Introduction:

Here I will explain how to set jQuery validation like end date should be greater than start date and allow user to select dates only within particular dates range using jquery datepicker control in asp.net.

Description:

In previous post I explained many articles relating to JQuery Datepicker in asp.net. Now I will explain how to set end date is greater than start date in jquery datepicker control using asp.net.

Sometimes we will get situation like allow user to enter start date, end date and end date should be greater than start date and another thing if we want to allow user to select only within 1 week or 10 days or 15 days or 1 month range we can set these things easily with set month/year range in JQuery datepicker. If we want to implement this one using Ajax calendar control we need to write much code in that case if we use JQuery datepicker control we can make it easily by setting some properties.

To implement this one first open Visual Studio and create new website after that write following code in your aspx page

<head>

<title>jQuery UI Datepicker - Select a Date Range</title>

$(function() {

var dates = $("#txtFrom, #txtTo").datepicker({

minDate: '0',

maxDate: '+7D',

onSelect: function(selectedDate) {

var option = this.id == "txtFrom" ? "minDate" : "maxDate",

instance = $(this).data("datepicker"),

date = $.datepicker.parseDate(

instance.settings.dateFormat ||

$.datepicker._defaults.dateFormat,

selectedDate, instance.settings);

dates.not(this).datepicker("option", option, date);

}

});

</script>

.ui-datepicker { font-size:8pt !important}

</style>

</head>

<body>

<asp:TextBox ID="txtFrom" runat="server"/>

<asp:TextBox ID="txtTo" runat="server"/>

</div>

</form>

</body>

</html>

If you observe above code in header section I added some of script files and css classes by using those files we will display calendar control with beautiful css style. You can get those files by downloading attached sample.

If you observe script in header section

$(function() {

var dates = $("#txtFrom, #txtTo").datepicker({

minDate: '0',

maxDate: '+7D',

minDate: I set it as 0 means it won’t allow us to select before today date

maxDate: Here I set as '+7D' means it will allow us to select upto maximum 7 days.

If we want to set to 15 days or 1 Month range then we will use '+15D' or '+1M'

After completion of aspx page design and your code modifications just run your application and check your calendar control that would be like below demo
