Item index of Binding element
- by vibeeshanRC
I am creating a XAML / C# WinRT App and i have a collection of collection and i am binding it to a Grid-view(collections as groups )
Now i have to color the background of the GridViewItem according to their index in the collection (Dark color for the first one and light color for the last one ) How can i implement using a converter. (if there are 6 collections with 10 items all the first item will the dark and the 10 the item will be lighter).
Simply: How can i send the item-index property to the converter as a parameter.
My XAML
<GridView x:Name="Grid1" ItemsSource="{Binding}"
ItemTemplateSelector="{StaticResource templateSelector}"
SelectionMode="None" >
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel Orientation="Horizontal" VirtualizingStackPanel.VirtualizationMode="Recycling"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.GroupStyle>
<GroupStyle HidesIfEmpty="True">
<GroupStyle.HeaderTemplate>
<DataTemplate>
<Grid Margin="0,0,0,0">
<TextBlock Text='{Binding Name}'
Margin="5" />
</Grid>
</DataTemplate>
</GroupStyle.HeaderTemplate>
<GroupStyle.ContainerStyle>
<Style TargetType="GroupItem" >
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Margin" Value="0,0"/>
</Style>
</GroupStyle.ContainerStyle>
<GroupStyle.Panel>
<ItemsPanelTemplate>
<VariableSizedWrapGrid/>
</ItemsPanelTemplate>
</GroupStyle.Panel>
</GroupStyle>
</GridView.GroupStyle>
</GridView>
..........
<converters:MyConverter x:Key="templateSelector"
Temp1="{StaticResource Temp1}"
Temp2="{StaticResource Temp2}"
>
</converters:MyConverter>
<DataTemplate x:Key="Temp1">
<Grid >
<Grid>
<Grid.Resources>
<converters:PanelBackgroundColorConverter x:Name="panelBackgroundColorConverter" Key="{Binding}"/>
<Grid.Resources/>
<Grid.Background>
<Binding Path="MPath" Converter="{StaticResource panelBackgroundColorConverter}" ConverterParameter="sym"/>
</Grid.Background>
<Grid/>
<DataTemplate/>
