Hi Jay,
1. In EditControl the ContextChoice support allows you to create popups for displaying a list of options. The context choice displaying characters are specified in the configuration file using the DropContextChoiceList attribute in the lexem for the corresponding character. If you wish to display the ContextChoice dropdown in response to period (".") or comma (",") being typed, use XML code as shown below:
lexem BeginBlock="." Type="Operator" DropContextChoiceList="true"
lexem BeginBlock="," Type="Operator" DropContextChoiceList="true"
I have attached a sample that illustrates this.
CS.zip Documentation on ContextChoice can be found at the link given below

Thank you for using Syncfusion products.
