大侠帮忙啊！！！！写了一个自定义控件，继承自datagrid，编译的时候能通过！为什么把他拉到界面就出错呢？？

[ldw701]

编译的时候出错信息：
D:\WebSites\Test\TestVaildClient.aspx(12,31): error CS0433: The type 'SoftReg.UserDataGrid' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.40607\Temporary ASP.NET Files\test\f0a45bd4\be3552d5\assembly\dl2\v2_d67516a7\00e33ad1_0efac401\UserDataGrid.dll' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.40607\Temporary ASP.NET Files\test\f0a45bd4\be3552d5\__codewdyus4_s.dll'

删除你的BIN目录下的DLL试试！

[yitiaocheng_10]

编译是编译自定义控件的时候还是在你现在用这个自定义控件的项目里?

[ldw701]

是在项目里，编译dll的时候没有问题，就是把这个控件添加到toolbox里面，再拉到页面上，编译工程的时候报这个错！

[time_is_life]

可能是强名的问题

救命啊。。。。。。。。

[dotnet90]

把你编译成dll的源代码从项目中排除保证没有问题了

[time_is_life]

你最好把代码贴出来,不然没有办法给你分析,还有,你的控件又没有用强名?

切换一下Debug/Release编译成功后再切换回来

求救！！！！

[Netmark]

我怎么感觉你这是写的派生自DataGrid的一个类

而不是一个组件

怎么没有override 重写
