Sir i want that when i am updating image file............it already contains that image which i have been inserted.............if i want to change it i do otherwise it saves previous image. 

Hi Indu Yadav,

 

   You can't able to bind value to file upload. so you need to add a new hidden field for already saved file name. When you update the hiddedn filed value is not empty then update the image else dont update the image field.

 

I think this will help you.
