Solution 1

The error tells you exactly what is wrong, which is to tell the application what "Image" class to use so use following code and check your problem will resolve.

C#

System.Drawing.Image a = ((System.Drawing.Image) GridView1.Rows[e.RowIndex].FindControl("Img_Pic"));

Error 5 'Image' is an ambiguous reference between 'System.Drawing.Image' and 'System.Web.UI.WebControls.Image'
Based on which Image control you have used, please update the line of code accordingly. Most probably you are using Image web control and if so, the code should be:

C#

Image a = ((System.Web.UI.WebControls.Image) GridView1.Rows[e.RowIndex].FindControl("Img_Pic")):

Error above just tells that compiler is unable to understand which Image you are talking of.
