强大的SPGridView

先看看SPGridView能实现的效果:
1)分组,分页

2)下拉菜单

3)过滤

以上效果是不是跟系统的列表一模一样?

SPGridView继承于GrieView,拥有GridView的所有功能,并扩展了以上功能。

下面讲述SPGridView的两种用法:采用自定义数据源和采用WSS的列表作为数据源。

利用SPGridView显示自定义数据源

Step1:
新建一个页面,写入如下内容: 

<% @ Page MasterPageFile="~/_layouts/application.master"   Language="C#" AutoEventWireup="true"  CodeFile="SPGridViewTest.aspx.cs" Inherits="_Default"  %>
<% @ Register Assembly="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"
    Namespace
="Microsoft.SharePoint.WebControls" TagPrefix="cc1" 
%>
< asp:Content  ID ="Content1"  ContentPlaceHolderID ="PlaceHolderMain"  runat ="server" >
        
< cc1:SPGridView  ID ="SPGridView1"  runat ="server"  AutoGenerateColumns ="False"  AllowPaging ="True"  PageSize ="3"   >
            
< AlternatingRowStyle  CssClass ="ms-alternating"   />
            
< SelectedRowStyle  CssClass ="ms-selectednav"  Font-Bold ="True"   />
        
</ cc1:SPGridView >
        
< div  style ="text-align:center" >
    
< cc1:SPGridViewPager  ID ="SPGridViewPager1"  runat ="server"  GridViewId ="SPGridView1" >     
    
</ cc1:SPGridViewPager ></ div >
 
</ asp:Content >

注意:
SPGridView不支持自动生成列,所以 一定要设置AutoGenerateColums为false。
SPGridView直接启用了分页,并且,页面放入一个SPGrieViewPager,来实现分页。
Step2:
在CodeFile里写一个提供测试数据的函数:

using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;

public  DataTable GetDataTable()
    
{
        DataTable tblData 
= new DataTable();
        tblData.Columns.Add(
"Title");
        tblData.Columns.Add(
"Author");
        tblData.Columns.Add(
"Rating");

        tblData.Rows.Add(
"Obsession""Robards, Karen"2);
        tblData.Rows.Add(
"Vanished""Robards, Karen"3);
        tblData.Rows.Add(
"Magician: Apprentice""Feist, Raymong E."4);
        tblData.Rows.Add(
"Magician: Master""Feist, Raymong E."5);
        tblData.Rows.Add(
"Silverthorn""Feist, Raymong E."4);
        tblData.Rows.Add(
"Lord Foul's Bane""Donaldson, Stephen R."3);
        tblData.Rows.Add(
"The Illearth War""Donaldson, Stephen R."4);

        
return tblData;
    }
 

Step3:
在Page_Load里写代码,加入ObjectDataSource控件,用这个控件来调用上面的GetDateTable函数。

  ObjectDataSource odsDataSource  =   new  ObjectDataSource();
        odsDataSource.ID 
=   " ExampleSource " ;
        odsDataSource.TypeName 
=   this .GetType().FullName  +   " , "   +   this .GetType().Assembly.FullName;
        odsDataSource.SelectMethod 
=   " GetDataTable " ;
        Controls.Add(odsDataSource);

有人可能要奇怪了,为什么要用ObjectDataSource来调用GetDataTable,直接给SPGridView的DataSource属性赋值不行吗?
答案是:可以的。但是,那样的话,你就不的不再写一些代码来处理SPGridView的过滤和排序事件 。而ObjectDataSource是可以自动来处理这些事件的。
Step4:继续在Page_Load写代码,设置SPGridView的过滤格式和过滤属性,如果不这样设置的话,过滤功能不会起效(这个设置可是我起早摸黑,用reflector看它的代码才发现的...)。

    // {0}表示过滤值,{1}表示过滤字段值
        SPGridView1.FilteredDataSourcePropertyFormat  =   " {1}='{0}' " ;
        SPGridView1.FilteredDataSourcePropertyName 
=   " FilterExpression "  ;    
        SPGridView1.EnableViewState 
=   false ;

Step4:继续在Page_Load写代码,添加字段,并启用排序 :

