custom-model-collection-in-.net-maui-aiassistview

This demo demonstartes support for binding collection of custom data objects through the ItemsSource property and allows users to use their own data objects with the control. The ItemsSource property binds a collection of custom data objects to the SfAIAssistView and each item in the collection will be converted to an AssistItem and displayed in the view.

AssistItemConverter :

    public class AssistItemConverter : IAssistItemConverter
    {
        public IAssistItem ConvertToAssistItem(object customItem, SfAIAssistView assistView)
        {
            var assistItem = new AssistItem();
            var item = customItem as ItemModel;
            if (item != null)
            {
                assistItem.Data = item;
                assistItem.IsRequested = item.IsRequested;
                if (item.IsRequested)
                {
                    if (item.Prompt != null)
                    {
                        assistItem.Text = item.Prompt;
                    }
                }
                else
                {
                    if (item.Response != null)
                    {
                        assistItem.Text = item.Response;
                    }
                }
            }
            return assistItem;
        }

        public object ConvertToData(object assistViewItem, SfAIAssistView assistView)
        {
            var item = new ItemModel();
            var assistItem = assistViewItem as AssistItem;
            if (assistItem != null)
            {
                item.IsRequested = assistItem.IsRequested;
                if (item.IsRequested)
                {
                    item.Prompt = assistItem.Text;
                }
                else
                {
                    item.Response = assistItem.Text;
                }
            }
