有没有更简单的方法在 asp:Calendar 控件中显示周数?我找到了这篇文章,但它是 2008 年的帖子。认为现在可能有更简单的方法吗?
我正在使用 asp.net c# 4.0 进行开发。
谢谢
您可以使用该DayRender
事件并将星期数添加到单元格中:
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
int weeknum = CultureInfo.CurrentCulture.Calendar.GetWeekOfYear(
e.Day.Date,
CultureInfo.CurrentCulture.DateTimeFormat.CalendarWeekRule,
CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek
);
e.Cell.Controls.Add(new LiteralControl(string.Format("({0})", weeknum)));
}
如果这还不够可爱,因为它总是将星期数添加到单元格中,请使用您的链接。
相同的语法应该仍然有效。请记住,不同文化中的周计算方式不同,如果您看到第 53 周,则没有错误!
using System.Globalization;
CultureInfo cultInfo = CultureInfo.CurrentCulture;
int weekNumNow = cultInfo.Calendar.GetWeekOfYear(DateTime.Now,
cultInfo.DateTimeFormat.CalendarWeekRule,
cultInfo.DateTimeFormat.FirstDayOfWeek);
我已经设法使该代码也可以更改周数,这是代码:
后面的代码:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
eventsDayView.DataLoad(DateTime.Now);
calendar.SelectedDate = DateTime.Now;
calendar.TodaysDate = DateTime.Now;
calendar.VisibleDate = DateTime.Today;
addWeekNumberColumn();
}
}
private void addWeekNumberColumn()
{
// Get the date shown in the calendar control
DateTime curMonth = calendar.VisibleDate;
// Find first day of the current month
curMonth = Convert.ToDateTime(curMonth.Year.ToString() + "-" + curMonth.Month.ToString() + "-01");
// Build javascript
string jscript = "<script type='text/javascript'> addWkColumn('" + calendar.ClientID + "', " + getISOWeek(curMonth).ToString() + ");</script>";
// Add script to page for execution of addWkColumn javascript function
Page.ClientScript.RegisterStartupScript(this.GetType(), "AddWeeknumbers", jscript);
}
// Helper function to find ISO week
private int getISOWeek(DateTime day)
{
return System.Globalization.CultureInfo.CurrentCulture.Calendar.GetWeekOfYear(day, System.Globalization.CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);
}
protected void calendar_OnVisibleMonthChanged(object sender, MonthChangedEventArgs e)
{
calendar.VisibleDate = e.NewDate;
addWeekNumberColumn();
}
ASP:
<script type="text/javascript">
function addWkColumn(tblId, wkStart) {
var tbl = document.getElementById(tblId);
var tblBodyObj = tbl.tBodies[0];
for (var i = 0; i < tblBodyObj.rows.length; i++) {
// Month Header
if (i == 0) {
// Add extra colspan column
tblBodyObj.rows[i].cells[0].colSpan = 8;
}
// Week Header
if (i == 1) {
// Add week column headline
var newCell = tblBodyObj.rows[i].insertCell(0);
newCell.innerHTML = 'wk';
newCell.style.fontSize = '8px';
newCell.style.fontWeight = 'bold';
newCell.style.verticalAlign = 'bottom';
newCell.style.backgroundColor = '#ffffee';
}
// Normal row
if (i >= 2) {
// Add the weeknumbers
var newCell = tblBodyObj.rows[i].insertCell(0);
newCell.innerHTML = wkStart;
wkStart += 1;
if (wkStart == 53) {
wkStart = 1;
}
newCell.style.fontSize = '8px';
newCell.style.backgroundColor = '#ffffee';
}
}
}
</script>