// 添加字段
        SPBoundField col  =   new  SPBoundField();
        col.DataField 
=   " Title " ;
        col.SortExpression 
=   " Title " ;
        col.HeaderText 
=   " Title " ;
        SPGridView1.Columns.Add(col);

        col 
=   new  SPBoundField();
        col.DataField 
=   " Author " ;
        col.SortExpression 
=   " Author " ;
        col.HeaderText 
=   " Author " ;
        SPGridView1.Columns.Add(col);

        col 
=   new  SPBoundField();
        col.DataField 
=   " Rating " ;
        col.SortExpression 
=   " Rating " ;
        col.HeaderText 
=   " Rating " ;
        SPGridView1.Columns.Add(col);
        SPGridView1.AllowSorting 
=   true ;

Step5:设置过滤字段:

SPGridView1.AllowFiltering  =   true ;

SPGridView1.FilterDataFields 
=   " ,Author,Rating " ;

注意 :开始的列如果不启用过滤需要加 “,”。

Step6:继续在Page_Load写代码,设置分组:

// 设置分组
        SPGridView1.AllowGrouping  =   true ;
        SPGridView1.AllowGroupCollapse 
=   true ;
        SPGridView1.GroupField 
=   " Title " ;
        SPGridView1.GroupDescriptionField 
=   " Title " ;
        SPGridView1.GroupFieldDisplayName 
=   " 分组: " ;

Step7:Continue...,添加一个有下拉菜单的字段:

   // 添加下拉菜单字段
        SPMenuField colMenu  =   new  SPMenuField();
        colMenu.HeaderText 
=   " Presenter Name " ;
        colMenu.TextFields 
=   " Title " ;

        
// 指定关联的菜单ID
        colMenu.MenuTemplateId  =   " PresenterListMenu " ;
        colMenu.NavigateUrlFields 
=   " Title,Rating " ;
        colMenu.NavigateUrlFormat 
=   " do.aspx?p={0}&q={1} " ;
        colMenu.TokenNameAndValueFields 
=   " EDIT=Title,NAME=Rating " ;
        colMenu.SortExpression 
=   " Title " ;

        
// 菜单
        MenuTemplate presenterListMenu  =   new  MenuTemplate();
        presenterListMenu.ID 
=   " PresenterListMenu " ;

        
// 菜单项
        MenuItemTemplate biogMenu  =   new  MenuItemTemplate(
            
" Read Biography " " /_layouts/images/EawfNewUser.gif " );
        biogMenu.ClientOnClickNavigateUrl 
=   " do.aspx?this=%EDIT%&that=%NAME% " ;
        
// entry.ClientOnClickScript = "your javascript here";
        presenterListMenu.Controls.Add(biogMenu);

        
// 菜单项
        MenuItemTemplate broadcastMenu  =   new  MenuItemTemplate(
                
" Recent Broadcasts " " /_layouts/images/ICWM.gif " );
        presenterListMenu.Controls.Add(broadcastMenu);

        
// 分割线
        MenuSeparatorTemplate sepMenu  =   new  MenuSeparatorTemplate();
        presenterListMenu.Controls.Add(sepMenu);

        
// 菜单项
        MenuItemTemplate favMenu  =   new  MenuItemTemplate(
               
" Add to Favorites " " /_layouts/images/addtofavorites.gif " );
        presenterListMenu.Controls.Add(favMenu);

        
this .Controls.Add(presenterListMenu);
        SPGridView1.Columns.Add(colMenu);

Step8:绑定数据源:

    // 绑定数据源
         this .SPGridView1.DataSourceID  =   " ExampleSource " ;
        
this .SPGridView1.DataBind();             

OK,可以看效果了~
注意:SPGridView一定要在WSS的环境中使用,所以各位做测试的时候需要把页面放到layouts中。
整个Page_Load的代码如下:


    protected void Page_Load(object sender, EventArgs e)
    
{
        ObjectDataSource odsDataSource 
= new ObjectDataSource();
        odsDataSource.ID 
= "ExampleSource";
        odsDataSource.TypeName 
= this.GetType().FullName + "," + this.GetType().Assembly.FullName;
        odsDataSource.SelectMethod 
= "GetDataTable";
        Controls.Add(odsDataSource);

