Web Forms :: Image Color Change Dynamically On The Fly
Oct 11, 2010
I have created an aspx page that is displaying user profiles, and on that page I have an asp.net image control that I dynamically populate at runtime based on the users profile image.
I have created several themes, just modifying css to display the profiles with different background and different layouts.
For fun I have created one theme that is kind of like the matrix, and I would like to be able to take the users profile image and change it to a 'green scale' so to speak, or even just a straight up green color, more so this one #20f380. The profile images are just jpg, and are already cartoonish so they should change to green without the image looking to bad.
Is there a way to use code behind to change an image's colors?
C# or VB is fine, currently I've not been able to find any tutorials that work for me, or are close to what I am trying to do.
I have a report and in the body are a series of list to group the data. I can change text color no problem based on the value, but what I would like to do is change the Border Color based and values. I have gone to the Border color property and added an expression, but it does not alter the border color based on field values.
I have = iif(Fields!AmountOfContribution.Value < 70, "Green", "Red")
and regardless of the the vale in AmountOfContribtion it always gives me a green border.
If I put the same code in a text box of the list I do get the proper text.
In my website I have <img src from code behind (created the whole table and css in the code behind). So for an image I added as <img src='../combox/img/products/prod1.gif">
So when I run this page and see the view source, I get the following path for my image: <img src = "http://localweb1/combox/img/products/prod1.gif">. Here localweb1 is my development server.
But I want to change this "http://localweb1" to "http://www.mypage.com/ so the img src will show as <img src="http://aeroprod.com/combox/img/products/prod1.gif">
How should I do this in my code? Do I have to parse? In this case how do I do it?

I have a GridView with an alternating Css style. The GridView has a column called tradeId. What I want to show is an alternating colour based on a change in the tradeId. Is this possible? It will make it easier on the eye to group trades together by colour. Here's the GridView code as it is right now:
I'm trying to make a page, with a textbox, and a linkbutton. In the textbox you can enter any hex colour code you want, then you can click the linkbutton and the pages background will change to that colour. But I don't want the page to postback. I was trying this with themes, and then dynamically editing the CSS file. But neither has worked.
That's my CSS above. Unfortunately, the Menu text still shows the hyperlink-blue color instead of White. However, if I putForeColor="White", then it works. I'd rather not do that. I'd like to be able to set it with CSS. HTML below.
