我有一个日历控件，我正在填充不同的事件。当一个事件只跨越一天时，我希望它将链接按钮颜色更改为红色。

 public partial class RequestCalander : System.Web.UI.Page
{
    private DataSet GetData()
    {
        ConnectionStringSettingsCollection cssc = ConfigurationManager.ConnectionStrings;

        var sql = "select (substring(status, 1,1)) AS stat1, lastname, firstname, lstdate, lenddate, requestid from [table] E inner join [tableEvent] T on E.EMPID = T.emppid where E.depdivid = '" + @UsrDepartment + "'";

        using (iDB2Connection conn = new iDB2Connection(GetConnectionString()))
        {
            conn.Open();

            using (iDB2Command cmd = new iDB2Command(sql, conn))
            {
                cmd.DeriveParameters();

                using (iDB2DataAdapter da = new iDB2DataAdapter(cmd))
                {
                    DataSet ds = new DataSet();
                    da.Fill(ds);

                    return ds;
                }
            }
        }
    }

    private String GetConnectionString()
    {
        ConnectionStringSettingsCollection cssc = ConfigurationManager.ConnectionStrings;

        return cssc["connStringEvent"].ToString();
    }

    protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
    {
        e.Cell.Width = 150;
        e.Cell.Height = 100;
        DataSet ds = GetData();

        string link = "<a class='turnred' href='viewRequestForm.aspx?bwrequestid=";

        string s = e.Day.Date.ToShortDateString();

        e.Cell.Text = e.Day.Date.Day.ToString() + "<BR>";

        LiteralControl l = new LiteralControl();
        l.Text = e.Day.Date.Day.ToString() + "<BR>";
        e.Cell.Controls.Add(l);

        foreach (DataRow row in ds.Tables[0].Rows)
        {
            string scheduledDate = Convert.ToDateTime(row["lstdate"]).ToShortDateString();
            string endDate = Convert.ToDateTime(row["lenddate"]).ToShortDateString();

            e.Cell.Width = 120;
            e.Cell.Height = 100;

            Int32 start = 0;
            Int32 end = 0;

            start = string.CompareOrdinal(scheduledDate, s);
            end = string.CompareOrdinal(endDate, s);

            if ((start > 0) || (end < 0) || (e.Day.IsWeekend == true))
            {
                return;
            }

            HyperLink hl = new HyperLink();
            hl.Text = "yes";

            if (scheduledDate.CompareTo(endDate) == 0){
                    hl.ForeColor = System.Drawing.Color.Red;

                e.Cell.Controls.Add(hl);
               }
                if ((start <= 0) & (end >= 0) & (!e.Day.IsWeekend))
                {
                    HyperLink lb = new HyperLink();
                    lb.Text = link + (Int64)row["bwrequestid"] + "' >" + row["lastname"] + "</a>" as String + "(" + row["stat1"] + ")" as String + "<br />";
                    lb.ForeColor = System.Drawing.Color.Red;
                    e.Cell.Controls.Add(lb);
                    lb.NavigateUrl = "~/Form.aspx?requestid={0}";
    }

您可能需要进一步描述您的代码，但这是我最初的想法。

代码前端

<style type="text/css">
    .disabledbtn { color: Red; }
</style>

<asp:Calendar ID="Calendar1" runat="server" ondayrender="Calendar1_DayRender" Font-Size="Large" Width="901px" style="font-family: 'Times New Roman', Times, serif" >
    <TitleStyle Font-Bold="true" Font-Size="X-large" BorderStyle="Solid" />
    <DayHeaderStyle CssClass="caldays" Height="30px" BorderStyle="Solid" />
    <DayStyle CssClass="calcurrentmonth" Font-Size="X-small" Height="100px" />
    <TodayDayStyle CssClass="calcurrentday" Width="120px" Height="100px"/>
    <WeekendDayStyle CssClass="calweekend" Width="120px" Height="100px"/>
    <OtherMonthDayStyle CssClass="calothermonth" Width="120px" Height="100px"/>
</asp:Calendar>

背后的代码

问题是您正在创建两个链接。一个没有任何链接文本，设置为红色，第二个具有名称和状态。

您永远不会看到红色文本，因为它没有要显示的文本。我已经稍微简化了您的代码，现在它可以在我的末端运行。

这是我为测试而创建的假货DataSet，但您的应该代替它。

private DataSet GetData()
{
    // create a test data set
    DataTable dt = new DataTable();
    dt.Columns.Add("stat1");
    dt.Columns.Add("lastname");
    dt.Columns.Add("firstname");
    dt.Columns.Add("lstdate");
    dt.Columns.Add("lenddate");
    dt.Columns.Add("bwrequestid");

    dt.Rows.Add("P", "Doe", "John", "08/16/2012", "08/16/2012", 1);
    dt.Rows.Add("P", "Doe", "Jane", "08/14/2012", "08/17/2012", 2);
    dt.Rows.Add("C", "Black", "Jack", "08/12/2012", "08/12/2012", 3);
    dt.Rows.Add("C", "Morgan", "Dexter", "08/01/2012", "08/07/2012", 4);
    dt.Rows.Add("S", "Swearengen", "Al", "08/15/2012", "08/20/2012", 5);
    dt.Rows.Add("S", "Kirk", "James T", "08/04/2012", "08/04/2012", 6);
    dt.Rows.Add("P", "Bundy", "Al", "08/07/2012", "08/07/2012", 7);

    DataSet ds = new DataSet();
    ds.Tables.Add(dt);

    return ds;
}

我相信这应该正确呈现您的日历。我不确定的一件事，你想让周末约会总是红色吗？

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
    e.Cell.Width = 150;
    e.Cell.Height = 100;
    DataSet ds = GetData();

    foreach (DataRow row in ds.Tables[0].Rows)
    {
        DateTime scheduledDate = Convert.ToDateTime(row["lstdate"]);
        DateTime endDate = Convert.ToDateTime(row["lenddate"]);

        // make sure it meets your criteria
        if ((e.Day.Date >= scheduledDate && e.Day.Date <= endDate))
        {
            // create the hyperlink
            HyperLink hl = new HyperLink();
            hl.Text = "<br />" + row["lastname"].ToString() + "(" + row["stat1"].ToString() + ")";
            hl.NavigateUrl = "~/Form.aspx?requestid=" + row["bwrequestid"].ToString();

            // if the start and end dates are the same day, make it red
            if (scheduledDate.CompareTo(endDate) == 0)
                hl.CssClass = "changecolor";

            // add control to cell
            e.Cell.Controls.Add(hl);
        }
    }
}

更新这是带有新代码的输出。
