What am i doing wrong please help me with this

Answer 1

Set image url in aspx , something like this

<ItemTemplate> 
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "your_path" + "ProductImage" %>'  
   Height="300px" Width="300px"/>
</ItemTemplate>

Plese make sure your_path is physical path where image is stored, for example "~/images/myimg" and your image name is valid, for example image.jpg or image1.png

by this method you can show image in gridview.
