Syncfusion DoubleTextBox - NegativeColor

Question

using doubleTextBoxes from Syncfusion i am using the NegativeColor attribute to specify different textcolors for negative values. This works fine if i type in a negative value manually in my textboxes. However i have some textboxes that are filled automatically by DataBinding:

this.txtExample.DataBindings.Add(this.txtExample.GetPropertyName((x) => x.BindableValue), mViewModel, mViewModel.GetPropertyName((x) => x.TestProperty)); 

I tried binding my Property to "Text" and "DoubleValue" instead of "BindableValue", but the text color is not changing for negative values. Any Ideas why the DoubleTextBoxes are behaving this way?

I have tried the same with the Syncfusion DoubleTextBox and the Negative color applied properly in the reported case.

Here is the sample and code snippet for your reference.

    class ViewModel
{
    Form1 frm = new Form1();
    Data data = new Data();
    public ViewModel(Form1 _frm)
    {
        frm = _frm;
        foreach (Control ctrl in frm.Controls)
            if (ctrl is DoubleTextBox)
                (ctrl as DoubleTextBox).DataBindings.Add("Text", data, "unit");
        Application.Run(frm);
    }
}

public class Data
{
    private double n_unit = -5;

    public double unit
    {
        get { return n_unit; }
        set { n_unit = value; }
    }
}
