I am looking for a control to display binary data as MemoryStream.
The binary source are converted from GIF, JPG, TIF, HTML image file and stored in a SQL table.
Please help.
If you'd like to retrieve the binary image from your database, and display it in your web page, you can create and use a generic http handler to fetch the binary data of the image file from the database and returned the image data through the response.

Hi,
You could use the img tag or the https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.webcontrols.image.imageurl?view=netframework-4.7.2 as usual. The two options are to give the location of an image handler to which you pass the image id. This handler then retrieve image data from the db and sent it back to the browser. You should really have tons of sample about how to do that. For example : https://www.developerfusion.com/code/5223/using-ashx-files-to-retrieve-db-images/
Another option is to use a https://en.wikipedia.org/wiki/Data_URI_scheme (likely best for small images that won't need caching).
