I'm using ASP.NET (not that it makes a difference I think), but when I click a button in one of the tabs, is there a way I can re-select that tab when the page reloads. I was thinking of sticking the tab section in an UpdatePanel. I was hoping there's a way I could trigger the tab to reselect.
I am having a problem in that a style is not being applied when I used an "ID" selector (#btnOK). However, if I use a class selector (.btnOK, by changing the "#btnOK" to a ".btnOK" in the CSS file), the style is applied.
The style IS also applied in design mode, but not at run time. It's findingf the css file, else, the class wouldn't be applied. Case sensitivity match on the ID.
More specifically, given a set of style sheets that define a class selector called "content_title", is there a way to apply that style to all <h1> tags without changing each one to <h1 class="content_title">, i.e. to effectively apply that class to all instances of a given element?
The context is that I'm trying to apply HTML and CSS from a graphic designer to existing web applications and some of the selectors don't match up very well.
I have an ASP.NET web forms application that uses master pages and a theme. I've been given an HTML sample/template that that includes several style sheets.
So I updated my master page to use the new design, and now it looks something like this:
<%@ Master Language="VB" AutoEventWireup="false" CodeBehind="MyMaster.master.vb" Inherits="MyApp.MyMaster" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <!-- these are the new style sheet from the graphic designer -->......
My goal is to use the designer's style without having to edit every content page that includes an <h1>.
I could copy the styles from the designer's CSS to the stylsheet in my app's Theme (substituting the class selector for the tag, of course), but then i wouldn't really be using the source CSS and I'd have to do this again the next time the external CSS changes.
I'm also not likely to get the external CSS changed to fit my app.
So is there something clever I can do to make <h1> == class="content_title" with respect to the application of styles, or will I have to bite the bullet and update each and every one of my content pages?
I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.
I would like to generate a static URL based on a few parameters.The page serve the file for downloading is called CertificateDownload.aspx ,I am generating the download link in Report.aspx.These 2 files reside on the same physical folder.I do not like the replace method ,but I could not think of another way of doing it.How can I improve my code or what is a better way of doing it.
I need the absolute url to be displayed as text in the web browser.
Dim downLoadUrl As String = HttpContext.Current.Request.Url.ToString.Replace("Report.aspx", "CertificateDownload.aspx") + "?CertificateID=" + CertificateName HyperLinkDownloadLink.Visible = True HyperLinkDownloadLink.Text = downLoadUrl HyperLinkDownloadLink.NavigateUrl = downLoadUrl

I have put a css file in App_Data folder and referrenced it properly in the page to be used. But when I browse the page then it does get loaded and page is shown without styling. Well I know why it is happening because Asp.Net run time blocks access to App_Data folder at run time. But I wanna ask that how we can make it working that is I put the css file in App_Data folder and it still works.
I have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = ""; static void OnClientConnected(string clientId, ref Dictionary<string, object> list) { list.Add("a", "b"); // I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:- BaseController.clientId = clientId; } public ActionResult Handler() { if (something) { // use the static ClientId here } // Release the ClientId here, so it can now be used by other web requests coming to the server. return View(); }
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
I want to access the static variable in my global.ashx file I am using classname.variable name for accessing the variable but the variable name dose not appear.Can someone tell me how to access static varialbe in *.ashx file.
TL;DR: Which is likely faster: accessing static local variable, accessing variable stored in HttpRuntime.Cache, or accessing variable stored in memcached?At work, we get about 200,000 page views/day. On our homepage, we display a promotion. This promotion is different for different users, based on their country of origin and language.
All the different promotions are defined in an XML file on each web server. We have 12 web servers all serving the same site with the same XML file. There are about 50 different promotion combinations based on country/language. We imagine we'll never have more than 200 or so (if ever) promotions (combinations) total.
The XML file may be changed at any time, out of release cycle. When it's changed, the new definitions of promotions should immediately change on the live site. Implementing the functionality for this requirement is the responsibility of another developer and I.
Originally, I wrote the code so that the contents of the XML file were parsed and then stored in a static member of a class. A FileSystemWatcher monitored changes to the file, and whenever the file was changed, the XML would be reloaded/reparsed and the static member would be updated with the new contents. Seemed like a solid, simple solution to keeping the in-memory dictionary of promotions current with the XML file. (Each server doing this indepedently with its local copy of the XML file; all XML files are the same and change at the same time.)
The other developer I was working holds a Sr. position and decided that this was no good. Instead, we should store all the promotions in each server's HttpContext.Current.Cache with a CacheDependency file dependency that automatically monitored file changes, expunging the cached promotions when the file changed. While I liked that we no longer had to use a FileSystemWatcher, I worried a little that grabbing the promotions from the volitile cache instead of a static class member would be less performant.
