Asked On May 31, 2016 12:24 AM UTC

Hello, I'm currently switching over all of my controls to use the Syncfusion controls and have so far found it very easy to switch. When testing, I discovered that the dropdown can open in an undesirable position, such as either off the screen or with the Ok/Cancel buttons hidden. I've attached a screenshot showing the position of my controls and what it looks like when opened.

Is there a way to force the dropdown to open in full screen mode? This is how my previous control implementation worked and I never had an issue. Thank you!

Hi Matt,

Thank you for using Syncfusion products.

We have checked the reported issue by placing SfDatePicker at bottom and prepared a sample that tries to meet your requirement. In this sample, we have moved the Popup containing SfDateSelector up by setting new top Margin for the popup used in SfDatePicker when BottomAppBar exists. So that BottomAppBar will not hide the popup. You can download the same from the following link:

Thank you. This should work, but hard-coding a margin value seems hacky, especially given different screen sizes the app will need to respond to. Is there a way to force it to open full-screen as in the following screencap?

Ok, I found a solution based on your example. The following will open up a full-width pop-up, centered vertically.

private void picker_Loaded(object sender, RoutedEventArgs e)


if (BottomAppBar != null && picker != null)


foreach (Popup popup in VisualUtils.FindVisualChildrenOfType<Popup>(picker))


if (popup != null && popup.Name == "PART_DropDown")


popup.Width = Window.Current.Bounds.Width;

popup.Height = Window.Current.Bounds.Height;

//popup.Margin = new Thickness(0, -BottomAppBar.Height, 0, 0);




picker.Loaded -= picker_Loaded;
