Here I will explain how to get read only control values in codebehind using asp.net
Description
If we set ReadOnly="true" property for textbox it won’t give any chance to enter value or change the existed value .If we try to get data in textbox server doesn’t process the read only text box because the value of the text property is preserved in the view state between postbacks unless modified by server-side code. In some situations we don’t want give chance to user to enter data except from calendar control in that situation we need to set that textbox read only in serverside like this
