Calendar Control - Programatically set the calendar to a date range

[Shevek]

Hi All, Hope someone can help!

I am building an Event Calendar app based around the Calendar
WebControl which builds an SQL string based on the SelectedDates
property which is passed to Page.StartDate and Page.EndDate
properties.

This works nicely and I can select a Day, Week or Month and run my SQL
against them.

There is also a shortcuts dropdown to allow the user to select Today,
Last Month, This Month, Next Month, Next Two Weeks, Next 30 Days, Next
60 Days, Next 90 Days.

Again, these all work nicely as I set the Page.StartDate and
Page.EndDate based on the option and run the SQL then update the
Calendar.Visibl eDate to Page.StartDate.

The problem is it would be nice for the Calendar object to reflect the
shortcut ranges. This is OK for Today as I can just set the
SelectedDate to the Page.StartDate. However the SelectedDates property
is read only.

Is there any way to set a range of dates to be selected based on the
Page.StartDate and Page.EndDate properties?

Many TIA

you can write a handler for DayRender event and check for the date and
change color accordingly.

private void Calendar1_DayRe nder(object
sender,System.W eb.UI.WebContro ls.DayRenderEve ntArgs e )
{
if (e.Day.Date >= Page.StartDate && e.Day.Date <= Page.EndDate)
{
e.Cell.BackColo r = System.Drawing. Color.LightGray ;
}
}

hth,
Av.

hth,
Doesn't quite work!

I already use the DayRender event to apply styles and onmouseover to
give the dates borders and rollovers.

If I change the first line to

If (e.Day.Date.ToS hortDateString >= Me.StartDate And
e.Day.Date.ToSh ortDateString <= Me.EndDate) or e.Day.IsSelecte d Then

then it seems to keep the cssclass in the viewstate and is there when
I browse back and forth through the calendar....
If e.Day.IsSelecte d Then
If bEvent Then
e.Cell.ApplySty le(ForeOrange)
e.Cell.CssClass = "EventSelectedD ay"
e.Cell.Attribut es.Add("onmouse over",
"javascript:thi s.className = 'EventSelectedD ayOver';")
e.Cell.Attribut es.Add("onmouse out",
"javascript:thi s.className = 'EventSelectedD ay';")
Else
e.Cell.CssClass = "SelectedDa y"
e.Cell.Attribut es.Add("onmouse over",
"javascript:thi s.className = 'SelectedDayOve r';")
e.Cell.Attribut es.Add("onmouse out",
"javascript:thi s.className = 'SelectedDay';" )
End If
ElseIf e.Day.IsWeekend Then

End If

e.Cell.CssClass = "EventOtherMont hDay"
e.Cell.Attribut es.Add("onmouse over",

e.Cell.Attribut es.Add("onmouse out",

Got it! It was not working because my Page.StartDate and Page.EndDate
are both dates stored as strings...

Dim dStartDate, dEndDate As Date
If IsDate(Me.Start Date) Then dStartDate = Me.StartDate
If IsDate(Me.EndDa te) Then dEndDate = Me.EndDate
If (e.Day.Date >= dStartDate And e.Day.Date <= dEndDate) Then

....has fixed it!

Cheers!
