We have used C1DateEdit control(Component One third party control) in WPF application and it has some issue with it.

Please find below the scenario and the issue.


Scenario 1:

Step 1 : Create a WPF-Windows application and add Window1.xaml .

Step 2 : Add C1DateEdit control in WindowsFormsHost element.

Step 3 : Execute the application.

Step 4 : Click on the dropdown of the DateEditControl. It throws the below exception.





Scenario2:

Step 1 : Create a WPF-Windows application and add Window1.xaml .

Step2: Create a usercontrol(ucDateTimePicker.cs) by adding C1DateEdit control.

Step3: Add the user control in WindowsFormsHost element of Window1.xaml.

Step 4 : Execute the application.

Step 5 : Click on the dropdown of the DateEditControl. It throws the below exception.



Expected Result:

When click on the dropdown of the DateEditControl, it should drop the calendar.



Exception:

System.NullReferenceException: Object reference not set to an instance of an object.

at C1.Win.C1Input.C1DropDownControl.OpenDropDown()

at C1.Win.C1Input.C1DropDownControl.a()

at C1.Win.C1Input.C1DropDownControl.WndProc(Message& m)

at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)

at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)

at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)



Note: The same scenario works well with Windows application of visual studio 2005.



Kindly provide the idea/solution for this issue as early as possible.