(Care to comment on this concern? I already gave up trying to advocate not switching to HttpRuntime.Cache.)
Later, after we began using HttpRuntime.Cache, we adopted memcached with Enyim as our .NET interface for other business problems (e.g. search results). When we did that, this Sr. Developer decided we should be using memcached instead of the HttpRuntime (HttpContext) Cache for storing promotions. Higher-ups said "yeah, sounds good", and gave him a dedicated server with memcached just for these promotions. Now he's currently implementing the changes to use memcached instead.
I'm skeptical that this is a good decision. Instead of staying in-process and grabbing this promotion data from the HttpRuntime.Cache, we're now opening a socket to a network memcached server and transmitting its value to our web server.This has to be less performant, right? Even if the cache is memcached. (I haven't had the chance to compile any performance metrics yet.)On top of that, he's going to have to engineer his own file dependency solution over memcached since it doesn't provide such a facility.
Wouldn't my original design be best? Does this strike you as overengineering? Is HttpRuntime.Cache caching or memcached caching even necessary?
Cant seem to get the following to find the 'skull' button when the 'heart' button is clicked. Here is the JQuery.
$(".voteup").click(function() { var id = $(this).attr("title"); var userID = $('[id$=HiddenFieldUserID]').val(); var ipAddress = $('[id$=HiddenFieldIPAddress]').val(); var skullButton = $(this).parent().siblings(".votedowntd").children("votedown"); registerUpVote("up", id, $(this), skullButton, userID, ipAddress); }); And the HTML... <table width="200px"> <td width="35px" class="votedowntd"> <img src='<%# (bool)Eval("skull") ? "images/skull.png" : "images/skull-bw.png" %>' alt="Vote Down" class="votedown" title='<%# Eval("entry.ID") %>' /> </td> <td width="130px" style="text-align: center;"> Num Votes Goes Here </td> <td width="35px" class="voteuptd"> <img src='<%# (bool)Eval("heart") ? "images/heart.png" : "images/heart-bw.png" %>' alt="Vote Up" class="voteup" title='<%# Eval("entry.ID") %>' /> </td> <tr> </tr> </table>
So basically what I need to do is when one img is clicked, I need to find the other one. Why is what I have not working? Is there a better way to do this?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim dr As DataRow Dim dt As New DataTable dt.Columns.Add("id") dr = dt.NewRow dr(0) = "23" dt.Rows.Add(dr) grvUsers.DataSource = dt grvUsers.DataBind() End Sub
I'm working on some basic form validation styles for an ASP.Net website. I need to select all span elements that are visible, and add a css style to another element. (Just to indicate which input fields are invalid.) The below code works like a charm in FF and Safari, but fails in IE. I've narrowed the problem down to the :visible selector. Here's the jQuery code. IMPORTANT NOTE: Production site is running jQuery 1.3.1 There were changes made to the :visible selector in 1.3.2 release notes
In some posts I have read on other forums, those with database connection problems (I am thinking about Access) sometimes get the error: 'Connection property has not been initialized' which might translate as 'you have not kick-started your connection'. One reason for that, according to a number of replies I have come across, is that 'you have not set the connection property of the command object' ('you have not told command how to connect').
So would something like this:
Code: Dim conn As New OleDbConnection Dim OleDbConnection As New OleDbConnection Dim cmd As New OleDbCommand conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|myDatabase.mdb;" conn.Open() cmd = New OleDbCommand("SELECT strName FROM school WHERE strName=@strName", conn) cmd.Parameters.AddWithValue("@strName", UserName.Text) cmd.Connection = conn cmd.ExecuteNonQuery() conn.Close()
a) initialise the connection property and b) set the connection property of the command object?
I have an ASP.NET page and I am trying to quickly match the validation controls that are tied to a particular textbox (text input) using a jQuery selector. The validation controls render as a span and the "controltovalidate" property renders as an expando property. Here is a test example:
The problem: the ml_test() function shows 1 in Internet Explorer 7 (as expected), but shows 0 in Firefox 3.6.8. I tried adding additional controls, but in Firefox it consistently doesn't work.
I discovered this post that shows the use of an ampersand in the selector like this [@expando=value], but when I try this syntax, jQuery 1.4.2 throws an error.
Is there a cross-browser way to select expando attributes, and if so, what is the proper syntax?
I am getting error ExecuteReader: Connection property has not been initialized. below is the code i am using.
