C# - Make An Entry Field Optional?

Feb 2, 2010

I have made an entry field required somehow but I'm not sure how. When editing a tag, the tag owner entry field should be able to be empty.I have set "allow nulls" in the database table:Does anyone know how I can fix it? To be clear, I want the above form to be submitted without requiring a value for tag_owner.

C# - Handle Foreign Key For Optional Field?

Mar 23, 2010

What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution?

Make A Section Optional With The Mvc Razor ViewEngine?

Feb 4, 2011

I have a Page.cshtml similar to the following (that does not work):

@{
Layout = "../Shared/Layouts/_Layout.cshtml";
var mycollection = (ViewBag.TheCollection as IQueryable<MyCollectionType>);
}
<h2>@ViewBag.Title</h2>

content here

@if (mycollection != null && mycollection.Count() > 0)
{
@section ContentRight
{
<h2>
Stuff
</h2>
<ul class="stuff">
@foreach (MyCollectionType item in mycollection )
{
<li class="stuff-item">@item.Name</li>
}
</ul>
}
}

As I said, this does not work. I want to not define the section if there's nothing in the collection. Is there any way to have something like this work? If not, what are my other options? I'm very new to this Razor ViewEngine. Edit In my layout i have:

@if(IsSectionDefined("ContentRight"))
{
<div class="right">
RenderSection("ContentRight")
</div>
}

what i don't want is the div to output when the section is empty.

How To Make Validation Optional For A Complex Type In Mvc

Feb 23, 2011

I want to display an editor for a type User. User contains a field Address of type Address. I made an editor template for the type Address so that it is reusable.

I don't want the field Address to be required for creating a user. But some fields are required for Address, for example country, state etc.

I want to validate Address if I receive any data for it, if I don't receive anything, then I don't want to return any validation error to the UI for Address. I would return only validation errors for User then.

State Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?

Mar 23, 2011

I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.

I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

How To Make A Text Field

Mar 1, 2010

I know that this is easy for those that know but alas this is not me ;)

I have a multi part form that is going to write to a dB.

As a point of reference I can offer [URL](i.e., the quote process) as a model for my project.

I need to write a record on the first page and then use the auto number generated from this to populate the child records with the parent's key field.

What I was hoping to do is write the record and then send the data from the dB to the second form. Iwill then need to repeat this process for the children of the child

I am only moderately familiar with ASP.net

one thing to add is that i am not forcing the user to create an account in order to maje the initial inquiry, only if they wish to reaccess theinformation at a later date.

Conditionally Make A DetailsView Field Read - Only?

Jan 26, 2011

Say I have a DetailsView with a bunch of fields, and I want only certain kinds of users to edit a few of them. They're too few to split them into another DetailsView, so what I'm thinking is to find some way to only allow a user to edit them based on some code-behind logic, effectively making them read-only at will.

I feel it's important to mention that the fields are both TemplateFields, not normal BoundFields with ReadOnly properties. For some reason the required functions don't jump at me from reading the documentation. Oh and I need eveyone to see their specific values, I just want to restrict edit access to them.

How To Make NHibernate Serialize A Given Property To A Binary Field

Sep 14, 2010

I have a simple ASP.NET MVC web application that uses NHibernate with FluentNHibernate's auto mapping feature for its data access. I have encountered a scenario in which I would like NHibernate to persist some classes as binary data.

public class User
{
// This field will be persisted
public virtual byte[] PortraitData { get; set; }
// This method will get me what I'm actually interested in
public virtual Image GetPortrait()
{
return SerializationHelper.Deserialize<Image>(PortraitData);
}
}

(I leave the implementation of the SerializationHelper class to the reader's imagination. It doesn't do anything complicated, just serializes and deserializes data into byte arrays and back.)

Forms Data Controls :: EditItem Template Of Gridview - Template Field With Dropdown List - How To Make Current Value Sel

Dec 4, 2010

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