        
//{0}表示过滤值,{1}表示过滤字段值
        SPGridView1.FilteredDataSourcePropertyFormat = "{1}='{0}'";
        SPGridView1.FilteredDataSourcePropertyName 
= "FilterExpression" ;    

        SPGridView1.EnableViewState 
= false;

        
//添加字段
        SPBoundField col = new SPBoundField();
        col.DataField 
= "Title";
        col.SortExpression 
= "Title";
        col.HeaderText 
= "Title";
        SPGridView1.Columns.Add(col);

        col 
= new SPBoundField();
        col.DataField 
= "Author";
        col.SortExpression 
= "Author";
        col.HeaderText 
= "Author";
        SPGridView1.Columns.Add(col);

        col 
= new SPBoundField();
        col.DataField 
= "Rating";
        col.SortExpression 
= "Rating";
        col.HeaderText 
= "Rating";
        SPGridView1.Columns.Add(col);
        SPGridView1.AllowSorting 
= true;

        SPGridView1.AllowFiltering 
= true;

        SPGridView1.FilterDataFields 
= ",Author,Rating";

        
//设置分组
        SPGridView1.AllowGrouping = true;
        SPGridView1.AllowGroupCollapse 
= true;
        SPGridView1.GroupField 
= "Title";
        SPGridView1.GroupDescriptionField 
= "Title";
        SPGridView1.GroupFieldDisplayName 
= "分组:";

        
//添加下拉菜单字段
        SPMenuField colMenu = new SPMenuField();
        colMenu.HeaderText 
= "Presenter Name";
        colMenu.TextFields 
= "Title";

        
//指定关联的菜单ID
        colMenu.MenuTemplateId = "PresenterListMenu";
        colMenu.NavigateUrlFields 
= "Title,Rating";
        colMenu.NavigateUrlFormat 
= "do.aspx?p={0}&q={1}";
        colMenu.TokenNameAndValueFields 
= "EDIT=Title,NAME=Rating";
        colMenu.SortExpression 
= "Title";

        
//菜单
        MenuTemplate presenterListMenu = new MenuTemplate();
        presenterListMenu.ID 
= "PresenterListMenu";

        
//菜单项
        MenuItemTemplate biogMenu = new MenuItemTemplate(
            
"Read Biography""/_layouts/images/EawfNewUser.gif");
        biogMenu.ClientOnClickNavigateUrl 
= "do.aspx?this=%EDIT%&that=%NAME%";
        
//entry.ClientOnClickScript = "your javascript here";
        presenterListMenu.Controls.Add(biogMenu);

        
//菜单项
        MenuItemTemplate broadcastMenu = new MenuItemTemplate(
                
"Recent Broadcasts""/_layouts/images/ICWM.gif");
        presenterListMenu.Controls.Add(broadcastMenu);

        
//分割线
        MenuSeparatorTemplate sepMenu = new MenuSeparatorTemplate();
        presenterListMenu.Controls.Add(sepMenu);

        
//菜单项
        MenuItemTemplate favMenu = new MenuItemTemplate(
               
"Add to Favorites""/_layouts/images/addtofavorites.gif");
        presenterListMenu.Controls.Add(favMenu);

        
this.Controls.Add(presenterListMenu);
        SPGridView1.Columns.Add(colMenu);

        
//绑定数据源
        this.SPGridView1.DataSourceID = "ExampleSource";
        
this.SPGridView1.DataBind();             
    }

 

利用SPGridView显示列表的数据

只要把数据源控件换成SPDataSource,然后利用SPDataSource连接相应的列表即可:

        SPDataSource odsDataSource  =   new  SPDataSource();
        odsDataSource.ID 
=   " ExampleSource " ;
        Controls.Add(odsDataSource);
        SPSite site 
=   new  SPSite( " http://ssjin073:9032 " );
        SPList list 
=  site.RootWeb.GetListFromUrl( " http://ssjin073:9032/Lists/List/AllItems.aspx " );
        odsDataSource.List 
=  list;


