View 5 RepliesI have an user control that reads the data from app_data folder and does some processing.In design time I'd like to show the row data in control placeholder (using GetDesignTimeHtml).To do that I need to figure out the absolute path to app_data folder on my project.The HttpContext is not available and HostingEnvironment.MapPath returns null.
View 3 RepliesI need to figure out though c# whether the OS is 32 bit or 64 bit.
Does IntPtr.size is the right way to figure out the version? 4 => 32 and 8=> 64
Does Environment.OSversion.version.major is right way? 5 => 32 and 6=> 64
OR should have to check both of them?
I'm looking at a site with horizontal menu and sub-items for each item. When an item is clicked, a second horizonal menu is presented under the first, with all the sub menu items for that particular main item. I can do this with the asp.net menu? Almost seems like it would require a second menu control under the first.
View 3 RepliesI have a page that has a note to the user about the file they're about to download and a button to click to start the download. When they click the button, it does a Response.Redirect to another page with the following code in its Page_Load:
Response.Clear()
Response.Buffer = True
Response.AppendHeader("Content-disposition", "attachment; filename=" & FileName)
Response.AppendHeader("Content-length", FileSize.ToString)
Response.ContentType = "application/download"
Response.WriteFile(Page.ResolveUrl(FilePath))
Response.Flush()
Response.End()
I want the download to start and then I want this page (which is a tab in the browser) to close.
The code to download the file works fine. I just can't figure out how to close this tab when it's finished. I understand that Response.End means that I can't put any more code this page; it will be ignored. But how do I get this tab to close?
I've been researching an issue for quiet some time, but most of the posts I'm reading are older. I'm trying to figure out if there is a new solution to getting an asp:dropdownlist vertical scrollbar. I have several dropdownlists with fixed widths, but the data that populates these dropdownlist do not fit inside the width. Is there a recent - acceptable workaround or solution? I'm using Visual Studion 2010.
View 4 RepliesI'm trying to create a simple contact form for a website and cannot figure out how to properly configure it. I have a simple code I got off a tutorial (VB), that I pasted inside my Contact.aspx code-behind-page:
[Code]....
It brings up errors everywhere (declarations expected, etc) in the code-behind-page. I'm new to VB so I don't know what I'm missing. The above code is exactly the content in my code-behind. Does anyone know what I'm missing?
Working with VB code - I have code which displays a figure between brackets. The figure displayed is a count of the amount of entries made to my textbox and outputs to my placeholder- I hope I make sense here...???Anyways, I'd like to output the correct data and time (at time of textbox entry) instead of the count.

I have a .NET app (webforms - .NET 3.5) that is running on a 64-bit server as 32-bit (I checked the IntPtr.Size result). The compilation is set to AnyCPU so I would expect that on a 64-bit machine, the app would be run at 64-bit. There are many Third-party programs incorporated into the app, could they be causing a problem? How do I figure out why 64-bit compilation is not being done?
View 1 RepliesI'm trying to figure out how to use SSL for only certain pages on my website. It's an ecommerce site, and I don't want the whole site to use SSL, only the checkout areas. I'm not sure what's needed to set this up, is it all IIS, web.config file, etc. I'm hosting with Discount ASP.Net, and will purcase an SSL cert through them for my site.
View 5 RepliesI have sesssion time out issue. Mine is a very big application and 10 yrs old application, so I m unable to figure it out. I have these timeouts in my web.config file. Session is getting expired in 2-3 min or sometimes I m unable to figure the exact time. Here is my timeout sessions in web.config file
<httpRuntime maxRequestLength="102400" executionTimeout="360"/>
<sessionState mode="StateServer" stateConnectionString=" something" cookieless="false" stateNetworkTimeout="30" timeout="30"/>
I'm passing a variable between pages and want to print the value of the variable on my page and don't particularly want to try to get into figuring out the codebehind stuff. I can't figure out the syntax. I'm trying:
Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication2.WebForm2" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<script runat="server">
Request.Querystring("letter")
</script>
I know I'm passing the variable correctly because it works in a query further down the page, so I suspect I'm just not using Querystring right.

tell me with code how to create it using asp.net server control in C#.
according to what i read from web there 3 types of custom server controls
1. composite
2.superclass
3.rendered
i found video tutorial to create and use superclass custom control in your project (extending dropdown control functionality)
i am trying to search video tutorial for other 2 types .
If a composite server control normally encapsulate styling information inside, it is an example of code encapsulation and modularization. However if css properties are included inside the composite control, it is not ideal for code/styling separation and css code re-use principles. Now which consideration should be the main consideration?

time for some expertise. I have a datalist which contains a radiobutton in the itemtemplate. This radiobutton is disabled (set enabled to false) by default.

However when the page is posted back. The checked property is always false.
I use the code below to retrieve the value of this rb:

This code is working fine when the initial state of the radiobuttons set to enabled server side.

View 2 RepliesI want to know: what are the basic differences between html server controls and web server control. As I have gone though lots of surfing but couldn't find the exact answer.
View 5 RepliesWhen a .NET server control is rendered in a browser it is rendered as a html control. Then how a browser differentiate between a server control and a html control. If the two control rendered as same then how server side events fire for a server control? If u say by using runat="server" attribute then also we can add runt="server" for html controls to work at server side... so then how these are recognized?
