DevExpress

hi there ,im currently building a ribbon application using Devexpress , There is the scenario : ive the main form containing Ribbon control with diffrents buttons , each button opens a userControl which contains as well differents controls such textboxes , buttons,XTragridControl and Ive a splittercontainer onto the main form which divides the container into 2 panels , the first panel contains a navigation bar , within each navigation bar group i have different textboxes and buttons with the only purpose of firing searche events. , however i Clear and add the panel2 with different UserControl according to the button pressed in the ribbon. the first Ribbon button opens the UserControl(Lessee) this usercontrol contains an Xtragrid control populated with data , i want to peform a search eg:"by Name for instance , from the navigation bar contained in the panel1 main form . what i did is I've tried to access the different textboxes of the main form navigation bar , from The UserControl(Lessee) where i have created a public Search function ,and then accessed back this function in the main form in The SearchButton Event. The result i got is an Empty Grid with no data just fields name. anyone has a better approach?
