How to a create grid view with a fixed number of columns in UWP?

Question

I'm trying to create a calendar component for my app. Currently I'm working on a calendar view that is meant to show 7 days wide month, where each day is a list of events.

To do so I need to inform GridView that I always want it to be formatted in a way to hold 7 elements in each row without gaps between them. The underlying collection would always contain multiple of seven elements.

What I currently have (ExtendedGridView/ExtendedListView are the same basic GridView/ListView and do not do any visual transformations):

<local:ExtendedGridView  x:Name="gridView" Margin="0"
                             IsSwipeEnabled="True"                                     
                             IsItemClickEnabled="True"
                             SelectionMode="Single"
                             ItemsSource="{Binding GroupCollection}"
                             VerticalAlignment="Stretch"
                             HorizontalAlignment="Stretch">

        <local:ExtendedGridView.DataContext>
            <local:MainViewModel/>
        </local:ExtendedGridView.DataContext>
        <local:ExtendedGridView.Resources>                
            <DataTemplate x:Key="DefaultGridItemTemplate">
                <Grid Width="100*" Height="60*" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
                    <local:ExtendedListView Margin="0"
                                            IsSwipeEnabled="False"
                                            IsItemClickEnabled="True"
                                            ItemsSource="{Binding Group}">
                        <local:ExtendedListView.ItemContainerStyle>
                            <Style
                                TargetType="ListViewItem">
                                <Setter
                                    Property="HorizontalAlignment"
                                    Value="Stretch" />
                                <Setter
                                    Property="VerticalAlignment"
                                    Value="Stretch" />
                            </Style>
                        </local:ExtendedListView.ItemContainerStyle>

                        <local:ExtendedListView.Resources>
                            <DataTemplate x:Key="DefaultInnerListItemTemplate">
                                <TextBlock Text="{Binding Data}" 
                                               FontSize="12" Foreground="Green"/>
                            </DataTemplate>
                        </local:ExtendedListView.Resources>
                        <local:ExtendedListView.ItemTemplate>
                            <Binding Source="{StaticResource DefaultInnerListItemTemplate}"/>
                        </local:ExtendedListView.ItemTemplate>
                    </local:ExtendedListView>
                </Grid>
            </DataTemplate>

            <ItemsPanelTemplate x:Key="DefaultGridPanelTemplate">
                <WrapGrid MaximumRowsOrColumns="7" Orientation="Horizontal" HorizontalChildrenAlignment="Stretch" VerticalChildrenAlignment="Stretch">
                </WrapGrid>
            </ItemsPanelTemplate>
        </local:ExtendedGridView.Resources>
        <local:ExtendedGridView.ItemContainerStyle>
            <Style
                TargetType="GridViewItem">
                <Setter
                    Property="HorizontalAlignment"
                    Value="Stretch" />
                <Setter
                    Property="VerticalAlignment"
                    Value="Stretch" />
            </Style>
        </local:ExtendedGridView.ItemContainerStyle>
        <local:ExtendedGridView.ItemTemplate>
            <Binding Source="{StaticResource DefaultGridItemTemplate}"/>
        </local:ExtendedGridView.ItemTemplate>
        <local:ExtendedGridView.ItemsPanel>
            <Binding Source="{StaticResource DefaultGridPanelTemplate}"/>
        </local:ExtendedGridView.ItemsPanel>
    </local:ExtendedGridView>

How it currently looks:

I'm fairly new to using XAML so maybe I should take a completely different route. Any help and advices are appreciated.

It would be great if you can create multiple visual state for different screen where you need to display this gridview and fix columns width accordingly. you can follow this link
