ObjectDataSourceControl无法在导入的命名空间中找到类型

Question

I have an aspx page in a ASP.NET 2.0 application using several ObjectDataSources. They are all bound to the same class like so:

<asp:ObjectDataSource ID="TitleDataSource" runat="server" OnSelecting="TitleDataSource_Selecting" SelectMethod="GetTitle" TypeName="DropDownDataSource"></asp:ObjectDataSource>

This was working fine. Then I made two changes

1. Moved the DropDownDataSource from the app_code directory to a separate assembly
2. changed the namespace of the class was com.companyname.ie , now com.companyname.ie.appname

Now I get a "Type Specified in TypeName of 'TitleDataSource' could not be found" error message when I hit the page.

I can fix this by specifying the fully qualified name of the class in TypeName . But adding an <% @import directive with the same namespace does not resolve the error.

I've also tried moving my code back into app_code to no avail.

Intellisense picks up the Type without me specifying the namespace.

Its not a massive problem, but its very annoying. Any suggestions?

Answer 1

Specifying the fully qualified name is correct. Otherwise the runtime will only look in the current assembly.
