  Hi,

  Seem your source code is ok, and I suggest to comment this code line:

  sc_quest.Dispose();

  This Dispose method always is called after you execute this component(here is SqlCommand):

  http://msdn.microsoft.com/en-us/library/3cc9y48w

  The code binding the value of path to ImageUrl property of Image control is ok, why doesn't the image be displayed? Please confirm whether the path of image is corrcect.

  BTW, any error you can locate it by debuging your source code step by step and then resolve it.

  Please mark the replies as answers if they help or unmark if not.
