Hi Mahmut,
Thanks for contacting Syncfusion support,
We have checked the reported issue “Pager Buttons are not visible when adding a data at runtime” and we are unable to reproduce the issue in our end and it is working fine as expected. We have attached the tested sample for your reference. In that sample we have added a data to DataPager and PagedSource to ItemSource of SfDataGrid on Button click.
Please check the sample and let us know if you still facing the same issue? If not, please modify the sample based on your scenario and revert us back.
Please let us know the following details.
* SfDataGrid version.
* Xamarin Forms Version.
* Which Platform you are facing the issue.
* Video of the issue.
* Which Collections you are adding to SfDataGrid and SfPager.
* How you link the SfPager with SfDataGrid.
* How you adding the data at runtime.
Regards,
Karthik Raja