整个Page_Load代码如下:

  protected   void  Page_Load( object  sender, EventArgs e)
    
{
        SPDataSource odsDataSource 
= new SPDataSource();
        odsDataSource.ID 
= "ExampleSource";
        Controls.Add(odsDataSource);
        SPSite site 
= new SPSite("http://ssjin073:9032");
        SPList list 
= site.RootWeb.GetListFromUrl("http://ssjin073:9032/Lists/List/AllItems.aspx");
        odsDataSource.List 
= list;
        Response.Write(SPGridView1.FilterFieldName);

        SPGridView1.FilteredDataSourcePropertyFormat 
= "{1}='{0}'";
        SPGridView1.FilteredDataSourcePropertyName 
= "FilterExpression" ;    

        
this.SPGridView1.AutoGenerateColumns = false;
        SPGridView1.EnableViewState 
= false;

        
//添加字段
        SPBoundField col = new SPBoundField();
        col.DataField 
= "标题";
        col.SortExpression 
= "标题";
        col.HeaderText 
= "标题";
        SPGridView1.Columns.Add(col);

        col 
= new SPBoundField();
        col.DataField 
= "Origin";
        col.SortExpression 
= "Origin";
        col.HeaderText 
= "Origin";
        SPGridView1.Columns.Add(col);

        SPGridView1.AllowSorting 
= true;

        SPGridView1.AllowFiltering 
= true;

        SPGridView1.FilterDataFields 
= ",标题";

        
//设置分组
        SPGridView1.AllowGrouping = true;
        SPGridView1.AllowGroupCollapse 
= true;
        SPGridView1.GroupField 
= "Origin";
        SPGridView1.GroupDescriptionField 
= "Origin";
        SPGridView1.GroupFieldDisplayName 
= "分组:";

        
        
//添加下拉菜单字段
        SPMenuField colMenu = new SPMenuField();
        colMenu.HeaderText 
= "Presenter Name";
        colMenu.TextFields 
= "标题";

        
//指定关联的菜单ID
        colMenu.MenuTemplateId = "PresenterListMenu";
        
//colMenu.NavigateUrlFields = "标题";
       
// colMenu.NavigateUrlFormat = "do.aspx?p={0}&q={1}";
        
//colMenu.TokenNameAndValueFields = "EDIT=Title,NAME=Rating";
        
//colMenu.SortExpression = "Title";

        
//菜单
        MenuTemplate presenterListMenu = new MenuTemplate();
        presenterListMenu.ID 
= "PresenterListMenu";

        
//菜单项
        MenuItemTemplate biogMenu = new MenuItemTemplate(
            
"Read Biography""/_layouts/images/EawfNewUser.gif");
        biogMenu.ClientOnClickNavigateUrl 
= "do.aspx?this=%EDIT%&that=%NAME%";
        
//entry.ClientOnClickScript = "your javascript here";
        presenterListMenu.Controls.Add(biogMenu);

        
//菜单项
        MenuItemTemplate broadcastMenu = new MenuItemTemplate(
                
"Recent Broadcasts""/_layouts/images/ICWM.gif");
        presenterListMenu.Controls.Add(broadcastMenu);

        
//分割线
        MenuSeparatorTemplate sepMenu = new MenuSeparatorTemplate();
        presenterListMenu.Controls.Add(sepMenu);

        
//菜单项
        MenuItemTemplate favMenu = new MenuItemTemplate(
               
"Add to Favorites""/_layouts/images/addtofavorites.gif");
        presenterListMenu.Controls.Add(favMenu);

        
this.Controls.Add(presenterListMenu);
        SPGridView1.Columns.Add(colMenu);        
         

        
//绑定数据源
        this.SPGridView1.DataSourceID = "ExampleSource";
        
this.SPGridView1.DataBind();             
    }

注意:此代码要正常运行,测试用的列表必须有标题和Origin两个字段。
除了用代码给SPGridView添加字段,适应于GridView的一切手段都是可以应用到SPGridView的,
比如,你可以添加一个模板字段(TemplateFiled),模板内容当然可以按需控制了。
