how can i remove space? is there any property for this? or maybe i can do it only manually in xaml? here is all xaml:

<Window x:Class="WPFnotatnik.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <Menu Grid.Row="0">
        <MenuItem Header="File"/>
        <MenuItem Header="Another"/>
    </Menu>
    <Grid x:Name="contentGrid" Grid.Row="1">
        <RichTextBox Name="richTextBox1" HorizontalContentAlignment="Left" />
    </Grid>
</Grid>

Answer 1

This is works: Padding=”-4 0 0 0″

<RichTextBox Name="richTextBox1"
                     HorizontalContentAlignment="Left"
                     Padding="-4 0 0 0" />
