Bind multiple ComboBox on a form C#

Question

This seems like a simple task but there may be an easier way.

I have a form with 30 comboboxes that all need the same data set. Currently I bind each one:

DataTable t = GetData();

this.ComboBox1.DataSource = t;
this.ComboBox1.DisplayMember = "heading";

this.ComboBox2.DataSource = t;
this.ComboBox2.DisplayMember = "heading";

this.ComboBox3.DataSource = t;
this.ComboBox3.DisplayMember = "heading";

...
...

this.ComboBoxN.DataSource = t;
this.ComboBoxN.DisplayMember = "heading";

Is there a way to bind them all in a less tedius fashion?

Thanks.

Answer 1

foreach (var control in this.Controls)
{
    if (control is (ComboBox))
    {
        ((ComboBox)control).DataSource = t;
        ((ComboBox)control).DisplayMember = "heading";
    }
}

Answer 2

private void bindIt(ComboBox c)
{
    c.DataSource = t;
    c.DisplayMember = "heading";
}

private void bindThemAll()
{
    bindIt(this.ComboBox1);
    bindIt(this.ComboBox2);
    bindIt(this.ComboBox3);
    ...
    bindIt(this.ComboBoxN);
}

That way, you're not running the risk of binding any control which isn't supposed to be bound. Yes, lots of repetition, but ....
