Whenever I sort a column and then edit a cell, after editing the column, the column autosorts so the recently edited cell is no longer in the viewable area. Is there any way to prevent this auto sort from happening and only sort when I click on the columns?

Opening An Image In Vb To Send Into A Database - Asp.Net

Apr 22, 2009

I'm currently patching an asp.net program where I need to be able to send an image to an SQL Server 2005 DB. It works fine when I use the asp:fileupload control, but the trick is that when the user deletes the image, I'm supposed to replace it with an image from the server saying "empty", in code-behind. I know how to open, use and save text files in vb, but I can't find any information anywhere on how to open an image / binary file in a similar manner so that I can use it as an sql-parameter on the update query. Below is an example of how easy it is to use a file from the fileupload control.
