Asp.net Validation With Validation Group Calling Page_clientvalidate Not Working As Expected

Hi I am calling the following javascript when user clicks complete button which is to call validation on all of the validation groups which i have 3. but what is happening is that

Solution 1:

See Page_ClientValidate() with multiple ValidationGroups - how to show multiple summaries simultaneously?

Edit

Can't you just call Page_ClientValidate() (without any arguments) to validate all controls on the page?

Solution 2:

I know this is an old post, The issue with using only Page_ClientValidate() is that, if you want to validate one group at a time, it won't work as it fires all the validation groups, you can do something like this,

function something(){
  if(Page_ClientValidate('Save'))
  {
     //Your Code
  }
  elseif (Page_ClientValidate('Group2'))
  {
     //your code
  }
  else
  {
     //your code
  }
};
