I am trying the following code:
[Code]....
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?
I have a problem:
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)
Both samples have complete VB/C# project downloads. Please post comments/questions in this thread.http://www.asp.net/mvc/tutorials/creating-a-mvc-3-application-with-razor-and-unobtrusive-javascript
Walkthrough: Using TDD with ASP.NET MVC
I'm using the latest RC with asp.net mvc 3, and have turned on unobtrusive javascript validation and added the necessary scripts to the page. All of the validation works perfectly, but when I try to submit the page, it simply doesn't post. If I turn unobtrusive javascript off in the web.config without making any other changes, everything works perfectly fine.
Here's my scripts I'm using:
<script src="@Url.Content("~/Scripts/jquery-1.4.4.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
I'm passing a model to a view, and the model contains this attribute:
[Required(ErrorMessage = "Please enter a start date")]
[DataType(DataType.DateTime)]
[DisplayName("Start Date")]
public DateTime StartDate { get; set; }
And I have this in my view:
<%: Html.TextBoxFor(m => m.StartDate) %>
When I load the page, the textbox is populated with a date: 1/1/0001 12:00:00 AM
Is there a way to not have this happen, maybe by using metadata?
I'm using MVC 2 with some Models from a LinqToSql project that I built. I see that when I post back to a Controller Action after editing a form that has a DateTime field from the Model, the MVC Html.ValidationMessageFor() helper will nicely display an error beside the Date text box. This seems to happen automatically when the you test ModelState.IsValid() in the Controller Action, as if the MVC model binding automatically knows that the DateTime field cannot be empty.
My question is... I have some other string fields in these LinqToSql generated classes that are Not-Nullable (marked as Not Nullable in Sql Server which passes thourgh to the LinqToSql generated classes), so why doesn't Mr. MVC pick up on those as well and display a "Required" message in the ValidationMessageFor() placeholders I have added for those fields?
Sure, I have successfully added the MetadataType(typeof<t>) buddy classes to cover these Non-nullable string fields, but it sure does seem redundant to add all this metadata in buddy classes when the LinqToSql generated classes already contain enough info that MVC could sniff out. It MVC validation works with DateTime automatically, why not these Not-nullable fields too?
I have a sharepoint datetime control named date. Now how can i check whether the the field is empty or not;
i have the following code
if(date.ToString() != "")
{
lbl.Text = "Not Empty";
}
i did not enter any date in that field but the above code is always executed.
it always have the current date.
How can i assgin empty string to selectedDate propert of Sharepoint DateTime Control?
I make a partialView based "Detail-Edit" function as : 1 create two partial view : Details , Edit
2 in Details PartialView I render a link as "Ajax.ActionLink( .. "Edit" , AjaxOptions { get , updateTargetId="xx" , InsertMode="Replace" } )
3 in Edit PartialView I use "Ajax.BeginForm()" ...
As a result I can perfectly swith from Details view to Edit view in ajax manner ; however when I change to Edit mode in this approach, the "obtrusive js validation" loses its function that it can't prevent user from callback ajax even with invalid inputs. I think this is a common issue for MVC3 developers, could anyone help to give a standardized solution against this ? or any other valuable solutions ?In a word, just want to realize the traditional UpdatePanel-based "Edit,Details" effect on MVC mode with ajax .
I have asp.net form having 4 check boxes. not check box list. these 4 check boxes having the ValidationGroup property with same name say "chkValied". I have added Custom Validator there. now want to check at least on check box should be check out of these.

i included the table and its data as it would be impossible without that to understand. this is the meta scenario as you may notice that this was the query i wrote before when i was not checking the publish date
var postsidebar = from post in postrepository.GetAllPosts()
join pstmt in postrepository.GetAllPostMetas()
on post.int_PostId equals pstmt.int_PostId
where (post.int_PostTypeId == 4 && post.int_PostStatusId == 2 && post.int_OrganizationId == layoutrep.GetSidebarDetailById(SidebarDetailsId).int_OrganizationId)
&& (pstmt.vcr_MetaKey.Contains(filter) && pstmt.vcr_MetaValue.Contains("true"))
select post
how would i goint incoperate check for publish date in the query above( i want to bring all the records whose publish date is greater then todays date)

Group Validation of Two DateTime Picker Using Javascript in asp.net
View 1 Repliesi am using below code to print my content of webpage in asp.net using javascript
window.print(document.getElementById('dvPrint'));
when i do print, it automatically adds date time on page.. (i think because of page setup) in firefox. how can i remove this setting. i mean i dont want datetime to be printed automatically on my print page (even if its set in pagesetup).
I have a site that uses a jquery calendar to display events. I have noticed than when using the system from within IE (all versions) ASP.NET MVC will fail to bind the datetime to the action that send back the correct events. The sequence of events goes as follows. Calendar posts to server to get events Server ActionMethod accepts start and end date, automatically bound to datetime objects
In every browser other than IE the start and end date come through as:
Mon, 10 Jan 2011 00:00:00 GMT
When IE posts the date, it comes through as
Mon, 10 Jan 2011 00:00:00 UTC
ASP.NET MVC 2 will then fail to automatically bind this to the action method parameter. Is there a reason why this is happening?
The code that posts to the server is as follows:
data: function (start, end, callback) {
$.post('/tracker/GetTrackerEvents', { start: start.toUTCString(), end: end.toUTCString() }, function (result) { callback(result); });
},

i have a simple model [Code]....
when i render a view to show the data inside the model, i also need to write some javascript
how to get the ID value in the script from the View?
I've seen/read plenty advocating "unobtrusive" JavaScript contained in separate files. I'm preparing to combine all my JavaScript from three partial views into a single file that I will then reference somewhere in my master.
My question is: is there any type of JavaScript that should remain behind in the html? One example that seems to me may present a problem would be something like:
<script type="text/javascript">
$(document).ready(function () {
$('#newQuoteLink').click(function () {[code]...
Am I correct in assuming this script would not work if loaded from a separate file?I mostly wanted to check if there were any caveats or other considerations prior to combining everything into this lone, separate file.
Just found out this problem. Upgraded by site to jQuery 1.5.1. I had some cascading dropdowns populating via some very simple code like this:
[Code]....
This code no longer runs with jQuery 1.5.1 AND unobtrusive validation active. Fails also with jquery 1.5.0. Works fine with jquery 1.4.4.
Why is it that client validation is getting triggered saying that my Default Theme field is required even if I didn't specify a [Required] attribute in my model?
