WPF Multiline Textbox Example

Introduction

In Windows Forms, it's easier to set TextBox control as multiline by setting MultiLine="True". But with WPF, you will not find multiline property for TextBox control. So in order to make WPF textbox as multline set below 3 properties

AcceptsReturn="True" {If false you can not press enter key}
TextWrapping="Wrap" {If NoWrap then text keeps on going to right side in same row}
VerticalScrollBarVisibility="Visible" {If property is not set you have to use up/down keys or mouse wheel to see content}

Texbox Code

<TextBox AcceptsReturn="True" TextWrapping="NoWrap"  VerticalScrollBarVisibility="Visible"/>

Example:

<Window x:Class="DotNetMirror.WPFMultiLineTBWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Demo : Multiline Textbox in WPF" Height="300" Width="300">
    <StackPanel Orientation="Vertical">
        <Label Content="Multiline Textbox in WPF"></Label>
        <TextBox Height="200"  Name="tbmlName" AcceptsReturn="True" TextWrapping="NoWrap"  VerticalScrollBarVisibility="Visible"/>
    </StackPanel>
</Window>
