The && logical operator is not working or is it me?

Hi, I'm using vs2012
Please see attached code.

This value,  gridEditUser.Enabled.Value, is false.  I double check it in the debug mode.  The rest of the || condition would evaluate to be true.  Problem that is blows my mind that it apparently evaluate to be true and went on to process the rest of the code.

I am looking at it closely. But AND in English writing translates to OR in programming.

It is like executing items to by per this select statement:

Select Fruit From Produce
Where Fruit = 'Apple' OR  Fruit = 'Orange'

This person was told Apple and Orange. So he will have Apple and Orange in the list.

The following will have nothing to return:

Select Fruit From Produce
Where Fruit = 'Apple' AND  Fruit = 'Orange'

try this:

           
     if( gridEditUser.Enabled.Value && ( (String.IsNullOrEmpty(gridEditUser.Surname)) || (String.IsNullOrEmpty(gridEditUser.GivenName))  || (String.IsNullOrEmpty(gridEditUser.MiddleName)) || (String.IsNullOrEmpty(gridEditUser.VoiceTelephoneNumber)) ) )
                {
                    e.Cancel = true;
                    lblError.Visible = true;
                    lblError.Text = "First Name, Last Name, Middle Name and Cell Phone fields are all reqired.";
                    return;
                }

Maybe that holds in SQL only, your testing will determine if it is the same in procedural programming.

Typos fixed...

It is like executing items to buy per the list produced by the select statement below:

Select Fruit From Produce
Where Fruit = 'Apple' OR  Fruit = 'Orange'

This person was told to buy Apple AND Orange. So he will have Apple and Orange in the above list to buy

But, the following will have nothing to return, so he will not buy Apple or Orange.

Select Fruit From Produce
Where Fruit = 'Apple' AND  Fruit = 'Orange

Thank you.  I thought I was losing my mind.  I was just missing the parenthesis.
