View 1 RepliesI'm using a text book to teach myself ASP.NET 3.5. I'm using Visual Web Developer 2008 express to create my pages. At this point in my text, the author has me drag a DropDownList control to the Web page and then tells me to go to the Properies window and look at the Items property. I don't see an Items property. I've doublechecked that I'm on my DropDownList control, but I see no Items property. Is this a bug in VWD, an error in the book, or just plain old User error?
I'd be willing to hard-code the property in the source window, but I don't know the syntax. I tried
items="Vanilla, Chocolate" but nothing appears in the list when I view the screen.

View 1 RepliesI have a main "index" view that has a drop down and a submit button. When a selection is made (CampaignId) and a submit button is pressed a list of items is displayed and filtered based on the selection from the drop down list.
I've added a partial view (on the right rail) of my site that lists a bunch of campaigns. when a link is pressed in that partial view a (CampaignId) is passed to my page and the same thing happends as if you would make a selection from the drop down. The issue is that the dropdown "Campaign Name" should be selected based on the selection from the partial view.

View 2 Replies I have a class Person that represents a person in my database. This class has a CategoryId property (int) and a Category property (type Category).
Category is a class that represents a category in my database. csharp Code:
public class Person{ public int Id {get; set;} public string Firstname {get; set;} public string Lastname {get; set;} public int CategoryId {get; set;} public Category Category {get; set;}} public class Category{ public int Id {get; set;} public string CategoryName {get; set;}}
[code]....
I am displaying a list of these Persons in a GridView, and I would like to display the name of the Category (the CategoryName property to be precise). So I define this markup;
xml Code:
<asp:GridView runat="server" ID="personsGrid" AutoGenerateSelectButton="True" AutoGenerateColumns="False" DataKeyNames="Id"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" /> <asp:BoundField
Usually I would solve this problem by one of two ways:Override the ToString method of the Category class and return the name.
Add a readonly 'CategoryName' property to the Person class, where I return 'this.Category.CategoryName' (and then bind the column to this property instead).
In this case however, I am using the Entity Framework, and the Person and Category classes are automatically generated by the database model. I suppose I could edit the generated code manually, but I don't like that, since any change in the model will cause VS to re-generate the code and my changes would be lost. So these two methods are not going to work...
The simple question remains: how do I make the Category column show the CategoryName property of the object it represents, rather than just the type name?In a DropdownList for example (which I am already using for the user to select a category when creating a person), I can set the DataTextField (to "CategoryName") and DataValueField (to "Id") properties and it displays the right name and uses the right value (the Id). I can't find anything similar for a BoundField though... Am I overlooking something obvious?
Another solution would be if I could tell the Entity Framework model to add another property to my Person class which returns the CategoryName of the Category. I can't find any way to do that though (I am a compleet noob in EF),
I have been playing a bit with ASP.NET MVC 2 using VWD 2010.After a bit of struggling with profiles(thank you MS for putting 2 web.config files in the solution...) I decided that after all I like this technology. I always thought that dotNET would be great for server side stuff and I've been proven right.Anyhow, I'm gonna start a real project now and I want to do something weird(yes, I know, I shouldn't be wanting to do weird things, but it's just beyond me :-) ): say I have a company website with roles and a forum.When I click on the nickname of a user, I want to bring his/her profile up - just like you would be doing with any decent forum out there. Well, my final idea is a tad more interesting in this regard, but let's stick it at that: click and see profile page.Problem is, I want this profile to be different for company employees and users.
I want some general informations such as first and last name, date of birth, photo, etc and then for instance I do not want to show the address property for company users. Yes I know I might want to put the company address there or leave it at all blank and I would rather not display it at all.From what I gather about profiles, this is possible only using views and checking for the roles, doing something like:
if User.Role == Company
{
// Stuff here

I'm trying to keep track of employees in my database. I have two tables, Employees and Departments. The Employees table contains a foreign key relationship with Departments through a column named DepartmentID.
Here's my entity:
[code]....
I have a page that contains a form to add an employee. I'm passing the entity to my view page, and calling <%: Html.EditorForModel() %>
The problem is that the view creates a textbox for the DepartmentID.
How can I force the view to display a dropdown for DepartmentID that contains all the Departments in my database as the dropdown's list items? Is there a way to do this by just adding a metadata attribute to the property in my entity?

Is there a way that I can extend asp.net to accept the markup
<c:MyControl runat="server" MyList="1,2,6,7,22" />
Where MyList is a List<int> or List<string> or even List<someEnum>?
So I want asp.net to parse automatically all lists (that can be parsed) generically.
I know I could take the way around it and make MyList a string, then parse that into a list, but then I just end up with more properties than I want tbh.

I have a check-box-List which I bind to a master dataTable(DTA)... I have another dataTable (DTB) which has the values that needs to checked in the check-box-List... So I loop through all items in the check-box-list to see if it exists in the DTB and set checked = true for those items that exists. Now I want to show the checked items first in the Check-box-list box and the unchecked items below that. Is there any way I can do it... A similar solution for List-Box could also be helpful. A Javascript hint is welcome too.
View 1 RepliesI am using javascript to validate user input on my aspx page. I am easily able to validate textboxes and dropdown list for differenet scenarios.
Now, on one of my dropdown lists (for country), I need to check if it is an allowed country or not for a particular service. I have stored the valid country list in a static property. Is there a way to validate my dropdownlist selected value against that static property?
function validateService(source, args)
{
var country = document.getElementById('<%= ddDestCountry.ClientID %>');
var service = document.getElementById('<%= ddService.ClientID %>');
// Get allowed country list from my static class
var countryList = document.getElementById('<%= StaticProperties.EUCountryList %>');
if (service.value == "P")
{
// I want to do something like this
if (!countrylist.Contains(country.value))
{
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
return;
}
Update(Additional Information): The static property is read-only so it cannot be tampered with from the page.
