过滤列表文档

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                    }
 41                    else
 42                    {
 43                        ((LinkButton)this.FindControl(Request["FitlerString"])).ForeColor = System.Drawing.Color.Red;
 44                    }
 45                });
 46            }
 47            catch
 48            {
 49    
 50            }
 51            finally
 52            {
 53                mySite = null;
 54                myWeb = null;
 55    
 56            }    
 57        }
 58    }
 59      protected   void  LinkButton_Click( object  sender, EventArgs e)
 60      {
 61        LinkButton tempButton = (LinkButton)sender;
 62        SPSite mySite = null;
 63        SPWeb myWeb = null;
 64        try
 65        {
 66            SPSecurity.RunWithElevatedPrivileges(delegate()

 70                myWeb.AllowUnsafeUpdates = true;
 71
 72                SPList oList = myWeb.Lists["Image & Video Library"];
 73                SPView oView = oList.Views["AegisCompany"];
 74                if (tempButton.CommandName != "ALL")
 75                {
 76                    oView.Query = "<Where><BeginsWith><FieldRef Name=\"FileLeafRef\" />" +
 77                    "<Value Type=\"Text\">" + tempButton.CommandName + "</Value></BeginsWith></Where>";
 78                }
 79                else
 80                {
 81                    oView.Query = "";
 82                }
 83                oView.Update();
 84                myWeb.AllowUnsafeUpdates = false;                
 85            });
 86        }
 87        catch
 88        {
 89        }
 90        finally
 91        {
 92            mySite = null;
 93            myWeb = null;
