Textbox with redirect

Show allHide all

Used to help users avoid creating duplicate entries for a given entity, for example two members with the same personal identity number.

The control looks like a normal textbox but when its value is changed it calls the control's stored procedure, which can choose to show a prompt offering to forward the user to another menu item.
