I am using Telerik's RadAutoComplete for having an autocomplete field. It is working fine with static data but on the basis of input received by user in autocomplete field, I have to execute the API and fetch data from there. List received in API response will be visible in autocomplete's suggestion view.
As soon as I am assigning my response to the ItemSource of RadAutoComplete, the text entered in the autocomplete is getting reset. For example: If I want to search "Friday", I entered "Fr" in autocomplete field. After receiving the response from the API that "Fr" will be removed from the autocomplete automatically and autocomplete text will be "".
XAML:
<telerikInput:RadAutoComplete
BorderColor="LightGray"
FilteredItemsChanged="autoCompleteUsers_FilteredItemsChanged"
ItemsSource="{Binding UserList}"
SearchThreshold="3"
ShowSuggestionView="True"
SuggestionItemSelected="autoCompleteUsers_SuggestionItemSelected"
TextSearchPath="Name">
<telerikInput:RadAutoComplete.SuggestionItemTemplate>
<DataTemplate>
<StackLayout HeightRequest="20">
<Label
Margin="2"
HorizontalOptions="Start"
Text="{Binding Item.Name}"
TextColor="Black"
VerticalOptions="Center" />
</StackLayout>
</DataTemplate>
</telerikInput:RadAutoComplete.SuggestionItemTemplate>
</telerikInput:RadAutoComplete>
Event
void autoCompleteUsers_FilteredItemsChanged(System.Object sender, Telerik.XamarinForms.Input.AutoComplete.FilteredItemsChangedEventArgs e)
{
var searchedText = (sender as RadAutoComplete).Text;
viewController.GetUserList(searchedText);
}
public async Task GetUserList(string searchedText)
{
// **reassigning userList with the response of API**
UserList = await _APIservice.GetUsers(searchedText);
}
CodePudding user response：
Try using RadAutoCompleteView, it is recommended for Remote search.
