Bonjour,

voilà j'ai une page XAML divisée en 2 Grid. Celui de gauche contient un expander qui fait que lorsqu'on clique sur un bouton le grid de gauche rétrécit.

Je voulais savoir comment faire pour que le grid de droite s'agrandisse automatiquement quand le grid de gauche rétrécit.....et inversement, que le grid de droite rétrecisse quand celui de gauche s'agrandit....En gros comment fait-on un redimensionnement automatique de grid en XAML....
merci

Tu pourrais me montrer un exemple de code que tu utilises, pour que je puisses faire quelques tests histoire de voir si je trouve une solution à ton pb ?

Bien sur

Ca c'est mon code qui est dans ma page principal

Code :

<Grid x:Name="Global" Width="950" Height="550" Background="White" Grid.ColumnSpan="2" Margin="10">
  <Grid x:Name="MenuGauche">
    <Expander HorizontalAlignment="Left" x:Name="expanderLeft" IsExpanded="True" 
              Template="{StaticResource menuGauche}">
      <Canvas Name="canvasMenu" Width="130" Height ="550" Background="Lavender" Opacity=".5">
        <Rectangle Name="lb1" Height="150" Width="120" Fill="White" RadiusX="4" RadiusY="4" 
                   HorizontalAlignment="Center" Margin="5"/>
        <Rectangle Name="lb2" Height="385" Width="120" Fill="White" RadiusX="4" RadiusY="4" 
                   HorizontalAlignment="Center" Margin="5,160,0,5"/>
      </Canvas>
    </Expander>
  </Grid>
  <Grid x:Name="Tab">
    <TabControl Name="tabControl" HorizontalAlignment="Right"  VerticalAlignment="Bottom" Width="795" Height="500" 
                MouseLeftButtonUp="NewOnglet" Background="#F0FAFF">
    </TabControl>
  </Grid>

Et si ça t'intéresse voilà le code qui permet de redéfinir l'Expander:
