I have a TextBox and a Label. After clicking a button, I execute the following code:
label1.Content = textbox1.Text;
My question is, how do I enable text wrapping of the label? There may be too much text to display on one line, and I want it to automatically wrap to multiple lines if that is the case.
The Label control doesn't directly support text wrapping in WPF. You should use a TextBlock instead. (Of course, you can place the TextBlock inside of a Label control, if you wish.)
Sample code:
<TextBlock TextWrapping="WrapWithOverflow">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec adipiscing
nulla quis libero egestas lobortis. Duis blandit imperdiet ornare. Nulla
ac arcu ut purus placerat congue. Integer pretium fermentum gravida.
</TextBlock>
TextBlock with TextBox? -- TextBlock's have been read-only since WPF was code named "Avalon".
Padding="5" to match the padding in my other Label controls on the form. See Rajesh's answer below.I used the following code.
<Label>
<Label.Content>
<AccessText TextWrapping="Wrap" Text="xxxxx"/>
</Label.Content>
</Label>
Often you cannot replace a Label with a TextBlock as you want to the use the Target property (which sets focus to the targeted control when using the keyboard e.g. ALT+C in the sample code below), as that's all a Label really offers over a TextBlock.
However, a Label uses a TextBlock to render text (if a string is placed in the Content property, which it typically is); therefore, you can add a style for TextBlock inside the Label like so:
<Label
Content="_Content Text:"
Target="{Binding ElementName=MyTargetControl}">
<Label.Resources>
<Style TargetType="TextBlock">
<Setter Property="TextWrapping" Value="Wrap" />
</Style>
</Label.Resources>
</Label>
<CheckBox x:Name = "MyTargetControl" />
This way you get to keep the functionality of a Label whilst also being able to wrap the text.
You can put a TextBlock inside the label:
<Label>
<TextBlock Text="Long Text . . . ." TextWrapping="Wrap" />
</Label>
To wrap text in the label control, change the the template of label as follows:
<Style x:Key="ErrorBoxStyle" TargetType="{x:Type Label}">
<Setter Property="BorderBrush" Value="#FFF08A73"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Foreground" Value="Red"/>
<Setter Property="Background" Value="#FFFFE3DF"/>
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Padding" Value="5"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Top"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Label}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true" CornerRadius="5" HorizontalAlignment="Stretch">
<TextBlock TextWrapping="Wrap" Text="{TemplateBinding Content}"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Instead of using a Label class, I would recommend using a TextBlock. This allows you to set the TextWrapping appropriately.
You can always do:
label1.Content = new TextBlock() { Text = textBox1.Text, TextWrapping = TextWrapping.Wrap };
However, if all this "label" is for is to display text, use a TextBlock instead.
Label label1 = new Label() { Content = new TextBlock() { Text = caption, TextWrapping = TextWrapping.Wrap }, FontWeight = FontWeights.Normal };We need to put some kind of control that can wrap text like textblock/textbox
<Label Width="120" Height="100" >
<TextBlock TextWrapping="Wrap">
this is a very long text inside a textblock and this needs to be on multiline.
</TextBlock>
</Label>
try use this
lblresult.Content = lblresult.Content + "prime are :" + j + "\n";
<Label x:Name="datetimeofmsg"
HorizontalAlignment="Left" Margin="4.286,55,0,0"
VerticalAlignment="Top" Background="{x:Null}"
FontWeight="Bold" Width="61.714" Height="20" Foreground="White">
<Label.Content>
<AccessText TextWrapping="Wrap"/>
</Label.Content>
</Label>
I used this to retrieve data from MySql Database:
AccessText a = new AccessText();
a.Text=reader[1].ToString(); // MySql reader
a.Width = 70;
a.TextWrapping = TextWrapping.WrapWithOverflow;
labels[i].Content = a;
Try my version
<Label x:Name="myLabel">
<TextBox FontSize="20" FontWeight="Bold" Background="Transparent" BorderBrush="Transparent"
IsReadOnly="true" TextWrapping="Wrap" HorizontalAlignment="Center" Focusable="False"
Foreground="{Binding Foreground, ElementName=myLabel}"
Text="longMeeeeessssagggeeeeeeeeeeeeeeeeeeeeeeeeeee_Ooooooooeeeeeeeeeee" />
</Label>
Not necessary to use ScrollViewer control.
Something else to keep in mind is parent containers, <Grid/> and what not. Impacted <ColumnDefinition/> needs to be adjusted accordingly, or the wrapping has no effect.
<Grid>
<Grid.ColumnDefinitions>
<!-- auto prohibits wrapping -->
<ColumnDefinition Width="auto" />
<!-- whereas the Kleene star allows wrapping -->
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
</Grid>
