Hi, First it's a common idea to do so but this may cause one usability problem which may make the user frustrated, as for example if you are entering one numeric value into a textbox and you add one validator for this textbox if the user enters an invalid value and presses tab the validator will fire and as the value is invalid the user will not be able to leave this textbox until he enters a valid value, so I recommend that you write on JS function that fires once you try to submit the page and change the bgcolor of all invalid entries to red this may be more better, but if you need to do the focus stuff you can simple write something as : document.Form1.txtKeyWord.focus(); and I think this has been recovered in ASP.NET 2.0 as you can set the focus to one control right from server side code.
