View 4 RepliesI have this in my code-behind file (VB.NET):
[Code]....
Here is the HTML source of the part of the page:

Where that comment in the code-behind file says "REFERENCE IN CODE HERE", that is where I want to set the value of the "remLen3" input (client-side control) to "30 characters left."I obviously left out irrelevant things like inserting the txtNewComment.Text into the database. But what's going on here is when the user types in something into the txtNewComment text box, I'm using javascript to change the value of the remLen3 control.My problem is that when I submit the text from the txtNewComment textbox to the database and set the txtNewComment.Text equal to Nothing, I don't know how to reset the remLen3 field value back to saying "30 characters left.". I already tried to add a "runat="server"tag to it, but when typing stuff into my txtNewComment textbox it gives me an error. I already tried to figure out what the error meant, so I'm not going to spend time trying to solve it anymore; I would rather just see if there is a workaround to using the runat="server" tag. Maybe do some kind of a CType(FETCH_REM_LEM3_HERE_SOMEHOW, INPUT_TEXT_TYPE??).value = "30 characters left". If there is a way of converting the input text control (remLen3) that way, then how would that be done? I just want to change the value of that field when the server-side button is pushed.
I have been given by a designer the HTML show below. This is a menu which will be used in throughout our website in a master page. My worry is how can I handle de the different class used depending when the page is selected or not. Below when on the page the id is "bot_seleccionado" and when a page is not selected it is bot1.

We have recently bought a website that was programed in .asp. Every website page has a line of code that allows it to use the Meta title tag found in the 'Maincontent.master' file.
This sample is taken for the about us page;
<%@ Page Title="" Language="C#" MasterPageFile="~/MainContent.Master" AutoEventWireup="true" CodeFile="AboutUs.aspx.cs" Inherits="AboutUs" %>
I want to each page to have its own unique title tag, however I am struggling to implement this. I have tried removing the above line and replacing it with a standard title tag line i.e. <title>About us</title> but when I do this it kills the page completely. how I could replace the above with a unique title tag, or is it not that simple? Descriptions and keywords are not a problem as they are already individually setup; it's just the page title
I am using Visual Studio 2008, .NET version 3.5, and coding in C#.In my masterpage, I have a div:
<div runat="server" id="divMasthead" class="top-img">
In the code behind of that masterpage, I am trying to randomize which background image displays for this div on page load.When I run my project, the div has no background image.After opening the site and viewing the page source, the html output is:
[Code]....
I have a height on this <div> that I have set to 104%.
Now I am trying to dynamically change this height in the code behind to different % like below example, 110% but the divs height is not changing.
I wonder if I do this wrong ?

I have a XSD file in my website. I need to give its path in code.
using (XmlTextReader textReader = new XmlTextReader
(@"C:VS2008ProjectsInterfaceSchema.xsd"))
But, If my website move to dev server, QA server, Prod server, I need to change the path here. Can we do any other way instaed of whole path. Like example for css file, we just name of <link href="filen.css">.
I tried to replace the path with "/Schema.xsd" but getting exception file not found. I tried eith ~ root symbol also. No use.
I also can do by keeping the value in webconfig. Even though, i need to change it every time.
I have a application, and I want to log exceptions to a file and I don't want to change any code. I just want a component to which I can add my code and it will start logging exceptions. How can I do this?
View 3 RepliesOn the MSDN page for the Membership.ApplicationName property (which applies to an asp.net membership provider), it warns that although one can change Membership.ApplicationName in code, 'The ApplicationName property is not thread safe for multiple writes, and changing the ApplicationName property value can result in unexpected behavior for multiple users of an application.' They therefore recommend avoiding using it for a 'web application'.
This is because the default SqlMembershipProvider is written as a singleton. But here's my question: is it OK if all the threads in my application process are going to set Membership.ApplicationName to the same thing?
I'm thinking of having multiple applications on my IIS box, each with their own separate application pool. I want to point them to the same location, but based on the hostname, set the application provider to different things. Wouldn't this actually be OK? It might not be a thread-safe operation, but doesn't each application pool have its own process and therefore its own instance of SqlMembershipProvider? So, every thread that tried to set Membership.ApplicationName for a given SqlMembershipProvider instance would be trying to set it to the same thing (the provider that is appropriate for that hostname).
What I need to do is perform some kind of decision statement and when true I need to change the backcolor of a treenode to grey, so that it has a grey box around the whole text. There is no backcolor property for the tree node and I don't need it applied all the time so I don't think a CSS class will do this.

View 2 RepliesI have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.

I am working solo on an Asp.net/C# project created by someone in the past. I created two new web forms, and then built the prjocect and did the deploy using a TFS team build project. For some strange reason, my Aspx file is not getting copied to the destination DEV server. It does get copied to a temp folder on that server, but in the end, the team build is failing and not copying over the new Aspx file.
So until I figure out how to fix the team build script, is their a way to just copy the Aspx file out to the desired server location? That as well as copying out a dll which is associated with the build file?
I have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?

On a typical form you have some fields and submit button. What event do I use to retrieve the values of the form from the post , process the forms submit?
How can I add page events to the code behind file (.cs file)?

View 1 RepliesI have a ASP.net which allows users to select a number of inputs and dropdown lists to filter the report and to download an Excel report after pressing a button on that same form.
The page can be used mulitple times, by changing the inputs and pressing the download button each time.
The button should be posting back to the hidden IFRAME to a separate webpage, but I am unable to change the target for the form on the fly as needed.
<form runat="server" method="post">
<asp:Button runat="server" id="DownloadToExcel" TabIndex="-1" Text="Download To Excel" UseSubmitBehavior="False" PostBackUrl="report.aspx" />
</form>
<iframe style="hide" id="output" src=""></iframe>
Additonally, when I download the file when pressing the "DownloadToExcel" button, the file downlodads as expected. However, any additional postbacks including updating the screen are posting back to report.aspx and not filter.aspx.
How do I correct the postback so it only postbacks once to download the file, and then change it back to the original page so the screen can continue to be used to filter and download a second report.
This may also eliminate the need of the IFRAME as well.
Is it ok to change the config file after publishing a site? I use shared hosting. It would be nice to do things like change connection strings and smtp settings with out having to republish the site.
