C# - How To Call A Javascript Method After Action Or From A View
Feb 12, 2010i just want to be able to call a javascritp subroutine on the client, after the server has done its thing (when an action completes or control goes to the view, i'd dont mind calling the js from the view either).
for some reason, even vs2010 doesn't let me put breakpoints in <% ... %> tagged areas between <script...> and </script> tagged areas. i for this reason can't figure out whats going on and how it's running things. here is what i've put in my view, and the javascritp should run, but it doesn't....
im just trying to call "RunOnceRoutines;" but it's not getting called!

Passing A JavaScript Variable To A Helper Method?
Feb 24, 2011I am using ASP.NET MVC 3 and the YUI library.I created my own helper method to redirect to an edit view by passing in the item's ID from the Model as such:
window.location = '@Url.RouteUrl(Url.NewsEdit(@Model.NewsId))';
Now I am busy populating my YUI data table and would like to call my helper method like above, not sure if it is possible because I get the item's ID by JavaScript like:
var formatActionLinks = function (oCell, oRecord, oColumn, oData) {
var newsId = oRecord.getData('NewsId');
oCell.innerHTML = '<a href="/News/Edit/' + newsId + '">Edit</a>';
};

public static string YuiResetFontsGridsStylesheet(this UrlHelper helper)
{
return helper.Content(yuiBuildPath + "reset-fonts-grids/reset-fonts-grids.css");
}
}
Here is my unit test:
[Test]
public void YuiResetFontsGridsStylesheet_should_return_stylesheet()
{
// Arrange
RequestContext requestContext = new RequestContext();
UrlHelper urlHelper = new UrlHelper(requestContext);
// Act
string actual = urlHelper.YuiResetFontsGridsStylesheet();
// Assert
string expected = yuiBuildPath + "reset-fonts-grids/reset-fonts-grids.css";
Assert.AreEqual(expected, actual);

How To Make A Custom Strongly Typed Html Helper Method
Dec 2, 2010Now I found out how to create custom html helpers
using System;
namespace MvcApplication.Helpers {
public class InputlHelper {
public static string Input(this HtmlHelper helper, string name, string text) {
return String.Format("<input name='{0}'>{1}</input>", name, text);
}
}
}
Now how to turn it into a strongly typed helper method InputFor Like it is in the framework?I don't need the Html.TextBoxFor method, I know it exists. I am just curious in how to implement this behavior myself and used this as a simple example.PS. I was looking in the mvc source code but couldn't find a trace of this mysterious TextBoxFor. I only found TextBox. Am I looking at the wrong code?

Javascript Refuses To Call ActiveX Method - Agrees To Call Another
Mar 4, 2010I have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.

Invoke Asynchronous Method Call From .NET?
Jul 20, 2010I'm currently working on a web site which involves a data upload process. The file is currently uploaded to the server method is called (in app_code) where ultimately a DTS package is called (via a web method) to load the data into a database and perform some validation on it.The client has specified that they don't want to have to wait for the DTS package to execute (execution time is less than 5 minutes) so it appears that I need to call the method asynchronously. The user will probably logout or close the browser window while this task is running so I believe I'm unable to run this on an asp.net thread.
