Kanban Board crashes when open second time

[Umair Hassan]

Unhandled Exception:

System.ObjectDisposedException: Cannot access a disposed object.

Object name: 'NativeKanbanExt'.

This exception comes. And only happens on iOS. I test it on iPhone 6s. For android it's working fine.

Hi Umair, 

  

We have tried to replicate the reported issue at our end by created a sample with the following scenarios which will cause object disposed exception: 

  

- By navigating between Kanban sample page and MainPage 

- By dynamically removing and adding Kanban control. 

- By dynamically removing and adding Kanban cards. 

  

We are afraid that, we are not able to reproduce the issue at our end. 

  

Please find the sample from the below link.  

Sample: http://www.syncfusion.com/downloads/support/forum/143961/ze/GettingStartedKanban-1430567525 

  

Since we are not aware of your exact application scenario, we were not able to reproduce this issue at our end, so can you please revert us by modifying the sample based on your application along with replication procedure. This will be helpful for us to investigate further and provide you a better solution at the earliest.

Bharathi.

Thanks but i am able to resolve it by adding binding context of SfKanban. This crash will happen if we didn't set binding context.

Hi Umair, 

 

We have tried to replicate the reported issue at our end by creating a sample without setting BindingContext for Kanban and tested in iOS platform. We afraid that, we are not able to reproduce the issue at our end. 

 

Please find the sample from the below link.
