The C1AutoComplete control provides instant text suggestions by searching the best possible match for the user input. However, you can change this default behavior and add some time gap between user input and the search. For this, you need to use the Delay property and set time delay in milliseconds.

The following code example shows how you can set time delay in C1AutoComplete.

HighlightDropdown.Delay = TimeSpan.FromSeconds(1.5);
