我有一个日历控件，其中填充了不同的事件。当一个事件只持续一天时，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}";
}
}

最佳答案
您可能需要进一步描述您的代码，但这是我的初步想法。
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>
代码隐藏
问题是您创建了两个链接。一个没有任何链接文本，设置为红色，另一个有名称和状态。
您永远不会看到红色文本，因为它没有可显示的文本。我稍微简化了您的代码，现在可以在我这边运行了。
这是我创建的用于测试的假 DataSet，但您的应该取代它。
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;
}
我相信这应该可以正确呈现您的日历。有一件事我不确定，你希望周末约会总是是红色的吗？
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。
