We would like to inform that bindingContext of Header & Footer value of OuterListView will be ViewModel. Based on the reported query and shared code snippet we have prepared the model sample which binds Header & Footer template of OuterListView properly. We have attached the model sample for your reference, please find the sample from below. 
 
 
Meanwhile, please know in detail about the NestedListView behavior and its limitation from below UG: 
 
 
We suspect there must be sample level mistake in your application. Can you please check with the above sample whether the reported issue occurs in our sample also. If no please revert us back with the issue replicated sample if possible so that we can debug and share the exact details for the cause of this issue with possible workaround or confirm you whether it is a defect at our end.

Hi Amer,  
   
Thank you for your patience. 

We have partially fixed the mentioned issue with SfListView and the issue fix has been included in our latest weekly nuget update version 17.3.0.21 and is available for download (nuget.org). But still the issue occurs when adding SfListView inside SfPullToRefresh and we have fixed the related cases with NavigationDrawer and ListView.

We have modified your sample without PullToRefresh and all cases works fine. Please find the sample by the following link,

Sample link:https://www.syncfusion.com/downloads/support/directtrac/general/ze/sfListView_Sample-641653125.zip 

We have commented the SfPullToRefresh related codes in the sample and updated SfListView to version 17.3.0.21. 

Please check the sample and let us know whether it’s resolves the issue in your scenario.
We are working on the issue fix with the PullToRefresh and we will include the complete changes in our weekly nuget release which will be available on November 12, 2019. We appreciate your patience until then.

Subburaj Pandian V

Hi Amer, 


Sorry for the inconvenience caused.

We would like to inform you that Sflistview by default works properly in your sample in which we have removed all other layouts like grid, stacklayout loaded inside the outer listview's ItemTemplate and checked the shared template. Currently, we are validating what exactly causes the reported issue. We will validate and update you further details on 12 November 2019. We will appreciate your patience until then.

Regards,
Gnana Priya N

Hi Amer, 

Thank you for your patience.

We have analyzed and the mentioned issue occurs because of loading ListView in multiple layouts like Grid->Stack->Stack->Grid->Stack->InnerListview inside ItemTemplate which causes the reported issue by preventing touch interaction to inner ListView. This is not related to SfListView and issue occurs in all the Xamarin framework elements including ListView.

Therefore, we have removed some unwanted and empty Layouts in the application and attached the modified sample. Please refer the sample and also attached a screenshot of removed layouts from the following link.



We hope this helps. Please let us know if you need any further assistance.


Regards,
Gnana Priya N
