Question: I have a textbox.In its onclick iam calling a javascript fn to call calendar.Texbox is readonly. Clicking on textbox calendar is coming and value is showing in textbox. But on clicking submit button where I have written code to save, there i am not getting value in textbox. What may be the reason for that?

Answer: 
I suspect that your text box has the [disabled](http://www.w3.org/TR/html401/interact/forms.html#h-17.12.1) attribute instead of [readonly](http://www.w3.org/TR/html401/interact/forms.html#h-17.12.2) which prevents it from posting its value to the server.
You can get the value by using

```
Request.Form[YourTextBox.UniqueID]

```
