I'm working on a database in C# when I hit the display button I get an error:

Error:
Cannot bind to the property or column LastName on the DataSource. Parameter name: dataMember

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.
}

Not sure what it means can anyone help, if I comment out the last two lines it will display properly.

Another reason for this error is if the property you are binding to is private.

Yet another possible reason for this (if you bind to an object) is that you try to bind to a field, not a property.

I run into the same problem where I have to change the name in the table but I haven't change column names in the data binding file. solution was changing the names by replacing the changed name.
