At a time means? In one click do you want to select all 10?

Solution 1

MIDL

foreach (Control c in this.groupBox1.Controls)
{
    if (c.GetType() == typeof(CheckBox))
    {
        ((CheckBox)c).Checked = true;
    }
}

Where you want. Think logically. Can be even before UI is shown (form constructor), one some event...

Solution 2

You can do this way also,

foreach (CheckBox c in groupBox1.Controls)
      {
        if (c.Checked == false)
           c.Checked = true;
      }

Write above code in Page Load and check it out .....

Once you get your checkbox then you can write your logic inside foreach loop.
