    I'm trying to make a TKDataFormDatePickerEditor to load with an empty date field but the TKDataFormDatePickerEditor always shows today date. Here's what I'm doing in the UpdateEditor method after setting the value candidate to null.
    if (property.Name == "StartDate") {
      if (this.ownerVC.dataSource ["StartDate"].ValueCandidate == null) {
        ((TKDataFormDatePickerEditor)editor).EditorValueLabel.Text = string.Empty;

    Hello, Jon,

    Thank you for contacting us.

    To show an empty string as text to the editor value label when the value candidate is null you should use the hintText property of TKEntityProperty. Consider the code snippet:
    public override void ViewDidLoad ()
        base.ViewDidLoad ();
        this.dataSource ["DateOfBirth"].HintText = string.Empty;

    Another option is to implement SetupEditor method and use the Placeholder property of TKDataFormDatePickerEditor:
    public override void SetupEditor (TKDataForm dataForm, TKDataFormEditor editor, TKEntityProperty property)
        if (property.Name == "DateOfBirth") {
            ((TKDataFormDatePickerEditor)editor).Placeholder = string.Empty;

    I hope this helps. If you have further questions, feel free to contact us again.
