFieldTypes.ViewActionButton myField = field as CustomFieldTypes.ViewActionButton; if (null != myField)
{
// Set values in myField based on values in control
Type type = typeof(ActionButtonPropertyControl); foreach (PropertyInfo prop in type.GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly))
{
if (prop.CanWrite)
myField.SetCustomProperty(prop.Name, prop.GetValue(this, null));
}
}
}
#endregion
}
3. 创建自定义字段定义文件fldtypes_ViewActionButton
<?xml version="1.0" encoding="utf-8" ?> <FieldTypes>
<FieldType>
<Field Name="TypeName">ViewActionButton</Field>
<Field Name="TypeDisplayName">View Action Button</Field>
<Field Name="TypeShortDescription">View Action Button</Field>
<Field Name="ParentType">Text</Field>
<Field Name="UserCreatable">TRUE</Field>
<Field Name="ShowOnListCreate">TRUE</Field>
<Field Name="ShowOnSurveyCreate">TRUE</Field>
<Field Name="ShowOnDocumentLibraryCreate">TRUE</Field>
<Field Name="ShowOnColumnTemplateCreate">TRUE</Field>
<Field Name="Sortable">FALSE</Field>
<Field Name="Filterable">FALSE</Field>
<Field Name="CAMLRendering">TRUE</Field>
<Field Name="FieldEditorUserControl">/_controltemplates/ViewActionButton/ActionButtonPropertyControl.ascx</Field>
<Field Name="FieldTypeClass">CustomFieldProject.CustomFieldTypes.ViewActionButton, $SharePoint.Project.AssemblyFullName$</Field> <RenderPattern Name="DisplayPattern">
<SetVar Name="ActionURLWithParams">
<HttpVDir CurrentWeb="TRUE" />
<HTML>/</HTML>
<Property Select="ActionURL"/>
<HTML>
<![CDATA[?ID=]]>
</HTML>
<Column Name="ID" />
<HTML>
<![CDATA[&List=]]>
</HTML>
<ListProperty Select="Name" />
</SetVar> <Switch>
<Expr>
<Property Select="Format"/>
</Expr>
<Case Value="Button">
<HTML>
<![CDATA[<input type="button" class="]]>
</HTML>
<Property Select="CssClass"/>
<HTML>
<![CDATA[" value="]]>
</HTML>
<Property Select="DisplayName"/>
<HTML>
<![CDATA[" onclick="javascript:window.location=STSPageUrlValidation(']]>
</HTML>
<GetVar Name="ActionURLWithParams" />
<HTML>
<![CDATA[&Source=' + GetSource()); return false;" />]]>
</HTML>
</Case>
<Case Value="Hyperlink">
<HTML>
<![CDATA[<a class="]]>
</HTML>
<Property Select="CssClass"/>
<HTML>
<![CDATA[" href="]]>
</HTML>
<GetVar Name="ActionURLWithParams" />
<HTML>
<![CDATA[" onclick="javascript:this.href = unescapeProperly(escape(this.href)); GoToLink(this); return false;">]]>
</HTML>
<Property Select="DisplayName"/>
<HTML>
<![CDATA[<a />]]>
</HTML>
</Case>
<Default>
<HTML><![CDATA[<span style="font-style: italic;">Invalid format</span>]]></HTML>
</Default>
</Switch>
</RenderPattern>
<RenderPattern Name="EditPattern"></RenderPattern>
<RenderPattern Name="NewPattern" DisplayName="NewPattern"></RenderPattern>
<RenderPattern Name="PreviewDisplayPattern">
<HTML><![CDATA[<span style="font-style: italic;">View Action Button</span>]]></HTML>
</RenderPattern>
<RenderPattern Name="PreviewEditPattern"></RenderPattern>
<RenderPattern Name="PreviewNewPattern"></RenderPattern>
</FieldType>
</FieldTypes>
由于在SharePoint 2010中已经不推荐使用RenderPattern方式来呈现字段,需要将“CAMLRendering”设置成True,否则需要通过自定义XSLT来实现。
<Field Name="CAMLRendering">TRUE</Field>
请根据实际情况修改下列内容:
<Field Name="FieldTypeClass">CustomFieldProject.CustomFieldTypes.ViewActionButton, $SharePoint.Project.AssemblyFullName$</Field>
4. 创建自定义XSLT样式文件
如果已经CAMLRendering设置成True,则不必自定义XSLT样式。
目前仍然没有找到方法能够在XSLT中读取字段的自定义属性。
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:x="http://www.w3.org/2001/XMLSchema"
xmlns:d="http://schemas.microsoft.com/sharepoint/dsp"
version="1.0"

xmlns:asp="http://schemas.microsoft.com/ASPNET/20"
xmlns:__designer="http://schemas.microsoft.com/WebParts/v2/DataView/designer"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:SharePoint="Microsoft.SharePoint.WebControls"
xmlns:ddwrt2="urn:frontpage:internal"> <xsl:template match ="FieldRef[@FieldType='ViewActionButton']" mode="Text_body">
<xsl:param name="thisNode" select="."/>
<xsl:variable name="ActionURL" select="current()/@ActionURL" />
<xsl:variable name="Format" select="current()/@Format" />
<xsl:variable name="CssClass" select="current()/@CssClass" /> <xsl:choose>
<xsl:when test="$Format='Button'">
<input type="button">
<xsl:attribute name="class">
<xsl:value-of select="$CssClass"/>
</xsl:attribute>
<xsl:attribute name="value">
<xsl:value-of select="$thisNode/@Name"/>
</xsl:attribute>
<xsl:attribute name="onclick">
javascript:window.location=STSPageUrlValidation('$ActionURL?ID=$thisNode/@ID&List=$List');
</xsl:attribute>
</input>
</xsl:when>
<xsl:otherwise>
<a target="_blank">
<xsl:attribute name="class">
<xsl:value-of select="$CssClass"/>
</xsl:attribute>
<xsl:attribute name="href">
<xsl:value-of select="$ActionURL" />?ID=<xsl:value-of select="$thisNode/@ID" />&List=<xsl:value-of select="$List" />
</xsl:attribute>
<xsl:value-of select="current()/@DisplayName"/>
</a>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
