Simply set HorizontalContentAlignment="Stretch" on your button. The default is centre.

Then a grid with HorizontalAlignment="Stretch" will do what you want.

I think that is what you are asking:

 <Button>
      <StackPanel Orientation="Horizontal">
        <Image src=""/>
        <TextBlock Text="ClickMe"/>
      </StackPaenl>
    </Botton>

If you are using Grid as your container, then you need to define Grid Columns and place the image in column 0 , and the text in column 1. Easier to use Stackpanel in this case.

For example:

  <Button>
    <Grid HorizontalAlignment="Left">
       <Grid. ColumnDefinitions >
          <ColumnDefinition Width="Auto"/>
          <ColumnDefinition Width="Auto"/>
       </Grid. ColumnDefinitions>
                <Image Source="/HomePageDes;component/Images/main_news.png" Height="80" HorizontalAlignment="Left"  Grid.Column="0"/>
                 <TextBlock Text="News"  Grid.Column="1"/>
     </Grid>
   </Button>
