I building a custom user control in asp.net where the user can enter in a date. I am already using a JQuery function that puts in a date mask in the format of dd/mm/yyyy, but I am unable to find another JQuery function(s) or one that combines all my needs.
What I am also looking for is:
1) To validate whether the date is really a date, i.e. not 31/13/2010 or anything along those lines.
2) Where I can check to see whether a date is in the past or in future based upon a configuration entry in the application.
Can anyone help me, please?
This is just off the top of my head, but you could use JavaScript's Date object http://www.w3schools.com/jsref/jsref_obj_date.asp
1) You could use one of the following
var d = new Date(dateString);
var d = new Date(year, month, day, hours, minutes, seconds, milliseconds);
Then verify that the date components are the same as entered. If you set the month to 50, it will take the year, and go 50 months forward... which seems odd, but... Just have to verify the information is what you entered. The months start at 0 for January, so when checking, be aware of that.
2) There's probably a lot of ways to do this check, but a quick thought on it is
var t = d.getTime() - new Date().getTime();
If t is positive, it's in the future, if it's negative it's in the past.
The new Date() creates a date object with the current time.
You could also use the jQuery UI DatePicker. http://jqueryui.com/demos/datepicker/
I haven't checking into the exact functionality it has that might fit your requirement, but it is another resource to check into.

I'm trying to give my users the option to select the date field granularity of their choice, such as day, week, month or year. This is normally controlled on each graph in the menu show below but this isn't available in a published dashboard:
My first idea was to create a calculated field that truncates my desired date based on a parameter that I expose through a control. This would like something like this, truncDate(${intervalParameter}, {dateColumn}). The problem with this is that the first argument of the truncDate function must one of valid string literals and will throw an error before saving if it isn't.
Does anyone know of any other ways of achieving this? Or maybe some sneaky way of getting around the error?
I figured out a work around using ifElse.
ifElse(
${intervalParameter} = 'Day', truncDate("DD", {dateColumn}),
${intervalParameter} = 'Week', truncDate("WK", {dateColumn}),
${intervalParameter} = 'Month', truncDate("MM", {dateColumn}),
truncDate("DD", {dateColumn})
)
There might be better solutions out there but this is what I've come up with.
I have time for example I have in records time written in this way: 00:02:24 or 15:22:45, and now I want to make another column (hours), where can be values for example for time 02:43:22 is value 2, or for time 23:22:14, is value 23 and so on. But I don't know how can I do that, I tried number range, but unsuccessfully.
Here is a picture, how i want to be:
Thanks.
You can use the Modified JavaScript Value step.
I do not know which type is your Time.
If it is a String, a var Hour = Time.substr(0,2); will do.
If it is a Date, use var Hour = Time.getHour();.
If the type is something else, then convert in a String first.
To do this:
drag-and.drop the step Modified JavaScript Valueand link it to the data flow provider (in the example a Data grid).
edit this step and add your script. (Note that you can quickly add the input variable with a double click. Note also that clicking on the Transformation Function in the left menu gives you the list of available function additional to the Javascript built-in collection).
Click on the Get variable button, keep the variable you need (here Hour), and define/redefine its type (here String).
That's done: OK and preview.
If needed, adapt to the type of your input flow. For example Hour = Hour+'' to force a type conversion into a String.
I am using a Kendo spreadsheet to import data from an Excel file so I can plug it into an SQL Server database using Ajax callbacks. The Ajax callbacks work fine, but I have determined that any Date strings are being converted to an integer offset from a base date of 12/30/1899. I have submitted a support ticket to Telerik, but they do not seem to understand the problem.
The data is displayed in the Kendo spreadsheet appropriately as a date. Kendo converts a date input as "12/1/2015" to "12-1-2015".
I am using the latest version of the ASP.NET MVC 5 wrapper, but the JavaScript code is the 2016-1-226-545 version of the JavaScript. The wrapper version seems to be irrelevant, but later versions of the JavaScript have the gulpfile.js, and this conflicts with the Bundleconfig interface on my ASP.NET MVC 5 project, so I simply work with the last version of the JavaScript that works for my setup.
