The AutoCompleteBox that is part of Silverlight Toolkit for Windows Phone by default shows the suggestions when you type one character in the AutoCompleteBox .
You can change this behaviour . For example , if you want to display the Suggestions in the Autocompletebox if you type 3 characters or more , you can set the property MinimumPrefixLength to 3 .
How to Set the Minimum Characters for AutoCompleteBox to filter in Windows Phone ?
Assume that the AutocompleteBox has the following List as ItemSource .
public List<string> GetSports() { List<string> Sports = new List<string>(); Sports.Add("Cricket - One Day"); Sports.Add("Cricket - Test"); Sports.Add("Tennis"); Sports.Add("Table Tennis"); Sports.Add("Hockey"); Sports.Add("Football"); return Sports; }
If you Set the MinimumPrefixLength of the AutoCompleteBox to 3 , then you should get the the suggestion only when you type 3 or more characters as shown below
AutoCompleteBox txtbox = new AutoCompleteBox(); txtbox.MinimumPrefixLength = 3; stack.Children.Add(txtbox); // Data txtbox.ItemsSource = GetSports();
If you dont want the AutocompleteBox to show the suggested words , then set the MinimumPrefixLength of AutoCompleteBox to -1 .
