I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel:
[Code]....
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!

look at the picture, i want that image preview will come when i choose the file location before uploading to the database. is it possible?
EDIT: i found codes in other sites, they say those only work in IE, so it means currently, this preview function doesnt support FF? coz im using FF or sometimes google chrome.

I apply a watermark to an uploaded image.
After that I want to save the changes, but I am not able to delete the original file nor can I rename it because I get the following error.
The process cannot access the file because it is being used by another process.
I have already disposed all objects related to the "watermarking process".
It seems that the uploaded file is being locked by IIS for a period of time while I need to manipulate & save the file right after uploading.

Users of my C# web application can upload images. I have configured the max upload size in the web.config file to maxRequestLength="1024" and executionTimeout="180".
How can I check the upload size before uploading? (do you have examlpe or url?)
Another option might be to check the dimensions?...
Some web application allow the user to crop the image at client side. Do you have an example of this or url?

i am working on an ecommerce application, user will be uploading several images of a product, instead of stripping the size (i.e the KB or MB size) after uploading it on the server, i want to strip the size of image before uploading it to the server ( bringing the size from any thing over 30KB down to 30KB) i.e on the client machine itself and then upload it to the server. i understand that this requires a download on the client machine which makes me ask the following questions :
a. can i use a java control in dotnet since java control can be used on all OSes
b. is there any dotnet control that might be userfriendly to all OSes

Got a problem with regards to the file upload control on database updates. The problem is in my CMS, when a user tries to update content for a page it will add null to the fields containing the image path. What I need is for the system to check if the uploader has no image and if hasn't it has to do nothing. It can't add empty strings or null values as this will remove the original image path. Although they still need to be able to do image updates if the uploader has a file(this bits not a problem).
Here is a snipet of code to demonstrate what I'm trying to achieve.
