We have implemented a validation through data annotation on a RadMaskedTextInput using this link: http://docs.telerik.com/devtools/wpf/controls/radmaskedinput/features/validation/regex
We are having an issue when we are implementing it with a custom control.
In the provided solution when RadMaskedTextInput, one is provided through the custom control and the other one is directly in the MainWindow.
The first RadMaskedTextInput (from the custom control) does not validate the data.
The second RadMaskedTextInput is validating the data when we are directly typing in it.
we suspect that it is related to the fact that we are binding through a dependency property
How can we modify the custom control to trigger the validation on the property?
Thank you for your help
