How do you add null validation to text box?

When the user leaves the text box empty and presses the enter button it lets the user enter nothing to the list.I want it to show a message and not let them show nothing

Use an if statement

If is empty Textbox.Text
Then Display message
Else do the processing

You can find the is empty block in the text drawer
