Ajax CalendarExtendar: I found many questions on different sites regarding date range selection in Ajax CalendarExtender, while it is quite simple to bound the range to select from, you can allow all the dates, disable past dates, disable date greater than current date, date should be greater than current date + 1 month, current date to 1 month etc.
So let me explain one by one:
For all dates
It's default behavior of Ajax CalendarExtender so no need to add any start or end date, here is the code
<ajax:CalendarExtender ID="CalendarExtender1" runat="server"
TargetControlID="txtSateDate"
PopupButtonID="imgSateDate"
CssClass=".cal_Calendar" />
For date greater than to year 2012
It means date should be greater than 01/01/2012, right.
Simply add StartDate = "01/01/2012", here is the code:
<ajax:CalendarExtender ID="CalendarExtender1" runat="server"
TargetControlID="txtSateDate"
PopupButtonID="imgSateDate"
StartDate = "01/01/2012"
CssClass=".cal_Calendar" />
For date range If you want to define the minimum and maximum date then use StartDate as well as EndDate, for example from 01/01/2012 to 12/31/2020, here is the code:
<ajax:CalendarExtender ID="CalendarExtender1" runat="server"
TargetControlID="txtSateDate"
PopupButtonID="imgSateDate"
StartDate = "01/01/2012"
EndDate = "12/31/2020"
CssClass=".cal_Calendar" />
Till now we discussed how to use the fixed date, from a particular date to a particular date, suppose I want to allow to select a date which can be greater than equal to current date but can not be more than one month. In that case we can not use the hard coded date but we would have to write the code in our code behind file: In Page_Load method define the start date and end date
protected void Page_Load(object sender, EventArgs e)
{
CalendarExtender1.StartDate = DateTime.Today;
CalendarExtender1.EndDate = DateTime.Today.AddMonths(1);
}
We discussed how to disable dates, we are fine till now but when you will run the application and open the calender it will work fine as you have defined but no indication which dates are enabled and which are disabled. So we need to fix our CSS so it can indicate the disabled dates. Let's do the CSS changes; If you will check your CSS file it will have these lines there:
.cal_Calendar .ajax__calendar_title,
.cal_Calendar .ajax__calendar_next,
.cal_Calendar .ajax__calendar_prev
{
color: #004080;
padding-top: 3px;
}
Add one more line on the top
.cal_Calendar .ajax_calendar_invalid .ajax_calendar_day,
/* Add class for your Invalid dates*/
.ajax_calendar_invalid
{
color:red; text-decoration:strike; cursor:pointer;
}
And now refresh the page and open the calendar, it will look like this:
In some case we need to show only date and month say 05/21 or month and year say 07/2012 so is there any way that whatever date use is selecting show only date and month or month and year?, yes, we need to use format property to adjust our requirement and format.
// For date and month only
// For Month and year only
<ajax:CalendarExtender ID="CalendarExtender1" runat="server"
TargetControlID="txtSateDate"
PopupButtonID="imgSateDate"
Format = "MM/yyyy"
CssClass=".cal_Calendar" />
After setting the format, once we will select any date, it will so only dd/MM or MM/yyyy in our associated text boxes.
If you are using jQuery date picker then see MVC jQuery datepicker enable disable dates
