I have a fully working app using the original upload control. I add a reference to this new dll, but I can't see any new controls in the toolbar. Am I doing something wrong? I can't find clear instructions on how to install this.

What my program needs to do is this: Let the user select an excel file to upload. When he clicks "Upload", the file is uploaded, and the contents are displayed on the left in a table (including the cell color information). Then the program processes the information row by row, and then finallly displays the results in another table on the right. The file is also deleted.

Right now, everything is done using a single delayed postback.
