Format How DataTable Column Displays in TextBox On Winform

I am using a BindingNavigator and binding my BindingSource which is a DataTable to a textbox. I am populating the DataTable like this newRow["Email"] = listItem["User_Email_Primary_23x"]; then I am binding the DataTable row to my text box like this [login to view URL]("Text", bindingSource1, "Email"); Now the issue that I have is that data in the DataTable appears like this XXXXXXX@[login to view URL]; XXXXXX@[login to view URL]; XXXXXXXXXX@[login to view URL]; So when the data displays in the text box on the winform it all displays side by side seperated with a semi-colon. What I want to do is update the visual display so that when the email addresses from the DataTable are displayed in the text box each email is displayed on top of each other and have the text box "Auto Expand" so all of the emails are shown. So my desired display results would be XXXXXXXXX@[login to view URL]; XXXXXXXX@[login to view URL]; XXXXXXXX@[login to view URL]; How can this be accomplished?
