Requirement：

   最近客户在列表文档库中上传了多很文档，如果他们需要看一个文档，要翻很多页才能找到，他们希望用A.B.C...Z 字母开头的进行过滤。当点A的时候，显示A开头的所有文档。

 

 

 

Solution:

   我想要实现这种功能有很多种方法，下面我给大家介绍我如何实现的这个功能。

 

    step1,我创建了一个叫Brand的View，这个 view专门来过滤文档的。

 

    step2,添加一个quickpart 容器webpart,用他来包装我们开发的过滤用户控件。

 

    User Control代码 如下：

 

    

  1<%@ Control Language="C#" Debug="true" %>
  2<%@ Import Namespace="Microsoft.SharePoint" %>
  3<%@ Import Namespace="System.Data"  %>
  4
  5<script runat="server">
  6    string redirectUrl="/BizDevMarketing/ImageVideoLibrary/Forms/AegisCompany.aspx?RootFolder=%2FBizDevMarketing%2FImageVideoLibrary%2FAegis%20Company%20Logos";
  7    protected void Page_Load(object sender, EventArgs e)
  8    {
  9        if (!IsPostBack)
 10        {
 11            SPSite mySite = null;
 12            SPWeb myWeb = null;
 13            try
 14            {
 15                SPSecurity.RunWithElevatedPrivileges(delegate()
 16                {
 17                    mySite = new SPSite(SPContext.Current.Site.ID);
 18                    myWeb = mySite.OpenWeb(SPContext.Current.Web.ID);
 19    
 20                    SPList oList = myWeb.Lists["Image & Video Library"];
 21                    SPView oView = oList.Views["AegisCompany"];
 22    
 23                    if (string.IsNullOrEmpty(this.Request["FitlerString"]))
 24                    {
 25                        if (!string.IsNullOrEmpty(oView.Query))
 26                        {
 27                            myWeb.AllowUnsafeUpdates = true;
 28                            oView.Query = "";
 29                            oView.Update();
 30                            myWeb.AllowUnsafeUpdates = false;
 31    
 32                            mySite = null;
 33                            myWeb = null;
 34                            this.Response.Redirect(redirectUrl, true);
 35                        }
 36                        else
 37                        {
 38                            All.ForeColor = System.Drawing.Color.Red;
 39                        }
 40                    }

 45                });

 55    
 56            }    
 57        }
 58    }
 59    protected void LinkButton_Click(object sender, EventArgs e)
 60    {
 61        LinkButton tempButton = (LinkButton)sender;
