Keyboard Flags and Selected Item Issue

[Nic]

Hi All,

I have a couple of issues with SfAutoComplete using Xamarin forms MVVM both are with Android, they work fine in iOS.

I have set some keyboard flags when the SfAutoComplete gets focus to change from Capitalize Words to Capitalize Charactors depending a boolean that is user defined.

this work fine with iOS but on Android it does not take effect, it does work fine if used with an entry.

Also again on Android randomly when using SfAutoComplete if the dropdown is populated but the final word is not in the list or selected from the row of words above the keyboard the app crashes with an index error.

Any help please.

Hi Nic, 

 

Greetings from Syncfusion.  

 

Query 1: When the SfAutoComplete gets focus to change from Capitalize Words to Capitalize Characters. 

 

We have analyzed the requirement from our side. You can achieve this by using the custom renderer for the SfAutoComplete. We have prepared the simple sample for your reference. Please try the attached below sample and let us know if you have any concern on this. 

 

Code Snippet: 

public class CustomRendererAndroid : SfAutoCompleteRenderer 

    { 

        public CustomRendererAndroid() 

        { 

        } 

        protected override void OnElementChanged(ElementChangedEventArgs<Syncfusion.SfAutoComplete.XForms.SfAutoComplete> e) 

        { 

            base.OnElementChanged(e); 

            if (Control != null) 

            { 

                Control.FocusChanged += Control_FocusChanged; 

            } 

        } 

        private void Control_FocusChanged(object sender, Com.Syncfusion.Autocomplete.FocusChangedEventArgs e) 

        { 

            if (e.HasFocus) 

            { 

                if (Control != null) 

                { 

                    Control.InputType = Android.Text.InputTypes.TextFlagCapCharacters; 

                } 

            } 

        } 

    } 

 

Query 2:Selected from the row of words above the keyboard the app crashes with an index error.

Hi Muneesh,

Thank you very much for the Android renderer it works perfectly,

to keep thinks all nice and tidy i would like to use the renderer for iOS but i am stuck with the control type i looked at your sample but have not been able to work out what goes after the Control.

Control.<what goes here> = UITextAutocapitalizationType.AllCharacters;

After creating the Android renderer i have not had the app crash, so must have been something in my code.

Regards

Nic

Hi Muneesh,

I've sorted the iOS renderer as below:

var editText = Control.TextField as UITextField;

 editText.AutocapitalizationType = UITextAutocapitalizationType.Words;

thanks for you help.

Nic
