使用VB.net编辑动态数据中的DropDownList [英] Editing DropDownList in Dynamic Data using VB.net

问题描述

嗨
我有两个表User& UsersInRoles

用户表已获得:

用户ID

姓氏

Sirname

等

UsersInRoles已获得:

UsersInRolesID

用户ID

RoleID

(仅3列)

我有两个下拉菜单

角色:只读/管理/编辑

用户:John/Harry/Chris

& 路径为/UsersInRoles/Insert.aspx

现在，我想在用户下拉列表"中显示姓氏+姓氏".我添加了一个名为UsersInRole.vb的类文件，代码如下:

< MetadataType(GetType(UsersInRoleMetaData))> _
部分公共类UsersInRole

< uihint("userinrole_enumeration")>
公共ReadOnly属性FullUserName()作为字符串
获取
Dim x As String = Me.User.Forename& "& Me.User.Surname
返回x
结束获取
最终财产

结束类

< displayname("user> 在UsersInRoles中找不到属性".

谁能告诉我，我在哪里做错了.我的意思是我真的很困惑，在哪里进行更改以及应该添加哪个新文件.谁能给我发送一些结构解决方案.这将是很大的帮助.

希望很快能收到您的回音.

谢谢

Hi
I have two tables User & UsersInRoles

User Table has got:

UserID

Forename

Sirname

etc.

UsersInRoles has got:

UsersInRolesID

UserID

RoleID

(Just 3 Columns)

I have two dropdowns

Role : Readonly/Admin/Edit

User: John/Harry/Chris

& the path is /UsersInRoles/Insert.aspx

Now, I want to display the Forename + Surname in User DropDown. I added a class file with the name UsersInRole.vb and the code is below:

<MetadataType(GetType(UsersInRoleMetaData))> _
Partial Public Class UsersInRole

<uihint("userinrole_enumeration")>
Public ReadOnly Property FullUserName() As String
Get
Dim x As String = Me.User.Forename & " " & Me.User.Surname
Return x
End Get
End Property

End Class

<displayname("user>Property not found in UsersInRoles".

Can anyone please tell me, where am I doing the wrong. I mean I am really confused about it, where to make the changes and which new file should I add. Can anyone please send me some solution with structure. It would be a great help.

Looking forward to hear from you soon.

Thanks

推荐答案

您是否已经有一个名为UsersInRoles的类?为什么不将属性添加到该类而不是使用局部类呢? Me.User与角色表中的用户有何关系? Me.User是与实例中的UserId关联的User吗?我认为我们还需要查看其他类，并且我们还需要知道什么代码会产生此错误.

Did you already have a class called UsersInRoles ? Why not add the property to that class instead of using a partial class ? How does Me.User relate to the users in roles table ? Me.User is the User associated with the UserId in the instance ? I think there''s other classes we need to see, and we also need to know what code generates this error.
