Recently I came across a problem with an Image Button in an ASP.Net application.
The image file was replaced with the same name in the server when user uploads a new Image,but The image button still showed the old Image even after the page was refreshed.
Did Overcome this issue by adding a query string to the ImageButtom url
Image1.ImageUrl="images/ID102.jpg?"+DateTime.Now.ToString("ddmmyy");
Would like to know if this is the only solution to this??
You should include hours, minutes and seconds to resolve caching problem (also you can add random number but not current datetime))
Your browser was likely caching the old image since it had the same url.
Refresh the page with ctrl+f5 or open up your developer tools and turn off caching in the options.
You can also detect caching by hitting F12 in your browser and looking at the network tab and watching the requests. If you see a "304 Not Modified" it means it's using a cached version.
I always use Google Chrome's Incognito mode to discard any stored cookies/cache while testing my apps.
