ASP.NET CSS file not loaded when adding HttpModule to web.config

阅读更多关于 ASP.NET CSS file not loaded when adding HttpModule to web.config

i am making a Website with c# and ASP.NET 3.5, i just made an HttpModule to handle the NHibernate Session Life (Open and close). I added it to the web.config and everything works fine. (all the query, code, etc working fine) except that CSS file of my masterpage is not loading !! it's so strange for me, Do you have any idea what is the cause of this behavior ? Thank You all, at last i found the solution, the problem source is working with the session in the HttpModule events cause strange problems. It looks like it is a known issue and whether or not session state is available is actually

ASP.NET Membership Issues With Registration

阅读更多关于 ASP.NET Membership Issues With Registration

I'm having a rough time with this membership stuff. OK, so, it's really odd. I can register a user. I can register, I can login. However, when I go to register ANOTHER user the user isn't saved in the database and I get a Membership credential verification failed event when the user tries to login (I assume because the user is never being saved). Here is the code I am using to save a new user. On the page: protected void btnRegister_Click(object sender, EventArgs e) { if (false == ValidatePage()) return; FormsAuthentication.SignOut(); MembershipCreateStatus status; Data.User user = UserManager

jQuery AJAX response always returns nothing

阅读更多关于 jQuery AJAX response always returns nothing

The following code returns a blank response no matter whether or not the Function exists, or even the Web Service file entirely: $.ajax({ url: "/ws.asmx/HelloWorld" , type: "POST" , contentType: 'application/json; charset=utf-8' , data: '{ FileName: "' + filename + '" }' , dataType: 'json' , success: function (data) { } }); Why is this? Also, might be worth noting, $.load() works fine! Your error is that you try to construct JSON data manually and do this in the wrong way: '{ FileName: "' + filename + '" }' You should fix the code at least to the following '{ "FileName": "' + filename + '" }'

Need workaround for .Net Master Page Name Mangling

阅读更多关于 Need workaround for .Net Master Page Name Mangling

I'm evaluating converting an old frameset based asp.net website to use master pages. The only thing holding me back is the huge amount of work it will take to update every page to deal with name mangling. Most of my problems are with javascript referencing hardcoded Id's. Is there a way for me to tell ASP.Net that for a particular content area that I don't want mangling to occur. Leave it to me deal with name conflicts. Note I'm aware .Net 4.0 has a solution for this as detailed here . I want a solution that doesn't involve waiting, needs to be .Net 3.5. Update Any suggestions for opensource

Server returns blank pages with asp.net 3.5 on IIS6

I have a problem with site deployed on IIS6 sever. Here the problem, when I first deploy asp.net 3.5 site to server (site is relatively small with 5 pages and 5 libraries in bin), it is works as expected. But after some period of time (~1h) server returns black pages instead of expected content: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=utf-8"></HEAD> <BODY></BODY></HTML> First my idea was that my site conflicts with other .net 2.0 sites that hosted in the same server, so I put my site into dedicated

Prevent double-clicking on Button

阅读更多关于 Prevent double-clicking on Button

I keep having an issue with users double-clicking on action buttons on my web application, which is meaning duplicate records are being added into my database, and sometimes the user is being charged twice (as the action is being ran twice). What is the best way of preventing double clicking in ASP.NET? I see you're concerned about this in the face of users without javascript enabled. If that's the case, you need to deal with it on the server side. One idea to deal with this would be to implement CSRF tokens throughout your app. This basically keeps a token in the server side session, and also

Stop postback on TextChanged

阅读更多关于 Stop postback on TextChanged

I have a textbox in an aspx page that has a TextChanged event attached to it. I also have a validator attached to the textbox. When the text is changed, the validate triggers but in case there is an error the textchanged event is still called. Do you know if it's possible to stop the postback on textchanged if the validator fires? <asp:TextBox ID="txtQuantity" runat="server" AutoPostBack="true" ontextchanged="txtQuantity_TextChanged"></asp:TextBox> <asp:RequiredFieldValidator ID="reqQuantity" ControlToValidate="txtQuantity" runat="server" ErrorMessage="The quantity is mandatory."></asp
