<input id="Checkbox1" type="checkbox" runat="server" />可以数据帮定值吗？
我在gridview中有一列是 <input id= "Checkbox1 " type= "checkbox " runat= "server " /> ，我想把数据库中的值帮定到它上面，这么写的
<input id= "Checkbox1 " type= "checkbox " value= ' <%# Eval( "enprid ") %> ' runat= "server " /> ,可是查看生成的原文件却没有值，这是为什么呢？
[解决办法]
runat= 'server ' 的checkbox的值是隐藏了的
[解决办法]
数据里有值吗
这么绑定应该是可以的
[解决办法]
runat= 'server '后值是存放在viewstate中的，如果你要显示则去掉runat= 'server '
[解决办法]
你说的原文件是运行后的HTML源文件，还是编写过程中的源文件
运行后的是应该显示的，如果没有可能就是有问题
[解决办法]
检查Eval( "enprid ")是否有值，是否绑定？

楼主解决了呀？
