title: DataSource error: "Cannot Bind to property or Column"
body: <p>I'm working on a database in C# when I hit the display button I get an error:</p>
  
  <blockquote>
    <p>Error:<br>
    Cannot bind to the property or column LastName on the DataSource.
    Parameter name: dataMember</p>
  </blockquote>
  
  <p>Code:</p>
  
  <pre><code>private void Display_Click(object sender, EventArgs e)
  {
      Program.da2.SelectCommand = new SqlCommand("Select * From Customer", Program.cs);
      Program.ds2.Clear();
      Program.da2.Fill(Program.ds2);
      customerDG.DataSource = Program.ds2.Tables[0];
  
      Program.tblNamesBS2.DataSource = Program.ds.Tables[0];
  
      customerfirstname.DataBindings.Add(new Binding("Text", Program.tblNamesBS2, "FirstName"));
      customerlastname.DataBindings.Add(new Binding("Text", Program.tblNamesBS2, "LastName")); //Line Error occurs on.
  }
  </code></pre>
  
  <p>Not sure what it means can anyone help, if I comment out the last two lines it will display properly.</p>
