C#

hi..i have two radgrids and there are several tabs.Requirement is that on clicking first tab,one grid is to be shown and on changing tabs, other grid is to be shown.

Now the problem is on changing tabs,both grids are shown.
So how can we hide one grid.

What I have tried:

 string tabId = e.Tab.PageViewID;
            RadPageView pageView = (RadPageView)RadMultiPageClasses.FindPageViewByID(tabId);
            pageView.Controls.Add(RGridMappedDocument);
RGridMappedDocumentSecond.Visible = false;
            RGridMappedDocument.Visible = true;

RGridMappedDocument.Rebind();
