I want to use the System.DateTime.Now() function (to get system time) rather than the Date() function (for user's time) in a Javascript routine of an ASP.net web page, however this does not seem to be supported in Javascript (as it is in VB.net).

I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)
[Code]....
Above is my code. The error I'm get is, Unable to cast object of type 'System.DateTime' to type 'System.String'.
The column "To" and column "Subject" are strings and column "Receive" is DateTime. I can't made any changes in the database, so I need to write some code to handle casting a string to datetime or if statement as a work around.

I was working on an attendance system on ASP.Net where the entire week's dates are calculated by my program based on the current date. I am using DateTime.Today. I was apprehensive to use this as I feel that users can modify this date by merely changing their system clock and mark previous week's attendance.Can DateTime.Today be changed by changing system clock on client side? If yes, is there something else I can use instead of that?
View 4 RepliesI am trying to parse out the date in datetime function. For example, I have 1/2/2010 and would like to parse out the day, month and year into different variables.
sDatetime = 1/2/2010
sDay = 1
sMonth = 2
sYear= 2010. Also I would like the day to be shown as 01 not just "1".
I am thinking to have a standardize date format for all the Date Time in the system when display to user and also for user input.For example YYYY-mm-DD HH:mm:ss .Does the Standardize date format for date timewill cause error by different clent local pc date format?The way i capture the datetime format from user input is :
dim dteDateTime as DateTime
dteDateTime=txtDateTime.tex
If the above format is not correct?Does anyone has idea on the correct way to standarize the Date Time format for all the ASP.NET system?

It is working fine in pre prod deployed site, but when I copy paste the same deployed code to the production I am getting below error:
System.FormatException: String was not recognized as a valid DateTime.
Am I going to be able to query (using LINQ to SQL) a database field with a type like the following "public System.Nullable<System.DateTime> Spouse_DOB"?
I'm trying to use the following code: [Code]....
and I get the error "'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)"
Is it because this DateTime column allows a NULL value (since everyone isn't married in my database)?
Error 1 'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)

FROM sessioncalendar

AND MONTH ( Date )= '6'
AS the query works well wethout addind AND MONTH ( Date )= '6' ... but when i add this line query generate error
( Error in list of function arguments: ')' not recognized. Unable to parse query text.)
While same query is working successfully with Sql Server 2005...but i hvnt found any reason why my query is not working with Date(datetime) column..i hv google about it..but i found synatax is same in both SQL SErver 2005 and MY SQL syntax
I am trying to replace the JavaScript onclick event handler in ASP.NET that is added to a button control when using validation controls. This is what is output into the HTML from ASP.NET in this scenario:
<input type="image" name="ibSubmit1" id="ibSubmit1" src="button-green-submit.gif" onclick="showProgress1();WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ibSubmit1", "", true, "Group1", "", false, false))" style="border-width:0px;" />
I have looked pretty estensively, and unfortunately there doesn't seem to be a way to modify the function server side before it is injected into the page.
Since I am developing a control and desire it to be non-invasive and self contained, and I am interested in obtaining the validationGroup parameter of the WebForm_PostBackOptions object, it seems that the easiest solution would be to use JavaScript to replace the WebForm_DoPostBackWithOptions function name with my custom wrapper function and leave all of the rest of the parameter information intact - then I can extract the information I am interested in, call my custom functions, and then forward the call on to WebForm_DoPostBackWithOptions.
NOTE: I am using jQuery to build my custom function, so if there is an easier way to do this with jQuery it is an option I will consider.
Here is the code I tried to replace the onclick event handler (not working):
$('[onclick*=WebForm_DoPostBackWithOptions]').each(function() {
var txt = this.onclick;
txt = txt + '';
txt = txt.replace('WebForm_DoPostBackWithOptions','ml_DoPostBackWithOptions');
this.onclick = eval(txt);
});
Using alert(), I verified that the text is being changed correctly, however whether or not I use the eval() function, the onclick handler doesn't seem to recognize it as JavaScript.
I thought of using a regular expression to get the validationGroup value, but this seems like it will be far more elegant and flexible if I can get it working...
Note: If there is a way for my control to interrogate the page it is on to find all of the buttons that will post back (regardless of what type of buttons they are) so I can retrieve the property server-side, this is also something I will consider.
In asp.net page, How can i call the javascript methods for form processing-submitting if the user browser supports javascript and use code behind events if the browser does not support javascript.I have the javascript code to send the form data to an ajax server page using jquery.

View 1 RepliesI have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">

However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...

And I also tried with a normal DateTime instead of a nullable one. If I put in a date which is not possible then it still shows as valid. How can I achieve validation, both server side as with unobtrusive client validation?
