i am tring to connect to my db in sql server 2005 :) and have some problem with it.the error that i get is : Keyword not supported: 'datasource'.the line that i have an error is :
I have a control with a datagrid in it and I was wondering if depending on the value I get back from the a Request.QueryString if I could set the table name to that (that is the value being sent) and then have it build the columns?
I have about 3 different tables, and they have different amounts of columns, and of course with different names.
I am working on a financial portal and I am having a problem..I don;t know what to call it so i mentioned it as an 'unknown to me' problem..I have a webpage..whenever I click on any button on my webpage, the request goes through..but nothing show up on the webpage..then If I click on another link and then again come back to previous link,then only I see the results of button_click..
e.g.
I have a currency conversion and investment form..so after filling up the form in following way and if I click on "INVEST" then nothing shows up..
so now if i click on any other link and go back to 'buy currency' link I see the result as 'investment successful'
I have an ASP.NET website that worked fine using and debugging in VS2008. I went through the upgrade process opening the solution in VS2010. I can run the site, but as I make changes in the app_code folder classes, they don't seem to commpile and warn me of compile-time errors. As soon as I get to a point that calls the class, the errors show up. Sounds JIT I guess, but this isn't how it was working in 08. Is there an option that was changed in the upgrade process? This is a large project, I really don't want to break something and not find out until some obscure page is opened.
While 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.
Reponse results empty. This URL is a redirect to another page with query string, I already have a page that parses the query string and write the output to a page.But response is blank.
I am just wondering that, is there anyway to make an Ajax request using jquery ("$.ajax") and making partial rendering without using the .NET Ajax framework (without script manager).
I have tried this before, but it's executing the page_load every time and not reaching to the pagemethod.
I'm having difficulties to find a good explanation and tutorial on how to send an ajax request from one asp.net control (when clicking on an item in its )to update from the server another control.
Is UpdatePanel is the only solution- and does it really avoid a postback?
My 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.
I am in a situation where I need to get XML string of each product from server side on request, but only those tags that are added to XML at server side after the last client request. How can I determine at server side and return only newly added tags of XML of requested product to client so that only latest and relevant information could be shown at client side. And is there any way to save and keep on updating that XML data retrieved for each product on client side?
I'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.
This 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?
I tried the Request.IsAjaxRequest but this does not exist in WebForms. I am making a JQuery ajax call. How do I check if this is a ajax request or not in C#?
I am trying to send data to my code behind method. It works except when I add to the data param.
[code]....
UPDATE: After seeing what client side errors were being thrown it seems that the ID is undefined. Is my method of getting the elements ID incorrect? Keep in mind I am using jsTree and ca I possibly use (obj)?
Controller: Products and Action: Save, return a JsonResult. If a trapped exception occurs, i would like to signal that error to the client (ie:jQuery) with a custom error message. How can I do that both on the server and client? Can i utilize the function pointer error in this scenario?
for SEO purposes, instead of refreshing the page every click of a product, is it possible to click on the product and when the server comes back with the response, to change the URL of the page to reflect the new link to information currently on page?
point is to have ajax redraw the product details portion of the page but have SEO friendly url's displayed so if people want to bookmark the currently selected product, it will bookmark the right url instead of the generic one to access the products page..
For example... here's my entry point:
Products.aspx
product1product2product3 If I were to click product1, the request goes to the server with roducts.aspx?id=product1 but the url is still products.aspx on the response meaning that when people bookmark the product1 item, and they send the link to a friend, the friend always gets the generic product.aspx page.
I'm trying to get around this without refreshing the full page (postback).
