i'm new to asp.net, but familiar with c#, .net. i want to write a cms for asp.net, which has the pages of the website in a database. these pages contain asp controls, like asp:Repeater which have to be processed after loading the page from the database, and before sending it to the client like a normal aspx page.
View 1 RepliesI need to know a way to process images in asp.net web pages. I need to be able to highlight a certain area of the image and put an image on top of the other, then save the image with those changes. So far everything I have seen requieres buy 3rd parties components which I can not afford, I need to develop this functionality using objects inside the .net framework, or a free component.
View 5 RepliesWorking on an ecommerce site which will be integrated with a 3rd party vendor--that vendor uses different identifiers for stores than we use internally (i.e. their store ABC123 is our 001-321). I'm researching the best approach to inspect incoming requests for reserved query-string parameters that indicate the request is using their identifiers and map the identifiers back to our identifiers (so if the request is example.com/&theirId=ABC123 I want to transform the request to example.com/&ourId=001-321). To do this mapping I need to inspect the provided ID, execute a lookup against the database or cache, and forward the request to the specified page--limiting the modifications to just the query-string parameters (other parameters will need to be maintained, as with the details of the HTTPHeader, etc). So far I'm researching a few different approaches: Implementing it in a base Page (which already does too much, but has the benefit of our Logging infrastructure and some other injected dependencies) Implementing it in an IHttpModule Using URL RewritingUsing URL Routing (looks like routing isn't what I want, feel free to offer insight if you think it still fits) Performance cost is a consideration: the actual number of times this translation will occur will be very small compared to the number of requests not requiring it--perhaps 1%. However for another integrated site we will perform this mapping on nearly every request--would a different approach be better suited to this scenario from the previous?
View 3 RepliesI have a requirement to show an Exit Popup on one of our processing pages. I am showing the exit popup by registering a client side javascript like
window.onbeforeunload = ShowExitPopUp();
The popup executes fine if you close the window, or try to type in a different URL. However the issue is that my processing page is also performing a "Response.Redirect" on the server side once the process completes. When response.redirect happens the exitpopup also shows up. Is there a way to have the exit popup not show up in that case?
Since my server side code is running through an UpdatePanel, so I have tried registering the following, in an attempt to remove ExitPopup from client side. However this doesn't work since server side redirection happens before end request.
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RemoveExitPopup);
We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?

View 1 RepliesSuppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?
I am reading in a file into a string. Then I am writing this string to a stream. I know this code works fine.
The only problem that I have is with the line that write the data in chunks where the parameters is not supported for the Write method.
The line that has the problem is this line. What do I need to change here?
OutPut.Write(buffer, 0, Math.Min(to_write, WRITE_CHUNK));

