wpf height and width by element binding

Question

wpf height and width of control based on rowheight and rowwidth of grid by element binding to it.

 <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="170" />
            <RowDefinition Height="*"   x:Name="ContentControlRow"/>
            <RowDefinition Height="170"/>
        </Grid.RowDefinitions>
        <TabControl Grid.Row="1" x:Name="Tab" MaxHeight="{Binding   ElementName=ContentControlRow, Path=ActualHeight}" Background="Red" VerticalAlignment="Stretch">
            <TabItem>
            </TabItem>
        </TabControl>
    </Grid>

In the above code it is taking MaxHeight=0. But what i need is it should take that based on ContentControlRow's Height and it should be variable based on Window size.

set Path=Height instead of ActualHeight – Swapnil Jan 25 '18 at 04:55 — Swapnil, Jan 25 '18 at 04:55

Change ActualHeight to Height in Binding.

<Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="170" />
            <RowDefinition Height="*"   x:Name="ContentControlRow"/>
            <RowDefinition Height="170"/>
        </Grid.RowDefinitions>
        <TabControl Grid.Row="1" x:Name="Tab" MaxHeight="{Binding   ElementName=ContentControlRow, Path=Height}" Background="Red" VerticalAlignment="Stretch">
            <TabItem>
            </TabItem>
        </TabControl>
</Grid>
