I am using ASP.NET MVC and jquery. I would like to implement preview functionality to a form. i.e. I have a form with number of fields for example name, address etc.. Before the user submits the info, he/she can preview it as to how it will appear on the site. how I could implement this in a cleaner way? I have tried regenearting the html on click.. but it's very messy.
View 3 RepliesI have to implement an image upload functionality in asp.net. The method I have followed works like this :-
Submit a form containing an <input type='file'> element and set the target of the form to a named iframe[to give the impression of a Ajax request/response ]. The aspx file which this form is posted to, writes the image into the response as Reponse.Write("<img src='location'/>"); The image displayed is due for cropping (where i plan to use JCrop).
What I would like to know is : Is there another way to display the image in a <div> may be, rather than in an iframe which I think is far better than this approach.
I want to implement a forgot-password feature in asp.net mvc that allows users to reset their password, and have some questions in this regard: Lets say that before allowing users to reset their password, I want to verify some extra information such as their first and last name. This info is not stored by default in the table created by aspnet_regsql. What is the recommended approach to address such issues?
Should I store this kind of info in a separate table, and use table joins to verify OR should i modify the schema of the table generated by aspnet_regsql (how?) so that I don't have to use joins? Do I need to write a custom provider OR would that not be necessary? I have read at places e.g. in this post that instead of emailing a temporary password, an alternative is to email a URL that when clicked allows users to change their password. How is this done? How to ensure that the URL expires after 1 hour?
I'm considering going at this myself because my requirements are particular and highly customized:
The grid is bound to a collection of complicated objects, each of which may contain child and grandchild objects. Depending on data and context, the template'd cells vary from TextBoxes to ComboBoxes to Calendars to a combination of controls.TextBox cells have Google-style auto-complete functionality. Also each TextBox cell can expand into a small TreeView pane that allows hierarchy-navigating selection of a value should auto-complete be insufficient.Values from other controls can be drag-and-dropped into cells.Columns are re-sizable and re-orderable. Clicking their headers sorts data.All of the above is AJAX / client-side / Web 2.0 of course.
Has anyone built anything similar from scratch? Or used an effective tool to accomplish this goal? How well would Telerik meet my specs? Is it right to have the hunch that something this specific is best done by taking a Microsoft GridView and extending it myself?
I want to have an upload functionality for uploading large files -- as large as 1GB. I see some sites successfully implementing reliable upload functionality without using any upload clients e.g. ActiveX, Java, etc. Some suggest, the secret is sending the large file in smaller and more manageable chunks to the server. If that't the case how do I handle that?
View 4 RepliesI've started some preliminary work on getting a Google-like search functionality into my app - ive never done anything like this before so i thought id be a good idea to run by what im thinking of doing at a high level
1) Using MS SQL 2008 w/ Full Text Search Enabled
2) ASP.NET MVC 2 app is using the Repository pattern, with Linq to SQL for data access I'd like for the user to put in one giant text search value, and the full text to do a search over multiple tables and return a mixed result (Employees, Organizations, Offices, etc)
3) I have a simple stored proc that does a Full Text Search on *one* table that looks like this:
[Code]....
4) My Linq to SQL datacontext calls this SP and which works well enough, i have no inflection or ranking going on but ill add that in later...
Q: How do i handle searching over *multiple* tables, doing some digging around it looks like Full-Text doesnt really allow for searches to span over more than one table - which kinda sucks..although ive seen some workarounds
Q: Is it ok to do a Full Text Search for every table i plan on searching through, and combining the results at the business layer (maybe using rank as sort)? I've heard of things like LUCENE but id really not like to do that at this time.
I want to know how to show A jquery lightbox modal from a link placed inside the listview. My Code Is As Follows.
[Code]....
I am using server side code to assign image to the image control.
And some javascripts to assign the href of anchor tag.
The Problem which I am facing Currently is as follows:-
If I am clicking on the image of 1st row then the jquery light box modal is working perfectly but when i am clicking on the image of other rows then its not working.
What I think, when the listview tries to repeat the rows the id of that anchor tag & image control is getting changed and the javascript which I am usiong to assign the href attribute of anchor tag, cannot find an id for that same anchor tag and the image control.

View 2 Replieswhat is the correct way to pass data through the AJAX calls and have it be model-binded into an object inside my Controller Action?
So far, I've read in some places that jQuery sends data in key-value pairs, so I don't have to do anything extra, while in other places, I've read that I have to first use a JSON deserializer and then bind the result. I've currently implemented my Controller Actions as ones that accept HTTP POST.
I am required to create a functionality like the "Top Tweets" of www.twitter.com,I started out thinking that it would be simple and just use a update panel and a timer with a gridview in the middle of it and just have it update every few seconds. but as you can see the problem here it updates the whole entire gridview and I just want to go ahead and add the new updates to the top of the page and not refresh the whole entire feed everyfew seconds.
View 5 RepliesI am attempting to implement the suckerfish menu found on this tutorial. I get "object expected" error from the sample javascript:
$(document).ready(function () {
$("#nav-one li").hover(
function () { $("ul", this).fadeIn("fast"); },
function () { }
);
if (document.all) {
$("#nav-one li").hoverClass("sfHover");
}
});
I have imported the JQuery using:
<script type="text/javascript" src="~/Scripts/jquery-1.4.1.js"></script>
The JQuery import is in the page header. The javascript is just inside the <body>.
It would be nice if I could tell which object is having the issue instead of being pointed at this block of code. I'm new to JQuery and beginner level javascript.
UPDATE
The start of the menu:
<ul id="nav-one" class="nav">
<li>
<a href="#item1">item 1</a>
<ul>
(I think the #nav-one points to the id of the menu "nav-one").
And I believe this css covers the "sfHover" part:
#nav-one li.sfHover a {
background: #ccc;
color: #000;
} [code]....
I have noticed that in Google web reader (that lets us read RSS feeds on the web), the page does not seem to load ALL the feeds. Instead, as I scroll down, I can see more and more feeds (and the size of the scrollbar increases if you know what i mean)
I assume they do this by finding the position of the scrollbar and do an AJAX call. Is this correct? How would I do this in ASP.NET?

I have a problem with JQuery when using update panels. My page is structured like this:
Text search
Login Update Panel
Login form
End of Login Update Panel
For clarity I have remove all other page objects. As you can see the login form is inside an update panel, the text search is not. Both of these objects rely on jquery to function correctly (assuming javascript is enabled). In order to persist the functionality after postback with the login form, I use the PageLoad() function. This works ok.
I tried the same with the text search but it doesnt work. I presume its because it isn't inside the updated update panel. At the same time the functionality disappears using document.ready() and I can't understand why it works with neither rather than one or the other.
What is the best way to use jQuery Templates with GridView to achieve similar functionality of an UpdatePanel, such as add/edit/delete data without PostBack?
