Answer 2

还是在html中没的style 效果

Answer 3

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)它有问题,根据自己的代码找问题吧

Answer 4

同一个if 下
  ((Button)e.Item.FindControl("btnDel")).Attributes.Add("onclick", "javascript:return confirm('确实要删除:\"" + ((Label)e.Item.FindControl("lblRoleName")).Text + "\"吗？')");这个就OK

Answer 5

就要乘了，还没解决，关键的是它运行后不出现在html里面

Answer 6

我的ItemTemplate里面包含TABLE <asp:DataList ID="DataList1" runat="server" Width="266px" Height="100px" DataKeyField="RoleId" OnCancelCommand="DataList1_CancelCommand" OnEditCommand="DataList1_EditCommand" OnUpdateCommand="DataList1_UpdateCommand" OnItemDataBound="DataList1_ItemDataBound" OnDeleteCommand="DataList1_DeleteCommand">
                        <ItemTemplate>
                        
                            <table border="0" cellpadding="0" id ="TB" runat="server">
                                <tr>
                                    <td style="width: 100px">
                            <asp:Label ID="labRoleId" runat="server" Text='<%# Eval("RoleId") %>' Width="80px"></asp:Label></td>
                                    <td style="width: 129px">
                            <asp:Label ID="lblRoleName" runat="server" Text='<%# Eval("RoleName") %>' Width="100px"></asp:Label></td>
                                    <td style="width: 100px" align="right">
                            <asp:Button ID="btnMod" runat="server" Text="编辑" CommandName="edit" /></td>
                                    <td style="width: 100px" align="left">
                                        <asp:Button ID="btnDel" runat="server" CommandName="delete" Text="删除" /></td>
                                </tr>
                            </table>
                        </ItemTemplate>
