I want to change some elements text when page is leaving the server (page_render, endRequest etc.).
How can i get access to the page and how can i find the elements to change their values, texts?
I've got the following Setup in my Theme:
App_ThemesDefaultStyleSheet.css
App_ThemesDefaultPrintStyleSheet.css
The PrintStyleSheet.css file has a set of printing css rules set in them wrapped in an @Media Print { } block.
I need a way to programmatically remove the PrintStyleSheet.css from the list of css files for ASP.NET to inject based on some flags. (Some instances we want to print the site verbatim without custom formatting).
I know i could build a seperate theme without the PrintStyleSheet.css in it and switch the theme programmatically, however this would introduce duplication of my master stylesheet which is not acceptable.

I have a aspx page which contains 6 user controls which will be displayed when the user clicks on any button using show model pop up extender. My page rendering takes more time. it taked 3 minuits to load the page. If i debug the page its traveling to page load of all the user controls. Its not taking more time to fetch the data from database but its taking time to load the page. Is there any way to improve the perfomace .Is there any place where i have to look into.I am using VS 2010 and c# .
View 2 RepliesI have an ASPX page that I intend to use as a template to generate some HTML. I have defined my markup and data bound controls and built a function to do all the data binding, call this.Render and return the HTML. The function works just fine when called from Page_Load.
My intent was to bypass page request and directly call the method and get the page HTML, but when I call the function without making a HTTP Request, none of my server side controls are initialized.
Is there any way I can call a method on a page, pass some params and get the HTML output without making a HTTP Request. I believe Server.Execute could do it but i cant find a way to pass params in it.
I am calling the function like this
MyPage ThreadHTMLGenerator = new MyPage;
string threadHTML= ThreadHTMLGenerator.GenerateExpandedHTML(param1, param2, param3);
What is the best way to build a progress page? In short, I want a user to complete a series of "setup steps" and hit a "Start" button. I would like them to be immediately redirected to a "Progress" page that will show them the progress of each step. In my case these would be: Shutdown device, copy file, Start device.
My approach so far is to build a Progress View page and use partial views. Here is what I have so far. I would like the Progress page to show up right away even if the ShutdownStatus View has not finished rendering. At some point, I plan on including a progress bar but right now I'm just curious as to how I can show the Progress page immediately then show each partial View as it completes.

I have an aspx page that on a button click creates a BackgroundWorker and then calls the RunWorkerAsync method. In my aspx file I have set Async='true' but when I run the application and click the button it appears as though the page waits to refresh until the processing of the BackgroundWorker is done. How do I get control to return to the page (and have the page refresh) after the BackgroundWorker is created and started?
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += RunJob;
worker.RunWorkerCompleted += JobCompleted;
worker.RunWorkerAsync();
I am using a table and within the table i have gridview and textbox controls. On the rowcommand i am populating the data in text boxes.

I am trying to display reporting service elements in a web page as little 'widget' like elements, where when you click on one of the elements it takes you to the reporting services page that holds all of the data.
This works on my machine, and when run on two other machines, however, it is not working on the development server or another developer's machine.
It works in dev in Google chrome, but not in IE 7 or 8. The images/links work if you right click on them and select "open link", but they are not click-able as links, which pisses the business unit off.
I would really appreciate some help on this. Here is the information pertinent to what I am trying to do. URLs and such changed for obvious purposes.
.NET 3.5
= IIS 7
This is the ASPX element as added on the page.
<div style="width: 411px; float: left;">
<a href="RenderReport.aspx/myreport.pdf" style="text-decoration: none;">
<rsweb:ReportViewer ID="rptVwOriginatedFallout" runat="server" Font-Names="Verdana"
Font-Size="8pt" InteractiveDeviceInfos="(Collection)" ProcessingMode="Remote"
WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" ShowToolBar="False"
Height="260px" SizeToReportContent="True" BorderStyle="None">
<ServerReport ReportPath="/MyReport" ReportServerUrl="http://reportingserver/" />
</rsweb:ReportViewer>
</a>
</div>
At the top of the page I have:
<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
In the web.config under assemblies I have:
<add assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
<add assembly="Microsoft.ReportViewer.Common, Version=10.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
Under the httpHandlers I have:
<add path="Reserved.ReportViewerWebControl.axd" verb="*" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false" />
I have tried placing the appropriate information under and running it in Integrated mode as well on the server, but that did not work either.
I need to save some information about user (some kind of statististics) on post back. But saving takes time and I don't want user to wait for this process. User does't need to know about that saving process.I'm thinking of using ThreadPool or Threads. I want page to be rendered right after I put saving function to the threadPool, not after saving was done.
View 3 Replies I know i could possibly just throw and exception and let the server handle the interruption but for personal knowledge and exploration, i would like to do it more than having the server automate it for me. I hav built a shared method that will take in information such as:
[Code]....
During the body, it just formats a series of information into a table and i would like to add the table to the page. Now i know you just simply do "Page.Controls.Add(Object)" to add the table to the page. Problem is that it adds it to the bottom of the page after rendering all the other content.
I would like for this method to interrupt the rendering process, clear out what has been built up and then output the table to the substitute the page pre-defined content.Very similar to what IIS spits out when it encounters and error and show the Exception name, message, and stack-trace. Although my exception is by no means that complicated.
I have an aspx web page that renders correctly. When converted to razor, it does not. Here is a simplified example (stripped of all extraneous stuff).
aspx:
<asp:Content ID="indexContent" ContentPlaceHolderID="ToolContent" runat="server">
<% string test = "<div><b>Tag Test</b></div>"; %>
<h2><%= test %></h2>
</asp:Content>
razor:
@section ToolContent {
@{ string test = "<div><b>Tag Test</b></div>"; }
<h2>@test</h2>
}
The aspx renders as expected. The razor just displays the content of "test" (<div><b>Tag Test</b></div>) in the header tag.
I assume that my understanding of razor is flawed. If someone could enlighten me and/or show me a solution/work around.
I am working with a pretty complicated .aspx page that is full of controls (Telerik, Ajax, etc.) that all expand, collapse, show, hide, etc. when the page is loaded. Since this rendering happens on the client-side and can take different lengths of time based on the users machine specs, is there a way to detect when all (or some) rendering has taken place (jQuery?) so I can then act on specific elements, knowing they are fully rendered?

