MVC Validation Pattern Question, Especially for Variable Length Lists and Conditional Validation


I've spent a lot of time exploring the various patterns of MVC validation. In particular, I am interesting in learning best-practice for validating a view which posts an enumerable collection back to the controller. One approach that is appealing involves posting the form via Ajax to check validation (http://jvance.com/blog/2010/02/20/MakingAnAjaxFormWithJQueryInASPdotNETMVC.xhtml). Obviously, the negative is that this is not true client-side validation since there is a "hidden" server round-trip, but the effect is comparable, and obviously client-side validation alone will never stand--server-side always needs to be done as well.

The CodePlex repository for this demo: http://mvcajaxvalidation.codeplex.com/SourceControl/list/changesets

The main reason I started heading this route is because in the course of writing lots of custom data annotation model validators (think "RequiredIf" or "RequiredWhenContains") it became very evident that the wiring to the client-side gets complicated. I was mostly able to pull it off using the custom validators' GetClientValidationRules() plus jQuery validator extensions (.addMethod('requiredif'...), ho

Local variable scoping in C#

In my previous post, Compiler-generated scopes for local variable declarations, I briefly touched on the issue of multiple meanings applied to the same name. In this post, I'll aim to flush out the compiler's rules with regards to binding names in their local scopes.

Compiler-generated scopes for local variable declarations

I was tasked with understanding and fixing a bug on error reporting with foreach iteration variables the other day, and it got me thinking about local variable scoping rules in C# in general. First, the bug.

Server side validation of Fileupload control not working



I've tried this method in my code behind to try and validate that the Fileupload control has a file or not. I get the error message the the event "Server Validate" cannot be found. Can anyone tell why? Thanks.

Public Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate

' Get file name

        Dim uploadAvatar As FileUpload = DirectCast(AdvertisementForm.FindControl("uploadAvatar"), FileUpload)

        Dim UploadFileName As String = uploadAvatar.PostedFile.FileName

        If UploadFileName = "" Then
            ' There is no file selected
            args.IsValid = False
            Dim Extension As String = UploadFileName.Substring(UploadFileName.L

Retrieving a variable from a previous page



I'm looking to have a search page where a user will select an item from a listview, then then taken to another page that wil display data based on their original selection.

A user will type in a string and be presented with a list of usernames that are like that string, when they select a user name who's profile they would like to view I would like the page that they're taken to, to be that users profile.

How would I transfer the variable from the search page to the profile page, and when I work on the profile page, how can I access that variable?


Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

How to take value of bound field of grid in a variable or in a textbox.


How to take value of bound field of grid in a variable or in a textbox.

 I m using this code in .aspx page for grid.

<asp:GridView ID="Grd_Mprocess" runat="server" AutoGenerateColumns="False"

                      Width="100%" AllowPaging="True"


                      AllowSorting="True" PageSize="5"  >

Hidden variable has no value


I know I have a valid solution, but the js is telling me that the value in the hdnRecordSaved variable has no value!
Even when I specify in my function the following, it still tells me it has no value:
var myTextField = document.getElementById('hdnRecordSaved');

When I put the full value of the variable in (ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value), I get the correct contents back ("1"), which I set in my code behind. However, I would prefer to just put the short name in since the masterpages may change, etc. Unfortunately, I know I can get around this with VS2010, but we are using VS2008.

What am I doing wrong with the js naming conventions that can't give me the contents? Here is my below js.

<asp:Panel ID="pnlMapFields" runat="server" ScrollBars="Both" Height="430px">

<telerik:RadTreeView ID="RadTreeView1" runat="server" DataTextField="Description"

DataFieldParentID="MapFieldparentID" DataF

VS 2010 HTML validation "in CSS" option - where the hell is it?


In VS 2008 there is a very useful feature of background HTML validation - it checks if CSS class name is valid i.e. it exists in one of the linked css files. But VS 2010 Express does not do that any more. And the relevant setting in Options->Text Editor->HTML->Validation->in CSS is not there. Ok, maybe they made it paid for option? VS 2010 Professional? Not there. Or maybe VS 2010 Ultimate? Not a trace.

1. am I blind?

2. they decided it is too convenient to use and removed it?

3. they will "introduce" it in SP1?

What is going on? That one thing made me move back to VS 2008 web developer.


How to retrieve data from SqlDataSource and pass to a variable?


Hi there,

I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:

    <asp:SqlDataSource ID="sdsFormOrderDetails" runat="server" 
ConnectionString="<%$ ConnectionStrings:ForexDB %>"
ProviderName="<%$ ConnectionStrings:ForexDB.ProviderName %>"
SelectCommand="usp_GetOrderDetails" SelectCommandType="StoredProcedure"
UpdateCommand="usp_UpdateOrder" UpdateCommandType="StoredProcedure"
<asp:ControlParameter Name="orderId" ControlID="grdOrders" PropertyName="SelectedDataKey.Value" />
<asp:ControlParameter Name="orderId" ControlID="frmOrderDetails" PropertyName="SelectedValue" />

User validation Issue in xlsx file



I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names.

So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".

But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.


set messageTemplateResourceName from resource file in Validation appication block.



  I am using Validation application block in my project and want to set validation message from resource file, but not able to do that. I tried giving the path of resource file in messageTemplateResourceType and name of resource in messageTemplateResourceName. But it did not help as I only receive the message if I have set something in messageTemplate even after setting the resource file.

Here is my code:

<validator lowerBound="1" lowerBoundType="Inclusive" upperBound="250"
              upperBoundType="Inclusive" negated="false" messageTemplate=""
              messageTemplateResourceType="Asurion.jCare.Common.Resources.UIResources.PerilTypeAndDetailsSection, Asurion.jCare.Common.Resources, Version=, Culture=neutral, PublicKeyToken=null"
              tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.Enterpris

Localize framework message from xml validation error


I need to validate an XML through XSD. I am using XMLReader (with XmlReaderSettings and

Any idea on how to perform this?
