Using the SfNumericTextBox in a WinForms form with Visual Studio 2019. On the designer I set the default Value to 100000 and I see that reflected on the Text property at design time.

At runtime, I programmatically set the Value property to something else, say 50000 and with debug I see that the Value property is as I set it. However, the Text property does not get updated to reflect the new Value, instead the Text property maintains the old value I had set during Design time.
