Web Forms :: Changing Div Backgfound Image In C# Code Behind
Dec 3, 2010
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:
Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.

in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!

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;
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

Environment: IE7, ASP.NET 3.5 SP1, C#, IIS 7, intranet, SQL server 2008 R2 enterprise. I'm trying to implement a page with 3 pictures in it (each picture is up to 1MB, jpg format), and switch them with the next 3 each 250 milliseconds. I thought of several methods for implementation:
1. Store all the pictures in a virtual folder, then switching the src attribute of img html element by javascript, and manipulate caching by storing the next 9 pictures also as img element, but with display:none for css.
2. Store the images in a database table and than send it to the client using DIME (don't know how to do it yet).
3. Store the images in a database table and use custom http handler to retrieve the picture (don't know how to do it yet).
4. Client invocation of webservice? Which of the above results the best performance? Is there another method for caching pictures?
