I'm working on an ASP.NET MVC project and I've come to the point where I want to start considering my caching strategy. I've tried to leave my framework as open as possible for the use in caching. From what I heard during Scott Hanselman's podcast StackOverflow.com uses page output caching and zips that content and puts it into RAM. T...
I can't seem to figure out why this does not work below. I need to bind the text box to a value from an inline expression. Seems like a simple thing right? But neither of these work. Any ideas? Thanks in advance. <asp:textbox id="tbName" runat="server" Text='<%# Eval("test") %>' /> <asp:textbox id="tbName" runat="server" Text='<%= "test...

One of my applications uses sql session state, the timeout is currently set to 20 minutes. My question is, since this is stored in the database and not in server memory, I should be able to increase the timeout without any significant performance issues right? I dont really understand the importance of the timeout for the database sess...

Folks, I am having a devil of a time with a custom control. The control is very simple - it just displays a list of "StepItems" (rendered as table rows), each with an icon. When I first drag it onto a page, and add StepItems to its collection, it renders perfectly. If I provide some text for its Header property, that also renders per...
I have three radio buttons on a form - A, B, C. Each of these selections populates a dropdown list with data specific to the option. When the form loads, I set option A to be checked (as the default). When I select buttons B or C, the AsyncPostBack triggers fine and the dropdown is populated. BUT, subsequently selecting A from either B...

Lets say I bind 25+ images to the repeater and I want 5 images per div. How do I go about conditionally creating the start and close tags for the div? Is this a...

Currently developing an ASP.NET WebApplication with VS2008. I stopped development for a few weeks, and when I came back, my project is exhibiting the following problem: The whole project compiles fine (all targeted to Framework3.5SP1).

Hi! I need a way to read a Excel file from a stream. It doesn't seem to work with the ADO.NET way of doing things. The scenario is that a user uploads a file through a FileUpload and i need to read some values from the file and import to a database.

On top of page ad On Error Resume Next After each line of code use If Err.Number <> 0 Then Response.Write Err.Description Err.Clear End if...
Hi, If you distribute a .net web application, and you want a certain module of the application to be disabled, AND you don't want to ship the source with it, is it a reasonable solution to just not include the necessary .dll for that module? I know you can do things programatically, but as long as you don't ship the .dll things should ...

The caching is custom depending on the logged in user. The chart data is being lost while the control is cached. I see the chart one every 30 seconds but at no point inbetween. Am I missing s...

My question is fairly generic and I know there might not be an 100% answer to it. I'm building an ASP .NET web solution that will include a lot of pictures and hopefully a fair amount of traffic. I do really want to achieve performance. Should I save the pictures in the Database or on the File system? And regardless the answer I'm more ...
