asp.net - form control values are not reloaded on postback -
i in process of migrating user controls 1 version of project new version. there errors in project while trying change version, created new project , started copying pages , controls. have got of controls copied over, , in process of copying on pages. testing go.
with being said, working on control , noticed having problems required field validators. these fields not dynamic, there. fields failing tests required validators had data in them. there 3 having problems. 3 text fields. able convert 2 of validators custom validators , able them working, third still not work.
the custom validator not working fails because value page not reloaded in control. when check posted form using control's unique id, data exists. cause disconnect? understand controls supposed reloaded post data before control's events fired. appears process broken. happening?
the fields in question txttitle, txtdescription, , txtsendnoticeto.

change function this:
