DefaultValue annotations doesn't used for localization.

[Dzianis]

Hello. Could you help me, please?

I don't see DefaultValue annotations for elements of interface.

As example I see "DatePopupButtonToolTip" instead of the annotation [DefaultValue("Open the calendar popup.")]

public class DateTimePicker : RadDateTimePicker
{
    private DateTimePicker.BDDatePickingCalendar _calendar;
    private DateTimePicker.BDRadDateInput _dateInput;

    public override RadCalendar Calendar
    {
        get
        {
            if (_calendar == null)
            {
                _calendar = new DateTimePicker.BDDatePickingCalendar();
            }
            return _calendar;
        }
    }

    public override RadDateInput DateInput
    {
        get
        {
            if (_dateInput == null)
            {
                _dateInput = new DateTimePicker.BDRadDateInput();
            }
            return _dateInput;
        }
    }

    public override DateTime? SelectedDate
    {
        get
        {
            return DateInput.SelectedDate;
        }
        set
        {
            base.SelectedDate = value;
            DateInput.SelectedDate = value;
        }
    }

    private class BDRadDateInput : RadDateInput
    {
        private string GetClientControlType()
        {
            Attribute clientScriptResource = TypeDescriptor.GetAttributes(this)[typeof(ClientScriptResourceAttribute)];
            return ((ClientScriptResourceAttribute)clientScriptResource).ComponentType;
        }

        protected override IEnumerable<ScriptDescriptor> GetScriptDescriptors()
        {
            var descriptor = new DateTimePicker.BDControlScriptDescriptor(GetClientControlType(), ClientID);
            ((IControl)this).DescribeComponent(descriptor);
            return new List<ScriptDescriptor>(new ScriptDescriptor[] { descriptor });
        }
    }

    private class BDDatePickingCalendar : DatePickingCalendar
    {
        private string GetClientControlType()
        {
            Attribute clientScriptResource = TypeDescriptor.GetAttributes(this)[typeof(ClientScriptResourceAttribute)];
            return ((ClientScriptResourceAttribute)clientScriptResource).ComponentType;
        }

        protected override IEnumerable<ScriptDescriptor> GetScriptDescriptors()
        {
            var descriptor = new DateTimePicker.BDControlScriptDescriptor(GetClientControlType(), ClientID);
            ((IControl)this).DescribeComponent(descriptor);
            return new List<ScriptDescriptor>(new ScriptDescriptor[] { descriptor });
        }
    }

    private class BDControlScriptDescriptor : ScriptControlDescriptor, IScriptDescriptor
    {
        public BDControlScriptDescriptor(string type, string elementID)
            : base(type, elementID)
        {
        }

        protected override string GetScript()
        {
            return base.GetScript().Replace(@" ", " ");
        }
    }

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        EnableAjaxSkinRendering = true;
        Calendar.EnableAjaxSkinRendering = true;
        DateInput.EnableAjaxSkinRendering = true;
    }
}

Hello Dzianis,

Thank you for contacting us.

Although that inherited controls are not supported, I have tested the code snippet that you have provided with our latest version and everything is working correctly and the "DatePopupButtonToolTip" is displayed as "Open the calendar popup". Furthermore, I have tested with global resources file and again, no problems occurred. 

If the problem on your side persists, please try with our latest version and see if it will have any difference. If not, please open a regular support ticket and attach a sample, runnable project that replicates the problem, so we can test it locally.

Thank you, Konstantin!

At the moment I resolved the problem by manual translation of values.
I think, the problem can be related with our own global localization mechanism.

Thanks!

As you can see on the screenshot. We have square brackets for the value  "[DatePopupButtonToolTip]". I think our code inject the brackets before your code and your code can't find a needed value. :)

Hi Dzianis,

Can you please elaborate on the way that you are setting your custom string values in the control and if you were able to isolate the exact cause of the problem?
