Dynamically Get Images From A Database And Set It To CSS Background?
Nov 8, 2010
This is something I just couldn't figure out how to do in ASP.NET:
I have a database of photographs, with upload/management and all that.
What I want to do is to dynamically change/create a css file that changes the background of a div to one of the selected images on the database. (bing.com style).
Is this possible using images stored directly on the database? (sql2008) Or maybe possible only using uploading images to a directory and saving it's path/name on database?

I have a website using Telerik controls for ASP.NET. When an AJAX request starts, the Loading Panel (defined in the master page) will display, with a loading image, text, and faded white background color. It works totally fine in Firefox and Chrome, but the background image and text don't display in IE8. All that displays is the white background.LoadingPanel code: Loading ideas why IE8 isn't displaying the images? I've inspected the page source, and they're there in the CSS.
I have a master page and I need to give user a option of selecting color like red , blue or green. Once it selected the Background color of an image should be changed from transparent to selected color. How to do it?
I have a new control in which I have successfuly embedded some javascript to the assembly as a WebResource as well as a CSS file which has background images.

I want to dynamically change the color of the web page based on the day of the month. I'll hard code the colors for the 1st, 2nd, etc., but I need to test for the date and choose the color.
I can change the color of the return value based on conditional statements but cannot figure out the correct syntax to change the table cell back ground. My attempt is commented out.
How do I correctly declare the table cell? Findcontrol must not be the correct way.
i have n ASP .net page containing a HTML-control Table (LoginTable) with a background image, i want to change the background image. the Asp page has have a masterpage also. the code i am using is,
Now i am saving the country of the user in Session["Country"] variable , also i am using two labels and two textboxes , initially the labels text is ABN and other Label text is ACN , and initially the Textbox length against ABN Label is 14 and and ACN Label is also 14 , now i want that whenever the Session["Country"] changes to Pakistan , it must read the configurations of Pakistan node in xml file and set the ABN Label text to NTN and the textbox which is after it must allow 18 numeric digits only instead of 14 numeric digits , same for ACN Label change to BCN and textbox which is after it must allow 22 numeric digits only instead of 14 numeric digits
I have a grid view that displays some diary data that consists of a date, a diary entry and a diary entry type (eg holiday, info, meeting..)How can I change the background colour of a row depending on the diary entry type.So for example if the type is 'holiday' colour the row yellow, if its 'meeting' colour it red etc etc
I am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code):
DynamicString = FunctionThatCreatesDynamicString() ' DynamicString = "[URL] If ImageExists(DyanmicString) = StatusCode.200 Then ' Embed link in ASP.NET page Else ' Embed not found image in ASP.NET page End If
My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML.
I'm using a lovely jQuery plugin to load static images into a thumbnail viewer - the locations are hard coded which doesn't serve us any use other than for a demo.
I've managed to pull the images from our server into a unique folder but I've no idea how to load the images dynamically to the plug in. This is the format for the images in the plug in.
[Code]....
The documentation says I can use a JSON array too:
[Code]....
But I don't know how to make this "dynamic". I have the filenames and folder location in C# in my code behind - no idea how to pass this to the jQuery plugin. I can collect the file names and pass to a new ASP page (ie no need to load from the current page).
I'm fairly new to ASP.NET but I have developed quite a few WinForms apps in C# where I've used the System.Drawing.Bitmap namespace extensively without much issues.
Today, I decided to write some code to dynamically create some PNGs on the fly in my Page_Load event and everything seems to work fine. But I notice this scary looking warning on the microsoft documentaion site. What is up with that ??
I am unaware of any other ways to deal with images in .Net except using System.Drawing.Bitmap ...
I want to create a page that will dynamically change the images displayed, based on which link the user clicked to get there. For example I have different movies listed and when you click a link for one of them it displays all the images for that movie. I need it to be on one page because at the moment I have hundreds of pages and its very hard to manage. I have the images stored in BLOBS on SQL Server 2005. I can retrieve all the images for a certain category and store the Image data for each one into a list of images. What I cant do, is display the images on the page. I can display one image by using the queryString to get the image by ID, then putting the Eval code into an asp:image, but I dont know how to do it for multiple images.
