MVC :: ValidationAttribute.IsValid - ValidationContext Always Null?

Feb 17, 2010

I'm using ASP.NET MVC 2 RC 2 (verified, the DLL has been signed on Friday, 29. January 2010 7:14:16 pm).

I created a custom validation attribute, which is described here (blog post is in German, however the code is not).

The problem is: that all works fine in theory (and unit tests). But by executing it in "the real world", which means firing off a form post to the server, it doesn't work. The commited validationContext is always null.

Is that a known issue? I would call that a real bug because it makes it impossible to use that method. And by using the other one I don't have access on the given context.

MVC :: Validation Attribute Fails With Deeper Objects IsValid Parameter Is Null?

Apr 9, 2010

I have an CustomViewModel that is composed of three layers of objects.

The first one is to store and populate lists to be used in dropdowns.

The second one is to store additional propperties that I want.

And the third one is the model itself.

I create the view using View(new Layer(model))

And at the post i have ActionResult .... (Container container)

I made this architecture because i was having a lot of problems with model binder and enums...

So when i post to the form and the ModelBinder checks the validation attributes, the IsValid operation at the attribute X applied to the model class has its parameter value as null.

This behavior doesn't happen if I Just use the simple model to create and post the view.

What I have to do to get this work ?

I made a few changes to the AccountController to use it as sample here, here is the code:

[Code]....

Just change the register page to inherits from RegisterModelLayer.

When I post, the value parameter at the IsValid function at the PropertiesMustMatchAttribute class is null;

As a consequence i can't validate and get an null exception maybe.

MVC ModelState.IsValid Returning False?

May 21, 2010

I am working in an ASP.NET MVC Application. I have a view model as follows:

[code]....

From UI Perspective user can enter date as mmddyyyy. And when user enters in such format 01012001, my ModelState.IsValid code piece in controller returns false. When I did a quick watch in ModelState, I see an error for the propery "SampleDate", saying "The Value 01012001 is not valid for SampleDate".

In my modelbinder, during the OnModelUpdated event I tried to format the value 01012001 to 01/01/2001 and assigned it back to SampleInterestViewModel.SampleDate thinking that ModelState.IsValid might return true without that error. But still ModelState.IsValid is false and I when I looked in to the ModelState dictionary, this particular property still has that errors in its collection.

Lastly I tried to format 01012001 and update the value 01/01/2001 directly to the Property SampleDate in the ModelState dictionary. But still ModelState.IsValid is false showing the same error for the SampleDate property. Can't figure out why ModelState.IsValid works and how and when it gets set to false.

If the User enter 01012001 in the UI, I still need to format it in the modelbinder to 01/01/2001 and make sure that ModelState.IsValid it true so that the rest of my controller code can work as expected. In the UI I am doing an AjaxSubmit to post the sampleDate value.

Is it necessary to do a ModelState.IsValid check at the top of every action? It seems that it is since the default model binder could make it invalid depending on the action parameters.

C# - Page.IsValid Cannot Be Called Before Validation Has Taken Place?

Mar 18, 2011

I am using a wizard control in which I have a next button that has causes validation = true. I also have a checkbox that when changed, in the event handler, I set causes validation = false for the next button. When that button is clicked - I get the following:

Page.IsValid cannot be called before validation has taken place. It should be queried in the event handler for a control that has CausesValidation.

Here is the code:

protected void chk_CheckChanged(object sender, EventArgs e)
{
CheckBox chk = (CheckBox)sender;
ImageButton ibtnStepNext = (ImageButton)(this.WizardSummaryTemplate.CustomNavigationTemplateContainer.FindControl("StepNextButton"));
ibtnStepNext.CausesValidation = (!chk.Checked);
}

What would be the recommended solution to disabling validation for the next button so I don't see this error?

C# - PrinterSettings.IsValid Always Returning False On A Windows 2008 Server With IIS 7

May 21, 2010

In our code, we have to give the users a list of printers to choose from. The user then chooses a printer and it is checked to verify it is valid before printing. On a windows 2003 server with IIS 6, this works fine. On a windows 2008 server with IIS 7, it fails each time impersonate is set to true.

PrinterSettings printerSetting = new PrinterSettings();
printerSetting.PrinterName = ddlPrinterName.SelectedItem.Text;
if (!printerSetting.IsValid)
{
lblMsg.Text = "Server Printer is not valid.";
}
else
{
lblMsg.Text = "Success";
}

Each time this code is run, the "Server Printer is not valid" displays, only if impersonate is set to true. If impersonate is set to false, the success message is displayed. The impersonation user has full rights to the printer. Is there a way to catch the actual reason the printer is not valid? Is there some other 2008 setting I should check? update I found that IsValid fails when the IIS7 application pools has "Enable 32-bit applications" is checked. This must be checked b/c we are using a 3rd party tool to print with, and it is a 32-bit application. It is not currently part of this test, so right now it is not causing this error.

AJAX :: MaskedEditValidator Page.IsValid Returns False When Using "en-UK" Culture?

Feb 4, 2011

[Code]....

The following setup seems to work fine on the client side, however when I post back and check Page.IsValid, the value is false. I also looked at mevDate.IsValid and it's false. It seems that setting the CultulreName on the MaskedEditExtender is sufficient to get the MaskedEditValidator to emit the correct JavaScript, but on the server side of things it doesn't work. When I flip CultureName to "en-US" everything works as expected.

Forms Data Controls :: Displaying A Null Or Empty Cell For A Null Datetime Database Value In Gridview?

Dec 6, 2010

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?

I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

SQL Server :: Inserting Null Value Into Foreign Key Table With Allow Null Enabled?

Oct 2, 2010

I have 2 table Table A, Table B.

Table A - Parent Table

ID - Uniqueidentifier not null(PK)

Table B -Child Table

ID - uniqueidentifier null(FK, TableA)

I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.

The statement has been terminated.

The insert statement in asp.net is like so:

sqlcommand.parameter.add(New Sqlparameter("ID", Nothing))

I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.

Web Forms :: Session Variable Is Null When It Shouldn´t Be Null?

Mar 18, 2010

I have a problem with a SessionVariable. I will explain what is happening:

1. From the default.aspx I send Session["LoginByAdmin"] = "Dummy"; and then redirect to this page where I have the code below. So the Page_Load sees that this Session["LoginByAdmin"] != null and enter this page. This works fine !

2. In the Page_Load, I later fill a ListBox1 with foldernames.

3. With Button1_Click1, I will now delete the choosen Folder in the ListBox1 wich works fine the first time and the ListBox updates the new existing folders in the ListBox. (I have wrapped this inside an updatepanel)

The problems comes now when I try to delete a choosen folder in the ListBox1 the second time in a row. When I select a Folder in the ListBox1 and now Press Button1, I will be redirected to "Default.aspx". This meens that this code is running: (That meens that Session["LoginByAdmin"] == null and I have not set this to null anywhere. This is my big question how this variable can be = null here?

if (Session["LoginByAdmin"] == null)
Response.Redirect("Default.aspx");
break;

Null Value On .net DB Query

Jul 30, 2010

I've been working on building a back end on an access database that allows users to search records using a web search box. I've been able to successfully set up simple search query's but have run into trouble where multiple criteria with "AND" statements (OR statements would return too much to be useful). My problem is this, when all five text boxes are filled out the query returns records no problem, but if even one is left blank i get nothing what so ever. Is there any thing I can do in either SQL or VB to either ignore null values entirely or convert them to wildcard values?
