AJAX :: How To Call A Server Side Method From Client Side
Jul 16, 2010I 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?

C# - Apply Client Side Validation On Fileupload Control To Check Filename Contain Special Character?
May 24, 2010I am working on ASP.NET3.5 platform. I have used a file upload control and a asp button to upload a file. Whenever i try to upload a file which contain special characterlike (file#&%.txt) it show crash and give the messeage "Server Error in 'myapplication' Application." A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. how can i prevent this crash using javascript at client side?
Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked
Nov 23, 2010I 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.
AJAX :: Registering Client Side Script To Interact With AJAX Controls
Sep 13, 2010Im 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 feel MSDN magazine sometimes contains a lot of "marketing" so I'm interested in opinions of real developers. Does it worth it? Do you plan to use it?

View 2 RepliesAJAX :: Using Extenders To Make Client-Side?
Sep 10, 2010I am developing a web application that needs to retrieve, display and write data to an SQL database. I'm trying to use AJAX and Javascripts in order to populate fields, lists and data, and to have button and calendar controls on the page that can update the page without refreshing and losing the data page. Therefore, it's necessary that I find ways to doing as much as possible client-side, without page refreshes.
Now, for security purposes, I've heard that there's a method for retrieving a copy of all relevant data from SQL at loading time, keeping a copy of it, perhaps on a separate page, and send-retrieve-display this data on my page, and then, at Submission time, write this data back to the Server. This is to minimize hits to the Server and to preserve data integrity. I've heard that doing this is called using an Extender, but we can't find examples of how this works so far.

"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?"
