I have followed the instructions below to programmatically set the width of the autocomplete popup.


Unfortunately, this only sets the size of the popup, and not the size of the control within the popup that is actually displaying the results.
I have attached an image to demonstrate this, but even your example exhibits the same problem, which is why the items are displayed in the centre of the popup!

Hi James, 
Thanks for using Syncfusion product. 
We have checked the reported problem in our end and you can resolve this issue by setting the width of the ListBox. Please refer the below code snippet below. 
void auto1_Loaded(object sender, RoutedEventArgs e) 
     Popup pop = AutoComplete1.Template.FindName("PART_Popup", AutoComplete1) as Popup; 
     ListBox listBox = AutoComplete1.Template.FindName("PART_Container", AutoComplete1) as ListBox; 
     if (pop != null) 
         pop.Width = 210; 
         listBox.Width = 200; 
And also please find the screenshot and modified sample regarding it below: 
Let us know whether this helps also if you need any further assistance on this.
