When a while loop checks its state

Hi, I have something like: Version 1:

bool noErrors = true;
while(noErrors)
{
   noErrors = ValidateControl(txtName);

   // other code
}

Version 2:

bool noErrors = true;
while(noErrors)
{
   if(!ValidateControl(txtName)) break;

   // other code
}

I use this code to validate the form, and if the validation returns false, I want to break it before executing the “other code”. Since I don’t know when the loop checks its state, I don’t know which makes more sense. Should I use the first or second version, or perhaps the third?

thank you for your time

Version 2 will be broken before launch //other code. Version 1 will not be checked until the next iteration begins.

bool noErrors = true;
while(noErrors) 
{    
    noErrors = ValidateControl(txtName);     
    // other code 
}

Checks before each iteration.

bool noErrors = true;
do 
{    
    noErrors = ValidateControl(txtName);     
    // other code 
} while(noErrors);

Checks after each iteration.

. , , , txtName ? - ?

while (ValidateControl(txtName)) 
{
    // other code 
}

txtName , ,

if (ValidateControl(txtName))
{
  while(/*Some other condition*/)
  {
      // other code
  }
}
