I have an issue putting an action button in my ItemRepeater. I proceeded the same way as I do in ListView :
<muxc:ItemsRepeater Margin="0,24,0,0" ItemsSource="{x:Bind ViewModel.Team.Events, Mode=OneWay}">
<muxc:ItemsRepeater.ItemTemplate>
<DataTemplate x:DataType="models:Event">
<controls:Expander
HorizontalContentAlignment="Left"
Header="{x:Bind Name, Mode=OneWay}"
ExpandDirection="Down"
>
<StackPanel HorizontalAlignment="Left" Padding="24">
<TextBlock Text="{x:Bind Name}" FontSize="36" />
<TextBlock Text="{x:Bind Description}" />
<StackPanel Spacing="4" Orientation="Horizontal">
<TextBlock Text="{x:Bind Start}" />
<TextBlock Text="-" />
<TextBlock Text="{x:Bind End}" />
</StackPanel>
<TextBlock Text="{x:Bind Type}" />
<Grid Width="1000" Margin="0,24,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="13*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="13*" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0">
<TextBlock FontSize="24" Text="Participations" />
<ListView ItemsSource="{x:Bind Participations}">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate x:DataType="models:Participation">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="9*" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<TextBlock Text="{x:Bind Username}" />
<FontIcon Grid.Column="1" Glyph="{x:Bind Confirmed, Converter={StaticResource BooleanIconConverter}}"></FontIcon>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackPanel>
<StackPanel Grid.Column="2">
<TextBlock FontSize="24" Text="Discrepancies" />
<Grid Margin="8">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<TextBlock Text="Player" />
<TextBlock Text="Type" Grid.Column="1"/>
<TextBlock Text="Reason" Grid.Column="2"/>
<TextBlock Text="Delay" Grid.Column="3"/>
</Grid>
<ListView ItemsSource="{x:Bind Discrepancies}">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate x:DataType="models:Discrepancy">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<TextBlock Text="{x:Bind Username}" />
<TextBlock Text="{x:Bind Type}" Grid.Column="1"/>
<TextBlock Text="{x:Bind Reason}" Grid.Column="2"/>
<TextBlock Text="{x:Bind DelayLength}" Grid.Column="3"/>
<Button Grid.Column="4" HorizontalAlignment="Right">
<Button.Flyout>
<Flyout>
<StackPanel>
<TextBlock Style="{ThemeResource BaseTextBlockStyle}" Text="Are you sure ?" Margin="0,0,0,12" />
<Button Click="DeleteDiscrepancy" Content="Yes" />
</StackPanel>
</Flyout>
</Button.Flyout>
<StackPanel Spacing="8" Orientation="Horizontal">
<FontIcon Glyph="" />
</StackPanel>
</Button>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackPanel>
</Grid>
<StackPanel Spacing="16" Orientation="Horizontal" FlowDirection="RightToLeft">
<Button Click="HandleClickAddDiscrepancy">
<StackPanel Spacing="8" Orientation="Horizontal">
<TextBlock Text="Add Discrepancy"></TextBlock>
<FontIcon Glyph=""/>
</StackPanel>
</Button>
<Button>
<StackPanel Spacing="8" Orientation="Horizontal">
<TextBlock Text="Edit Event"></TextBlock>
<FontIcon Glyph=""/>
</StackPanel>
</Button>
<Button>
<StackPanel Spacing="8" Orientation="Horizontal">
<TextBlock Text="Delete Event"></TextBlock>
<FontIcon Glyph=""/>
</StackPanel>
</Button>
</StackPanel>
</StackPanel>
</controls:Expander>
</DataTemplate>
</muxc:ItemsRepeater.ItemTemplate>
</muxc:ItemsRepeater>
And in my code-behind :
private void HandleClickAddDiscrepancy(object sender, RoutedEventArgs e) {
var evt = (sender as Button)?.DataContext as Event;
if(ViewModel.AddDiscrepancyCommand.CanExecute(evt)) {
ViewModel.AddDiscrepancyCommand.Execute(evt);
}
}
But in this code-behind method, the DataContext of my button is null. Shouldn't it be the currend element of the list, in which section the button I clicked is ? How should I proceed to implement such feature ? Thanks in advance !
