So I'm trying to make my own forum signature generator for some friends, and I've gotten most of the work done. My real issue now is refreshing the information when the image is requested from my server.
Basically, I'm looking for someone to push me in the right direction on how to have the image refresh from the datasource when it gets requested, but only if it has been more than 5 minutes to prevent an overload.
in asp.net how do i create a dynamic image control from code behind?
Dim image1 As Image
image1 = New Image
image1.ID = "image1"
image1.ImageUrl = "uploads/aa.png"
i have to add the control to the web page but how?
I need to create a very simple whiteboard with dynamic updates between connected users.

This is used to bind html elements in my view so if I need to make a modification to a Item contained in the list can I simply access this and post the VM back to the controller or do I need to post a Item object back to the controller in the singular. Secondly where is the best place to build a gui control such as a table. If in the view I have a foreach loop and write out table fields is this the most appropriate way of achieving this or should I deal with this in the Controller or Model and pass it to the gui in the View Model?

I'm no expert with Image controls, or dynamically adding anything, but I seem to have some problem when dynamically adding image controls
When the page loads the images are "there", but they don't actually show an image...just an image "box" I guess you could call it. It's not the "broken" image or "invalid" image display, but a friendlier one that doesn't make sense to me why it's there.
I look at the page's source and literally everything's fine, but I'm not sure what's going wrong. I can show you my code, and hopefully someone will point out the dumb thing I'm doing wrong:

So, it takes all the .JPG files in the folder "Pictures" of my project's folder and creates an Image control to be put into Panel1 with the ImageURL as its filename (with Directory Path) and even set the ID to its filename (so no duplicate IDs). Again, the source is exactly how it should be, but no image is shown.
I have a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events.
Clarification:
There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items?

View 3 RepliesI am making a page which will have to display the image of the user. Can I use the Image control to display dynamic images based on the user. Just like in gridview imagefield, we can have a different image in the columns but is it possible for the image control?.
I checked the properties of the controll and I think all I can use is the "ImageUrl" property which selects a fixed image.

Dynamic image button does not work
I am adding a set of images on Page_Init, and on some button click I want to update those images. For some reason it doesn't work. why?
This is my code:
[Code]....
I can see that ButtonSubmit finds the correct control and changes its property, but on the response to the client I still see the old image.
I have a situation where I have ~10-20 different background images in a folder. When my site loads I need to choose a specific one of these images based upon some values from the database.
I thought about using runat=server on the body tag, and then adding the attributes dynamically on page_load.
How would one do this "the right way" ?
