Hiii,
I have used required field validator in my form inside update panel.
I want to set Reqrd Validation for Dropdown also and Date Regular Expression for date textboxes.
Every Textbox have TextChanged Event for setting Focus to next Textbox.for that purpose i have to set AutoPostBack="true" for every textbox.
But its not working fine inside the update panel.
If i directely clicks on save button it throws all validators correctly but when i started to fill empty textboxes then it automatically removes all validation error.
it means if 3 textboxes fires reqd validation when clicked on save button and then user starts to fill textbox1 then it automatically removes other 2 textboxes reqd validation error immediatly.
I think it is a Postback issue for that i have added CausesValidation="true" and Validation Group="AllFields" to every textbox and Also called Validation Group on Save Button.
But still it in not working.
