DataBinding Through Code

1 New Member
Hi all. This is my first post… be gentle :)

I'm not looking for the code to make it work... if you could just point me in the right direction... I am self-taught and really need to learn by doing rather then having it given to me. Thanks all!

I have a WinForm with a single ListBox and several TextBoxes. I have an SQL database in the project. I am currently using a connection string to open and read the data filling a dataTable. I have set my ListBox Source and DisplayMember which are working properly. My ListBox displays LastName, FirstName as it should by combining the LastName and FirstName fields in the commandString.

My issue is how I achieve dataBinding/concurrency without using “drop and drag” binding within Visual Studio?

I have to cycle through the records in the ListBox and have the corresponding TextBoxes display the record information. I understand using the SelectedIndexCh anged event for the listbox but I’m missing the “piece” to make the whole thing work.

Here is the code to open, read and fill listbox:

Expand|Select|Wrap|Line Numbers
  1. string connectionString = "Data Source=walsh\\sqlexpress;Database=PPDOne_db;Integrated Security=True;";
  2.             SqlConnection conn = new SqlConnection(connectionString);
  3.             string commandString = "SELECT *, NameLast +', ' + NameFirst AS NameFull FROM tblAdvocates ORDER BY NameLast";
  4.             SqlDataAdapter dataAdapter = new
  5.             SqlDataAdapter(commandString, conn);
  6.             DataSet ds = new DataSet();
  7.             dataAdapter.Fill(ds, "prog");
  8.             dataTable = ds.Tables["prog"];
  9.             lbxAdvocates.DataSource = ds.Tables["prog"].DefaultView;
  10.             lbxAdvocates.DisplayMember = "NameFull";
  11.             lbxAdvocates.SetSelected(0, true);
  12.             conn.Close();
Any help would be appreciated!

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

Hello everyone, I know this question has been asked many times in the forums, and after spending a few days reading, I am still confused as to the answer.

Here is the design of my simple tables: (An example since I can't post my...

I'm writing what should be a very simple app against an Oracle database. The app has a number of user controls, any one of which is loaded into a main display page using the loadControl method, depending on which menu item a user selects. Each of these controls follows the same basic pattern: Get a dataset from the database and then display the results using basic databinding. Everything works fine except that I'll occaisionally get an...

When I first built a few web pages in ASP .Net 2.0, I thought it was great. The formview and detailview contorls would automatically layout the controls for you, the update methods were automatically generated, and the objectdatasource let you design against a business object through the gui. Now I am working on my first real web application on 2.0, and I find this automatic functionality doesn't do much beyond allowing me to generate...

In 1.1 we always did our own myDataAdapter.fills and we liked that control for lots of good reasons. Now the new DataSource (or is it a TableAdapter:Dataset) automatically fills the Gridview. How can we control that fill? In a...

Hi all, I may be missing something with how databinding works but I have bound a datasource to a control and everything is great, the control updates to reflect the state of my datasource when I update the datasource - awesome, but I have an issue with updating from a different thread.

Hello to all, I want to know if DataBinding in asp.net 2,0 is better than to fill up the values of the controls of the following form: this.miControlTextBox.Text = valorParaControlTextbox; Performance with databinding is good in asp.net 2.0 ? Would you prefer: databinding or set value to Text property of control ?

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
