sharepoint 实现列表的插入，返回到本页的功能（利用现有控件重写按钮）

参考：http://www.cnblogs.com/jianyi0115/archive/2008/03/12/1102784.html

实现功能：点击按钮，实现列表插入，并返回到本页。

1.在屏幕上加入ListFormWebPart 控件

具体代码：

 

Code
<WebPartPages:ListFormWebPart runat="server" __MarkupType="xmlmarkup" WebPart="true" __WebPartId="{1ED682CA-5EA9-4206-A114-DB60F8A34F26}">
<WebPart xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://schemas.microsoft.com/WebPart/v2">
  <Title>评论</Title>
  <FrameType>None</FrameType>
  <Description />
  <IsIncluded>true</IsIncluded>
  <PartOrder>1</PartOrder>
  <FrameState>Normal</FrameState>
  <Height />
  <Width />
  <AllowRemove>true</AllowRemove>
  <AllowZoneChange>true</AllowZoneChange>
  <AllowMinimize>true</AllowMinimize>
  <AllowConnect>true</AllowConnect>
  <AllowEdit>true</AllowEdit>
  <AllowHide>true</AllowHide>
  <IsVisible>true</IsVisible>
  <DetailLink />
  <HelpLink />
  <HelpMode>Modeless</HelpMode>
  <Dir>Default</Dir>
  <PartImageSmall />
  <MissingAssembly>无法导入此 Web 部件。</MissingAssembly>
  <PartImageLarge />
  <IsIncludedFilter />
  <ExportControlledProperties>true</ExportControlledProperties>
  <ConnectionID>00000000-0000-0000-0000-000000000000</ConnectionID>
  <ID>g_1ed682ca_5ea9_4206_a114_db60f8a34f26</ID>
  <ListName xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">{AD6CF2C5-D352-4416-924F-FD2C1B86C35F}</ListName>
  <ListTitle xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">建议</ListTitle>
  <HideIfNoPermissions xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">true</HideIfNoPermissions>
  <ListItemId xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">0</ListItemId>
  <ControlMode xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">New</ControlMode>
  <DisableInitialFocus xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">true</DisableInitialFocus>
  <TemplateName xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">Tem_union3_narrow</TemplateName>
  <FormType xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">8</FormType>
  <ViewFlag xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">1048576</ViewFlag>
</WebPart>
</WebPartPages:ListFormWebPart>

 

注意修改一下你的 列表ID 也就是ListName 属性。

2.修改模板

大家注意到了TemplateName 这个属性，就是定制你的插入表单控件的模板 路径应该放到C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\template\controltemplates 里面

插入控件模板的具体代码是：

 

Code
<SharePoint:RenderingTemplate ID="Tem_union3_narrow" runat="server">
    <Template>
        <div class="union_title">标题：</div>
        <div>
            <SharePoint:TextField ID="textfield" runat="server" FieldName="Title" CssClass="union_Tem_text_narrow" />
        </div>
        <div class="union_title">内容：</div>
        <div>
            <SharePoint:NoteField ID="textfield1" runat="server" FieldName="WorkAddress"
                CssClass="union_Tem_text_narrow" />
        </div>
        <div>
            <div style="width: 100px; text-align:center;">
                <cc2:FormSaveButton ID="FormSaveButton1" runat="server" Text="提交" CssClass="button_narrow">
                </cc2:FormSaveButton>
            </div>
        </div>
        </div>
    </Template>
</SharePoint:RenderingTemplate>

3.重写按钮 大家注意到第二步

<cc2:FormSaveButton ID="FormSaveButton1" runat="server" Text="提交" CssClass="button_narrow"></cc2:FormSaveButton>

这个按钮就是重写的，具体方法：

 

Code
using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

using Microsoft.SharePoint;
using Microsoft.SharePoint.Security;
using System.Web.UI;
 
using Microsoft.SharePoint.WebControls;
using System.Security.Permissions;
using Microsoft.SharePoint.Utilities

namespace CodeArt.SharePoint
{
    /// <summary>
    /// 列表表单保存按钮，保存后返回本页面, 
    /// </summary>
    public class FormSaveButton : SaveButton
    {
        //return true stop event bubble
        //return false cotinue      
        protected override bool OnBubbleEvent(object source, EventArgs e)
        {
            this.Page.Validate();

            if (!this.Page.IsValid)
            {
                return true ;
            }
               //some valid code

            try
            {
                SaveData();
                return true ; 
            }
            catch (Exception ex)
            {               
                throw new SPException(ex.Message,ex);
            }

Page.Response.Redirect("/");

        }

        void SaveData()
        {            
            SPListItem listItem;

            if (this.ControlMode == SPControlMode.New)
                listItem = this.List.Items.Add();
            else
                listItem = this.ListItem;

            foreach (BaseFieldControl f in this.ItemContext.FormContext.FieldControlCollection)
            {
                try
                {
                      //some valid code here --if(f.FieldName="XX") do something

                    if (!f.Field.ReadOnlyField)
                        listItem[f.FieldName] = f.Value;
                }
                catch (ArgumentException) { }
            }

            listItem.Update();   
        }              
    }
}

4.如果一些步骤没错，就可以看到最终效果，插入列表的控件，和列表在一个界面，插入以后，列表更新，返回本页。

发图太麻烦，就不发了，希望对大家能有所帮助。