i am calling a function which is inside Homescroll.ascx.cs from Homescroll.ascx so i wrote on Homescroll.ascx as <% Response.Write(scroll()); %> but all this is in update panel,and i am getting errors. so is their any other way to call function from homescroll.ascx to homescroll.ascx.cs,instead of response.write();
View 3 RepliesI want to write a page where user's can write a blog post and publish it to the blog. I've downloaded blog engine .NET and looked at the code and I like the way they do it, but it's completely an overkill of what I need. What I need is only a title, author, date, and the blog post it self. I don't even want users to post comments or anything like that. My approach is to save all those blog post information into an xml and then when a page loads it loops around those xml files to show the blog post.
View 1 Repliesi'm developing a site using VS2010 and with my windows vista busniness OS. i used the default VS2010 wizard for new web application to create it. included a folder in the root directory and created new aspx pages to derive from the master page in the root directory of my site. everything shows on the new pages except the jpeg image logo in the master page. But other aspx pages i created in the root directory shows every thing fine.
View 1 RepliesPage B - loads slowly and needs to do some CPU-intensive operations on the web server.
I noticed that when someone is loading Page B, then Page A also loads slowly. This is even worse if multiple users are loading Page B at the same time. Page A won't finish loading until Page B is done.
Is there a best practice for making sure that Page A can still load quickly? Maybe a config setting or IIS setting that I need to change from its default? With 2 users loading Page B at the same time, the web server CPU usage only gets to 30% so I suspect it might be something I can tweak with the settings.
Currently I'm doing common functionality required throughout my site inside of my masterpage. What I want to do is move this functionality to a BaseClass so All my pages inherit from the Base Class. However, I'm not sure how to set this up interms of c# code with regards to Using a Base Class and then having a masterpage applied to my aspx pages that i create.
View 5 RepliesIn my Application_BeginRequest I have code that gets query string value ?c=FR or ?c=US and store it in cookies.Based on query string value I have either US or FR,locale is selected from locale table.If ?c=FR then locale will be fr-FR and if it is US then locale will be en-US.My code is below.
void Application_BeginRequest(object sender, EventArgs e)
{
LocalizationInfo loc = GetLocalizationInfo();
if (Request.Cookies["Localization"] == null)
Response.Cookies.Add(new HttpCookie("Localization"));
Response.Cookies["Localization"]["Country"] = loc.Country;
CultureInfo objCI = new CultureInfo(loc.Locale);
Thread.CurrentThread.CurrentCulture = objCI;
Thread.CurrentThread.CurrentUICulture = objCI;
}
public static LocalizationInfo GetLocalizationInfo()
{
string countryCode = "";
string sLocale = "";
if (HttpContext.Current.Response.Cookies["Localization"]["Country"] != null)
countryCode = HttpContext.Current.Response.Cookies["Localization"]["Country"];
if (!string.IsNullOrEmpty(HttpContext.Current.Request.QueryString["c"]))
countryCode = HttpContext.Current.Request.QueryString["c"];
if (countryCode == "")
countryCode = "US";
sLocale = HertzRent2Buy.DataProvider.ListData.GetLocale(countryCode);
LocalizationInfo ret = new LocalizationInfo();
ret.Country = countryCode;
ret.Locale = sLocale;
return ret;
}
public struct LocalizationInfo
{
public string Country;
public string Locale;
}
Now when I run the project and in query string I set [URL] then for the very first page(home page itself) it shows me French translation,but on subsequent page,that query string parameter ?c=FR is lost and hence it shows be English translation not French translation since it does not pickup French resx file.If I manually append ?c=FR in subsequent page then it shows the French translation.Is there is way how I can make that query stringparameter available in all pages.Structure is there to hold Country and locale variables. In all pages I am calling GetLocalizationInfo() method as follow
LocalizationInfo info = some.DataProvider.Globalization.GetLocalizationInfo();
And I create instance info to pass locale and country as parameter. GetProductDetails(id,info.Country,info.locale). why my query string parameters get lost on subsequent pages.

I have a few pages that are completely static. They only change at build time. But they are expensive to create. For the ones that are kind of expensive to create, I cache them for very long times using the ASP.NET output caching. But for one page, I really want it cached forever and ever or until the the next build.
What is the most expedient way to make this happen? Is there a build in feature that achieves this or a 3rd party tool?
(yeah, for the moment I plan to do the "view source" and copy paste thing, which isn't a very elegant build step)
I have added a jquey menu in my master page its working fine for those asp.net pages which are at the same level as master page.
But this menu isn't working at all for all of those page which aur in Editor's and Admin's folder. In these pages menu is displaying as simple html menu and unfortunately no jquery effect is shown on it.
I'm very confused why this menu isn't working for the pages which are in a seprate folder while the master page is added at the root level outside of all these folders.

How do you implement SquishIt to bundle Css/Js across View Pages and Render it in the Master page? I thought I could use a ContentPlaceHolder above the Render portion, but there seems to be some odd behavior where it sometimes adds 3 files (1 in the view page and 2 in the master page) but other times will ignore the file added from the View Page.
Index.aspx
<asp:Content ContentPlaceHolderID="CssFiles" runat="server">
<% CssHelper.Add("home.css"); %>
</asp:Content>
Site.master
<asp:ContentPlaceHolder ID="CssFiles" runat="server" />
<% CssHelper.Add("reset.css"); %>
<% CssHelper.Add("master.css"); %>
<%=CssHelper.Render() %>
My current solution is a Static wrapper around SquishIt's static Bundle class that keeps the BundleBuilder in HttpContext.Current.Items.
I'm curious if this has been done successfully and how so.
Is it possible with ASP.NET Master Pages to create content pages dynamically?That is, I know we can create content dynamically, but the content pages themselves,can those be created programmatically? I want to give my users the ability to define new content pages (i.e. Categories: Sofas, Tables, Lamps, and add/delete as they see fit) through a management panel. The resulting content pages should have proper URL naming, so that they index properly.An example: http://www.example.com/products/Lamps/contentpage.aspx.Is there a demonstration of this somewhere I can view?

I have a webpage that reads data from an external source. It can take awhile to retrieve the data.I was wondering if someone could give me an idea on the best way to have this happen in the background. I would like the page to come up and display 'Processing' (or somthing like that) in the panel where the data will eventually be displayed.I thought of the BackgroundWorker component, or maybe an AsyncPostBackTrigger... not sure if these will even solve the problem to my satisfaction.
