Well, when do you want to call Validate? Generally, I'd say you'd call a Validate method when you leave the control. If that's the case, you don't need to call it manually, just have the control call it by itself.
I have created a class called DatePickerEx.cs that inherits from DatePicker class. Then I created a UserControl called CustomDatePicker.xaml that references the DatePickerEx.cs class in the xaml code.If I bind the "selecteddate" property in xaml at this point, it works good. So far so good.
Now, I reference the CustomDatePicker.xaml usercontrol inside another UserControl, at this point I have no way to set the "SelectedDate" property on the new UserControl called CustomDatePicker.xaml, can someone explain me how can I expose the DatePickerEx.cs->DatePicker.cs SelectedDate property via the new userControl CustomDatePicker.xaml to any other consumers of CustomDatePicker.xaml.
I need to use some kind of Dependency Property to achive this?
If you did public class DatePickerEx : DatePicker, then you'll get all the public properties and methods of DatePicker. If that's not working, you did something wrong . Not sure what since you didn't post what errors you are getting or any code.

I am attempting to create a common WPF logon dialog. I have the dialog as a separate DLL which access a service and returns the user permissions. This works except the dialog displays as an independent window. I want to pass the main window to the dialog as the owner.
I call the logon dll from the main viewmodel
new IFALogon.LogonDlg().DoLogon(MainUI.AppID, "Finance NPA");
if (IFALogon.LogonVM.DBUser == null)
How can I pass the main view to this DLL.
Never underestimate the power of human stupidity
