I am trying to convert some repetitive html into a user control. Here is the HTML :
[Code]....
And here is where I am slotting it in to my original HTML :
[Code]....
I need to do this dynamically, is there any way around this?
I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

View 1 RepliesI'm using ASP.NET MVC 2 Beta. I made a sample code to describe my question.
In the /Controller/HomeController.cs
using System;
using System.Web.Mvc;
namespace MvcApplication9.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
public ActionResult Index()
{
return View();
}
}
}
I have created a custom html helper as follow:
[Code]....
In my View, I am using it like this:
[Code]....
However, for some reason nothing gets rendered!
I saw this implemented somewhere but basically below I'm using the textbox HTMLHelper to draw a textbox with the id myID and default text 'text_goes_here'. I want to also add a class to thiis helper, i saw somewhere it implemented with new {@class =''} as a third parameter creating an object but im not sure exactly how its wrote
<%= Html.TextBox("myID", "text_goes_here") %>
I would like to know what the pros and cons are of creating an extension method v a partial view. From my understanding, htmlHelper extension methods are better as they enable one to unit test the view.
e.g. Assert.AreEqual(Html.Price(), "<td><tr><td>Price</td><td>4.50</td></tr>");
where the Price() method contains the presentation logic.
Since both the extension method and partial view are reusable, what then is the point / benefit of a partial view?
My project is developed in asp.net 2.0 and uses the System.Web.Extensions.dll in it. The project was working fine earlier. One of my collegue installed the Ajax Minifier in the system and after that an error is triggerred from my application: Type 'System.Web.UI.ScriptManager' does not have a public property named 'LoadScriptsBeforeUI'.I have modified the web.config and tried several options. But, didn't solved the issue.
View 2 RepliesI am using a web method to submit my form data , having Oracle DataBase. And in my local development machine every thing is fine.I am successfully able to submit my form data asynchronously through a web method. But the same project when deployed to test server then while submiting form date there an error occurs as stated above. One field in the table is of DataTime type, and i am inserting server's date into that field, all other fields are of type varchar2 or int. I googled about that but it seems that no one has got such error.
View 16 RepliesI'm using a html helper that i got from here: [URL] here is my modified version (using SelectListItem):
public static string CheckBoxList(this HtmlHelper htmlHelper, string name, List<SelectListItem> listInfo)
{
return htmlHelper.CheckBoxList(name, listInfo, ((IDictionary<string, object>)null));
}
public static string CheckBoxList(this HtmlHelper htmlHelper, string name, List<SelectListItem> listInfo, object htmlAttributes)
{
return htmlHelper.CheckBoxList(name, listInfo, ((IDictionary<string, object>)new RouteValueDictionary(htmlAttributes)));

public static string CheckBoxList(this HtmlHelper htmlHelper, string name, List<SelectListItem> listInfo, IDictionary<string, object> htmlAttributes)
{
if (String.IsNullOrEmpty(name))
throw new ArgumentException("The argument must have a value", "name");
if (listInfo == null)
throw new ArgumentNullException("listInfo");
if (listInfo.Count < 1)
throw new ArgumentException("The list must contain at least one value", "listInfo");

I can't seem to figure out why this always throws an error: CS1928: 'System.Web.Mvc.HtmlHelper<DataLayer.BlogPost>' does not contain a definition for 'CheckBoxList' and the best extension method overload 'HtmlHelpers.HtmlHelpers.CheckBoxList(System.Web.Mvc.HtmlHelper, string, System.Collections.Generic.List<System.Web.Mvc.SelectListItem>)' has some invalid arguments
i have defined a dropdown list in the controller
[Code]....
then i can show this dropdownlist in my "about" view <%=Html.DropDownList("a") %>.
BUT, now i want to define this dropdown list at my back end. what i want to do is to create a new "Helper".cs file in my project, and create a function within it. so every time if i want to show this dropdown list, i can just simply call this function instead of Add new SelectListItems one by one. is there anyone tell me how to do it?? and is it a good way to create a dropdownlist at the back end?

