I've a form view with various field in edit and an object datasource where I've defined my update parameters that my update method takes. I've set some of the fields in the edit template to read only because I want them to display. Unfortunately they are getting passed in as update parameters somehow to my objectdatasource. So, it is ge...
Working with .NET 2.0, I have a FormView with fields bound to an ObjectDataSource (ODS). Those fields start out with the correct values—that is, they come from the Person object when the ODS’s SelectMethod is called—but after making changes and calling the ODS’s UpdateMethod, I can’t get these new—or any—values from the fields from anyw...
Howdy, Recently I returned to ASP.NET WebForms programming and I've come across a problem that I'm sure was not an issue previously. I have a Customer object with and Address object, I can bind up to all the properties of the customer (including the address for display) but when the formview binds back it throws an exception say that...
I'm trying to upgrade some Sharepoint 2007 webparts to SP2010 using the web part projects built into Visual Studio 2010. Namely, I'm using Visual Web Part to migrate our existing controls, which make extensive use of ObjectDataSource. However, when adding an ODS to the control in the Visual Web Part project, it will not pick up objects i...
Hi, I want to sort my gridview binded to an object datasource fetching business objects. I have already implemented custom paging & now want to implement sorting. Just read this article but there is lot of concatenation going on there with the SQL Query. Any other elegant solution guys ? http://aspnet.4guysfromrolla.com/articles/032206-...
So, the context of this question is pretty specific, but I think there is a general C# question struggling to get out. :) I have an ASP.NET Web Forms page with a GridView control bound to an ObjectDataSource. The data source control is hooked to a data access class that, in turn, uses LINQ to query Entity Framework v4. The methods on t...
I am trying to hook up custom pagination with an ObjectDataSource to my GridView. However, this thing renders no data, but does render the column headers. The debugger clearly indicates a populated DataTable being returned: <asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource1" AllowPaging="True" /> <asp:ObjectDat...
Hello all. I have the following bit of code that gives me the number of rows in a gridview bound to an object data source. protected void odsProduct_Selected(object sender, ObjectDataSourceStatusEventArgs e) { lblHowManyRows.Text = ((List<tblProduct>)e.ReturnValue).Count.ToString(); Lovely. However, how would I g...
Hello all. I have the following scenario I would like to implement. I have a number of drop downs that the client can select a range of criteria.

Is it possible to get to the object that an ObjectDataSource creates when calling the select function? Not the result of the select function itself but the object that is creates from the parameter specified in TypeName. I would like to call some other functions on that same instance after Select is called. The other solution would be ...
So, this question may be a little vague, but I have constant discussions about it: When designing an Asp.Net page, a lot of times you might just want to throw a quick and dirty GridView on the page. When you are going that route you have the various datasource options (I typically use ObjectDataSource tied to a business object) and you...
