Recommendation: Don't use GridView to do this. Use dynamic HTML Javascript Ajax to do this.

But if you really want to do this in GridView, here is one of the way that you can do:

<asp:GridView ID="gv1" runat="server" OnRowDeleting="gv1_RowDeleting">
    <Columns>
        <asp:BoundField DataField="Id" HeaderText="Id" />
        <asp:ImageField DataImageUrlField="PATH" HeaderText="Img"></asp:ImageField>
        <asp:CommandField ShowDeleteButton="true" DeleteText="Delete" />
    </Columns>
</asp:GridView>

At the code behind:

protected void gv1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    // do delete
}
