Unfortunately, since all buttons are emitted as "Submit" buttons, we find that the
validation will occur for all button controls, and it's only possible to
enable/disable validation caused by the buttons and not selectively fire required
field validators depending on the button. There is a way though, and that is using
CustomValidators instead of required field validators. This is how it's done: Say
you have 2 buttons btn1 & btn2. btn1 causes validation for textbox txt1 and btn2
causes validation for textbox txt2. Now, create 2 custom validators for each text box,
say cv1 for txt1 and cv2 for txt2. Specify the client-functions for each custom
validator, say fnValidate1() and fnValidate2() respectively - <script> function
fnValidate1(args, isValid) { //validate txt1 for empty.
if(document.forms[0].txt1.value.replace(" ", "").length == 0) { isValid =
false; } else { isValid = true; } } function
fnValidate2(args, isValid) { //validate txt2 for empty.
if(document.forms[0].txt2.value.replace(" ", "").length == 0) { isValid =
false; } else { isValid = true; } } </script> That's all to
it. Now the validators will fire only for the fields that are supposed to be validated
depending on the button pressed. Note: The replace() function above needs the
parameter for global search and replace (regExp object) instead of the strings as
shown, I have shown it that way just for the sake of explaining.
