Thanks for contacting Syncfusion Support.
We have checked your query. If you add the title view and layout the SfDataGrid from top(dataGrid.Frame.Y = 0) in your controller, then the reported issue will occur. However, you can overcome this issue by layout the SfDataGrid after the title view is placed in the viewcontroller. Please refer the below code snippet for better understand.
// In MyViewController.cs
public override void ViewDidLayoutSubviews()
dataGrid.Frame = new CGRect(0,60,this.View.Frame.Width,this.View.Frame.Height);
In the above case, we have set the SfDataGrid’s Y position as 60 in order to SfDataGrid layout after the title view. You can modify the Y value based on your requirement.
We have attached a simple sample for your reference and you can download the same from the below link.
