Answer 1

可以的  AlternatingItemStyle-BackColor属性...
下面这个DataGrid还实现了onmousevoer事件
<asp:DataGrid ID="MessageList1" runat="server" Width="90%" AutoGenerateColumns="false" AlternatingItemStyle-BackColor="#ccccff">
        <HeaderStyle HorizontalAlign="Center" BackColor="#ddddee" />
        <Columns>
          <asp:TemplateColumn HeaderText="用户" HeaderStyle-Height="25px" ItemStyle-HorizontalAlign="Center" ItemStyle-Width="35px">
            <ItemTemplate>
              <span id='span<%#Eval("id")%>'></span>
              <%#Eval("username" )%>              <script type="text/javascript" language="javascript"> 
                var originalColor;          
                document.getElementById('span<%#Eval("Id")%>').parentElement.parentElement.onmouseover=function(){                  
                  originalColor=this.style.backgroundColor;
                  this.style.backgroundColor="#eeeeee";                      
                }
                document.getElementById('span<%#Eval("Id")%>').parentElement.parentElement.onmouseout=function(){
                  this.style.backgroundColor=originalColor;
                }  
              </script>            </ItemTemplate>
          </asp:TemplateColumn>
          <asp:TemplateColumn HeaderText="URL地址">
            <ItemTemplate>
              <%#HttpUtility.UrlDecode( (string) Eval("url")) %>
            </ItemTemplate>
          </asp:TemplateColumn>
          <asp:TemplateColumn HeaderText="反馈消息" ItemStyle-Width="400px">
            <ItemTemplate>
              <%#Eval("message") %>
            </ItemTemplate>
          </asp:TemplateColumn>
          <asp:TemplateColumn HeaderText="反馈时间">
            <ItemTemplate>
              <%#Eval("Time") %>
            </ItemTemplate>
          </asp:TemplateColumn>
          <asp:TemplateColumn HeaderText="回复" ItemStyle-Width="50px">
            <ItemTemplate>
              <a href="Reply.aspx?UserName=<%#Eval("username")%>" target="_blank" style="text-decoration: none"><span style="color: #885533">回复用户</span></a>
            </ItemTemplate>
          </asp:TemplateColumn>
          <asp:TemplateColumn HeaderText="备注(可编辑)">
            <ItemTemplate>
              <input type="text" style="border: none; background-color: transparent;" id="<%#Eval("id") %>" value="<%#Eval("re") %>" onblur="Insert_Re(this)" />
            </ItemTemplate>
          </asp:TemplateColumn>
        </Columns>
      </asp:DataGrid>
