SharePoint 自定义日历
4.40/5 (4投票s)
根据自定义 SharePoint 列表显示个性化节假日/公告
引言
最近我的公司决定在员工门户上托管一个标准日历来显示节假日，但条件是日历应该显示人力资源部门希望员工了解的节假日/信息/更新，他们不想使用公告 Web 部件。
问题
我们希望在 SharePoint 内网中显示一个传统的日历作为 Web 部件，并具有以工具提示形式为每一天显示自定义信息的特性。这些自定义信息是从带有英文和中文文本的 SharePoint 自定义列表中显示的。
先决条件
此 Web 部件基于一个自定义 SharePoint 列表，并为其预定义了列才能正常工作。因此，在 SharePoint 中创建一个具有以下站点列的自定义列表
| 显示名称 | 内部名称 | 类型 | 目的 |
| 标题 | 标题 | 单行文本 | 用英文显示节假日/公告 |
| 节假日日期 | Holiday_x0020_Date | 日期时间（仅日期） | 要渲染的日期。 |
| TitleInChinese | TitleInChinese | 单行文本 | 用中文显示节假日/公告 |
| Location | Location | 单行文本 | 地点（在我的例子中是香港、澳门、中国） |
日历
此 Web 部件基于标准的 System.Web.UI.WebControls.Calendar 控件，因此该控件没有什么特别之处。但是，为了渲染带有列表的日期，我们必须重写 OnDayRender() 事件。
public class MyCalander: System.Web.UI.WebControls.Calander
{
MyWebPart oParent;
public MyCalander(MyWebPart oCurrentParent)
{
this.oParent = oCurrentParent;
}
protected override void OnDayRender(TableCell cell, CalendarDay day)
{
try
{
// This Day is rendered as a Table Cell "<TD>"
cell.ToolTip = String.Empty;
// The oParent is the parent object with all
// the properties passed when creating instance of this class.
cell.BorderWidth = new Unit(oParent.calBorderWidth);
if (day.IsToday)
{
cell.Font.Bold = true;
cell.BackColor = Color.FromKnownColor(oParent.calTodayBackColor);
cell.ForeColor = Color.FromKnownColor(oParent.calTodayForeColor);
}
if (day.IsWeekend)
{
cell.BackColor = Color.FromKnownColor(oParent.calWeekEndBackColor);
cell.ForeColor = Color.FromKnownColor(oParent.calWeekEndForeColor);
}
if (day.IsOtherMonth)
{
cell.BackColor = Color.FromKnownColor(oParent.calRestDayBackColor);
cell.ForeColor = Color.FromKnownColor(oParent.calRestDayForeColor);
}
if (this.HolidayScheduleListName == null ||
this.HolidayScheduleListName == String.Empty)
{
return;
}
SPWeb web = SPControl.GetContextWeb(this.Context);
SPSite siteCollection = SPContext.Current.Site;
SPList calendarList =
siteCollection.RootWeb.Lists[HolidayScheduleListName];
// DEFAULT TO Holiday_x0020_Date if the user has not
// provided with a exact column name.
if (oParent.HolidayDateFilterSiteColumn == null ||
oParent.HolidayDateFilterSiteColumn == "")
oParent.HolidayDateFilterSiteColumn = "Holiday_x0020_Date";
// Now check if the column exists on the list.
if (!calendarList.Fields.ContainsField
(oParent.HolidayDateFilterSiteColumn))
{
CalendarWebPart.LogMessage
(oParent.HolidayDateFilterSiteColumn + " site column not found.");
return;
}
SPQuery query = new SPQuery();
query.ExpandRecurrence = true;
query.Query = "<Where><And><Eq><FieldRef Name='"
+oParent.HolidayDateFilterSiteColumn+"'/>
<Value Type='DateTime'>" + day.Date.ToString("yyyy-MM-dd") +
"T00:00:00Z</Value></Eq>";
query.Query += "<Eq><FieldRef Name='Location'/><Value Type='Text'>" +
oParent.strLocation + "</Value></Eq>";
query.Query += "</And></Where>";
try
{
SPListItemCollection spHolidays = calendarList.GetItems(query);
foreach (SPListItem oItem in spHolidays)
{
/*
* Check if the web language is 1033 - English.
