Bind Image to GridView using Eval

Use below code to add image inside a GridView.

<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField HeaderText="Contact" HeaderStyle-HorizontalAlign="left" ItemStyle-HorizontalAlign="left" >

 <HeaderTemplate> Cover Image </HeaderTemplate>

 <ItemTemplate> 

 <asp:Image ID="imgCover" runat="server" AlternateText="Image Cover" ImageUrl='<%# Eval("Cover_Path") %>' /> 

 </ItemTemplate> 

 <HeaderStyle HorizontalAlign="Left">

</HeaderStyle>

 <ItemStyle HorizontalAlign="Left">

</ItemStyle> 

 </asp:TemplateField>
</Columns>
</asp:GridView>

Remember to use virtual path for Eval("Cover_Path"), not the full path. Something like below.
