    <p>I am building a simple C# application that allows the user to edit the rows of a table in a database. The interface is very simple, it is basically a list of rows and a few buttons. Selecting a row and pressing the "Add" button pops up a new form with text boxes for each column. I want those columns to be populated with the values for the selected row.</p> <p>After reading a few articles, I found that probably the simples way to do this is to bind the Text property of the TextBox to a DataSource. So I store the values from the database in a DataTable object, with the plan of retrieving the selected DataRow and binding its to the TextBox. This is the line I use:</p> <pre><code>productNameTextBox.DataBindings.Add(new Binding("Text", productRow, "Name")); </code></pre> <p>The result is the following exception:</p> <blockquote> <p>A first chance exception of type 'System.ArgumentException' occurred in System.Windows.Forms.dll Cannot bind to the property or column Name on the DataSource. Parameter name: dataMember</p> </blockquote> <p>And yes, the "Name" column does exist.</p> <p>After reading according to the documentation of bindings (http://msdn.microsoft.com/en-us/library/4wkkxwcz(v=VS.80).aspx) and many examples, it seems to me that one has to bind to the DataTable that the row is contained in. The following code worked for me:</p> <pre><code>productNameTextBox.DataBindings.Add(new Binding("Text", productRow.Table, "Name")); </code></pre> <p>Except it always sets the value of the TextBox to the first row. How do I specify which row to use?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