The spreadsheet I am working with is pretty basic to start:
#(
Html.Kendo().Spreadsheet()
.Name("SiteSlotDataSS")
.Rows(10)
.Columns(4).ColumnWidth(100)
.Sheets(sheets =>
{
sheets.Add()
.Name("Study Data");
}
)
)
I use the import option to pull in an Excel spreadsheet and use a simple button with a click event routine to copy the data to a string array to send to the Ajax callback. I have confirmed that the data being sent to the server controller is the same as it is on the client side before being sent. The Date conversion to an integer occurs when the values are extracted from the range.
The code in question that selects the values is:
values = sheet.range("A" + headerRows.toString() + ":" + endRange + (headerRows + rows).toString()).values();
This produces the correct translation of every other column except for columns containing dates.
I tried the following to brute-force the issue, without success:
for (var x = 0; x <= rows; x++) {
sheet.range("K" + (headerRows + x).toString()).format(kendo.spreadsheet.formatting.date);
}
I could try a date function to convert the date back into the original value, but everyone pretty much knows how Telerik's documentation is a bit skimpy and overall simply a nightmare to find answers to questions with.
What is the solution?
It appears that Kendo Spreadsheet stores the date values as an integer offset from 12/30/1899 in days. I determined the "0" value by entering a date of 1/1/1901 to see what came back, then 1/1/1900. The result of the latter was "2", making the base date 12/30/1899. Taking the data and converting it at the server seems to be the best option. I don't really expect much of a response from Telerik.
I have addressed the storage issue with Telerik, and they have acknowledged there is a bug in the spreadsheet widget.
For now, the solution is to bring the values array one row at a time back to the server and do the data conversion server-side. The integer that is returned in the values array for dates is the way the Kendo Spreadsheet stores the information client-side. Formatting the column simply will not do anything but change the client-side display. It will not change how Kendo returns the values matrix from the spreadsheet range selected.
Firstly, I think you mean 12/31/1899. It makes no sense to refer anything to 12/30/1899.
Excel dates start with 1/1/1900, just as do your Kendo (Japanese: "the way of the sword") dates. If you're getting an integer, forcibly coerce it to the corresponding date on the receiving by merely FORMATTING THE COLUMN. There is no need for a specific function to "convert" days-since-1900 counts to text dates (MM/DD/YYYY), as they are the SAME, differing only in human-readable representation.
Of course, it wasn't clear from your description whether Excel was on the input side or the output side of the problem.
I have a column called Start Time (it's a SharePoint Default Calendar Column). I need to validate if the Start Time is less than today or not? Without using javascript? Is this possible?
I have tried this:
Created a column called Today type as Date and Time.
Default value is current date.
Then compared the Start Time and Today in validation settings like the following:
=[Start Time] < [Today]
it seems not working. help please?
Try this code instead of yours
=[Start Time]<NOW()
I use this to validate that Start Date must be less than or equal to Today:
=[Start Date]<=Today()
...and it works for me.
CodeIgniter stores timezones for its date class in
system/language/english/date_lang.php
I would like to change the strings in this file so that
$lang['UM12'] = '(UTC -12:00) Baker/Howland Island';
$lang['UM11'] = '(UTC -11:00) Samoa Time Zone, Niue';
would instead be
$lang['-12:00'] = '(UTC -12:00) Baker/Howland Island';
$lang['-11:00'] = '(UTC -11:00) Samoa Time Zone, Niue';
Is this possible at all?
Any change I make to the UM__ portion of one line makes it show as a blank on the dropdown. The remaining (unchanged) lines appear OK.
I have also tried to clone this file to application/language/english/ with similar bad results.
Any insights on this?
It looks like this would require hacks to the date_helper.php file which I am not willing to do.
Instead, the date class in CI has the timezones() function which allows you to convert from, for example, UM5 to -5. In that case one can wrap this function around the U__ value coming from the view/dropdown -- and then save it to DB as -5 or some other INT.
Since I want to show the user their selected timezone on that same dropdown, I am forced to have DB fields for the U__ and INT timezone formats. As far as I know, there is no CI function to convert from -5 to UM5.
So, for the user, I pull the U__ format into the view to autopopulate the dropdown.
For timezone conversions and such, I use the INT format.