I have a project that it had been developed under MVC1 and after aa few months ago I upgraded it in MVC2.
Everything was well, uppon the day I needed to format my computer.
And what can goes wrong with a format? I don't know
I have installed the MVC2, I build the project, no error displayed, but from the time I've uploaded the project in the production server
I am getting this error.
Method not found: 'System.Web.Mvc.MvcHtmlString System.Web.Mvc.Html.LinkExtensions.RouteLink(System.Web.Mvc.HtmlHelper, System.String, System.Object)'.
I can't understand what caused the problem.
Certainly I assumed that is have to do with MVC1 and I referenced it, but with no luck
again.
Theese are the methods that the problem is came from

I had to format my hard disk and reinstall the Visual Studio 2005 Enterprise and SQL 2005 Standardprograms.
While my program worked perfectly before and still works ok on my second computer, I get the following error message on the formated computer:
Parser Error Message: Type 'System.Web.UI.WebControls.Parameter' does not have a public property named 'DbType'.
Source Error:
Line 82: <asp:Parameter Name="Olho" Type="String" />

In this case I use a datasource control for a datalist and the parameter list is being built ba the system.
The DBType is created for the smalldatetime feild
how do I add the property named 'DbType'.
We have a Page Method on a web page using ASP .Net. We tried to put in a trace statement using both System.Diagnostics and System.Diagnostics.Debug. In Visual Studio 2008, the break point is not even hit for the line, but other break points on other lines are hit.There is no output from either method that we can see.
There is also a Global.asax error catcher that works fine in other cases, but in the Page Method is not being catched.why a Page Method and System.Diagnostics do not play well together?

View 2 RepliesI know S#arp architecture is built for ASP.NET MVC. But I'm wondering if it can be used in classic ASP.NET (WebForms) or even desktop applications like WinForms or WPF.
View 3 RepliesI'd like to be able to determine what class will be called given an URL. For instance, I have a page /First.aspx that has a hyperlink to /Second.aspx In the code behind for First.aspx.cs, I'd like to be able to determine what class will execute if someone clicks on the hyperlink that points to /Second.aspx.
EDIT: One of the reponders asked me to outline the problem I'm trying to address. Here it is: The codebase I inherited has a subclass the System.Web.UI.Page that has a public Authorized method that returns a boolean. The Authorized method checks the parameters passed via the query string against the authenticated user, and determines whether that user should be allowed to call that page with the given parameters.
Elsewhere in the site I have hyperlinks that reference those protected pages. In some instances those links are displayed to users who are not authorized to navigate to that page. They can click the link, however they get an error. In other instances, prior developers when through the trouble of inserting logic that hides the hyperlink for those unauthorized users, but the authorization logic is duplicated (In the page itself, and in the linking page). What I would like to do is create a subclass of the hyperlink class, and have the subclass inspect the NavigateUrl, determine the destination page class, and call the Authorized method of that class to determine if the user is authorized to call that page. If the user is not authorize, the link will automatically hide itself.

I'm trying to follow the demo from this link to add a jqGrid to an MVC app.
I have a table named Companies that I'm trying to display in a grid. A Company simply contains an ID and a Name.
I'm running into an error in my controller function:
public JsonResult DynamicGridData(string sortIndex, string sortOrder, int page, int rows)
{
int pageIndex = Convert.ToInt32(page) - 1;
int pageSize = rows;
var companies = companiesRepository.Companies.OrderBy(sortIndex + " " + sortOrder).Skip(pageIndex * pageSize).Take(pageSize);
//Error here

}
I'm getting an error on the line that is calling OrderBy():
The type arguments for method 'System.Linq.Enumerable.OrderBy(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly.
I really have no idea what the error means, and I haven't been able to find an explanation. I'm not sure what is causing this error on a simple OrderBy function.

Has anybody else had an issue with the sender address not being used as the return-path/bounce address when using system.net.mail to send email with a different address for the return-path/sender and the from address and using the SpecifiedPickupDirectory delivery method? This issue is particularly important when you need to send mail from a "user" address, but want bounce backs to come to a different address so they can be processed. Using the code below, I think you can reproduce the issue.
Imports System.Net.Mail
Partial Class emailtest
Inherits System.Web.UI.Page
Protected Sub test_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles test.Click
' Build Message
Dim mail As New MailMessage
mail.To.Add("user@gmail.com")
mail.From = New MailAddress("from@domain.com")
mail.Sender = New MailAddress("sender@domain.com")
mail.Subject = "Test Subject"
mail.Body = "Test Body"
' Drop in Pickup Directory
Dim smtpPK As New SmtpClient
smtpPK.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory
smtpPK.PickupDirectoryLocation = "C: emp"
smtpPK.Send(mail)
' Send Message Directly
Dim smtp As New SmtpClient("mail.domain.com")
smtp.Send(mail)
End Sub
End Class
