如何在sharepoint增加自定义控件

背景：sharepoint的左侧快速链接不能满足我们的需要，我们需要根据登陆用户加载不同的菜单，根据用户的不同语言版本加载不同语言的左侧快速导航。

直接上控件代码：

public class CustomeMenu : WebControl
    {
        protected override void CreateChildControls()
        {
            base.CreateChildControls();
            Table table = new Table();
            table.CellPadding = 0;
            table.CellSpacing = 0;

            TableRow row_Menu = new TableRow();
            TableCell cell_Menu = new TableCell();
            cell_Menu.Text = "互联网";
            row_Menu.Cells.Add(cell_Menu);
            table.Rows.Add(row_Menu);

            TableRow row_Menu2 = new TableRow();
            TableCell cell_Menu2 = new TableCell();
            cell_Menu2.Text = "---百度";
            row_Menu2.Cells.Add(cell_Menu2);
            table.Rows.Add(row_Menu2);

            TableRow row_Menu3 = new TableRow();
            TableCell cell_Menu3 = new TableCell();
            cell_Menu3.Text = "---腾讯";
            row_Menu3.Cells.Add(cell_Menu3);
            table.Rows.Add(row_Menu3);

            TableRow row_Menu4 = new TableRow();
            TableCell cell_Menu4 = new TableCell();
            cell_Menu4.Text = "水果";
            row_Menu4.Cells.Add(cell_Menu4);
            table.Rows.Add(row_Menu4);

            TableRow row_Menu5 = new TableRow();
            TableCell cell_Menu5 = new TableCell();
            cell_Menu5.Text = "---苹果";
            row_Menu5.Cells.Add(cell_Menu5);
            table.Rows.Add(row_Menu5);

            TableRow row_Menu6 = new TableRow();
            TableCell cell_Menu6 = new TableCell();
            cell_Menu6.Text = "---桃子";
            row_Menu6.Cells.Add(cell_Menu6);
            table.Rows.Add(row_Menu6);

        }
    }

 将dll签名注册到GAC中，再修改web.config，将该控件加到安全控件中。

<SafeControl Assembly="ControlLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=590e3f83bda9d281" Namespace="ControlLibrary" TypeName="*" Safe="True" SafeAgainstScript="False" />

重启IIS，用Designer打开v4.master，将左侧导航隐藏。

<div style="display:none">
    <Sharepoint:SPNavigationManager
    id="QuickLaunchNavigationManager"
    runat="server"
    QuickLaunchControlId="QuickLaunchMenu"
    ContainedControl="QuickLaunch"
    EnableViewState="false"
    CssClass="ms-quicklaunch-navmgr">
    </div>

添加我们自己的自定义控件

<%@ Register Tagprefix="ControlLibrary" Namespace="ControlLibrary" Assembly="ControlLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=590e3f83bda9d281" %>

然后再<Sharepoint:SPNavigationManager>上面添加

<ControlLibrary:CustomeMenu runat="server"></ControlLibrary:CustomeMenu>

我们自定义控件就生成了。