*/
if (web.Language.ToString() == "1033") cell.ToolTip =
oItem["Title"].ToString();
else oItem["TitleInChinese"].ToString();
cell.BackColor = Color.FromKnownColor(oParent.calHolidayBackColor);
cell.ForeColor = Color.FromKnownColor(oParent.calHolidayForeColor);
}
}
catch (Exception innerException)
{
// I am not throwing an error here as this is an
// exception on List; don't want to spoil user experience
// so I will go ahead and draw the day.
CalendarWebPart.LogMessage(innerException.Message);
}
}
catch (Exception e)
{
// Now this is a NASTY ERROR, Stop processing and scare the user....
CalendarWebPart.LogMessage(e.Message);
throw e;
}
}
列表查询
OnDayRender() 的关键部分是 SPQuery。
// SELECT Title, TitleInChinese From HolidayList WHERE
// Holiday_x0020_Date = Date_of_DayRendered
// This converts to the SPQuery as :
<Where>
<And>
<Eq>
<FieldRef Name='Holiday_x0020_Date'/><Value Type='DateTime'>
01/01/2010T00:00:00Z</Value>
</Eq>
<Eq>
<FieldRef Name='Location'/><Value Type='Text'>Hong Kong</Value>
</Eq>
</And>
</Where>
要使用 DISTINCT 值构建下拉列表，请创建一个 DataView 并将 listitems 转换为 DataTable。
要从列表中获取 DISTINCT 值；使用 SPListItemCollection.GetDataTable 方法并使用 System.Data.DataView.ToTable() 方法转换为 DataTable。
SPQuery query = new SPQuery();
query.Query = "<OrderBy><FieldRef Name='Location'/></OrderBy>"
query.ViewFields = "<FieldRef Name='Location' />";
// SPListItemCollection.GetDataTable() converts
DataTable tblUnique = new DataView
(calendarList.GetItems(query).GetDataTable()).ToTable(true, "Location");
//Now tblUnique contains all the Unique Values from the SharePoint Custom Lists.
Web 部件参数：颜色
主要问题是整个 Web 部件的外观和感觉，因为它必须与当前主题融合。因此，简单的方法是向 Web 管理员提供一个 String 对象，他可以在其中输入 #ffffff 颜色代码，或者提供一个包含颜色名称的下拉列表。
此解决方案是使用 System.Drawing.KnownColor enum 并使用 Color.FromKnownColor() 将 KnownColor 转换为 Color。
#region Calendar.Title.BackColor
private KnownColor TitleBackColor = KnownColor.Black;
/// <summary>
/// Title Back Color
/// </summary>
[Personalizable(PersonalizationScope.User),
WebBrowsable(true),
WebDisplayName("Title Back Color"),
WebDescription("Enter a color value"),
Category("Look & Feel"),
FriendlyName("Title Back Color"),
XmlElement(typeof(System.Drawing.KnownColor))]
public KnownColor calTitleBackColor
{
get { return TitleBackColor; }
set { TitleBackColor = value; }
}
#endregion
下拉列表的回调
痛点是从客户端生成 OnSelectionChanged() 触发器，以便可以刷新 Web 部件。最简单的方法是在客户端编写一个 Java 函数来使用 SelectedItemText: 进行回调。
protected override void OnPreRender(EventArgs e)
{
try
{
base.OnPreRender(e);
/*
* I need to spit out client side code to get an
* injection for change in dropdown values.
*/
if (!Page.ClientScript.IsClientScriptBlockRegistered("OnChangeDD"))
{
String script = @"function dl_onchange() {
var dl=document.getElementById('" + ddlLocation.ClientID + @"');
var url = document.URL;
if (url.indexOf('?') > 0) url = url.substr(0, url.indexOf('?'));
document.location= url + '?Location='+dl.value;}";
Page.ClientScript.RegisterClientScriptBlock(typeof(Page),
"OnChangeDD", script, true);
}
if (HttpContext.Current.Request.QueryString.Count > 0)
{
this.strLocation = HttpContext.Current.Request.QueryString
["Location"];
}
// Now that I am about to vomit the HTML
// (yup after all its HTML) - Load the DropDown with values.
this.getListItems();
cal.RefreshControl(this); // Same do it for the calendar.
}
catch (Exception ex)
{
// This is a Static Method to log errors in Event Viewer
CalendarWebPart.LogMessage(ex.Message);
throw ex;
}
