View 2 RepliesJavascript - Execute Some Custom Code Before AJAX Request Is Sent
May 10, 2010I have a drop down in an ASP.NET page. Whenever the value of the drop down changes an ASP.NET AJAX request is made to the server. I also attached a jQuery "change" event handler to that list to execute some code when the value is changed. So, probably two different event handlers are being attached to the same drop down, and it's causing some problems, i.e., sometimes wrong drop down values are sent to the server. I don't know why is this happening but I think attaching two different event handlers to a same drop down may be the reason.
Can anyone tell me what is the problem here? If what I guessed is true, then is there any other way to execute some custom javascript code before asp.net AJAX request is sent ?

Getting QueryString From Request Or Javascript?
Jan 19, 2010In aspx I have a querystring - www.mysite.com/enter.aspx?dest=#. When I click "enter" I go to main.aspx. I want to get this "?dest=#" in main.aspx with a request.querystring or something in javascript. I need to use the querystring in javascript in main.aspx for another action.
let me explain in detail - I have enter.aspx page that shall load with a querystring - www.mysite.com/enter.aspx?dest=#. Now when i click the Enter button on Enter.aspx page, it shall goto Main.aspx page. When main.aspx page loads i want to write small javascript in main.aspx that shall get the querystring from the previous enter.aspx page and give it an if condition. so if (request.querystring('dest=') > 0 window.open ('a1.jpg') this above code needs to be redesigned so it can work. how can i do this. i tried window.location.href.indexof('dest') , nothing happened.
Javascript - Initial Request Will Not Set Back To Re-enabled?
Oct 12, 2010Within an ASP.NET AJAX UpdatePanel on my page I have a submit button which has some custom javascript validation applied which set a global _cancelGeneralSettingsUpdate flag depending on the results of the validation.In this case the variable _cancelGeneralSettingsUpdate is correctly set to false but the initializeRequest function is not called before the page attempts to postback via AJAX, causing the postback to fail. I need to be able to have postbacks succeed once the invalid input has been corrected and the user clicks the submit button again. Unfortunately I do not seem to be properly wired into the PageRequestManager pipeline once postback has been cancelled. If I refresh the page, everything works again, but cancelling the postback via args.set_cancel(true)

View 3 RepliesCan Pass Ajax Request With Header
Jan 13, 2010While using Ajax in web applications we use XML to transfer the data between server and client. However XSS validation comes into picture, So questions are,1. Is passing XML like this is correct?2. Are we exposed to security issues if we turn off XSS validation?3. Can passing Ajax request with header (content-type = application/xml) solve this problem ?JSON is also good approach to transfer the data but that to invoke XSS.

Ajax Request Times Out (or Is Really Slow)
Nov 15, 2010My basic structure is that I have a table on a page, which I want to reload without refreshing the entire page. So on clicking a button on the page it fires of this:
function RefreshMissionsAjax() {
//fade out the old table.
$(clientID('MissionsDisplay')).fadeOut(500);
//request the new value from the page (calls the GetIncompleteMissions() method in the MissionViewer.aspx.cs page)
$.ajax({
type: "POST",
url: "MissionViewer.aspx/GetIncompleteMissions",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
$(clientID('MissionsDisplay')).html(msg.d);
$(clientID('MissionsDisplay')).fadeIn(500);
},
error: function (xhr, ajaxOptions, thrownError) {
$(clientID('MissionsDisplay')).html('An error occured while trying to refresh the page data.');
$(clientID('MissionsDisplay')).fadeIn(500);
}
});
}
And I have in the code bedind of an aspx page:
[WebMethod]
public static string GetIncompleteMissions()
{
return GetHTMLTable();
}
This method just grabs some data, and creates a html table - nothing too fancy. When the returned table is small (a dozen rows or less) then it works like a charm. But when it gets larger, it takes a long long time. At 100 rows it can take 5 minutes to render the table. At 1000 rows I have left it for 30 minutes and nothing will happen after the fadeout. (NB - it loads fairly quickly on the pageload, before the ajax refresh is used, so it is not the actual server side creation of the table thats the problem).
This is my first real attempt at doing something like this, so I dont know if this is the best way to do it - it was just something i pieced together that worked great when i was testing with small datasets. Now, not so much.

Page.User Is Null During AJAX Request?
Jul 26, 2010I'm using the MVC2 framework and one of my views has a bit of conditional logic that gets the Page.User.Identity object and does a comparison with other values to determine what to display.That all works fine on the initial page load, but when I make an AJAX call to get partial page updates (I'm doing this all manually with YUI3, not the .NET AJAX stuff) the Page.User object is always null.
View 1 RepliesAJAX :: Make A SOAP API Request - PayPal Using 3.5?
Jan 20, 2010This is so frustrating to me. I'm doing this via standard .NET 2.0+ web services (not WCF). My application is in .NET 3.5 but I'm just adding a service reference. I've not done any SOAP WSDL sending before. I've used NVP which to me seems much more error prone and burdensome because you have to create all the wrappers yourself and if any of that third party API changes, it breaks your code. I have not a clue how to make a call using the latest PayPal WSDL. I added the service reference and I see proxy classes such as [className]Request and [className]Response but how do you actually make the CALL and send the request over the wire?
I see people have used the outdated (.NET 1.1) PayPal SDK. We do not want to use an SDK just to send a request. Isn't it much easier nowdays in .NET when using any SOAP API to invoke the request? People for example using PayPal are relying on a caller class from that SDK but again it's way, way outdated. So onto today, .NET 2.0+, I thought that you don't need all that plumbing anymore?
How would I do this? I see no good documentation on the net period on .NET 2.0 or 3.5 web services especially SOAP and it's frustrating. Sure add the service reference, use the WSDL and proxy generated class wrappers but outside this HOW to make a request is impossible to find. I'm seeing legacy ways of doing this in .NET and then I hear this is all done under the covers for you in .NET..I guess that must be .NET 2.0+ ?? Is it as simple as just making the proxy class method calls and .NET under the covers takes care of the plumbing to actually send the request over Http unlike .NET 1.1 where you had to do all the plumbing yourself?
