    @"Abdul.3549" It's not straight forward in Android as the Entire datepicker dialog is created internally, you can use reflection to achieve it but the entire Forms control flow will get changed. I can share some test code which i've tried

    [assembly: ExportRenderer(typeof(DatePicker), typeof(CustomDatePickerRenderer))]
    namespace XamarinFormsMaps.Droid
        public class CustomDatePickerRenderer : DatePickerRenderer
            private DatePickerDialog datePickerDialog;
            protected override void OnElementChanged(ElementChangedEventArgs<DatePicker> e)
                this.Control.Click += Control_Click;
            private void Control_Click(object sender, EventArgs e)
                var picker = typeof(DatePickerRenderer);
                var triggerMehotd = picker.GetMethod("OnTextFieldClicked", BindingFlags.NonPublic);
                triggerMehotd.Invoke(this, null);
                var fieldInfo = picker.GetField("_dialog", BindingFlags.NonPublic);
                datePickerDialog = (DatePickerDialog)fieldInfo.GetValue(this);
                // OK button click
                datePickerDialog.GetButton(-1).Click += CustomPageRenderer_Click;
            private void CustomPageRenderer_Click(object sender, EventArgs e)

    thanks @DK90 for replying.

    Reflection is not working fine here, triggerMehotd and fieldInfo returns always null.

    picker.GetMethod("OnTextFieldClicked", BindingFlags.NonPublic | BindingFlags.Instance); Use this line.

    Hi @Abdul.3549

    How you did this in iOS? I would appreciate for a tiny code snippet.

    Cheers Philipp
