Textbox not storing the information and others do if not null of empty

Question

I'm trying to make that theirs a check if a textbox is empty, it wont pass the information on multiple textboxes on a button press, example:

 private void button1_Click(object sender, EventArgs e)
    {
        if (this.Controls.OfType<TextBox>().Any(t => string.IsNullOrWhiteSpace(t.Text)))
        {
             // what can i put here to exclude multiple
        }
        else
        {
            //if any of thouse are empty i dont want them to do this but if they are not empty i do want
            lablCinnamonset.Text = textBox1.Text; 
            lablMallardset.Text = textBox2.Text;
            lablAxisdeerSet.Text = textBox3.Text;
            lablBlackbuckSet.Text = textBox4.Text;
            lablMuledeerSet.Text = textBox5.Text;
            lablReddeerSet.Text = textBox6.Text;
            lablPumaSet.Text = textBox7.Text;
            lablWaterbuffaloSet.Text = textBox8.Text;
            lablJackrabbitSet.Text = textBox9.Text;
            lablCoyoteSet.Text = textBox10.Text;
            lablWhitetailSet.Text = textBox11.Text;
            lablBlacktailSet.Text = textBox12.Text;
            lablBlackbearSet.Text = textBox13.Text;
            lablRooseveltSet.Text = textBox14.Text;
            lablMooseSet.Text = textBox15.Text;
        }

I don't want to do, a if statement for each textbox, it has to be a better way.

Thank you guys

Why don't just extract a method?

  private static void AssignIfNotEmpty(Control target, Control source) {
    if (!string.IsNullOrWhiteSpace(source.Text))
      target.Text = source.Text;
  }

Then use it

private void button1_Click(object sender, EventArgs e) {
  AssignIfNotEmpty(lablCinnamonset, textBox1); 
  AssignIfNotEmpty(lablMallardset, textBox2);
  AssignIfNotEmpty(lablAxisdeerSet, textBox3);
  AssignIfNotEmpty(lablBlackbuckSet, textBox4);
  AssignIfNotEmpty(lablMuledeerSet, textBox5);
  AssignIfNotEmpty(lablReddeerSet, textBox6);
  AssignIfNotEmpty(lablPumaSet, textBox7);
  AssignIfNotEmpty(lablWaterbuffaloSet, textBox8);
  AssignIfNotEmpty(lablJackrabbitSet, textBox9);
  AssignIfNotEmpty(lablCoyoteSet, textBox10);
  AssignIfNotEmpty(lablWhitetailSet, textBox11);
  AssignIfNotEmpty(lablBlacktailSet, textBox12);
  AssignIfNotEmpty(lablBlackbearSet, textBox13);
  AssignIfNotEmpty(lablRooseveltSet, textBox14);
  AssignIfNotEmpty(lablMooseSet, textBox15);
}

You may want to organize your controls e.g.

public partial class MyForm : Form {
  private Dictionary<Label, TextBox> m_Correspondence = 
    new Dictionary<Label, TextBox>();

  public MyForm() {
    InitializeComponent();

    m_Correspondence.Add(lablCinnamonset, textBox1);
    m_Correspondence.Add(lablMallardset, textBox2);
    ...
    m_Correspondence.Add(lablMooseSet, textBox15);
  }

In this case button1_Click will be very simple:

private void button1_Click(object sender, EventArgs e) {
  foreach (var pair in m_Correspondence)
    AssignIfNotEmpty(pair.Key, pair.Value);
}
