The RadTimePicker allows the developer to get the value selected by the user in two ways:
Getting the Value as DateTime
In order to get the selected time as a DateTime you have to use the Value property of the RadTimePicker control.
DateTime value = this.radTimePicker.Value;
Getting the Value as String
In order to get the selected value as String you have to use the ValueString property of the RadTimePicker control.
string valueString = this.radTimePicker.ValueString;
The ValueString property returns a string representation of the currently selected value in the control
formatted according to the pattern set to the DisplayValueFormat property.
