I have 2 textboxes in my page. One is supposed to hold the Date and the other Time. These 2 data are merged when saving into one database field having a datetime datatype. Upon retrieve, the datetime field value is split into 2 and put into the Date Textbox and Time TextBox.
Upon input, when I am trying to update, the validator always says "Invalid Time."

I am using a MaskedEdit extender for a datetime entry. However, in case of invalid input of date and time, how am be able to validate it through the use of Ajax and validation will occur when the user clicks on the submit button.
View 5 RepliesIs it possible to validate a date format when you use a form view to enter the record into the database? I have a form view that is used to sign out for the day or week. I need to dates to be in mm/dd/yyyy format. Is there someway to use the validation controls so that it won't let you enter the record unless it is correct and will prompt them to enter the right info.

View 1 RepliesI'm using Telerik's RadScheduler Control with WebService Binding.
I've used RadScheduler with Server Side Binding which has an event called "OnTimeSlotCreated" which fires every time when a particular time slot creates so that i can access the time slot and get the control (HtmlTableCell Control) to modify it according to the requirement.
But now i'm binding it from client side through WebService which has no such "onClientTimeSlotCreated" event, also these time slots are not having any identity at client side to access.
