Can I call Ajax.BeginFrom from a custom helper method ?
AjaxHelper is not available in a custom helper method, so I tried to pass the "Ajax" available in ViewPage to Helper method while calling it, but then in method, BeginForm is not available on that passed "Ajax" parameter.
I'm trying to write a controller method that returns an ActionResult.
In this method, i would like to:
1. call an HTML helper method
2. Capture and store the HTML helper's rendered HTML in a string
3. Return the method with the rendered HTML wrapped as a JSON
How do i call the Html Helper method from my controller method? Simply using the static class HtmlHelper does not work.
i have this code in a ViewUserControl, everything in between the foreach i want to pull out and call from a helper method...

I am using ASP.NET MVC 3 and NUnit. I am trying to write a unit to test one of my helper methods. Here it is:
public static class UrlHelperAssetExtensions
{
private static readonly string yuiBuildPath = "http://yui.yahooapis.com/2.8.2r1/build/";
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);
}....................................
Now 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?
is it possible to call a custom method or class before accessing webmethod from pageMethods ?
View 2 RepliesI'm sure I'm going about this wrong but I'm trying to write a simple javascript method that will set a hidden type value upon a link click. I'm using the Html.BeginForm() helper that contains two links similar to:
@Html.ActionLink("Delete Review Only", "Delete", new { id = Model.ReviewId }, new { onclick = "SetDeleteType(1);" })
<script language="JavaScript" type="text/javascript">
function SetDeleteType(selectedtype) {
document.supportform.deleteType.value = selectedtype;
document.supportform.submit();
}
The supportform name obviously doesn't exists since I'm using BeginForm() and can't specify a form name. Is there a clever way of doing this without calling Forms(0) using jQuery or something or am I completely off?
I have created my own custom role provider class "SGI_RoleProvider" and configured properly.
Everything is working fine.
Suppose that I have added a public method say "SayHello()", then how can i call that. Because if i am using Roles then the method is not displayed. If i am forcefully using that Roles.SayHello() then compiler gives the error.
how can i call this. Because creating a new instance of SGI_RoleProvider is meaningless.
When I put a part of my form in a partial view, all form parts get unobstructive syntax except the form elements in the partial view. The only way I found how to "apply" the unobstructive syntax, is by starting another form inside the partial view.
@using (Ajax.BeginForm("SubmitHandler", new DefaultAjaxOptions()))
{
@Html.EditorFor(m => m.Name)
@Html.Partial("MyPartialView", Model)
}
PartialView:
@Html.TextBoxFor(m => m.SomeContent)
<input class="text-box single-line" data-val="true" data-val-required="This field is required." id="Name" name="Name" type="text" value="">
<input id="SomeContent" name="SomeContent" type="text" value="0">
So only the input element from the View has the unobstructive syntax and the partial view hasn't... Is there a way to apply unobstructive syntax inside a partial view, wich doesn't require you to begin a new form?
$("#Name").on("blur", function() {
if (Name != "" && Name != null) {
var options = {
type: "POST",
url: "ApplyNow.aspx/CheckName",

I would like to create a static helper method that I can call from a view.
Is it possible for a helper method to have access to the current ViewContext without needing to explicitly pass the ViewContext to the method as a parameter?
Something like HttpContext.Current except for ViewContext.

View 3 RepliesThis thread is more about learning, actually I have a web service which just returns string. I have been calling this service from code behind and updating lable with the string received from the web service.
Now I want to call web service using JavaScript. As far as I know, I have to add <asp:ScriptManager..../>. Second I have to add [ScriptService] to the web service.
But I don't wat to add <asp:ScriptManager..../> and [ScriptService].
Is there any way to call web service using javascript without adding <asp:ScriptManager..../> and [ScriptService]
Also, I am kind of lost in SOAP, JSON. I am not getting where I actually use SOAP, JSON. Using <asp:ScripManager../> and [ScriptService], I actually didn't see use of SOAP, JSON.

In our application we have a scenario where we need to display a panel using modalpopupextender after performing an async call on the server. We were using the Show method for displaying the popup. It used to work fine without any async call. But when an async call was introduced during the request processing the popup is not getting displayed.
View 7 RepliesI am using VS 2008. I am using Ajax Autocomplete extender to populate a textbox. usually there is a webservice method which populates data into the autocompletion list... but in my case, the data is coming via an instance method...
At the time of doing the autocomplete, the autocomplete calls the method, the data is getting lost in the page postback..My situation is such that I cannot use a static method to get data from database, since there is already a public instance method.I am using the technique of calling GetAutocompletionList without using a WebService method.
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetAutoCompletionList(string prefixText, int count, string contextKey)
{
// want to use static viewstate here ..
I am trying to call a simple method in my code behind using Jquery with Ajax. But I get a 404 not found exception everytime. Unfortunately this is a web forms solution. So I dont have all the perks of MVC
It does get into the javascript method and gives the alert but won't go into my c# method. My previous experience of using this Jquery method is in an MVC website. Is it compatible with webforms sites?
Here is the code:
http://pastebin.com/Xdey4XTS
i want to make something like that
<cc1:AsyncFileUpload runat="server" id="upload"
onuploadedcomplete="Unnamed1_UploadedComplete">
</cc1:AsyncFileUpload>
<img onclick='upload.click()'/>
i tried lots of script but it doesnt work.
I 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>';
};
I have a web user control. That I load dynamicaly inside a modalpopup window using dynamic populate extender. User control has a external javascript file linked to it. Problem: I cannot make call to webservice method from this external javascript file. When I make a call -- servicename.methodname() I get servicename not defined error.
