我正在尝试创建一个日历，它只是一个简单的 UI，用于向我们系统的用户显示日期和日期。我重写了日历的“DayRender”事件以访问每个单元格，然后插入几个动态控件来显示特定数据。控件的显示效果很好。但是，我最近想添加一个带有命令参数的 LinkBut​​ton 并捕获事件以运行其他一些逻辑并更改 UI。我已经让 LinkBut​​ton 正确显示，它呈现为带有分配 ID 的简单“”标签。但是，单击该链接没有任何作用，并且似乎没有生成链接的正常“href='...javascript action...'”部分。我有一种感觉，这都是因为我在页面生命周期的 Day Render 阶段添加了控件。但如果是这种情况，控件可能根本不会出现。

关于为什么没有添加点击动作但文本和其他所有内容的任何想法？代码如下。

谢谢你的时间

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
    {
        if (Schedule != null)
        {
            var dayReq = from day in Schedule
                         where day.RequiredDate == e.Day.Date
                         where day.RequiredQty != 0
                         select day;

            if (dayReq.FirstOrDefault() != null)
            {
                //Open the Date
                e.Cell.Controls.Add(new LiteralControl("<br /><div class=\"auth-sched-req\">Req Qty: <strong>" + String.Format("{0:#,#.###}", dayReq.FirstOrDefault().RequiredQty) + "</strong><br />Prom Date: "));

                //Create a link button for the promise date
                LinkButton lb = new LinkButton();
                lb.ID = dayReq.FirstOrDefault().ItemId.ToString();
                lb.Text = dayReq.FirstOrDefault().RequiredDate.ToShortDateString();
                lb.CommandName = "ShowPromise";
                lb.CommandArgument = dayReq.FirstOrDefault().ItemId.ToString();
                lb.Command +=new CommandEventHandler(lb_Command);
                e.Cell.Controls.Add(lb);

                //Close the Date
                e.Cell.Controls.Add(new LiteralControl("</div>"));
            }
        }
    }

    protected void lb_Command(Object sender, CommandEventArgs e)
    {
        //Do some magic here
        Response.Write(e.CommandArgument.ToString());
    }

I ended up going another route with this request. None of the proposed solutions worked and I never could get it to work. One option we looked at was creating a custom table to build the control. We ended up changing where the information was changed and just used the calendar control as the display mechanism.

Sorry for the delay!

检查 AutoEventWireup 是否设置为 true 即

AutoEventWireup="true"

尝试这个

<script type="text/javascript">
    function calendarClick(day) {
        document.getElementById('<%= hfValue.ClientID %>').value = day;
        document.getElementById('<%= ghostButton.ClientID %>').click();
    }
</script>
<asp:Button ID="ghostButton" runat="server" Style="display: none" OnClick="ghostButton_Click" />
<asp:HiddenField ID="hfValue" runat="server" />

后面的代码：

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
    // ...
    e.Cell.Attributes["onclick"] = string.Format("calendarClick({0})", dayReq.FirstOrDefault().ItemId.ToString());
    // ...
}
protected void ghostButton_Click(object sender, EventArgs e1)
{
    string value = hfValue.Value;
    // ...
}
