Dynamic Javascript in Ajax Partial View

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :ASP.Net
I have a partial view which uses Ajax.ActionLink to perform paging.  The AjaxOptions in the link identify the update target (a div on the main view) and some javascript to run OnSuccess (in the partial view).  The javascript must be in the partial view since there is some information in the partial view required to properly wire up the jQuery in the javascript.  This isn't working as expected.  The sample below is the minimum code to duplicate the behavior I am seeing: Controller: private static int count; // // GET: /Home/ public ActionResult Index() { ViewData["Test"] = count++; return View(); } [HttpPost] public ActionResult TestPartial() { ViewData["Test"] = count++; return PartialView(); } View:  <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Index</title> <script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script> <script

AJAX partial update of a partial view



I have an application which is using jQuery tabs. Each tab renders a partial view asynchronously, however some of these partial views need to also be partially updated. For example, one of them displays two tables of data, and one of the tables allows the user to filter the results, so I want to do a partial update of this one table, but I'm not sure how to accomplish this. I've been looking at Ajax.BeginForm, jQuery.post, and jQuery.load, but I'm not sure what the right approach is.

Thanks for any help. :)

Ajax Enabled Gridview using JavaScript in ASP.NET

Before explaining the article, I would like to thank all readers who read my article and voted for it. Your appreciation for my article gives me strength to write more good articles. Hope in future I will get your valuable comments and suggestions. Now I won't waste your time and come back to the topic. I have written this article on 'Ajax Enabled Gridview Using JavaScript in ASP.NET'. In this article, I will show you how to make a Gridview using a simple HTML table, JavaScript and XML HTTP for Ajax call without using any ASP.NET control.

Using Code

GridView Javascript Click Row and Ajax

This article shows 2 common tasks with the ASP.NET GridView: Binding a List (generic) of objects as DataSource and on clicking a row, getting the values of the selected row by a javascript function. In the example a List with User-objects is displayed. On clicking a row containing the data of a User-object, the Id of the object is used to get the address of the user by an Ajax-call and display it in a details-field.

partial view, 2 controllers



This is my first visit to the forums, I hope someone here can help me


I'm writing a small webapplication for creating repair tickets and adding comments, really basic

now I'm writing this in MVC2

So I have 2 controllers, 1 HomeController that does everything related to the tickets (listing tickets, creating new ones, editing) and 1 controller for the comments

the edit view for the homecontroller contains a partial view for /comment/create

so /home/edit/ticketnumber can edit the title and status of the ticket on the left side of the screen, the right side of the screen contains the partial view for adding comments

this is done like this:

Html.Renderaction("Create", "Comment");

but if I look at the generated html code when running the app, both save buttons go to /home/edit/ticketnumber

so the comment is never saved.


I hope this makes sense and that someone can help me solve this

Need help regarding C# / AJAX Dynamic Controls creation


radiobuttons is assigned before page init.. 

public partial class Default : System.Web.UI.Page
//Assign values as a specific Dynamic WebControl Creation.
List<RadioButton> radioButtons = new List<RadioButton>();
List<CheckBox> checkBoxes = new List<CheckBox>();

Then I created a class that would dynamically create a table containing the available flights depending on session.. (See CallPageLoad())

The placeholder and button is inside the UpdatePanel...

on the button inside the update panel, (btnSelect)

i have this code which works... 

protected void btnSelect_Click(object sender, EventArgs e)

Label1.Text = Convert.ToString(radioButtons.Count);

It detects the number of radiobuttons that were dynamically created...

But when I use the following code inside the BtnSelectClick event...

//PLS HELP.......
foreach (RadioButton button in radioButtons)
if (button.Checked == true)
Label1.Text = "You select... " + button;



It does not work even though t

ASP.NET Proxy Page - Used for Cross Domain Requests from AJAX and JavaScript

The article ASP.NET Proxy Page - Used for Cross Domain Requests from AJAX and JavaScript was added by Aamir Hasan on Thursday, August 19, 2010.

One of the pain points with developing AJAX, JavaScript, JQuery, and other client-side behaviors is that JavaScript doesn't allow for cross domain request for pulling content. For example, JavaScript code on www.johnchapman.name could not pull content

Disable filtering on a Dynamic Data list view.


I have an entity set of NotificationTemplates, and each one of these has a collection of zero-many SmsTemplate entities. When editing or viewing a NotificationTemplate, I have a link to View SMS Templates. That link takes me to a List view for the SmsTemplates entity set, filtered for the NotificationTemplate I was viewing.

How can I prevent the user changing this filter to show SmsTemplates for another NotificationTemplate? That is, I want the filter, but it must be read only. The drop-down just mustn't drop down, it must just display the name of the NotificationTemplate that these SmsTemplates belong to. To view SmsTemplates for another NotificationTemplate, the user must click View SMS Templates from that other template.

This was originally asked by myself on SatckOverflow at: http://stackoverflow.com/questions/3514373/disable-filtering-on-a-dynamic-data-list-view

Using Ajax AutoCompleteExtender on dynamic fields



I have quite a problem with a form that contains an autocomplete function. The page is an aspx page with c# codebehind.

On the form there is an address field that the user can type in any string address. This field is using an Ajax autocomplete extender, which suggests roadnames to the user. This works fine.
Furthermore the user has the option to add multiple address fields when clicking a button. This works fine now with Jquery. Jquery copies the table which contains, besides other fields, the address field, and "paste" it underneath the existing adress field.

Problem is, how do I attach the Ajax autocomplete extender to the address fields that gets added? Or is there another workaround to make all these fields have this autocomplete function?

Here is my simplfied code:

aspx page:

<td width="200">
  <asp:TextBox ID="TextBoxStopRoadName" runat="server" Width="200"></asp:TextBox>
      <asp:AutoCompleteExtender runat="server"

Dynamic gallery using ListView and AJAX


I want to create a gallery where on top there will be a normal view of a selected image and below a horizontal listview in order to select an image. Both in separate ajax update panels.

When i debug i get the following error "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" and highlights the "ImageButton imgbtn =(ImageButton)ListView1.Items[ListView1.SelectedIndex].FindControl("ImageButton2");" of my code behind file

Can anyone help me? Thank you in advance!

MVC with Javascript/AJAX scenario



I'm a rookie with Javascript/Ajax and I was hoping someone could provide an code example or advice of the following scenario:

1.  User clicks a button on the view

2.  Display a message "Waiting to be processed".  (Currently using Javascript)

3.  Execute the action method to retrieve some data.  (Call made from the Javascript)

4.  Return the same view.

5.  Open up a new browser window with a URL that was obtained from the action method.

How do I open a new browser window automatically after the action method is complete?  I was previously making the following call (Process.Start(http://www.yahoo.com);) in the action method but I'm running into issues with it.  I'd like to use Javascript/Ajax.


If it helps this the javascript code that is run when the button is clicked:

function runReportMessage() {
    document.getElementById("runReport").innerHTML = "Running the report. Please wait";
    document.getElementById("btnRun2").disabled = "

create a dynamic view on code

How i can create a new view on code (on runtime) if this view dont exits?   Thanks
