Hi,

I have the following code:

DateTimePicker datum = (DateTimePicker)sender;

string HuidigeDatum = datum.Text.ToString().Trim();
if (HuidigeDatum == "")
{
MessageBox.Show("Datumveld is leeg.");

}

How to see if the field is empty. The code above doesn't work.

Since DateTime is not nullable, your string should never be "". Are you
getting an error, and if so, what is the error?
 
Hi Mike,

It is from a datetimepicker textbox. If I do not enter a value but leave it
on the date thats given the database gives an error that the field can not
be empty or null. Somewhere must a value be null or empty, but where?
