GridView怪问题，望高手进来看看

Question

在做GridView绑定的过程中为了实现单击行，此行变色的时候
发现一个怪现象
就是在单击零行时，该行的颜色没有任何的变化，不知道为什么
下面是我的代码：劳驾高手看看前台：
asp:GridView ID="gvLeveling" runat="server" AutoGenerateColumns="False" 
                BorderColor="#000000"  BorderWidth="1px" CellPadding="3" meta:resourcekey="gvLevelingEmpty" OnRowCreated="gvLeveling_RowCreated" OnRowDataBound="gvLeveling_DataBound">
                <Columns>
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="project_name" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="project_cd" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="project_importance" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="pstart_date" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="pfinish_date" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="status" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="lstart_date" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="lfinish_date" />
                    <asp:BoundField ItemStyle-HorizontalAlign="Center" ItemStyle-BorderColor="#000000" DataField="message" />
                </Columns>
            </asp:GridView>

    }以上都是部分代码

Answer 1

你在head下面加了一行,所以就不会变色了.

Answer 2

e.Row.Attributes.Add("onclick", "if(window.oldtr!=null){window.oldtr.runtimeStyle.cssText='';}this.runtimeStyle.cssText='background-color:#e6c5fc';window.oldtr=this");你这什么意思？
开始你的window.oldtr是NULL吧

Answer 3

对
juedaihuaihuai(绝代坏坏（beyond myself）) 
我也试过，不用畸形表头，
该方式也一样在第一行不能变色

Answer 4

honkerhero(做事先做人) 开始你的window.oldtr是NULL吧
是等于NULL因为只有window.oldtr是NULL的时候才给该行变色
