Large dataset require filter after first three letters entered

[David]

Hi, I use both Telerik and yourself but Telerik has a limitation in that its every character it is going back to the result set for auto-complete.

I am wanting to only kick off a search after the first 3 characters have been entered is that at all possible.

I.e it won't perform a search till it is at the 3rd letter, as this appeas to be the only way I can get their data set down small enough for the maxjson limit of mvc api.

Hi David, 

 

We have analyzed the requirement “Large dataset require filter after first three letters entered” in SfAutoComplete. We can achieve this requirement by using the MinimumPrefixCharacters property in SfAutoComplete as per the below code snippet.  

 

Code snippet: 

<StackLayout  

        VerticalOptions="Start"  

        HorizontalOptions="Start" 

        Padding="30"> 

        <autocomplete:SfAutoComplete x:Name="autoComplete" MinimumPrefixCharacters="3" 

                                     HeightRequest="40"> 

            <autocomplete:SfAutoComplete.AutoCompleteSource> 

                <ListCollection:List x:TypeArguments="x:String"> 

                    <x:String>India</x:String> 

                    <x:String>Uganda</x:String> 

                    <x:String>Ukraine</x:String> 

                    <x:String>Canada</x:String> 

                    <x:String>United Arab Emirates</x:String> 

                    <x:String>France</x:String> 

                    <x:String>United Kingdom</x:String> 

                    <x:String>China</x:String> 

                    <x:String>United States</x:String> 

                    <x:String>Japan</x:String> 

                    <x:String>Angola</x:String> 

                </ListCollection:List> 

            </autocomplete:SfAutoComplete.AutoCompleteSource> 

        </autocomplete:SfAutoComplete> 

    </StackLayout>
