I know we can show image thumbnails in a gridview...but what about thumbnails of word documents and pdf files?
I know we can put an icon image in the row...but is there a way to show a large thumbnail of the actual document?
I have a datagrid which pulls data from a single database table to display it. However, this database table also contains information on the thumbnail URL for each record, and I would like to display the thumbnails for each record in the 1st column of the datagrid.
At present I have added the following to my datagrid:

So I presume the main challenge now is to set the Thumbnail.ImageUrl property to the correct file path in the VB.NET code. But how do I do this for each record? I am using a function to retrieve data for the gridview, which is based on the following:

I need to create a thumbnail solution in order to display pictures of products.
There can be more than 1 thumbnail per product and I need a way to enlarge the image as well. The thumbnails will be displayed in atleast 3 or 4 pages across the system and I need the ability to delete them as well. For version 2 of the software (knowing PM's it may be thrown into Version 1), I think I will need to be able to enhance this feature to allow movie clips so that's something I need to keep in mind. The images will be stored in the DB so I can sort the code to retrieve them but I'm originally a windows programmer and this is my first major ASP.NET project and also my first attempt at C#.

I am trying to export my GridView info to a readable csv file. Unfortunately, attached is what is shown. Under the Date column, a few dates show up (8/9/2010) but when it switches to 8/10/2010 -8/31/2010 it only shows ######, BUT when I move the mouse over the #######'s it shows the date in the little box thing.

Response.ContentType = "application/text";......
