Error is self describing.look at that. :) I think you defined DataSourceID in the html.Check your html for GridView and remove that. :)

Because, I guess, You are using Two Data Source for GridView1. One From Code Behind. and Another is on ASPX PAge. As per my article goes, Displaying Image in Gridview from Database[^] There is only one datasource that is created only on CodeBehind. Remove DataSourceID of GridView From aspx page.

Show us the code of GriView from aspxpage. And DataBind code from Codebehind page.

Instead of ((Image)e.Row.FindControl("img_1")).ImageUrl = "'@~/Upload/'" ; give something like, ((Image)e.Row.FindControl("img_1")).ImageUrl = @"~/Upload/imagename.jpg" ; where imagename is the path from object source. :)

where to give the path
Image path should be the database column . And physically your image storage location would be hard drive. When you will retrieve the path from database, image will be load from drive. The Article, which you have mention above, clearly explained each and every steps. :)
