I have this data grid xml code:
Code:
<Window x:Class="SourcicoProjectTest.RecipeListWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="clr-namespace:SourcicoProjectTest.code"
mc:Ignorable="d"
Title="RecipeListWindow" Height="450" Width="800" Loaded="Window_Loaded">
<Window.DataContext>
<local:MainMVVM/>
</Window.DataContext>
<Window.Resources>
<local:RecipeCountConverter x:Key="countConverter"/>
</Window.Resources>
<Grid>
<DataGrid Margin="5, 5, 5, 5"
SelectedItem="{Binding selectedRecipe}"
ItemsSource="{Binding recipesList}"
IsReadOnly="True"
AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Recipe ID"
Binding="{Binding ID}" />
<DataGridTextColumn Header="Recipe Name"
Binding="{Binding name}" />
<DataGridTextColumn Header="Recipe Source"
Binding="{Binding source}" />
<DataGridTextColumn Header="Num. of Ingredients"
Binding="{Binding Path=ingredients.Count}" />
<DataGridTextColumn Header="Ingredients"
Binding="{Binding Path=ingredients}" />
<DataGridTextColumn Header="Prep. Time"
Binding="{Binding prepTime}" />
<DataGridTextColumn Header="Prep. Instructions"
Binding="{Binding prepInstructions}" />
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Content="Details"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Content="Delete"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
</Grid>
</Window>
which is code for a window I am showing.
If you see, the selected item is of type Recipe which has a list of ingredients:
Code:
ObservableCollection<Ingredient> ingredients
I want in one column to display ingredients.Count which is how many ingredients arecipe has.
I tried with this but it shows 0:
Code:
<DataGridTextColumn Header="Num. of Ingredients"
Binding="{Binding Path=ingredients.Count}" />
What do I miss in my XAML code? Do I need to use ValueConverter class/interface to get the count from my list of ingredients?