I need both show the cshtml page,and persist it to a file for next visit.
first I found Response.OutputStream, but it was unreadable.
then I found in asp.net we could override Page's Render method to achieve it,but I don't know in webmatrix how to do it.
and in MVC we could use ActionFilter, but I really don't find how to achieve it in webmatrix.
I have several datalist controls inside a panel control.
When I do a databind on the "movie" datalist, data is populated. I can see during the debugging on the aspx page that it goes into the label controls and binds the data.
When I do a databind on the "alacarte" datalist, the data isn't populated even though before doing the databind I validate that there is a record inside the generic collection that I use for each separate type of datalist. When the databind occurs, it goes thru the alacarte datalist and does the databinding to the fields, but when the page renders, it doesn't produce any output inside this datalist.
The code behind below is the databinding for the movie datalist.
DataList grdMovies = ShoppingCart1.FindControl("grdMovies") as DataList;
grdMovies.DataSource = lstMovies;
grdMovies.DataBind();
The code behind below is the databinding for the alacarte datalist. I verified that there is a record inside the lstAlacarte collection with the same field names that are in the html for the alacarte section during the databinding.
DataList grdCartAlaCartePgming = ShoppingCart1.FindControl("grdCartAlacartePgming") as DataList;
grdCartAlaCartePgming.DataSource = lstAlacarte;
grdCartAlaCartePgming.DataBind();
Below is the html on the aspx page for the above controls. I included all of the html so as to see if there is anything I'm doing wrong. I even placed the words "desc" and "price" to see if that would render and it did not.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ShoppingCart.ascx.cs"
Inherits="DishRedesignClient.ShoppingCart" %>

When Bing map control loads for first time on any browser all pushpin on map are visible.
Bing map control renders perfectly.
Then I refresh browser it create rendering issue some custom pushpin on map gets disappeared. This behavior continues with pushpin. Pushpin are (.png) images and I am not using default bing map thumbtacks.
May be it is issue of browser caching content or Bing map control rendering issues on various browsers.

I am currently developing a site in the .Net Framework 3.5. The site works correctly except when the user selects the Compatabilty view. I am unsure of how to make the page render properly in compatabilty mode. I have problems with the repeater displaying data correctly from the sql Server. I also have a dynamic menu that is called from the server this too also renders incorrectly in compatability mode. I am a new asp.net developer and I havent come across this type of problem before. Basically I want the site to be correctly viewable in IE 7 and 6.
View 2 RepliesI have to create facebook style wall in my project. So far I assume that I will get X(the number that needs to be shown be default) number of wall posts from database, bind them to some control like Repeater and add update panel in each row in repeater so that only the portion of page only related to that post is updated once any new comment is added in that post.
Now, since I am new to AJAX so cant figure out how to display the "older post" link functionality there. As we have link at the bottom of facebook wall which once clicked appends the certain number of older posts at the end of the wall.
Similarly, once a new post is added by someone, it gets added at the top of the wall, how can I acheive that so tha only the limited portion at the top of the wall gets refersed and updated instead of whole page post back.
have a situation very similar to the one in this question:http://stackoverflow.com/questions/774695/selective-cache-clearing-across-load-balanced-servers-asp-netThe difference is that due to our hosting configuration, I am unable to address individual servers by IP address. Assuming I cannot access specific servers via web requests, is it possible to access the HttpContext of a web application running on the same machine? I'm thinking I could accomplish this with a windows service that I could address by machine name, or alternately a console application
