I am trying to implement ValidatorCalloutExtender to the RequiredValidator controls.
I can say it is working, but i cannot find a way to show all ValidatorCalloutExtender at the same time.
When I click submit button, all RequiredValidator controls are fired but only first ValidatorCalloutExtender control is visible. To activate the others, user needs to click other controls, then related ValidatorCalloutExtender controls pupup.
How to show all ValidatorCalloutExtender multiple controls?
