MVC :: Validating Custom Types And Html.EditorFor() Templates?
Sep 2, 2010
I'm finding my self with the problem that if I do not show the Template for a "complex" object I have in the main view object I still get the errors in the summary. How do i get around this?
I've got a model with say:
->Persons (has its own editor template)
->Pets(has its own editor template)
In the create view I show each one depending if they are not null. But when I try to validate HouseType and say I have Persons not null and pets is null. I get errors of validation for pets.
How do I get around this?

I've been trying to something with the templating system in MVC2, but what I thought should be simple has not been successful. So now I question if it's possible or if I'm missing anything obvious. The scenario:
I have a base template as a strongly typed view that is set up in the ViewsSharedEditorTemplates folder...call it CommonItem.ascx. It wants a model item of type MyItemType.
I have a template that is a wrapper around the previous template, is also strongly typed of type MyItemType, residing in the same folder. Call this one CommonItemWrapper.ascx.The contents of CommonItemWrapper.ascx includes divs before/after a declaration Html.EditorForModel("CommonItem").
My expectation would be that the inner template (CommonItem) would be displayed within the outer template. Unfortunately the inner template never gets evaluated.
Am I missing something? Am I mistaken in thinking that templates can be nested in this manner? If so, is there another means to accomplish this?

If I wanted to create a custom HTML helper and take advantage of the new in-built templating feature, how would I do that? It appears the templating features are internal?

I added a RequiredFieldValidator to my InsertItemTemplate, and it seems to be working fine. The problem I am having, however, is that now I cannot do anything else in the ListView (like edit or delete items) UNLESS the required field has a value. Is there some way I can manually do the validation when the user clicks the 'Insert' button on the InsertItemTemplate, or some other little trick I can perform so the user doesn't have to first type in a value just to delete something else in the list?

I would like to exclude one of model's property from the Html.EditorFor. I tried [HiddenInput(DisplayValue=false)] but it renders the property as an hidden input. This could potentially be a security problem. How can we completely exclude a field from Html.EditorFor?

I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?

i am working on an asp.net mvc 2 web app and inside my model i would like to include a field named "" that has the values "Male" and "Female". I would like to use custom templates and Data Annotations in order to take advantage of model metadata. Specifically, i would like to create one DisplayTemplate (displaying the value) and one EditorTemplate (displaying a dropdown list) for the "Sex" type field.

I have a comment form inside the blog posts. in the form, if the user is authenticated, I will assign the values of the user into textboxes. that part is as follows;
[Code]....
But when I add HTML.TextBox instead of HTML.TextBoxFor, I am not getting validation if the user erase the fileds. Also, this form is inside the indext page and it is related to another action as follows;
[Code]....
so I cannot assign ModelState.AddModelError from controller.
What should I do here.

I m Using a GridView: Columns: "Ser_type" tells what type of data is it i.e. VC for Varchar, NU for Numeric, DT for DateTime etc, for the time being i m using datavalidation controlls at design time. this is not a good approach. I just wan to do is that, DataValidationControlls should be created at RunTime and TextBox should validate data at runtime only. i.e. if Data required in the TextBox is of Type VC then it should validate only at runtime, if DT then validate DateTime only at Runtime similarly for all dataType:

I have radiobuttons within a datalist. The page where they appear is within a master page. The method I had in mind of achieving the validation is with a custom validator and the following sub:

The problem with this code is form1 is not declared. As it is passed in from the master page.
I also have tried another method as follows:

Using C#, ODP.NET and ASP.NET Web Services:
ClassA is a custom class generated from a "type" in oracle database.
ClassB is a custom class generated from a "table of type ClassA" in Oracle database.
The exposed service includes a login procedure which gets a username as input parameter and returns object B. Debugging the login procedure I can see that the data is retrieved from the database but not printed in the wsdl..
[Code]....
My ClassB definition is as follows:
[XmlInclude(typeof(ClassB))]
public class ClassB : INullable, IOracleCustomType, IXmlSerializable
...
similar definition holds for ClassA as well. the generated wsdl is :
<? xml version="1.0" encoding="utf-8" ?>
<ClassB xmlns="http://tempuri/org" />
and no data printed out. What may be the problem?

I'll use Customer and Addresses as an example rather than explain my real objects. Say I have a repeater bound to a collection of Customers and one of the properties of Customer is an array of addresses. How do I bind to the addresses property? I don't even need to display this information I just want to use it in the Repeaters ItemDataBound event. So I tried to bind a hiddenField to the addresses property but all I get for every customer in the hiddenfields value is an empty array of addresses.

In my ASP.NET MVC 2 web application, I allow users to create custom input fields of different data types to extend our basic input form. While tricky, building the input form from a collection of custom fields is straight-forward enough.However, I'm now to the point where I want to handle the posting of this form and I'm not certain what the best way to handle this would be. Normally, we'd use strongly-typed input models that get bound from the various statically-typed inputs available on the form. However, I'm at a loss for how to do this with a variable number of input fields that represent different data types.A representative input form might look something like:
My date field: [ date time input
control ]
My text field: [ text input
field ]
My file field: [ file upload
control ]
My number field: [ numerical input control ]
My text field 2: [text input field ]
etc...
Ideas I've thought about are:Sending everything as strings (except for the file inputs, which would need to be handled specially).Using a model with an "object" property and attempting to bind to that (if this is even possible).Sending a json request to my controller with the data encoded properly and attempting to parse that.Manually processing the form collection in my controller post action - certainly an option, but I'd love to avoid this.Has anyone tackled an issue like this before? If so, how did you solve it?Update:My "base" form is handled on another input area all together, so a solution doesn't need to account for any sort of inheritence magic for this. I'm just interested in handling the custom fields on this interface, not my "base" ones.Update 2:Thank you to ARM and smartcaveman; both of you provided good guidance for how this could be done. I will update this question with my final solution once its been implemented.

I have a custom user control with some input fields and a submit button. I need to validate the fields using the jquery validation plugin when the submit button is clicked. (The function of the submit button is to create another custom control which displays the data entered in the above mentioned control)
Bt as far as I knw, validation plugin works only with form validation ryt? And my custom control does not contain a form tag as I am using master pages. The custom control is present in one of the content pages and the master page already contains a form tag with a runat=server attribute. And I guess one page can contain only a single form tag with runat=server attrib ryt?
So how do I get it to work?
