Option to add loading while loading the suggestion

[Ajith Gopalakrishnan]

Hi

I am currently working on a screen in which we are having a  auto compelete which fetches the data remotely currently I am facing 2 problems there

a)The user enters the text according to which the suggestion are fetched remotely over a internet currently there is bit delay in getting the data for that time being 

"No record found" is shown Is there a option to show loading message there

b) The Suggestions are returned based on some matching done remotely here the autocomplete performs it's filtering too, I have seen filtering modes like contains, begins with, ends, custom etc. How can we avoid the filtering by autocomplete.

Thanks in advance for the help

Hi Ajith Gopalakrishnan, 

  

Greetings from the Syncfusion. 

  

Query 1: “Is there an option to show loading message” 

  

We have checked the reported query and we have achieved your requirement using DropDownHeaderView as in below: 

  

Code Snippet: 

  

 

<autocomplete:SfAutoComplete.DropDownHeaderView> 

                <StackLayout Orientation="Horizontal" > 

                    <Label Text="Loading" VerticalTextAlignment="Center" HorizontalOptions="Center" VerticalOptions="Center"/> 

                    <ActivityIndicator IsRunning="True" /> 

                </StackLayout> 

</autocomplete:SfAutoComplete.DropDownHeaderView> 

 

 

private void autoComplete_FilterCollectionChanged(object sender, Syncfusion.SfAutoComplete.XForms.FilterCollectionChangedEventArgs e) 

{ 

            if ((sender as SfAutoComplete).FilteredItems.Count() > 0) 

            { 

                autoComplete.ShowDropDownHeaderView = false; 

            } 

            else 

            { 

                autoComplete.ShowDropDownHeaderView = true; 

            } 

 }

Query 2: “How can we avoid the filtering by autocomplete” 

  

This can be achieved by setting the Suggestionmode to custom and return false to the Filter items as in below: 

  

Code Snippet: 

  

 

autoComplete.Filter = AvoidFilter; 

 

public bool AvoidFilter(string search, object item) 

{ 

            return false; 

 }
