Hi ASHISH,

Thank you for contacting Syncfusion Support.

We could not reproduce the issue “Object Disposed Exception in SfAutoComplete” in Xamarin.Forms.Android platform. We have prepared a sample for your reference to check this issue, please find the sample from the link given below.

Sample link: http://www.syncfusion.com/downloads/support/directtrac/general/ze/SFAutoComplete_5-1800883168.zip

If the issue still reproduced at your end, please update us with modified sample in which the issue occurs with the replication procedure.

This could help us to provide better solution on this.

Regards,

Selva Kumar V.

This issue happens to me, too, sometimes. So it exists without doubt (SfAutoComplete)
Unfortunately I can't provide a repro project, because the exception seems to be thrown randomly, while typing in the control and the dropdown suggestion list appears / updates.
I will update the thread if I manage to find a way to reproduce the issue exactly.

Hi Tommaso, 

  

Greetings from Syncfusion. 

  

Please take your time and we will wait for your update so that we can eliminate the issue with AutoComplete control as we are not able to reproduce.
