AJAX :: Controls To Work On Client Side Only?
Jan 10, 2010
I have a page where i have the products names and their prices displayed using a repeater control. The sum of prices appears in the footer using a label. Each detail row has a checkbox, which can be checked unchecked to see the total sum of prices.
I have already done this using javascript.
My question is ,
"is there any better way like using any AJAX control to do this ? or this is the only way to do it without posting back to the server?"

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?

Using MVC 3 RTM and MvcContrib/FluentHtml version 3.0.51.0, I can't get the jQuery client side validation to work. Server side validation works fine, and returns showing the correct validation summary, etc. But the form post always tries to hit the server-side post controller action when it should have stopped on the client side to display the validation error.
I tried replacing the MvcContrib ModelViewPage with the default Mvc ViewPage and it still didn't work.
Here's my code:
Web.config has:
[Code]....
Site.Master page has:
[Code]....
View page inherits from MvcContrib's ModelViewPage:Here's the view page:
[Code]....
Here's the controller post action:

Here's the entity object with the Required field:

In my project, In gridview i want to add a client-side confirtmation for deleting a record. Everything seems right, browser asks for confirmation, after pressing "yes", nothing happens in gridview as well at database. What's the missing point ? Also in gridview, after pressing edit button "ArgumentOutOfRangeException was unhandled by user code" exception occurs
<asp:GridView ID="grid1" runat="server" DataSourceID="sqlSource1" DataKeyNames="id"

{
if(e.Row.RowType == DataControlRowType.DataRow)

I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.

I have studied Phil Haack's post [URL]about custom validation, however, I can not get this to work for my case. I need something like the "PropertiesMustMatch" validator in a default MVC2 project generated by Visual Studio.
None of my custom javascript gets called. I am registering the custom adapter in Application_Start using DataAnnotationsModelValidatorProvider.RegisterAdapter(....). In the DataAnnotationsModelValidator derived class, GetClientValidationRuls is never even called.
What is going on here? Maybe this type of validation where your validation attribute has to be applied to a class, not a propety, does not yet work with the RTM release of Visual Studio 2010.

Im using some animationExtenders in my project. The thing is, the objects to be animated are created programmatically, hence i need to also build programmatically the javascript code that will interact with them.
It runs properly but, when i interact with these animated controls and the javascript functions are supposed to get to work, i keep getting the usual run-time error saying that the javascript functions are not defined. But, if i check the final html code generated, i can see how all the controls i built programmatically are there ,as well as the script.
Tried both RegisterStartupScript and RegisterClientScriptBlock, no luck.

I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?

Something is wrong in ASP.NET MVC 2 on client side validation. If I have form for create records in database and all fields are required, validation is triggered only then when I write something in field and delete it. If I go to field, stay this field empty and press Tab key validation isn't triggered.
Here somebody else write about the same problem: [URL]

In my view data class I have a List.
[Code]....
I have all the properties of the class Person as required using Data Annotations.
[Code]....
In the View I loop the List like this:
[Code]....
Generated HTML:
[Code]....
Result:
Does not work at all.
Other things I've tried:
Tried using these HTML Helper methods instead:
[Code]....
Generated output:
[Code]....
Result:
Interestingly, when I trigger a validation on the first textbox, it fires simultaneously for all of the textboxes. The rest of the textboxes do not trigger validation at all.
Looking at the generated id and names for the textboxes and their corresponding error text span element, they areall identical.
Anyone figure out how to use Client Validation with Data Annotations with a List in the view data,
supporting Model Binding?

I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?

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.

I have a text box in which I want only digits (either decimal or whole numbers). I have applied Required Field Validator and Regular Expression Validator on it.I have an Image Button, by clicking on which, I want this validation to be performed. But when I build the code, and clicks on Image Button, these validators do not work and I am redirected to the server side method of Image Button and after completing the execution of server side method, control comes to these validators and client side validation executes.I am fed up by finding solutions on Google and unable to find any solution.Please tell me of anyone of you know the solution that why server side code is running first and client side validation is executing after server side code execution.

How to change gridview by datalist in this example? [URL]
View 1 Replies
Jan 20, 2010
I've a GridView bound to an object data source which gets data from a remote server. The GridView is inside an AJAX UpdatePanel. For each GridView row, I have a status data item for a person's status(like busy, free, etc.) and I need to show a running timer since a person has been in the current status. Different persons can be in different status at different times and so running timer for each person needs to be different and should be reset when a person changes status. Is it possible to show such a running timer for a cell in each row of a GridView and manipulate it differently i.e. start, stop and reset each instance individually?

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...
