GridView width inherited from parent

问题:

I have a StackPanel with a fixed width. Inside that StackPanel I have a GridView, which Width should be limited to its parent width (smth like Width="*").

My sample XAML:

<StackPanel Orientation="Horizontal" Width="300" Height="300">
        <TextBox Width="50" Margin="0" Height="50" Background="Blue"></TextBox>
        <GridView >
            <GridView.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapGrid Orientation="Horizontal" FlowDirection="LeftToRight" />
                </ItemsPanelTemplate>
            </GridView.ItemsPanel>
            <GridView.Items>
                <TextBox Width="50" Margin="0" Height="50" Background="Green"></TextBox>
                <TextBox Width="50" Margin="0" Height="50" Background="Green"></TextBox>
                <TextBox Width="50" Margin="0" Height="50" Background="Green"></TextBox>
                <TextBox Width="50" Margin="0" Height="50" Background="Green"></TextBox>
                <TextBox Width="50" Margin="0" Height="50" Background="Green"></TextBox>
            </GridView.Items>
        </GridView>
    </StackPanel>

In this example the GridView width is wider than the parent, so some of its items are not displayed (not wrapped). When I set GridView width to a fixed value items are wrapped, but I can't use fixed value in my project.

In this scenario it's more beneficial to have a Grid rather than a StackPanel. The code below will achieve the desired effect (the GridView will take up any unused space next to the TextBox).

<Grid Width="300" Height="300">
    <Grid.ColumnDefinitions>
    <ColumnDefinition Width="50" />
    <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
            <TextBox Grid.Column="0" Height="50" Background="Blue"></TextBox>
            <GridView Grid.Column="1">
                <GridView.ItemsPanel>
                    <ItemsPanelTemplate>
                        <WrapGrid Orientation="Horizontal" FlowDirection="LeftToRight" />
                    </ItemsPanelTemplate>
                </GridView.ItemsPanel>
                <GridView.Items>
                    <TextBox Width="50" Margin="0" Height="50" Background="Green"/>
                    <TextBox Width="50" Margin="0" Height="50" Background="Green"/>
                    <TextBox Width="50" Margin="0" Height="50" Background="Green"/>
                    <TextBox Width="50" Margin="0" Height="50" Background="Green"/>
                    <TextBox Width="50" Margin="0" Height="50" Background="Green"/>
                </GridView.Items>
            </GridView>
</Grid>

You can try horizontalscrollmode enabled and horizontalscrollbarvisibility to true. But data would not be wrapped.
