WebTextEditor1.TextMode = TextBoxMode.MultiLine
WebTextEditor™ can easily be configured for multiline mode where you can specif the number of lines and characters per line to be displayed by setting the MultiLine object’s Rows and Columns properties. You can also set the MultiLine object’s Wrap and Overflow properties to wrap the text in the text area and control the overflow style respectively.
To use WebTextEditor in multiline mode you must set the control’s TextMode property to MultiLine. You can set the TextMode property to MultiLine either by using the Microsoft® Visual Studio® Property Window or by using the following code:
In Visual Basic:
WebTextEditor1.TextMode = TextBoxMode.MultiLine
In C#:
WebTextEditor1.TextMode = TextBoxMode.MultiLine;
