在tabclick上隐藏/显示gridview

Question

我有两个GridView，有几个标签。在选项卡click上，将隐藏一个网格，另一个网格将被显示。

我已尝试制作第二个网格visible=false - 但网格仍未隐藏。

protected void RadTabStripClasses_TabClick(object sender, RadTabStripEventArgs e)
{
    RGridMappedDocument.MasterTableView.FilterExpression = string.Empty;
    RGridMappedDocumentSecond.Visible = false;
    RGridMappedDocument.Visible = true;
    string tabId = e.Tab.PageViewID;
    RadPageView pageView = (RadPageView)RadMultiPageClasses.FindPageViewByID(tabId);
    pageView.Controls.Add(RGridMappedDocument);                            
    if(hiddenHeight.Value != "undefined" && hiddenHeight.Value != "NaN" && hiddenHeight.Value != string.Empty)
    {
        RGridMappedDocument.ClientSettings.Scrolling.ScrollHeight = Unit.Pixel(Convert.ToInt16(hiddenHeight.Value));
    }
    RGridMappedDocument.Rebind();
 }
