objectdatasource

问题 My question is similar to this one but I'm having some problems with the actual implementation. I've got a report (.rdlc) in the business layer of a 3-tier app. I've got an object in the BL ( EmployeeManager ) which has a GetEmployees(Expression as Expression(Of Func(Of Employee, Boolean))) As IQueryable(Of Employee) method.

问题 Is there any way to make asp.net objectdatasources to be type safe. Meaning I get a compile time error if parameters or datatypes change during refactoring? Does anyone know any other method? Or can recommend any other way to do it? I find manual binding tedious. What is other people doing? Thanks 回答1: No, all binding is with strings holding property/column names. Maybe consider a Test project (Unit testing). That would be my answer to the last part. 来源： https://stackoverflow.com/questions

Here is my DL method: public static Collection<AdminUserEntity> GetUsers(ClientEntity currentClient) { } So when I configure my ObjectDataSource I choose the AdminUserEntity as the buisness object to bind to and then choose GetUsers as the Select method but as you see it takes a complex type as a parameter and I don't know how to specify this using the wizard or manually. After some more digging I

问题 I have a gridview to which I have created an Insert Template in the footer row. I have an ObjectDataSource which is bound to a business object. I have an OnInserting event handler which never gets fired. The program encounters an error once I call .Insert on the ObjectDataSource.

I have seen mention of grabbing
