I would like to stretch a listbox similar to that :

<Grid Background="#FFC0BBBB">
        <Grid.RowDefinitions>
            <RowDefinition Height="50" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Border HorizontalAlignment="Stretch" Grid.Row="0">
            <ListBox  Name="listBox"   >
                <ListBoxItem >
                    <StackPanel>
                        <TextBlock Text="Toto"></TextBlock>
                        <!--<Image Source ="" Visibility="Collapsed" />-->
                    </StackPanel>
                </ListBoxItem>
                <ListBoxItem >listbox item 2</ListBoxItem>
                <ListBoxItem >
                    <Grid>
                    <TextBlock Text="Tata"></TextBlock>
                    <Image Source ="" />
                    </Grid>
                </ListBoxItem>
                <ListBoxItem >
                    <Grid>
                        <TextBlock Background="Aqua" Text=""></TextBlock>
                        <Image Source ="https://support.twitter.com/images/twitter-bird.png?1339467554" />
                    </Grid>
                </ListBoxItem>
                <ListBoxItem >
                    <Grid>
                        <TextBlock Text="Vava"></TextBlock>
                        <Image Source ="" />
                    </Grid>
                </ListBoxItem>
            <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <UniformGrid Columns="5" Background="Pink" HorizontalAlignment="Stretch" />
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>               
             </ListBox>
        </Border>
</Grid>

If you put just content like for the second item it works perfectly, but my "real" ListBox will be bind and for some items I need to put an Image for others a TextBlock (I neved need Image+Textblock). I think that I will have to use a converter but I don't know "where" to put it and what should he returns.

Any ideas ? Thanks

If you are binding to data, and then using properties of your data to work out what kind of control you'll need in your ListBoxItem, then you need to use a DataTemplateSelector
