You can use "Split" for this.

myText.Split('.').First();

Just use simple string manipulation:

string text = textBox1.Text;
int firstDot = text.IndexOf('.');
if (firstDot != -1)
{
    string firstPart = text.Susbtring(0, firstDot);
    textBox2.Text = firstPart;
}
else
{
    // Handle case with no dot
}

Fundamentally, this has nothing to do with the text coming from a textbox - it's just a string, really.

var beforeDot = new String(textBox.Text.TakeWhile(c => c != '.').ToArray());

if (mytextvariable.mytext.Contains("."))
  String stuffBeforeTheDot = mytextvariable.mytext.Substring(0, mytextvariable.mytext.IndexOf("."));
