How do the different data presentation controls equate in ADO.net?
How does Visual Studio create ado.net equivalents of the datagrid's and gridview's columns and rows? I am assuming they make a DataRow for each of the rows. Am I on the right track with this?Is the table created by gridview basically a dataset from ADO.net? Can anyone offer any guidance with this?Thanks to everyone that has ever helped me with any posts.
The row in datagrid is called DataGridItem and in gridview is called GridViewRow. They are all inherits TableRow Class. DataRow is only one kind of row in GridView control. There are many other t...Does .NET map calls for ADO to ADO.NET?
Hello,We are trying to troubleshoot some DB problems from COM objects that call ADO. I heard that when ADO is loaded inside of a COM object by a .NET app, that .NET intercepts the call and re-maps those calls over to ADO.NET. This seems untrue to me, given the nature of ADO.NET being a totally separate technology.Does anyone know for sure whether this does or does not occur?The problem we are seeing is actually almost identical in symptoms to this:http://support.microsoft.com/default.aspx/kb/230101"FIX: Data Queries Sporadically Return Empty Recordsets" Literally, this is what...ADO in VB6 vs ADO.NET in VB.NET
I am writing a database interface and I would like to know whether a
VB6 interface using ADO or a VB.NET interface using ADO.NET would be
faster in terms of just performing database operations. Is there an
explanation for this, and what is the magnitude of the difference?

I have to connect to a db using adodb (which i select from the references). I have to retrieve the car models from the database and bind them to a listbox. I am not sure how to proceed and I can't find any articles on ADO with .net and data binding.
Here is the code that i tried but it only retrieves the car model for the specified id. If I delete the id it doesn't work. Also it writes the car model in the listbox vertically such as:

Background: I'm making the transition from PHP to ASP.Net, and I am using Visual Studio 2005.My question is: Are there general guidelines for when to use the Data Controls over the ADO.Net classes, and vice versa?I'm used to doing everything manually, so I'm leaning towards just using ADO.Net. My gut reaction is that cookie-cutter approaches like the data controls will be limiting with more advanced applications. Do you typically use one or the other, or do you typically find a balance and end up using some of each?Let me know what you think. Thanks!

What are the pros and cons of using ADO.net vs Data bound controls? I know data bound controls might be resource heavy, but alot of tutorials are pushing bound controls (SQLDataSource control and ObjectDataSource Control)I would love to hear anyones opinions and experiences.ThanksMike.
The reason why many tutorials use Data controls is because many times the articles want save time and focus on other core concepts and Data controls allow us to cut down on the data base related code so that the author can focus on the main topic. Another reason is that Data controls are perfect fo...ADO to ADO.NET help

I am very new to ADO.NET and am a bit confused on how I would convert this.
Basically what I am trying to do is capture the name of the fields of a table to populate a dropdownlistbox. The table name will change every time the program is run. This is not a problem and I can code for that.
Here is what I have in ADO (I have tried the wizard but it did not change the code)
