I have a generic Repository<T> class I want to use with an ObjectDataSource. Repository<T> lives in a separate project called DataAccess.

A class amonst many others set up in a very similar fashion. I select the class and click Next to pick the function for the SelectMethod and it closes wit...
Hello, I have an ObjectDataSource with an ID of ObjectDataSource1 on a webpage. I also have a gridview in which I am binding the ObjectDataSource.ID to the GridView.DataSourceID. The problem I get is when text is changed in a textbox, the code calls BrokerageTransactions.GetAllWithDt which returns a DataTable. I want to set this data...

I'm using an ObjectDataSource to bind data to a GridView; it works fine except that it always creates a new object to use as a data source. I can do all the setup just fine but I cannot use an instance of an existing object to specify as the "data source" for it. Is it possible to do this? If so, how? If it's not possible, why? ED...
I am accessing a business class using an ObjectDataSource and trying to produce output that makes sense to the user. The return values describe a Class (as in Classroom and teaching, not software). I would like to show the time of the class as a range like this: "9:00 AM - 10:00 AM". This is the Linq Query I am using to pull the data:...
Hi, I have an objectdatasource that will return a potentially large collection (up to 200,000 records) that are bound and paged in a gridview. I am using default paging and caching on the objectdatasource. The data being returned is only updated weekly so stale data is not an issue. The paging in this solution was also faster than w...
I'm new to MVC, and am not following how you'd do paging and sorting on a grid. I'm used to using the asp.Net GridView control with an ObjectDataSource pointed at objects in our business layer - and in that case the ODS handles all of the paging & sorting using the methods that our ORM generates on the objects. I've looked at using the...
Normally if I'm linking an ObjectDataSource to a GridView and I have a TemplateColumn that has an Eval in it and it's Null, I can just put a ".ToString()" it works fine. For some reason, this doesn't work the same when you're using Linq to SQL. I originally was using XSD files for my DAL with a custom BLL. I tied it to the GridView wi...
I have a gridview that has its DataSourceID property set to a custom ObjectDataSource object. When AllowPaging is set to True, the GridView disappears after a postback. If I set AllowPaging to False it's fine. Can someone shed some light on this for me? :) Edit: The other thing I'm confused about is I thought that if you set the DataSou...
