Is there a way to assign/pass/copy a javascript variable to a server side variable in C#? For the sake of argument, let's say that I was able to parse some JSON for variables that I want to store and assign them on the client (ie. var = FirstName and var = 25 and var = someDateTime, etc) .

I'm using DataAnnotations as well as server-side validation logic.
Is there a way to show DataAnnotation's client-side validation errors in the ValidationSummary, as it shows when returning from server validation?
I know I can use ValidateMessage and ValidateMessageFor next to elements, but the spacial design of the form I'm working with doesn't allow for anything other than highlighting the HTML element, however, I would still like to have a message saying what's wrong.
If I place ValidateFor's alongside ValidationSummary in order to mimic a ValidationSummary during client-side validation, they both appear when returning from a failed server side validation.
I have some rendering logic for custom markup (a'la bbcode, but not bbcode). So that when I'm getting the stuff from DB I'm then calling MyRender.ToHTML(model.text)... Now what I do today is I just have a form below and I do a post and add the item and return the same view. My question is - how to do it with ajax? Should I create a control and return HTML a'la winforms? Is that sexy? How do you do something like that? Or should I drop it? Maybe duplicate the rendering logic with javascript?
View 1 RepliesI have a SQL Server 2000 table that has an insert trigger that e-mails the user when a record is inserted for them. i want to include a link to a page that will disply a list (datagrid) of their records only. What is the best way to do this? The trigger is already completed and currently includes a link that displays all records but I want to be able to narrow that based on the user.
View 1 RepliesWhile working through some demos today I managed to trick VS 2008 somehow and I cannot access any server side events or variables in the code editor window. Hopefully
this screenshot will demonstrate exactly what I am missing. No matter what control I pick from my source I get the same drop down items overhead. What is quite weird is that when I drop new server side controls onto the source editor I can set the tag attributes for the events, but when I double click that event there is not an automatic created event handler with the same name created for me. Also, on the property pages there is no events image button (the one with the lightning bolt). The only property page items which have the events image button (lightning bolt) are the ajax toolkit controls. Already tried the "import all settings - VB Default" to blast away everything and no luck..
I have a code behind page with two functions that return two counts (iCount and iCount2). In my repeater table I can display the results of the functions just fine, but now I need to do some conditional logic based on the results of the functions, eg:If iCount =>3 AND iCount2 =>1 Then
View 6 RepliesI have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.
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...

I'm working on developing a custom control to select items from a predefined list. This is accomplished via 2 ASP.NET ListBox controls, with a few buttons to trigger the movement of ListItems from one ListBox to the other (lets call these ListBoxes lstSelected and lstDeselected).
This is easy enough to do in ASP.NET or JavaScript independently: I have both working. However, if modifications are made via JavaScript, ASP.NET retains no knowledge of this. Is there any way to register the creation of of options in a select tag without AJAX?
I've got a function I wrote quite some time ago that works fine, but I'd like to speed up the process and lessen server load by doing the same job in Javascript.I seem to be able to GET textbox values ok, but I can't seem to SET textbox values (I'm'-a JS noob).

I'm trying to create a JSON object on client-side and pass to a server-side function. Then instantiate it on server-side using JSON string representation.
So I create jSON object on client-side
var myJsonObject = {
"arg1": var1,
"arg2": var2
}
and pass it in to
WebForm_DoCallback(controlID, myJsonObject , null, null, null, true);
When I try to retrieve this JSON object on server-size I get as a string representation of JSON [object Object]
So in following server-side function, the argument value is [object Object]
public void RaiseCallbackEvent(string jsonObj)
I was expecting a string representation of JSON object. How do I pass in a string representation?
I am new to MVC, i tried to pass the viewdata value from Index action of homecontroller to the textbox i have on Index.aspx.
I am getting the view with the label and the textbox but i am not able to get the value that passed on from the controller
The below is the .aspx file
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
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");

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.
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?
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?

I was having problems inserting a string into the following tag:
<tr id="rowBulkOptions" style='<%# sBulkOptionsRowStyle %>'>
Don't ask why I'm using tables :) sBulkOptionsRowStyle is a Public string in the aspx.vb file. Seemingly the only way I can get this to render is to put Page.DataBind() in the Page_Load, Page_PreRender etc.. However this causes me problems because Page.DataBind() binds all controls on the page. I could use <%= BUT another part of the code inserts controls into the page and apparently you can't use <%= and insert controls. Is there a way I can just say 'look, put sBulkOptionsRowStyle into the page ?

but I am rather confused about what to invest in. I heard that server-side code translates into client-side code. So, if you have an .aspx file, it will be converted to HTML/CSS/JavaScript. I have experience with the latter three technologies put into a rather dull text file and rendered by a web browser. My question is how much HTML/CSS/Javascript coding would I have to do when server-side programming? In other words, can someone using ASP.NET program purely on the server side and not bother to write for the client side? Of course, I don't care about server-side being translated into client-side, but I am wondering if client-side programming needs to be done explicitly and to what degree.
