MVC :: Displaying Actual Exception In AJAX.BeginForm
Apr 19, 2010
I have a situation where I need to display an actual error/exception that happened during processing after the OnFailure event of the AjaxOptions class fires. Is this possible? I know the OnFailure allows me to write a method that can display a custom error message. Instead of this error message, I'd like to display the actual exception.
Here is my code for the ajax form init.:
[Code]....
And then here is my Javascript method:
[Code]....
As you can see, I am currently displaying an errorMessageDiv which has the code:
[Code]....
I would love it though if I could show them the actual Exception message (which i have wrapped) so I can tell them the exact cause of error.
I have a very simple app where a user enters 2 text values and presses a button, I want a confirmation message to be displayed on the same page however it keeps redirecting to show the partial view as a full view.
This is my home View:
[Code]....
This is my ContactController:
[Code]....
And finally this is my Confirmation PartialView
[Code]....
This is using MVC 3/.Net 4, I have downloaded an MVC 2/.Net3.5 sample project from the web that is doing exactly the same which works fine. What am I doing wrong?
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.
<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?
Normally we have to use scriptmanager control on our page whenever there is a need for update panel and other ajax controls. I want to know about actual function of scriptmanager.
I am trying to get a number returned from a webservice that executes a stored procedure and gets the record count from SQL. I then want to display an alert with the record count to the users, When they click on 'Check records' button. For now I am just using the alert to see if I could get a number back, here the code I am using:
It just returns [object] rather than the actual data in the alert box in IE 7.0 however it works fine in Firefox and displays the valid record counts like 0, 10, 36 etc...So there some thing else I need to do to handle the JSON data in IE but
I'm trying to use Ajax.BeginForm() to POST A Json result from my controller (I'm using MVC3). When the Json result is called it should be sent to a javascript function and extract the object using:
[Code]....
View
[Code]....
The strange thing is that the exactly same code works in MVC2 - Is this a bug, or have I forgot something?
I'm using Ajax.Begin form with MVC validation. When I'm in the server code and there's a validation error then ModelState.IsValid is false and that's good.If I have OnSuccess defined in my AjaxOptions why does my OnSuccess function get called when the ModelState is not valid?In my parital view:
using (Ajax.BeginForm("ProfileEdit", new { controller = "Account", action = "ProfileEdit", id = ViewData["ProfileID"] }, new AjaxOptions { UpdateTargetId = "profileEdit", OnSuccess = "OnSuccess" }))
In my controller I always just return PartialView();
I just want to display a success message in the view but OnSuccess gets called even if there is a modelstate error. If I try to throw a HttpException then I lose my ValidationSummary and other error messages.
To work around, I'm setting a ViewData["Success"] and displaying the message div in the .ascx if ViewData["Success"] != null.
I have RemoteValidators working correctly on Html.BeginForm. However when I turn this from in Ajax.BeginForm and perform following:1. Type in Textbox whose viewModel Property is bound to a Remote Validator RC2 MVC3 2. Press Submit Button immediately.3. What I observe = data is saved before it the validation completes. 4. On Server UpdateModel works and it finds no issues (even though the remote Validator would have noticed the problem).
so I am using a foreach loop to iterate through comments. The comment section is wrapped inside "Comments" div. My function **DeleteComment** fetches comments again once you delete a comment and rebinds it to the control. However, after you delete a comment, anytime you try to delete another comment, the commentId of the very first deleted comment would keep getting passed to **DeleteComment** function instead of the passing the commentId of the comment you are trying to delete. If you refresh the page, then you can delete ONE comment again, and the same problem if you try to delete another.
I am trying to make an AJAX Form work correctly with Client Validation, but I can't seem to figure out how to make it work together.Currently I have a view like this:
[Code]....
My model:
[Code]....
The client validation works on the Required and Stringlength attributes, but if I put an incorrectly formatted email, it still returns successful. Is there a special way to do the regular expression attribute? Or am I doing it wrong?
Using the following Ajax.BeginForm, it`s not reaching the controller. What is wrong with the following code? The $('#editForm').submit(); is reached but after that, it doesn`t reach the action.
can i have more than one AjaxOptions in Ajax.BeginForm targetting different controls?Actually I want to exchange data between two listboxes placed in a single ajax.beginform.
I'm using VS2008 and .net 3.5. I want to invoke a javaxcript hide() when user clicks the Search button and before running the action code. Previously I didn't need to run the javascript yet I use the (Html.BeginForm.
After I modified the code to use the Ajax.BeginForm I get the Error below. "SearchSurveyResults" is my action's name and "SurveyResults" (The file name is SurveyResultsController.cs )is the controller name that contains the action. The Javascript that I want to run when user clicks the Search button is hide().
What am I doing wrong here? Why is it looking for a /SurveyResults.aspx file? SurveyResults is the name of my controller where the form submit should send ti one of its action.
<% using (Html.BeginForm("SearchSurveyResults", "SurveyResults", FormMethod.Get, new Dictionary<string, object>() {{@"class", "communitysearch"}})) { %> <fieldset> <legend>Search by Keyword</legend>
[Code]....

I have an Ajax form with a single input and a button. On submit, the form should only post the entered value to an action method. My form is correctly posting to the User controller's Log method but when done, the page redirects to /User/Log.
I'm running into an issue with an async call to the server that only works one time, then it appears to become a synchronous call. Let me try to explain.
It's an MVC 2.0 site, using ASP.NET and Ajax. I'm using the Ajax.BeginForm helper, like so:
<% using (Ajax.BeginForm("Start", null, new { virtualMachineId = xyz }, new AjaxOptions { UpdateTargetId = "VirtualMachineForm", OnBegin="OnStartingVm" } )){
[Code]....
Within the updateStartingStatus function, the first part runs every second, every time. However, within the Ajax call, the success result works every second on the first time only. Then on the second time I click on the start button all of the requests queue up. After the starting has completed, about 20 seconds later, I get a bunch of alert windows back to back. So, I can tell that updateStartingStatus runs every second every time, but the ajax call appears to switch to become a sync call after the first time.
I have to fully close it and open it again. The same occurs in IE and Chrome.
One more thing to note is that the updated div (VirtualMachineForm) contains most of the page, including the button being pressed. So it basically replaces the page from under itself. Not sure if that would cause any issues.
Additionally, if I debug in Visual Studio 2010, the call isn't made to the controller action when the issue occurs. So, it appears to be something client-side. I've ruled out any issues server-side.
I got a problem with client side validation not firing, after reading many posts I believe it as to do with the HTML being loaded "afterwards". But I can not seem to find any solution.You got any ideas how to solve it?
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.
Currently I have a comments section integrated into a blog I am writing. The comments are Ajaxified, when you post a comment the comment list auto updates with the comment you just added. Everything is working great but I would like to do some cleanup after a comment is successfully posted. Specifically I would like to disable the textarea and submit button which I would have no issues doing through javascript by using the AjaxOption OnComplete parameter. To avoid double posts or just plain abuse. I know I will need other safegaurds as well but this is my first step. The thing is Ajax.BeginForm does not give the form an id or name so I can not reference the form in javascript. Is there a workaround here? Can I disable these form controls from the controller?
