Ensure Javascript Is Loaded Once Only?

Jan 6, 2010

I've been working in asp.net webforms and I've been making a UserControl that depends on a small bit of javascript which is in an external file.

I want to be able to put a reference to the javascript inside the UserControl to ensure that it gets loaded on the page, but the problem is that the UserControl can appear multiple times on a page so I only want the script to be loaded with the first instance of the UserControl.

Is there an easy way to do this in ASP.NET Webforms?

Javascript - How To Ensure Js Is Included In Ascx File

Feb 17, 2011

So the problem is the following :

i do have own user control. which has some javascript file in script tag included like this

<script type="text/javascript" src="../somefile.js" ></script>

or some javascript code directly on the ascx page. everything works if i place this control somewhere in aspx markup. but if i add this control to the page dynamically to some UpdatePanel place holder on postback (this is logic i can not alter), control renders itself and then i get js error message, which says that functions which are placed in somefile.js are not defined/are null. Why is this happening ? Is there anyway to force js including in this case.

the code amount is huge and i was not able to provide a simplified example with the same error,.

The script is included but somehow the functions are not defined. I'm novice to js, so is it possible that just the script is included but not executed, so the functions are not declared ???

The interesting is that if on some page my custom control is declared in aspx.

How To Ensure Validators Fire Before Call Client Side Javascript

Feb 4, 2011

I have an asp.net application with basic CRUD functionality. On a page where i am capturing customer details i have several asp.net validators to required fields. I have attached a JS confirm box on the asp.net save button for the form. The trouble is that when the user leaves required fields unfilled and clicks the save button, the JS confirm box comes up, when the ok button is clicked, the save method is called successfully and only after this happened do the asp.net validators fire and display that required information has been left out.

C# - Ensure Offsite Javascript Doesn't Impede Site Performance?

Nov 2, 2010

I need to include an offsite javascript file on my page, however I don't want it to be able to affect the performance of my site, in case the server where the javascript is on is down or not responding.

What I'd like to know, is if it's posible with javascript to make some sort of wrapper function to ensure that the page where the offsite javascript is hosted is responding within an acceptable timeframe.

I've considered adding the "defer" attribute to where I include the javascript, but that would as far as I know still leave the site hanging after the rest of the page is loaded.

If it's not possible to do in javascript are there any good alternatives?

My site is made C# asp.net.

Usercontrols - How To Add A New Javascript From A User Control Loaded By Callback

Sep 10, 2010

I'm doing a menu that loads levels dynamicly, when you click on a item the next level is loaded asynchronously. For each menu item I have a user control. Every user control is declared in its parent, for example, the "secondlevelcontrol" has the reference to "thirdlevelcontrol".With this level of nesting, I want to manage the asynchronous calls on every user control so, when the first level is loaded the javascript to load the second is loaded too. When the second level is loaded the javascript to load the third is loaded too.

To do asynchronous calls I'm implementing ICallbackEventHandler interface. As you can see in the examples, controls are added to the page as plain html. The method "ProcessOnLoadEvent" executes all lines of the "OnLoad" event of the user control.An example of the implementation is this for the user control of fourth level:

public string GetCallbackResult()
{
return _callbackRendering;
}

[code]...

C# - Ensure No Implicit Culture Settings Are Used?

Mar 24, 2011

I have some classes which can't make assumptions about de used culture. These classes should always use CultureInfo.InvariantCulture. However, I can't set the thread's current culture to CultureInfo.InvariantCulture, because other classes rely on <globalization culture="auto".

Is there a way to ensure some classes always use explicit culture method calls (like: Convert.ToDecimal(value, CultureInfo.InvariantCulture)) instead of assumed culture (like: Convert.ToDecimal(value)).Maybe my question it's not 100% clear: I'd like to detect all methods which have an overload which uses CultureInfo, but also one without the CultureInfo which uses the CurrentCulture.This includes implicit casts of numbers to string:

decimal value = 1.0;
string displayThis = string.Format("Costs: {0}", value);

The goal is to make sure some classes/methods don't assume anything about CultureInfo.

I have a standard createuserwizard control, which adds a new member to my membership database. All fine, except I need to ensure that the user checks the terms and conditions checkbox before the member is created in the code-behind page. I need this to be server-side, rather than client-side, so a javascript-reliant solution isn't a solution :)

The code-behind is like this:

Ensure Uploaded File Contents Cannot Be Recovered After Use?

Jan 18, 2011

I would like to make the contents of a file uploaded to a web server unrecoverable after it has been used. My concerns are:

When the file is uploaded, is it stored in a temporary directory (e.g. Windows Temp directory) and how do I clear all traces from there? Can the contents of the file be written to virtual memory and how do I ensure it is not or remove the contents once written? If I encrypt the file, would I still have to worry about the contents being saved to the Temp directory, virtual memory or elsewhere before the file was encrypted? Can I perform a secure delete in all the concerned about locations (temp, virtual memory, any others) and how do I do this? Are there any concerns I have missed or an alternate way to achieve the stated goal?

Check Textbox Value Against Records In Database To Ensure Unique Value?

Jul 30, 2010

When a user enters a value I want to check against the other values in the database before allowing the record to be inserted.

It is a nvarchar type column.

Is it best to use a unique constraint (if so, how) or what would be the way to programatically check to make sure this name does not exist. It is not a username, just a name value that will be used in routing.

How To Ensure User Accepts Terms And Conditions On Website

Jan 21, 2010

We're modifying an existing ASP.NET application. We added a Terms and Conditions page with an "Accept" button that stores that choice in the user's account data. We want to prevent the user from accessing any page when the user has not accepted the Terms and Conditions.

I think we want to do this by looking up the "accepted terms" value upon login and storing it in the session. Then we need to intercept every request and check for that session value. (If it's not there, we redirect the user to the Terms and Conditions page.)

Is the PreRequestHandlerExecute method the right place to put this check? This method also gets called on requests for stylesheets and images, so it doesn't seem like it was intended for this purpose.
