I'm writing a script and need with being able to modify the ImageUrl property in a HyperLink control from the code behind page. It is meant to dynamically show an image.
I just need to know the correct format of the code behind to get this to work.
Is it possible to specificy height and width dimensions of the ImageUrl attribute in a <asp:HyperLink> control? I tried setting the height and width attributes of the HyperLink control thinking the picture specified in the ImageUrl attribute of the HyperLink control would be resized to the dimensions of the height and width attributes but it wasn't.If I can't somehow resize the specified image for the HyperLink Im gonna have to scrap the control and do it the old fasioned way. By using a regular <asp:Image> control inside an <a href>.

I am realitivly new to c# and I am trying to do something that is probably simple, but I might just be over thinking it.What I want to do is have an image change based on a return of a sql data call. I am using a stored procedure that reads values and uses a case to switch between red, yellow, green for status. For example, I have nine items that the SP goes through and returns one of the colors. What I would need is if it detects a red, change the image to red and so forth. Now, when I execute the SP in C# I can get the data but it always just reads the last value. So if it had a red in there and the next one is a green, it uses the green. I even thought about reading the colors and using an IF statement adding the values to determine which color should be used.

I've got a SQL Server database with a table in it, which lists the file names of images. It's my intention to assign the ImageUrl of an Image control on the page, from the data in the table. I've placed a SQLDataSource control on the page, and then tried putting a FormView control there, and an Image control within that. But I don't see how I can assign the value to the ImageUrl property via data binding.

I've basically got 2 applications. One is my back office application (Admin) and the other , the front end application (web site)
My problem is that, the admin uploads 'n' number of photos ,which is stored in one of the folders within my back office application and the path is stored in my DB as , for example : ~/Uploads/test.jpg.
But it is not possible for me to access this image from my front end application because the path actually exists in my back office app. How do i get to view the images that I uploaded on my front end Appn. ?
I have an Image control with the ImageUrl property set to point to an image on a network folder, the address looks like this:
\fs01PRODUCTSimagesAM101.jpg
It renders correctly in IE but not in Firefox.
pasting the url/path directly into the browser, the address is maintained in IE: \fs01PRODUCTSimagesAM101.jpg
But in Firefox, it is converted to this: file://///fs01/PRODUCTS/images/AM101.jpg
I suspect this is related to the problem.

We have a database with around 5000 records in it. We also have a web page that displays many of the fields. One field is an nText field and displays up to several paragraphs. My customer wants me to add those A+ and A- buttons for increasing and decreasing the font size for this field. My problem is that many of the older records have quite a bit of formatting in the field. Most of the rest contain styles dictating a font size of 12 px. Is there a way to increase and decrease the font soze of the text without modifying all the records?
Here's an example:
