Hello Umbala,
You can handle the ValueChanged event and set the value to zero, if the new value is null:

private void RadMaskedNumericInput_ValueChanged(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
if ((sender as RadMaskedNumericInput).Value == null)
{
(sender as RadMaskedNumericInput).Value = 0;
}
}

Hello Umbala,
Unfortunately the MaskedInput controls don't support this scenario. I logged this issue in our PITS under the name MaskedInput: When holding the Backspace and Delete keys, the Value property doesn't match the Text property and the item will be available for tracking in approximately 24hours. I also updated your Telerik account accordingly.
In the meantime you can try a couple of workarounds. You can handle the MaskedCurrencyInput.KeyUp() event and reset the control's Value whenever it is null or 0:
Or you can handle the MaskedCurrencyInput.ValueChanged() event to reset the control's Value again in case it is null or 0. But you will need to reset it in a Dispatcher:

i´ve implemented the suggested solution in the second post on a numericinput control.
but the control doesn´t fire the valuechanged event if the clear-button is clicked multiple times.
so the value still can get null. also my validation doesn´t work then.
any solution for that??

Hi CHRISTIAN,
The ValueChanged event will only fire when there is a change in the value. When you press it multiple times, the value does not change and stays null. What you can do, is to create your own Clear command and assign it to the control:

Hi Federico,
To achieve the described behavior you can set AllowMinusOnZeroValue property of the Mask to False:
You can find more information in this help article.
If the suggested approach does not work for you, could you please elaborate a bit more on your scenario by sending us a sample project or a code-snippet with the declaration of your MaskedInput. There are many combination, so for us is important to know:
- do you use RadMaskedNumeric or RadMaskedCurrenctInput;
- the value the Mask property (which Mask token, it is bound or not);
- have you implement some of the suggested approaches here (on KeyUp, ValueChanged, ClearCommand).
Thank you in advance for you cooperation.
