.NET Forum / Windows Forms / WinForm General / August 2006Binding NumericUpDown.Value to an app setting only works in one direction
Using Visual Studio 2005, I've placed a few NumericUpDown controls on a form and bound their Value properties to user-scope application settings. The bindings seem to work fine at design time, but only work in one direction at runtime. When I open the form, the control values are correctly set, but changing the values does *not* update the app settings! Closing the form and/or calling Properties.Settings.Default.Save() doesn't help. What's the deal?

This seems like a glaring bug in the app setting bindings: the setting value is copied into the control, but the only way to get the changed value from the control back into the app setting is by copying it manually in a ValueChanged (or FormClosing, etc.) event. The bug doesn't seem to occur with other controls. Jesse Free MagazinesGet these publications absolutely FREE for up to 12 months. There are no hidden fees and no obligation.
