I have come across a strange validation error in windows web browser control. basically i am navigating to a secure website in browser and there is a textbox where when you click a calender pops up.

when you select a date and click submit it clears the textbox field and validation error pops up preventing the form to be submitted. I tried it in IE and the validation doesnt show when the textbox has a date.

for some reason the textbox gets cleared on submition in webbrowser control. anyone has any tips on this?
