Jquery - Passing Back The Client Side Style / Class Change To The Server During Postbacks?

Feb 9, 2010

I'm dynamically binding tables and sub tables using nested listviews. On the client side I have a piece of jQuery that is toggling the visiblity of TRs witin the tables in order to provide a group expand / contract view option.

On postback I'm obviously loosing my class changes that I have applied via jQuery. I'm wondering what the best approach to maintaining these client side class changes is? I've considered creating a hidden input control per table to store the indexes of the visible TRs at the time of expanding them. The intention being to then look for the indexes during postback / rebinding and add the visible classes to each corresponding element.

Is there a better approach or some native method of passing back the client side style / class change to the server during postbacks?

Jquery - Options For Page With Matching Client-side And Server-side Markup?

Oct 17, 2010

Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).

What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked

Nov 23, 2010

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)

<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...

There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)

<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...

There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

Web Forms :: Combining JQuery Client And Server Side Errors In Same Summary

Feb 25, 2010

I am using JQuery for all of my client side validation and Asp.net validator controls for all of my server side validation. I am using an errorlabelcontainer to store the client side validations in a summary at the top of the page, which is the requirement. All works well. My problem is, I want to display the server side asp.net errors in the same errorlabelcontainer OR display all of the client side errors in the validation summary. Either way, Both errors need to be in the same place/div. Any ideas on how to do this? I thought of maybe using the asp.net validation summary as the errorcontainer in JQuery, but I cannot find the summary. This is what I have right now.

AJAX :: Passing Data To The Client And Back?

Aug 31, 2010

(I think) with using a data bound Custom Control on the server to get hold of my data (it will be part of a larger dataset) and to ultimately pass updates to the database. The bit I'm researching at the moment is passing that data to and from the client.One way to pass the data to the client is to use JSON within the Pageload event to construct a set of Javascript objects (one per row in the data). Is that the best way, or am I missing something?

Then, after the data has been manipulated on the client, I need to pass the rows back again so that the server side code can pick them up and process the updates. I've seen a suggestion on here that a hidden text field is one way to do that. Is it the best?Neither of my approaches seem to be at all elegant - and I suspect that I am missing something fundamental in ASP .NET AJAX!

Jquery - Non-server Controls And Partial Postbacks?

Feb 12, 2011

I'm inserting some non-server controls (plain html controls) dynamically into an update panel using jQuery.

If I do a full postback, I can get the values of those controls using Request.Form, however if I do a partial postback, I cannot.

Should I be able to get the values of html controls during a partial postback? Or only controls with runat="server"?

I am using non server controls as I'm playing around with facebox and file upload controls...

Server Side Control Hidden - Possible To Read Values Client Side

Jan 30, 2010

I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

JavaScript - Exposing Server-side State Through Client-side Controls

Feb 11, 2011

I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.

I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:

Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...
