Answer 1

　class="input2" style="width:98%;" Height="300px" 先cut了,然后一个一个属性增加,你自然就找到为啥错误了.

Answer 2

style="width:98%;"多了个分号

Answer 3

错误有可能在designer文件那边。删除了之后重新添加一遍。

Answer 4

textbox没有class和style属性设置啊，LZ
用CssClass吧去写样式吧

Answer 5

确认错误在 <asp:TextBox ID="tcontent" runat="server"　class="input2" style="width:98%;" Height="300px" TextMode="MultiLine"> </asp:TextBox>这里?

Answer 6

删除 class="input2" 这个属性值，就好了

Answer 7

 style="width:98%;" Height="300px" 应改为
width="98%" Height="300px"

Answer 8

style="width:98%" 是html控件时的写法.对于服务端控件.应改写为:width="98%" 

Answer 9

class="input2"  应改写为: CssClass="input2" 前者是HTML控件写法,后者是服务端控件的写法

Answer 10

style="width:98%;"多了个分号
