I need only days.nothing else.

Thanks for your reply.You solution works well for any values.But I have to work with dates. I've two text box startdate and enddate. I will input two date into two text box one is txtBoxStartDate and another one txtBoxEndDate. I want to show the duration of these two dates after I click on duration text box. Can you please tell me the whole procedure using javascript or jquery? I know the calculation in C# but as I'm a beginner of javascript,so I need your help.

Thanks for your ans. It's not working the way I need to.I've two text box startdate and enddate. I want to show the duration of these two dates after I click on duration text box. I know the calculation but I don't know how to automatically put the duration value after just a single click on duration textbox.

I've got this error after using your solution.
Compiler Error Message: CS1061: 'Telerik.Web.UI.RadDatePicker' does not contain a definition for 'Value' and no extension method 'Value' accepting a first argument of type 'Telerik.Web.UI.RadDatePicker' could be found (are you missing a using directive or an assembly reference?)

The code is like this-
string user = Session["username"].ToString();
string type = DropDownListType.SelectedValue.ToString();
TimeSpan ts = RadDatePickerStart.Value - RadDatePickerEnd.Value;
durationTextBox.Text = ts.Days.ToString();
