NullReferenceException when using SfTextInputLayout

Thread ID:

Asked On March 7, 2019 07:11 PM UTC


I'm using the SfDataForm control and I want to create a custom editor with .SfTextInputLayout.
However, I always get a NullReferenceException when I try to show the editor.
I have created two other editors based on SfRating and SfComboBox before and they are working fine.
This is some basic code I'm using to show the input:

  public class DataFormVideoEditor : DataFormEditor<SfTextInputLayout>

        public DataFormVideoEditor(SfDataForm dataForm) : base(dataForm)

        protected override SfTextInputLayout OnCreateEditorView(DataFormItem dataFormItem)
            SfTextInputLayout inputLayout = new SfTextInputLayout();
            inputLayout.Hint = "Name";
            inputLayout.EnablePasswordVisibilityToggle = true;
            inputLayout.InputView = new Entry() { Text = "John" };
            return inputLayout;

Why does the application crash when I use the SfTextInputLayout?
Do I do something wrong or is the control not supported?

Hi Tamara, 
Thank you for contacting Syncfusion support. 
We have analyzed the reported behavior “NullReferenceException occurs while using SfTextInputLayout as custom editor” as of now dataform supports only views as a custom editor, but we have already implemented feature to support for Layout as a custom editor, and it will be included in our upcoming Volume 1 release, which is expected to roll out at the mid of March 2019. We appreciate your patience until then.
