So, I have a RadDock setup. In the hosting main window there is a radmenu followed by a radtoolbar where I have a toolbarbutton for saving. Below that I have a raddocking that has a pane that hosts my usercontrol that contains, among other things a the RadDateTimePicker shown below. It works great except in one odd condition. If the txtClosedDate has a valid value and the user blanks it out and then hit's the button in the toolbar without clicking or tabbing to another field, the null value is not bound back to the source and my viewmodel receives the original date value instead of null. If, however, the user goes to any other field on the user control, thereby forcing a lost focus event the correct binding happens. I have hacked around the problem with the following code, but I think you boys need to fix this on your side.
Thanks ... Ed
