I have one textbox(textBox1), inside of that textbox there are a lot of lines that are containing, let's say people's names and lastnames, divided by ':', example:
Liam:Williams
Noah:Davis
Lucas:Garcia
Ethan:Lee
There is left side and the right side divided by ':'. My question is: How can I take out what's on the left(or right, doesn't matter) and print it in textBox1?
