Hello Simon,
The BindingContext of the GroupHeaderTemplate gives you everything you need for that group. Please visit the RadListView GroupHeaderTemplate tutorial for a list of all the properties of the context.
You can use an IValueConverter or DataTriggers in there if you want to do different things based on the group's values.
For example , let's say you wanted to change the text color based on what the group's Key is
public class MyGroupHeaderTextColorConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (value is Telerik.XamarinForms.DataControls.ListView.GroupHeaderContext context)
{
var headerText = context.Key.ToString();
switch (headerText)
{
case "Dairy":
return Color.Gold;
case "Bakery":
return Color.SandyBrown;
case "Meats":
return Color.IndianRed;
}
}
return Color.Black;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}You use that converter like any converter:
If you're trying to hide the header entirely, you could try making the height smaller and not have any elements in there, but that will not completely make it go away because the group header is a fundamental part of the infrastructure.
