Gridview中事件怎么不响应。【急】

Question

情况一： 
<asp:GridView ID="gvFriend" runat="server" AutoGenerateColumns="False" CellPadding="4" 
                        GridLines="None" CellSpacing="1" BackColor="#EEEEEE" Width="577px" OnRowCommand="gvFriend_RowCommand" 
                        BorderStyle="Groove" AllowPaging="True" AllowSorting="True" OnRowDataBound="gvFriend_RowDataBound" 
                        OnRowCreated="gvFriend_RowCreated" OnRowDeleting="gvFriend_RowDeleting" OnPageIndexChanging="gvFriend_PageIndexChanging" 
                        OnSorting="gvFriend_Sorting"> 
<PagerSettings Mode="Numeric" /> 
                        <RowStyle BackColor="White" BorderColor="#EEEEEE" /> 
                        <Columns> 
                            <asp:TemplateField HeaderText="番号"> 
                                <ItemTemplate> 
                                    <%# (Container.DataItemIndex+1).ToString()%> 
                                </ItemTemplate> 
                            </asp:TemplateField> 
                            <asp:BoundField DataField="UserID" HeaderText="用户ID" /> 
                            <asp:BoundField DataField="UserName" HeaderText="用户名" /> 
                            <asp:BoundField DataField="Sex" HeaderText="性别" SortExpression="Sex"/> 
                            <asp:BoundField DataField="Age" HeaderText="年龄" SortExpression="Age" 
                                ItemStyle-HorizontalAlign="Right" > 
<ItemStyle HorizontalAlign="Right"> </ItemStyle> 
                            </asp:BoundField> 
                            <asp:BoundField DataField="Status" HeaderText="Status"> 
                                <ItemStyle CssClass="hidden" /> 
                                <ControlStyle CssClass="hidden" /> 
                                <HeaderStyle CssClass="hidden" /> 
                                <FooterStyle CssClass="hidden" /> 
                            </asp:BoundField> 
                            <asp:TemplateField HeaderText="操作" ShowHeader="False" ItemStyle-Width="100"> 
                                <ItemTemplate> 
                                    <asp:Button ID="btnAdd" runat="server" CausesValidation="false" CommandName="Add" 
                                        Text="加入" onclick="btnAdd_Click"> </asp:Button>                                 </ItemTemplate> 点击加入按钮时，报“未能加载视图状态。......."错误。 情况二： 
在Gridview 中加上 enableView = "false"。错误是不报了，但是后台只进入Page_Load， btnAdd_Click和gvFriend_RowCommand都没有进去。不知道为什么。 

Answer 1

<asp:Button ID="btnAdd" runat="server" CausesValidation="false" CommandName="Add" 
                                        Text="加入"></asp:Button>添加gridview的rowcommand事件
 protected void gridview1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Add")
        {            
//do here
        }
}

Answer 2

在Gridview 中加上 enableView = "false"。
gridview就没有状态了，就不知道发生了什么事情，就不会触发事件的

Answer 3

我的前台代码里面已经加上rowcommand事件了，但是就是响应不了。

Answer 4

但是不加enableView = "false"。
就会报错。
