# customize-the-itemtemplate-unbound-treeview-xamarin

This repository demonstrates how to customize the item template in an unbound Xamarin.Forms TreeView (SfTreeView) control. It provides a sample implementation that shows how to define and style TreeView nodes directly in XAML without data binding, enabling flexible and visually distinct hierarchical layouts.

## Sample

### XAML
```xaml
<ContentPage.Resources>
<ResourceDictionary>
<helper:TextColorConverter x:Key="textColorConverter"/>
</ResourceDictionary>
</ContentPage.Resources>

<StackLayout>
<syncfusion:SfTreeView x:Name="treeView">
<syncfusion:SfTreeView.ItemTemplate>
<DataTemplate>
<Grid>
<Label Text="{Binding Content}" TextColor="{Binding Level, Converter={StaticResource textColorConverter}}" VerticalOptions="Center"/>
</Grid>
</DataTemplate>
</syncfusion:SfTreeView.ItemTemplate>

<syncfusion:SfTreeView.Nodes>
<treeviewengine:TreeViewNode Content="Australia" IsExpanded="True">
<treeviewengine:TreeViewNode.ChildNodes>
<treeviewengine:TreeViewNode Content="New South Wales">
<treeviewengine:TreeViewNode.ChildNodes>
<treeviewengine:TreeViewNode Content="Sydney"/>
<treeviewengine:TreeViewNode Content="Canberra"/>
<treeviewengine:TreeViewNode Content="Newcastle�Maitland"/>
</treeviewengine:TreeViewNode.ChildNodes>
</treeviewengine:TreeViewNode>
<treeviewengine:TreeViewNode Content="Victoria">
<treeviewengine:TreeViewNode.ChildNodes>
<treeviewengine:TreeViewNode Content="Melbourne"/>
</treeviewengine:TreeViewNode.ChildNodes>
</treeviewengine:TreeViewNode>
</treeviewengine:TreeViewNode.ChildNodes>
</treeviewengine:TreeViewNode>
</syncfusion:SfTreeView.Nodes>
</syncfusion:SfTreeView>
</StackLayout>
```

### TextColorConverter
```csharp
public class TextColorConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
var level = (int)value;
if (level == 0) return Color.Red;
else if (level == 1) return Color.Blue;
else return Color.Green;
}

public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
```
