SfAutocomplete Mvvm Value Changed BInding

Question

HiI am facing some implementation issues of SfAutocomplete and unable to figure out the solution.for my project there we need implementation Autocomplete. Here the suggestion is loaded dynamically according to the user input. Here data fetching need to be started once the user enters more than 3 characters. According to the input server returns the related data. How can we implement the above feature with mvvm(viewmodel).Thanks in advance.Ajit

autocomplete.Filter = FilterSuggestions; 
 
public bool FilterSuggestions(string search, object item) 
{ 
   string text = item.ToString().ToLower(); 
   if (item != null) 
   { 
      try 
      { 
         if (search.Count() > 2) 
         { 
             return true; 
         } 
         else 
         {  
             return false; 
         } 
      } 
      catch (Exception) 
      {

I was wondering whether there is option to initiate search only if the auto complete text length is greater than 3? Like an replacement for valuechanged event in xaml.cs
