Hi Michael,
Thanks for your interest in Syncfusion products.
You can achieve your requirement by enabling the EditControl's 'FilterAutoCompleteItems' property. this property will Filters the item in the AutoComplete Context choice and the filtered item alone will be visible. For more information i have included the sample as follows.
[Code Snippet]
this.editControl1.FilterAutoCompleteItems = true;
