Server-side events do not fire the first time after client-side validators have fired

[Stuart Whiteford]

Hi,

I asked this back in January without answer and forgot about it until now.

I've got a basic web form, two textboxes, a couple of radio button groups,
some required field validators, and a Submit and Cancel button.

When the page loads, if I click the Cancel button, the server-side event
fires as normal.

However, if I click the Submit button (with no information entered) the
client-side validators fire, but if I then decide to press the Cancel
button, nothing happens, I need to press it a second time before the
server-side event fires.

I've now noticed that no server-side events fire the first time after the
client-side validation has fired. Not so much of a problem with a Cancel
button, but a nightmare for DropDownLists with AutoPostBack enabled!

TIA,
Stuart.

hello,

if isValid is false, the server side code should never fire?

Hi,

It's not the server code that would fire if the page was valid, it's any
server-side code on the page.

Once the validator have fired client-side, I then go and change a
DropDownList with AutoPostBack enable, and the PostBack does not happen (the
CausesValidation is false on the DropDownList).
