If you want to extend and compress the height and Width of your Usercontrol then make the Parent Controls Height="*" and Width="*" and don’t assign any height and width to your controls present inside UserControl. Something like:

<Grid Margin="4" Background="Orange">    
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="50"/>
        <ColumnDefinition Width="*"/>    
    </Grid.ColumnDefinitions>    
    <StackPanel Grid.Column="0">    
        <TextBlock Text="It is fixed" Margin="1"/>       
        <Button Content="It is fixed"/>    
    </StackPanel>    
    <StackPanel Grid.Column="1">    
        <TextBlock Text="It is variable" Margin="1"/>    
        <Button Content="It is fixed" Margin="2"/>    
    </StackPanel>    
</Grid>
