Ah, I got it working thank you!

I love you plugins they are so well done!

I'll need full code. Here's grouping example:

https://github.com/daniel-luberda/DLToolkit.Forms.Controls/blob/master/Samples/DLToolkitControlsSamples/SamplesFlowListView/GroupingPage.xaml

[ryanherman]

In my XAML I have:
<controls:FlowListView Grid.Row="2" FlowColumnCount="1" SeparatorVisibility="None" HasUnevenRows="true" x:Name="ProjectFlow" BackgroundColor="Transparent" FlowUseAbsoluteLayoutInternally="True" IsGroupingEnabled="True"> </controls:FlowListView>

in my Code I have
` private void LoadEvents(MessageHelper arg)
{
if (App.IotaConnect.isConnected() == false)
{
UserDialogs.Instance.Alert(AppResource.NoInternet, AppResource.NoInternetTitle,
AppResource.OK);
return;
}

        ProjectFlow.FlowColumnTemplate = new FlowTemplateSelector();
        ProjectFlow.FlowItemsSource = arg.EventListV2.events;

        LoadTabs(arg);
    }`

My FlowTemplateSelector() is:
` public class FlowTemplateSelector : DLToolkit.Forms.Controls.FlowTemplateSelector
{
DataTemplate _eventCell = new DataTemplate(typeof(EventCellNew));
DataTemplate _celebCell = new DataTemplate(typeof(CelebCell));
DataTemplate _likeCell = new DataTemplate(typeof(LikeCell));

    protected override DataTemplate OnSelectTemplate(object item, int columnIndex, BindableObject container)
    {
        var type = item.GetType();
        if(type == typeof(ProjectById.Event))
        {
                return _eventCell;
        }

        if (type == typeof(FanBase.Event))
        {
            return _celebCell;
        }

        return _eventCell;
    }
}`

But I put a breakpoint on var type = item.GetType(); and it never gets to it. If I put False for IsGroupingEnabled it will hit the breakpoint.

You are missing FlowGroupDisplayBinding="{Binding Key}"

[ryanherman]

I had it in there and it was still not hitting the template selector.
<controls:FlowListView Grid.Row="2" FlowColumnCount="1" SeparatorVisibility="None" HasUnevenRows="true" x:Name="ProjectFlow" BackgroundColor="Transparent" FlowUseAbsoluteLayoutInternally="True" IsGroupingEnabled="True" FlowGroupDisplayBinding="{Binding Key}" FlowGroupShortNameBinding="{Binding Key}"> </controls:FlowListView>

[daniel-luberda]

Does your model have a valid Key property? You can clone repo and test sample project to see what is missing or put your code there.

[daniel-luberda]

Great, nice that you worked it out :)
