Need to generate the day name as a disabled text on a form each time I select a date from the date calendar text i.e. txt_Date on a form

I tried this, but had an error txt_Date.Text;

C#

protected void txt_Date_TextChanged(object sender, EventArgs e)
        {

            //String Test;

            DateTime Test = txt_Date.Text;
            DayOfWeek dow = Test.DayOfWeek;
            txt_Day.Text = dow.ToString();


        }

Any help please

Thanks

Since Text is a valid property of many controls, and specifically of the TextBox and Label controls - which are the ones you probably want to use for this - and you don't tell us what the error message is, the best guess is many fold:
1) You don't have any control called txt_Date. Create one.
2) txt_Date is not a Label or TextBox. find out what it is.
3) You can't just assign a string value to a DateTime - that doesn't work any more than you can push a square peg into a round hole. You need to convert it to a DateTime value first, preferably with validation.

C#

DateTime test;
if (!DateTime.TryParse(txt_Date.Text, out test))
   {
   ... report input problem to user ...
   return;
   }

If you are using a DateTimePicker to select the date, then us the Value property, which is already a DateTime:

C#

DateTime test = txt_Date.Value;

But change the damn name because that isn't a text based control...

Solution 2

C#

protected void cal_SelectionChanged(object sender, EventArgs e)
        {
            txtDate.Text = cal.SelectedDate.Date.ToShortDateString();
            txtDay.Text = cal.SelectedDate.Date.DayOfWeek.ToString();
        }
