<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="10"/>
<RowDefinition Height="45"/>
<RowDefinition Height="160"/>
<RowDefinition Height="50"/>
<RowDefinition Height="15"/>
<RowDefinition Height="272*"/>
</Grid.RowDefinitions>
<Button Grid.Row="1" x:Name="btnCreationOffre" Background="Transparent" Width ="120" Height="35" BorderBrush="{x:Null}" HorizontalAlignment="Left" Click="btnCreationOffre_Click" Margin="0,2,0,8" Style="{DynamicResource nv_offreButton}"/>
<Button Grid.Row="1" x:Name="btnModifierOffre" Background="Transparent" Width ="120" Height="35" BorderBrush="{x:Null}" HorizontalAlignment="Left" Click="btnModifierOffre_Click" Margin="130,2,0,8" Style="{DynamicResource modifierButton}" />
<Button Grid.Row="1" x:Name="btnConsulterOffre" Width ="120" Height="35" Content="Consulter" HorizontalAlignment="left" Click="btnConsulterOffre_Click" Margin="260,2,0,8" Style="{DynamicResource consulterButton}" />
<Button Grid.Row="1" x:Name="btnSuppOffre" Background="Transparent" Width ="120" Height="35" BorderBrush="{x:Null}" HorizontalAlignment="Left" Click="btnSuppOffre_Click" Margin="390,2,0,8" Style="{DynamicResource suppButton}" />
<Rectangle HorizontalAlignment="Stretch" Fill="Gray" Height="2" Grid.Row="1" VerticalAlignment="Bottom" Grid.ColumnSpan="4" />
<Grid x:Name="gridFocus" Grid.Row="2" Grid.ColumnSpan="4">
<TextBlock Grid.Row="0" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Center">Numéro offre</TextBlock>
<TextBox x:Name="textBoxNumOffre" Height="30" Grid.Row="0" Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Center" />
