Architecture :: What Is Role Of Object Properties When Using Client Side Validations
Aug 24, 2010
I have been using properties and have idea that using properties with private fields we can implement validations and buisness rules in them.
But I am just thinking asp.net client side validation controls provide good strength and they provide good user experience as well. They can be used for any type of validation (using regular expression) on client side and their re-use is possible on server side. When validation controls are a must and they are powerful; is making properties not just wastage of time ?
Is there still some use of properties ?

In forms I need to do custo validations. Like if use select radio button that he is residing on current address for more than 3 than previous residance fields are optional but if he select (radio button) that he is residing on current address for less than 3 years than previous address fields should be requried. Requirment is to do these on client side.
how this can be done. Secondly can there be some way we just disable a validation group and all validations in this group may be turned to disabl ?

I have a website in ASP.NET (WebForms, NOT MVC) which has a survey form divided in several slides. Each slide has a next button that, obviously does a transition (client-side, not post back or remote request) to the next slide.In each slide I have several ASP.NET controls with their related validators. I want this validators to be triggered when I click the next button (or maybe when each input loses focus?).
I remembered ASP.NET doing client side validation on lost focus, but maybe I'm wrong... (I quit doing ASP.NET development about 3 years now, so I can't remember)UPDATE: It would be better to make ASP.NET trigger each validator when the associated control lost focus. I remember ASP.NET doing this (or am I dreaming? =P)

I've posted the same question in the Object Data Source forum. This is a link to it http://forums.asp.net/t/1554083.aspx. Maybe I should've posted here to begin with. There seemed to be some overlap so I wasn't sure which was the best on to post the question in.
I'm trying to get a better understanding of how I could've designed my app so that the Object Data Source could work with the properties of my business objects. Please read the other post to see how it's currently being done. Sorry for the link to the other page. I didn't want to post a bunch of duplicate information. I would love to get some suggestions for alternative ways of doing this.

Recently I met a problem when I try to use 'behavior' things with an Ajax Control.
I try to use an accordion's accordionbehavior on client side.But whenever I tryied
alert($find('myaccordionId').AccrodionBehavior.AutoSize) // prompt me: AccordionBehavior is null
or
alert($find('myaccordionId').AutoSize) //prompt me: 'AutoSize' is null or not an object
Although I can get
alert(AjaxControToolkit.AccordionBehavior) //prompt: is an object
I am using AjaxControlToolkit.dll(1.0.20229) and .Net framework(2.0.50727), I really wondered why I always get null for those object instead of proper value like what Ajax ControlTookkit Accordion Reference said to be [URL] am I missing something.

Is it possible to either access the properties, such as 'url', of a embedded media player object server side to change them? Or possibly dynamically create a new media player object with a different 'url' each time?
I am trying to change the property based off of a selectedindexchanging event of a gridview object.

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?

This is not a programming question per se, but rather an attempt to find the adequate technology to use for my objective. My mandate is to build an ASP.NET Web Application. However, on certain pages, some client-side information needs to be fetched by interacting with hardware on the client's computer, for example a barcode reader or an RFID tag reader. My first reflex was to think "ActiveX" controls with, perhaps, some AJAX coding to fetch the required values from said control. However, I am not sure if I am up to date with the latest tech trends. The solution I'm looking for will let me design a user control that plugs into my ASP.NET Web Application, lets me interact with client-side hardware, and can be automatically downloaded from the Web Application itself (I can't predict which computers will access my Web Application). Which technology(ies) should I go for?

I want to implement validations in setter of properties.
how I will do validations before setting value. but not getting what to do if passed value is not correct. Just not setting is not a acceptable solution as I want to return an appropriate message to user (in a label in web form). My example code is:
[code]....
A thought was to use return but it is not allowed.
Throwing error looks not good as generally we avoid thorwing custom errors.

I've created a ScriptService / ScriptMethod that uses a custom class as an input parameter but can't figure out how to create an instance of the object on the client side.I thought that when I used ScriptManager and Ajax before the ScriptManager registered my server side classes for me or am I completely mistaken?

I have a simple issue that most likely is syntax related. I have a table ("myTable") that is dynamically generated at PageLoad and can be actively changed during run-time. One of the features the user is able to make use of is adding additional rows to the table, generated via Javascript. The user also has the ability to save the table (and it's changes) to the database via button. Upon selecting the button, I run a function that creates a two-dimensional array to store values (Row, column). After using the .FindControl function, I was able to get the client-side changes to each of the textboxes and dropdowns and populate the array with it.
After checking the information, it does in fact store into the array the value in the textboxes at the time of clicking the button. Example: Textbox loads with 200 in value, user changes it to 400, when button is selected the value stored is also 400. This works great, except for one issue... The additional rows.
When checking back in the array, it appears that the arrays size is generated by the table that is created at PageLoad instead of the table at the time the save button is selected. Example: myTable is created with 3 rows, user adds 2 more rows to the table, save button is pressed. The array displays 3 rows instead of 5 rows, however.................................

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.

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).
