RadMaskedEditBox: ValueChanging event is not fired with MaskType.Standard

Use the following code to setup RadMaskedEditBox. When you start typing you will notice that the ValueChanged event is fired but the ValueChanging is not: 

            this.radMaskedEditBox1.MaskType = MaskType.Standard;
            this.radMaskedEditBox1.Mask = "AAAA";

            this.radMaskedEditBox1.ValueChanged += radMaskedEditBox1_ValueChanged;
            this.radMaskedEditBox1.ValueChanging += radMaskedEditBox1_ValueChanging;

        private void radMaskedEditBox1_ValueChanging(object sender, CancelEventArgs e)

        private void radMaskedEditBox1_ValueChanged(object sender, EventArgs e)

Hello, David,     

Thank you for reporting this.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to use the following code snippet:

FieldInfo fi = typeof(StandartMaskTextBoxProvider).GetField("provider", BindingFlags.NonPublic | BindingFlags.Instance);
StandartCharacterMaskEditBoxProvider provider = fi.GetValue(this.radMaskedEditBox1.MaskedEditBoxElement.Provider) as StandartCharacterMaskEditBoxProvider;
provider.InsertKeyMode = InsertKeyMode.Overwrite;
