WIndows Combobox AutoComplete - can you set the duration of typing time?

Question

We use ComboBoxes in our Winforms app with type-ahead functionality enabled (AutoCompleteMode property = Suggest, AutoCompleteSource = ListItems). When the user starts typing, the ComboBox will jump ahead to match what has been typed, as intended. But if the user pauses for a second or two in the middle of their typing, the AutoComplete "resets" and the next character they type will then be used as a new starting point for the autocomplete.

For example, say they type "Bike" - the ComboBox will jump to the "Bikes" entry in the ComboBox. But say they type "Bik", then pause for a few seconds, then type "e" - the ComboBox will forget about the typed "Bik" and jump to the first entry to start with "e".

Our users have expressed a desire to extend the amount of time in which they get to type before it "resets". Does anyone know if there's a way to configure this or code around it?

Looks like this can't be done with the default implementation. Have you seen this : https://stackoverflow.com/questions/11780558/c-sharp-winforms-combobox-dynamic-autocomplete — Sven Bardos, Jan 13 '19 at 23:17

No luck, the IAutoComplete API used by the ComboBox does not have any such option.

You should be able to find out by using .net reflector on the System.Windows.Forms namespace and looking for the control in code.
